Top 10 Cons & Disadvantages of Telegram

Telegram reports more than one billion monthly active users, a milestone its founder Pavel Durov announced in 2025, making it one of the largest messaging apps on earth. Beneath that growth lie trade-offs in privacy, encryption, and usability that users often discover later. Standard chats are not end-to-end encrypted by default, and account recovery rests on a single phone number, so the risks matter.

This article breaks down the ten most common downsides, pairing each with a realistic scenario and a practical fix you can apply right away. It also compares Telegram against WhatsApp and Signal, then covers the security habits that close the biggest gaps. By the end, you can judge whether Telegram fits your needs or whether a more private messenger suits your own situation.

What Is Telegram?

Telegram is a cloud-based messaging app launched in 2013 that balances speed, cross-device sync, and feature depth. Rather than encrypting everything on the device, it keeps most history on its servers so you can access chats from any gadget. That convenience defines the platform and explains several trade-offs below. Telegram is fast and open, yet cloud storage shapes its privacy position.

A few core traits shape how the platform operates for users:

Open-Source Design: Some aspects of Telegram are open-source, allowing developers to explore its structure.
Multi-Platform Support: It works smoothly on iOS, Android, Windows, macOS, and Linux.
Large Group Chats: Telegram supports groups with up to 200,000 members.
Cloud-Based Storage: Messages, files, and media are accessible from any device.
Customizable Features: Options like themes and bots provide personalized user experiences.

Real-Life Example: A distributed team uses Telegram daily to coordinate across time zones, sharing files in a large group. Members like that history follows them between phone and desktop, yet they rarely ask where messages live. That cloud convenience they value is the same design that later limits end-to-end privacy across the service and every chat they start.

Disadvantage #1: Privacy Concerns

Telegram advertises itself as secure, but its privacy guarantees narrowed in 2024, and its encryption methods have raised eyebrows among privacy advocates because standard chats lack end-to-end encryption. ESET’s explainer on Telegram privacy confirms that cloud chats are encrypted on servers, meaning Telegram holds the keys and could read them. That design also stores your metadata centrally, which privacy-conscious users find hard to accept.

Security gaps appear in three clear patterns:

No Default Encryption: Standard chats are not end-to-end encrypted by default, meaning Telegram can access their contents on its servers.
Server-Side Storage: Messages are stored on Telegram’s servers, posing potential risks to user data if those servers are compromised or breached.
Metadata Collection: Telegram gathers usage metadata such as IP addresses and contact information, which privacy-focused users may distrust.
Law Enforcement Sharing: Since September 2024, Telegram has disclosed IP addresses and phone numbers of suspected offenders when legally required, a policy shift on user data that narrows its former guarantees.

Real-Life Example: A journalist contacting a confidential source used a regular Telegram chat without realizing it was not end-to-end encrypted. The conversation stayed on Telegram’s servers with metadata intact, exposing the exchange to a level of risk the source had never agreed to. A switch to a Signal conversation restored the protection the story required.

Solution: Move sensitive discussions to Secret Chats, which use end-to-end encryption, and keep ordinary messages free of confidential detail. Better yet, choose a messenger that encrypts all chats by default for high-risk conversations. Review your active sessions and revoke devices you no longer use so a lost phone cannot quietly expose stored history.

Disadvantage #2: Limited File Compression Control

File sharing is convenient, but Telegram lacks robust compression control for images and video, which quietly degrades quality that designers depend on. Media sent in chats is often resized and compressed to save bandwidth, and there is no reliable way to stop the app from eating through data. Photographers and creatives notice the fidelity loss immediately when they open received files.

Compression issues show up in a few common ways:

Reduced Media Quality: Image and video compression may degrade the quality of photos and clips you share, weakening their fidelity.
No Granular Control: There is no granular control over compression levels for media, so you cannot choose a higher-quality setting.
Heavy Data Use: Large files can result in excessive data usage that quickly consumes mobile data allowances and connection limits.

Real-Life Example: A photographer shared high-resolution proofs with a client through Telegram, only to find the images arrived visibly softer after automatic compression. Fine texture and color were lost, which forced a second upload through a file service that preserved original quality and delayed the final review of the work.

Solution: Send critical media as documents rather than as photos, which stops Telegram from re-encoding them, and confirm the original file size arrived intact. For portfolio work, pair Telegram with a dedicated file host and paste a download link instead. Keep compression for casual sharing where perfect fidelity does not matter.

Disadvantage #3: No Default Two-Factor Authentication

Telegram provides an option for two-factor authentication (2FA) but does not enable it by default, so most accounts depend on a one-time SMS code. Carriers can be tricked into porting a number, which lets an attacker intercept that code and seize the account. Because many users never enable the extra password, Telegram accounts remain far easier to hijack than they should be.

Account security suffers from three weak defaults:

Weak Default Protection: Accounts are only secured with a one-time SMS code by default, leaving them vulnerable to interception.
SMS Interception Risk: SMS-based authentication can be intercepted by attackers, allowing them to seize control of an account.
Little User Awareness: Many users are unaware of the 2FA feature and therefore never enable the extra password protection.

Real-Life Example: A user lost their Telegram account when an attacker ported the linked phone number to a new SIM and intercepted the login code. The hijacker reached private group history and impersonated the owner before two-step verification was finally enabled. The breach took days to undo and damaged trust in the account holder’s channels.

Solution: Turn on two-step verification in Settings and add a recovery email so a lost phone cannot lock you out. Avoid relying on SMS alone and keep your linked number current with the carrier whenever it changes. Enable active-session alerts so any unexpected login triggers an immediate response before the damage can spread any further.

Disadvantage #4: Limited Discoverability of Channels

Telegram channels are a unique feature, but finding them is not straightforward because the app provides no dependable in-app directory. There is no browse-by-category catalog or verified channel search, so users fall back on external websites and shared invite links. Newcomers especially struggle to separate active, quality communities from abandoned groups that are cluttered with stale posts.

Poor discovery creates several practical frustrations:

No In-App Directory: Telegram lacks an in-app directory for channel discovery, so finding channels by category or topic is difficult.
Reliance on External Sites: Users often rely on external websites to find relevant channels, producing inconsistent and unreliable results.
Steep Learning Curve: This reduces accessibility for newcomers unfamiliar with the ecosystem and where quality communities live.

Real-Life Example: A new user spent an evening hunting for a community channel on a topic they cared about, only to land on inactive or spam-filled groups. External search results were inconsistent, and nothing told them which channel was authentic or current. They nearly gave up before a friend forwarded a reliable invite link.

Solution: Use trusted third-party directories and verify a channel’s member count, posting frequency, and pinned history before you join it. Bookmark the channels you trust and rely on official invite links that come straight from known sources or the community itself. A proper in-app directory with categories and moderation would remove most of this guesswork.

Disadvantage #5: No Built-In Video Call Recording

While Telegram allows video calls, it doesn’t support recording these calls directly within the app, so you must install separate screen-capture software to save a session. That extra tool often produces poor audio, misses system sound, or fails partway through an important call, which complicates meetings you may need to revisit later. Teams that depend on reliable records find Telegram less competitive than rivals.

The missing recorder creates practical pain points:

Cumbersome Third-Party Tools: Recording requires third-party tools, which can be cumbersome to install, configure, and use reliably.
Competitive Disadvantage: This limitation makes it less competitive compared to other messaging apps that offer native recording.
No Record for Review: Video call participants cannot review discussions afterward because no recording is saved automatically.

Real-Life Example: A remote team ran a crucial planning call on Telegram and later realized nobody had recorded it. The one attendee who tried a third-party recorder captured only silence because system audio was misconfigured. Key decisions made during the meeting were lost, and the team had to reconstruct the plan from memory.

Solution: For meetings you may need to revisit, switch to a tool with native recording and transcription, and assign a backup note-taker. If you must stay on Telegram, test your recorder’s audio settings before the call begins. Treat any call as unrecorded until you confirm the capture actually works as expected.

Disadvantage #6: Lack of Threaded Conversations in Groups

Large group chats can quickly become chaotic because of the absence of threaded conversations that dedicated work tools provide. When many people post at once, answers detach from the questions they address and important updates vanish under unrelated chatter. Moderators burn hours re-sorting conversations that a simple thread structure would have kept organized and easy to follow.

Threading gaps disrupt busy groups in visible ways:

Lost Replies: Replies often get lost in busy groups, detached from the questions they were meant to answer.
Hard-to-Follow Discussions: Important discussions are hard to follow when messages arrive out of order and interleaved with other chatter.
Discouraged Engagement: It discourages meaningful engagement in larger communities because useful posts simply vanish in the flood.

Real-Life Example: Inside a busy tech-support group, a member asked about a persistent sync error while two unrelated debates ran alongside. Helpful replies arrived but attached to the wrong messages, so the original question got buried beneath the noise. The poster repeated the query three times before the correct fix finally surfaced from the chaos.

Solution: Move operational discussion to a threaded tool such as Slack or Discord while keeping Telegram for broadcasts and announcements. Within Telegram, use separate channels per distinct topic and ask members to quote the exact message they are answering. Clear reply conventions reduce the chaos that flat group chat inevitably creates across every busy community.

Disadvantage #7: No Message Scheduling for Regular Chats

Message scheduling in Telegram is restricted to Saved Messages or channels, so you cannot queue a note for an ordinary one-to-one chat. Professionals who want to time reminders, greetings, or follow-ups have to be awake to send them or rely on external bots. Rivals already let users schedule messages in any conversation without such workarounds.

Scheduling limits frustrate productivity-minded users:

No Scheduling in 1:1 Chats: You cannot schedule messages for standard 1:1 chats, only for channels and Saved Messages.
Reduced Productivity: This reduces productivity for users who want to plan messages but cannot queue them in advance.
Fewer Scheduling Options: Competing apps offer broader scheduling features, making Telegram feel limited in comparison.

Real-Life Example: A consultant wanted to send each client a reminder the morning of an appointment but could not schedule messages in direct chats. Instead, they had to wake early to type every reminder by hand, and on a busy day, one client was missed entirely. A simple schedule feature would remove the risk completely.

Solution: Use Telegram’s scheduler inside channels or Saved Messages for reminders, or run a bot that delivers timed messages to direct chats. If consistent scheduling matters, choose a messenger that lets you queue notes in any conversation. Plan your follow-ups the night before so nothing depends on you being online at the right moment.

Disadvantage #8: App Permissions Raise Concerns

Telegram requires extensive permissions during installation, which raises skepticism among privacy-focused users who question why a simple messaging app needs so much access. The app commonly asks for contacts, storage, camera, and microphone, which feels excessive when many rivals get by with far less. Without clear explanations of how each permission is used, cautious users assume the worst and look elsewhere.

Overreach in permissions worries cautious adopters:

Excessive Access: Access to the device’s contacts, storage, and camera is mandatory, which feels excessive for a messaging app.
Poor Transparency: There is a lack of transparency about how permissions are used and what the app does with the data.
Privacy Concerns: Some users feel this compromises their data privacy and choose more cautious alternatives instead.

Real-Life Example: A privacy-conscious user hesitated to install Telegram after reviewing the long list of requested permissions. Contacts, storage, and media access felt unnecessary for messaging, and the app offered no plain-language explanation of why each was needed. The user chose a leaner messenger that asked for almost nothing instead.

Solution: Deny permissions the app does not strictly need by adjusting access in your phone settings, and review them after every major update. Grant contacts and storage only when a feature genuinely requires them. Telegram should disclose why each permission exists and let users approve access granularly rather than all at once.

Disadvantage #9: Frequent Updates Can Be Confusing

Telegram frequently rolls out updates, and the rapid release cycle can confuse even loyal users who struggle to keep up with moving interfaces and new features. Each update may shift menus, alter gestures, or introduce tools with little in-app guidance to explain what changed. Newcomers and casual users alike find the constant churn disorienting rather than exciting or genuinely helpful.

Rapid releases create confusion in several ways:

Unclear New Features: Updates often introduce new features without adequate guidance on how they work or where to find them.
Disrupted Habits: Some updates can disrupt user habits by moving menus and changing familiar controls without warning.
Slow Adaptation: Novice users struggle to adapt quickly to the constant interface and feature churn between releases.

Real-Life Example: A user who finally learned where to find settings watched the layout change again after the next update. Menus moved around, a favorite option was renamed, and no tutorial explained the shift. Frustration grew to the point that the person considered switching apps simply to escape the churn.

Solution: Follow Telegram’s official channel or blog to preview what each release changes, and give yourself time to re-learn relocated controls. Turn on notifications only for major updates so you are not overwhelmed by constant alerts. Platforms that bundle changes and explain them clearly reduce the confusion that rapid iteration inevitably causes.

Disadvantage #10: Ads in Public Channels

Telegram has started integrating ads in public channels, a monetization shift that changes the once clean reading experience for millions of subscribers. Promotions appear between posts in popular channels, cluttering content and making communities feel commercialized. Users who valued Telegram’s ad-free image increasingly find the sponsored posts intrusive and hard to ignore while they scroll their favorite feeds.

Monetization affects the user experience in real ways:

Cluttered Interface: Ads may clutter the interface in popular channels, interrupting otherwise clean reading experiences.
Disrupted Content: They could disrupt community-focused content, making trusted channels feel commercialized and noisy.
Damaged Ad-Free Image: Some users feel this undermines Telegram’s ad-free image and its reputation among subscribers.

Real-Life Example: A subscriber scrolling a widely followed news channel was startled to see a sponsored promotion wedged right between the headlines. The ad felt out of place in a feed the reader trusted for distraction-free updates and clear reporting. That single interruption made the whole channel feel less trustworthy and noticeably more commercial overall.

Solution: Subscribe to Telegram Premium, which removes ads from the experience, if clean reading matters to you. Channel owners can also guide their audiences toward feeds that stay free of promotions. As advertising grows, expect more users to weigh whether the platform’s convenience still outweighs the rising commercialization and sponsored content.

Telegram Versus WhatsApp and Signal: Which Should You Use?

The choice comes down to what you value most, because each app protects data differently. CNET’s hands-on comparison shows Signal and WhatsApp encrypt all chats by default, while Telegram only encrypts Secret Chats. WhatsApp reaches the widest audience, Telegram offers the richest features and biggest groups, and Signal leads on privacy with the leanest interface.

Aspect	Telegram	WhatsApp and Signal
Default encryption	Only Secret Chats end-to-end	End-to-end by default
Cloud sync	Full across devices	Limited or none
Largest group size	Up to 200,000 members	Smaller, tighter limits
Feature depth	Bots, channels, themes	More minimal
Primary strength	Features and scale	Privacy by default

Use Telegram when you need massive communities, powerful bots, and convenient cloud history across devices. Choose WhatsApp for default-encrypted chat with the broadest network of contacts. Pick Signal when confidentiality is non-negotiable, and you can accept a smaller feature set. No single app wins everything, so match the messenger to the priorities that matter most.

How to Use Telegram More Securely

You can close most of Telegram’s biggest gaps with a few deliberate habits, even though the platform will not fix them for you. Security researchers at ESET outline Telegram privacy guidance that centers on Secret Chats and permission control. Start by enabling two-step verification, then audit what the app can access on your phone to reduce the largest risks.

Five habits measurably reduce your exposure:

Encrypt Sensitive Chats: Open a Secret Chat for confidential conversations so they stay end-to-end encrypted and never sync to the cloud.
Turn On Two-Step Verification: Add a password and recovery email so a stolen or ported phone number cannot unlock your account.
Limit Permissions: Revoke contacts, storage, and microphone access the app does not need, and review them after each update.
Send Files as Documents: Attach images and video as files to prevent automatic compression from degrading the original quality.
Check Active Sessions: Review logged-in devices regularly and end any session you do not recognize to stop silent account access.

Conclusion

Telegram remains a capable, feature-rich messenger, but its disadvantages deserve honest attention before you trust it with important communication. Privacy gaps, weak default security, compression limits, group clutter, and growing ads each create friction that affects individuals and teams alike. Knowing these limits lets you use the platform deliberately instead of discovering problems only after a costly mistake has already occurred.

You can manage most drawbacks with Secret Chats, two-step verification, permission audits, and careful file handling, while stronger alternatives cover the rest. Stay alert to policy and interface changes, review your settings regularly, and match the messenger to how sensitive your messages truly are. With the right habits, Telegram’s convenience does not have to come at the cost of your privacy.

Frequently Asked Questions About Telegram

Is Telegram end-to-end encrypted by default?

No. Only Secret Chats in Telegram are end-to-end encrypted, and they must be started manually for each conversation. Regular cloud chats are encrypted on Telegram’s servers, which means Telegram holds the keys and could technically read them. For fully private conversations, always use Secret Chats or switch to an app that encrypts everything by default.

Is Telegram safe to use for private or business messages?

Telegram is safe enough for everyday messages, but it is no longer the privacy fortress it once claimed to be. Since September 2024, the platform hands over IP addresses and phone numbers to authorities on valid legal requests. Enabling two-step verification, using Secret Chats, and auditing permissions meaningfully reduces risk. Teams handling confidential data usually choose Signal or a business tool with stronger privacy guarantees instead of relying on standard Telegram chats.

Can Telegram messages be recovered or read by Telegram?

Cloud chats stored on Telegram’s servers can be read because Telegram holds the decryption keys, while Secret Chats remain end-to-end encrypted and cannot be recovered from the cloud. If you delete a cloud message, Telegram removes it from its servers, but metadata may persist. For messages you never want readable, keep them in Secret Chats.

Why does Telegram compress images and videos?

Telegram compresses photos and videos automatically to save bandwidth and speed up delivery, which reduces file size but can lower quality. Sending media as a document attachment prevents most of that re-encoding and preserves the original file. Users who need perfect fidelity for proofs or portfolios should always attach files rather than send them as ordinary photos.

Is Telegram worth using despite its disadvantages?

Telegram is worth it for users who value huge group chats, channels, bots, and cross-device cloud history, and who accept its privacy trade-offs. Those who need default encryption, depend on reliable recording, or manage tightly regulated data may prefer WhatsApp or Signal. Understanding the ten disadvantages above helps you decide whether the convenience outweighs the risks for your situation.
