Telegram

Telegram is a messaging service for people who want to coordinate across devices, reach large communities or publish to broad audiences. It is strongest as a flexible, free communications hub; choose another service if you need end-to-end encryption in every chat or an account without a phone number.

Overview

Founded in 2013 and headquartered in Dubai, Telegram brings messages, photos, videos, file sharing and calls together in cloud-synced chats. That synchronization makes it practical to switch among devices, but it comes with a security distinction worth understanding: Secret Chats are end-to-end encrypted and stay on the devices involved, while cloud chats are stored encrypted on Telegram’s servers.

Telegram says it does not sell personal data or use it for ad targeting, and retains data needed to operate its cloud service. Accounts require a phone number. Encrypted backups and disappearing messages are supported. Users can turn to its FAQ or contact Telegram Support for help.

Key features

Groups and channels: Groups can hold up to 200,000 members, and channels can broadcast to unlimited audiences. That scale makes Telegram a strong fit for communities and announcements, though large reach is not a substitute for end-to-end encryption.

Calls: Voice and video calls are end-to-end encrypted, and group calls support up to 200 participants. The group-call limit is ample for many teams and communities, but it is not unlimited like channel reach.

File sharing: Ordinary users can upload files up to 2 GB each. That is generous for routine sharing, but users who regularly send larger files need Premium’s 4 GB cap.

Bots and Mini Apps: Bots can connect business tools and workflows, while Mini Apps can integrate third-party services, APIs and devices. These options make Telegram more adaptable for organizations than a chat-only service, provided they are willing to build or adopt integrations.

Developer tools: An open API and Bot API support apps, specialized tools, integrations and payment features. This is a meaningful advantage for developers extending the service, rather than a reason by itself for a casual user to switch.

Pricing

Telegram is freemium, with a broad free tier and an optional Premium subscription. The free plan costs nothing, billed Free to use. It includes unlimited cloud storage, groups and channels, voice and video calls, and multiple devices and accounts; ordinary file uploads are capped at 2 GB each.

Telegram Premium has no single published price: subscriptions are monthly or yearly, and the price varies by country and provider. It adds 4 GB file uploads, faster downloads, doubled limits and exclusive features. A yearly subscription is discounted, but the amount depends on the purchase route, which can be the App Store, Google Play or @PremiumBot. Premium makes sense for frequent large-file senders or people who would benefit from the higher limits; the free plan remains the better fit if its caps suffice.

Platforms

Telegram supports Android, iOS, Linux, macOS, Windows, web and API access. Desktop apps and multi-device support suit people who move between phone and computer, while the API offers a route for custom integrations. Phone-number account setup remains a constraint regardless of platform.

Who it's for

Telegram suits people organizing large groups, publishing channel updates, sharing files across devices or connecting business workflows through bots and Mini Apps. Small teams may find its groups, usernames, desktop apps and file sharing useful for communication. It is a weaker choice for users who expect every conversation to be end-to-end encrypted: that protection applies to Secret Chats and calls, not cloud chats.

Pros and cons

Pro: Groups of up to 200,000 members and unlimited-audience channels support unusually broad community coordination and broadcasting.

Pro: The free plan includes unlimited cloud storage, calls, groups and channels, plus multi-device and multi-account use.

Pro: Bots, Mini Apps and open APIs give businesses and developers ways to connect existing workflows and build specialized tools.

Con: Cloud chats are server-stored and encrypted there, not end-to-end encrypted; users seeking that protection for every chat should look elsewhere.

Con: A phone number is required to create an account, which rules it out for users or teams avoiding phone-based registration.

Con: Free uploads stop at 2 GB per file, and Premium pricing varies by country and subscription provider, making the upgrade less predictable.

Alternatives

For a broader shortlist, see Secure Messaging Apps. Consider Olvid if you want a free plan with unlimited messages and attachments, secure group discussions and ephemeral messages. Wire is another freemium option, with source code Wire describes as fully open source and available on GitHub for verification.

Threema is a paid alternative with a free trial and open-source apps. Choose Viber if free messaging and calls specifically to other Viber users meet your needs. Crypho may suit personal use that fits its free plan’s 3 MB file limit and one-group cap, with encrypted calls and video calls.

Jami is a free alternative. SimpleX Chat is also free, with alternative clients based on its code required to publish modifications under AGPLv3. Keybase is a free option whose download page describes it as open source and links to its source code.

Verdict

Choose Telegram if you need a free, cross-device service for large groups, broad broadcasts, calls and extensible workflows. Its combination of generous free features and developer tools is compelling, but the separation between Secret Chats and cloud chats is decisive: look elsewhere if end-to-end encryption across every conversation is your priority.
