Telegram is a messaging app used for chats, large group discussions, broadcast channels and file sharing. It is popular for communities and channels rather than one-to-one messaging. It is also heavily used for scams in South Africa, which is worth understanding before joining anything on it.
What is Telegram?
Telegram is a cloud-based messaging app available on Android, iOS, Windows, macOS, Linux and in a browser. You sign up with a phone number, though you can hide that number and use a username instead.
The cloud-based design is what makes it different from WhatsApp, and it explains most of its strengths:
- Your messages sync across every device, including a full desktop app that works independently of your phone.
- There is no meaningful storage limit, so chat history and files persist indefinitely.
- File sharing is generous — individual files up to 2 GB, far beyond most messaging apps.
- Groups scale to 200,000 members, and channels are unlimited for broadcast.
On encryption, be precise, because this is widely misunderstood. Telegram’s ordinary chats are not end-to-end encrypted. They are encrypted between your device and Telegram’s servers, but Telegram can technically access them. Only “Secret Chats” — which you must start deliberately, one-to-one, on a single device — are end-to-end encrypted.
By contrast, WhatsApp and Signal are end-to-end encrypted by default. If privacy is your reason for choosing Telegram, that assumption is backwards — Signal is the stronger choice.
Groups versus channels is the other key distinction: a group is a conversation everyone can contribute to; a channel is a one-way broadcast where only admins post and subscribers read.
What is Telegram used for?
- One-to-one and group messaging, with text, voice notes, photos and video.
- Large community groups and broadcast channels, used by news outlets, businesses and interest groups.
- Sharing large files, up to 2 GB each.
- Voice and video calls, including group voice chats.
- Bots — automated accounts for reminders, alerts, downloads and customer service.
- Cross-device work, with a genuinely capable desktop client.
- Cloud storage of your own files, using the “Saved Messages” chat.
Its centre of gravity is communities and channels rather than personal messaging. In South Africa, WhatsApp dominates one-to-one and family group chat; Telegram is more often where people follow channels, join large interest groups, or need the file size and desktop capability.
Common tasks you can do with Telegram
- Start a Secret Chat for genuinely private one-to-one conversation, with optional self-destructing messages.
- Set a username and hide your phone number — worth doing on setup.
- Create a channel to broadcast to an audience.
- Use folders to organise chats, which helps once you have joined several channels.
- Schedule, edit or delete messages, including deleting for everyone with no time limit.
- Send large files without compression.
- Search across your entire history, which is fast and unusually thorough.
- Enable two-step verification — the single most important security step you can take.
Who Telegram is useful for
- People following news, interest groups or communities organised around channels.
- Group organisers, where WhatsApp’s limits are too small.
- People who need large file transfers, or a real desktop app.
- People wanting to be contactable without giving out a phone number.
- Businesses broadcasting updates, and developers using its bot platform.
It suits some people less well:
- Anyone assuming it is private by default — it is not, and that misunderstanding is the most consequential one.
- People whose contacts are all on WhatsApp, where a second app adds friction for little gain.
- People vulnerable to scams, for the reasons below.
When to choose Telegram instead of a related tool
Choose Telegram when you need large groups or broadcast channels, large file transfers, a strong desktop experience, or contactability without sharing a phone number.
Choose WhatsApp for ordinary personal and family messaging in South Africa, where almost everyone already is — and where end-to-end encryption is on by default.
Choose Signal if privacy is the actual priority. It is end-to-end encrypted by default, collects minimal metadata, and is the choice for genuinely sensitive conversations.
Choose Slack for workplace collaboration — threaded discussions, integrations and searchable team channels.
Choose Outlook or email for anything needing a formal record.
A necessary word on scams, because it is one of the most common reasons people search for this app.
Telegram is heavily used for fraud in South Africa, and the features that make it good for communities are the same ones that make it good for scammers: large anonymous channels, usernames instead of phone numbers, easy account creation, and limited moderation.
Common patterns to recognise:
- Investment and “trading” schemes — forex, crypto or “signals” groups promising guaranteed returns. Guaranteed returns do not exist.
- Fake job offers, particularly “task” or “review” jobs that ask you to deposit money to unlock earnings.
- Impersonation of banks, SARS or delivery companies.
- Romance scams, moving conversation off other platforms onto Telegram.
- Someone adding you to a group without asking, then messaging you privately.
- Unregistered sellers of medicines and other regulated products.
Practical protections: in Settings, restrict who can add you to groups; never send money to anyone you have only met online; treat any guaranteed-return promise as fraud; verify organisations through their official website rather than a link in a message; and enable two-step verification so your account cannot be taken over.
If money has been lost, report it to your bank immediately and to the SAPS. Speed matters with a bank transfer.

Frequently asked questions
What is Telegram used for? Messaging, large group discussions, broadcast channels, large file sharing, voice and video calls, and bots. It is stronger for communities and channels than for personal messaging.
Is Telegram encrypted? Ordinary chats are encrypted to Telegram’s servers but not end-to-end. Only Secret Chats are end-to-end encrypted, and you must start those deliberately.
Is Telegram more private than WhatsApp? Not by default. WhatsApp is end-to-end encrypted for all chats; Telegram is not. For genuine privacy, Signal is the stronger choice.
Why is Telegram used for scams? Large anonymous channels, usernames instead of phone numbers, easy account creation and limited moderation make it attractive to fraudsters — the same features that make it good for communities.
How do I avoid Telegram scams? Never send money to someone met online, treat guaranteed returns as fraud, restrict who can add you to groups, verify organisations independently, and enable two-step verification.
Is Telegram free? Yes. A paid Premium tier adds larger uploads and other extras, but the core app is free.
What is the difference between a group and a channel? A group is a conversation everyone can contribute to. A channel is a one-way broadcast where only admins post.
Can I use Telegram without giving out my phone number? Yes. Set a username and hide your number in the privacy settings — one of the more useful things to do on setup.
