Telegram lets you hide your phone number from nearly everyone you talk to, yet it won’t let you in without one. Signup runs through a code sent to a real number, and that number stays tied to the account long after you’ve forgotten which SIM you used.
If you’d rather not attach the SIM that also gets your bank codes, your pharmacy reminders and your family’s calls, the obvious fix is a second number. The less obvious part is that most quick ways of getting one are riskier than using your own.
Why Telegram wants a number at all
Telegram requires a phone number to register. The same number is also how a login gets confirmed on a new device: a code goes to it, and whoever reads the code gets in, unless a password stands in the way.
That second point is the one people skip. Picking a number for Telegram isn’t only about whether the signup code arrives today. It’s about who will control that number next spring, and whether they could use it to open your chats.
Then there’s plain privacy. Your main number is tied to your carrier account and is probably the one your bank has on file. Plenty of people don’t want it sitting behind a profile they use in large public groups.
The shortcuts that tend to go wrong
Search for a free Telegram number and you’ll find roughly three kinds of offers. Each can look like it works. The trouble shows up afterward.
- Public “receive SMS online” sites. The number is printed on a web page anyone can open. Anyone watching the same page can request a login code for an account registered there and take it over. Your account would be one refresh away from a stranger.
- Cheap one-time verification services. These rent you a number from a recycled pool for a single code. After your login, the number goes back to the pool, and the next user can receive your codes, including any future Telegram login code.
- VoIP app numbers. Numbers from apps such as Burner and Hushed are VoIP, and so are Google Voice and TextNow. Many services run a line-type lookup that returns mobile, landline or VoIP, and fraud teams often block VoIP because those numbers are cheap, disposable and rented in bulk.
Google Voice has an extra wrinkle. It requires a Google account and verification against an existing US non-VoIP number, which for most people means their main number. The thing you wanted to keep separate ends up linked anyway.
Whether a given VoIP number gets through Telegram’s signup is not something anyone can promise. The more useful question is control. With every option above, the number lives in somebody else’s system, and they decide what happens to it next.
Fragment +888 numbers
Telegram has its own answer: +888 numbers, sold on Fragment and paid for in TON. They work only inside Telegram, which is both the point and the main limitation.
If Telegram is the only place you need a separate identity, a +888 number is a coherent choice. The downsides are practical. You can’t use it to sign up for Signal, WhatsApp or anything else, and these numbers are expensive on the resale market. That’s a lot of money for a tool that does one job.
A second line on the phone you already carry
The middle ground between “my main SIM” and “a number I don’t really control” is a second line on the same handset. Most recent phones support dual SIM, either a physical SIM plus an eSIM or two eSIMs. Your main number stays where it is, and the second line handles Telegram.
One way to fill that slot is a prepaid carrier SIM. The US and the UK have no SIM registration law for prepaid SIMs. Many other countries, Spain and Germany among them, require ID for any SIM, and where registration is mandatory, using an unregistered SIM can itself be an offense.
The other is an eSIM that comes with a phone number. Read the listing carefully, because a lot of travel eSIMs are data-only. An eSIM with a number has both an IMSI, which is the subscription, and an MSISDN, which is the phone number itself. A data-only eSIM has no MSISDN, so there’s nothing for a signup code to land on.
A few providers sell eSIMs with a number included. Cypher eSIM is one example: a single eSIM carries calls in both directions, SMS and mobile data, and checkout asks for no account, no email and no ID. The number runs on a mobile network rather than inside an app, so it isn’t an app-based VoIP number. The plan card shows which country the number is from before you pay; European plans carry a French +33 number, and some destinations have local numbers. The team bought and tested its own number before selling it, and verification codes arrived. There’s a separate write-up on getting a number for Telegram and Signal this way.
Two caveats. These plans are time-boxed: the number lasts as long as the plan, so it’s a tool for a trip or a project, not a number to keep for years. And no provider can promise that a specific app will accept a specific number.
Also worth being straight about: a second number keeps your main number off your Telegram account, but it doesn’t make you anonymous. Every phone sends its hardware identifier, the IMEI, to the network, so a new eSIM on your main phone is not separated from your device. A no-KYC purchase hides who bought the line, not what the phone does. Separation at the network level takes separate hardware.
Lock the account down after signup
Once you’re in, the goal is to make the number matter as little as possible.
Start with a username. It gives people a way to reach you that isn’t a phone number. Then open Settings > Privacy > Phone Number and set it to Nobody.
The setting that matters most is Two-Step Verification. It adds a cloud password and stops someone who controls your number from logging in with one SMS. If your number came from anywhere other than a long-term line in your own name, treat it as mandatory, and use a password you don’t use anywhere else.
If you put Signal on the same second number, it has comparable tools. Signal added usernames in February 2024, and it has Registration Lock with a PIN. Turn both on.
Finally, think about lifespan before you choose. If you’ll want a fresh SMS code on this number years from now, a time-boxed plan is the wrong fit. If the account is for a trip, a project or a stretch of life with a clear end, a shorter-lived number is fine, as long as the cloud password is set well before the plan runs out.
FAQ
Can I use a free online SMS number to sign up for Telegram? It may get you through signup, but the number is public. Anyone watching the same page can request a login code for your account and take it over.
Does a second number make my Telegram account anonymous? No. It keeps your main number off the account, but your phone still sends its IMEI to the network.
Can I use a +888 number for WhatsApp or Signal too? No. Numbers bought on Fragment work only inside Telegram.
