eSIM for Telegram: How to Register with a Separate Phone Number
Key takeaways
- SMS registration requires an eSIM plan with a mobile phone number and incoming SMS support. A data-only plan doesn’t provide a number for a separate account.
- You can add a second account in the official Telegram app and switch between accounts without logging out of your main one.
- Telegram chooses the verification method. The code may arrive by SMS or in an active Telegram session using the same number; email verification may also be required.
- Review phone number visibility, who can find you by number, and contact syncing settings in your new account.
- Keep access to the number after registration and check the renewal terms. You may need it to sign in again or recover your account.
You can use an eSIM with a mobile number to register for Telegram and create a second account. You need a separate number, access to verification and an internet connection. The eSIM connects a mobile line to your smartphone, while registration takes place in the Telegram app.
This can be useful for keeping work conversations separate, giving clients a dedicated profile or using an additional number while keeping your main one for personal contacts. Here is how to choose an eSIM, find your verification code and configure the account after registration.
Which eSIM is suitable for Telegram?
Choose a plan with a mobile phone number and incoming SMS. These features should be listed in the service description: “eSIM” alone does not mean that a plan includes a number for registration.
A data-only offer can provide internet access for the app. To create a separate account through ordinary mobile-number registration, you also need a number with an available verification method.
Ask the provider three questions before choosing a plan:
- Where will messages arrive: on your smartphone or in a separate interface?
- Will the line work in the country where you are now?
- How do you renew the service and keep the number for future sign-ins?
For an ongoing work account, consider the conditions over several months. Receiving the first code enables registration; keeping the number supports continued access.
How to set up an eSIM with a separate number
Revosim's eSIM with a US number includes a dedicated mobile number, incoming and outgoing SMS, and 100 MB of data per month. Messages arrive in your phone's messaging app. The plan costs $12.99 per month and does not support regular voice calls.
- Check eSIM support, carrier-lock status and coverage in your country.
- Connect to Wi-Fi and pay for the plan using your Revosim balance.
- Once the eSIM is ready, open it in your dashboard and select “Open installation details”.
- Add the profile using the QR code or manual details, enable the line and check the network connection.
The paid month starts when the eSIM, number and installation details are ready, regardless of when you install the profile.
Setting names depend on the phone. On iPhone, for example, you add a line in the cellular settings, with QR-code and manual installation options available. See Apple's eSIM setup instructions.
How to register Telegram with an eSIM: step by step
1. Prepare the app and connections
Use the current official Telegram app for Android or iPhone. In some scenarios, registration SMS is available only through official mobile apps, as explained in Telegram's authorization documentation.
For registration, you need internet access for Telegram and a working mobile line for SMS. You can use Wi-Fi or your primary SIM for internet access while keeping the additional eSIM for messages.
2. Start registration or add an account
If Telegram is not set up yet, begin registration from the welcome screen. If your personal account is already open, find “Add Account” in the account menu or profile settings. Its location depends on your platform and app version.
Telegram supports multiple accounts in one app on Android and iOS. You can switch between them without logging out of your main profile, as described in the official Telegram blog.
Choose the add-account option for an additional profile. Changing a number updates an existing account and serves a different purpose.
3. Enter your separate phone number
Enter the number in international format. The country code for a US number is +1. If the app inserts it after you select the country, enter the rest of the number without repeating the code.
The country in this field refers to the number, rather than your current location. Compare the full number on screen with the details of your connected line before continuing.
4. Complete verification
Check which code-delivery method the app displays. For SMS verification, open your smartphone's messaging app, find the Telegram message and enter the code.
If you have previously signed in to Telegram with this same number on another device, the code may arrive in that active session, in the Telegram service chat. An open personal account on a different number is not such a session.
The system selects the delivery method. If the app asks you to verify an email address or complete another step, follow the on-screen instructions. Having an eSIM does not let you choose any verification method in advance.
5. Set up your new profile
After verification, provide the information requested by the app. For a work account, choose a clear name and a recognizable profile picture so clients can distinguish it from your personal profile.
Check which account is selected before sending a message. Notifications may arrive from several profiles; adjust them so work conversations fit around your personal use.
How to configure privacy for your separate account
A second number helps organize conversations, but you should review visibility settings separately. Open “Settings” → “Privacy and Security” → “Phone Number” and choose suitable rules for showing your number and allowing people to find you by it.
Telegram lets you communicate without displaying your number to other users. However, someone who already knows your number and has saved it in their contacts may see it, as noted in the Telegram FAQ.
If you want to build your work contact list yourself, pay attention to the request for contact access. You can stop syncing contacts and delete previously synced contacts in the settings. These options are described in Telegram's privacy policy.
Consider your name, photo and username as well. They help people recognize the profile, so a separate number does not make an account anonymous by itself. For work conversations, choose a username that is easy to share on a website or business card.
What to do if your Telegram verification code does not arrive
Start with the message on the verification screen. A missing SMS does not always indicate a line problem: the app may be waiting for a code from another session or require a different step.
| Situation | What to check |
|---|---|
| The code was sent through Telegram | Check the service chat in an active session for the account with this number |
| The code was sent by SMS | Verify the number, the line's network connection and the plan's active status |
| A timer is displayed | Wait until another request is available and use the method offered in the app |
| The app requests an email address | Complete that step and check the specified inbox |
| A password is requested | It may be the two-step verification password, rather than an SMS code |
If you do not recognize the password and have not created an account with this number, clarify the situation with your number provider and Telegram support before continuing.
In some scenarios, Telegram may require a Premium subscription to continue registration or login because of SMS costs for the relevant carrier or the number's country. This is a Telegram requirement; paying for an eSIM plan does not replace it.
If regular SMS works but the Telegram code does not arrive, contact Telegram support. For problems with the line itself, give Revosim your phone model, country and a description of the issue.
A plan without voice calls cannot receive verification through a regular phone call. Check the methods offered by the app and supported by your line.
How to keep access after registration
After creating the account, open the privacy settings and enable two-step verification: set a separate password and add a recovery email address. Do not share registration codes with other people.
You can also create a passkey. It lets you sign in with your device PIN or biometrics instead of SMS. Set it up under “Privacy and Security” in the “Passkeys” section. See Telegram's official announcement.
Even with a passkey, Telegram recommends keeping an active number under your control. This is especially relevant when changing phones or reinstalling the app.
Monitor eSIM renewal: you may lose the number without payment. With Revosim, data stops after you use 100 MB, and SMS may also pause. Use Wi-Fi or your primary SIM's data for conversations.
When to change your number instead of creating a second account
If you want to move your existing profile to a new number and keep your cloud chats, use “Change Number”. In Telegram, you can find it in account settings after tapping your current number.
If your goal is separate work conversations, create an additional account. Before taking action, decide what you want to keep: one profile on a new number or two independent profiles for different purposes.
Frequently asked questions
Can I register Telegram using an eSIM with a US number?
Yes, if Telegram accepts the number and you can complete an available verification method. Outside the US, also check coverage and SMS-delivery restrictions.
Do I need a second smartphone for another account?
You can add accounts in one Telegram app. The eSIM itself needs a compatible phone; the ability to keep multiple mobile lines active at once depends on the device.
Will Telegram work over Wi-Fi?
Yes. The app can use Wi-Fi even if the account was registered with an additional eSIM's number. Keep access to the number for continued account use.
If you need a separate mobile number on your smartphone, review the conditions for Revosim's eSIM with a US number. Check device compatibility, coverage and renewal before buying: these matter for registration and ongoing Telegram use.
Check current pricing, coverage and available features on the plan page before connecting. Telegram determines the verification methods; having a number and SMS support does not guarantee completion of every check.
