What a virtual number is
A phone number that is not tied to a SIM card or a physical line. Calls and SMS reach you through an app, a web dashboard or a forwarded message.
The main types
Numbers can be shared or private, and rented for a set period rather than bought outright. Some receive SMS only, others handle both SMS and calls.
How SMS and calls work
Messages and calls are routed to your account, where you can read them in a dashboard, forward them to a Telegram chat or send them to a webhook.
How to choose one
Check that the number is accepted by the platform you plan to use, decide how long you need it, and confirm whether you need calls as well as SMS.

| Who can use it | Anyone with the same access | Only you during the rental |

| Calls | Often SMS only | SMS and calls |
| Duration | Minutes to hours | 28 days, with automatic renewal |

What is a virtual phone number?
It is a phone number delivered over the internet rather than through a physical SIM card. You use it to receive SMS and, in many cases, calls, without needing a separate handset.
Can I receive SMS with a virtual number?
Yes, most virtual numbers are built for receiving SMS. Whether a specific platform accepts the number depends on that platform, so check before you rent one.
Do virtual numbers work for calls as well?
Some do and some are SMS only. The numbers we recommend from SMS Activate App receive both SMS and calls.
How long can I keep a virtual number?
With SMS Activate App a number is rented for 28 days and renews automatically every 28 days while your balance covers it. You can switch renewal off at any time.
What should I check before renting a number?
Confirm that the number is accepted by the platform you plan to use, since the rental fee is non-refundable. Also decide whether you need calls, SMS forwarding or a particular country.
