What can't I do with a rental number?

NorthSMS rental numbers are built specifically to receive incoming SMS — for example verification codes from WhatsApp, Telegram, and similar services. Receiving the code is enough to complete verification, but this focus also defines their limits:

• No phone calls. Rental numbers cannot make or receive calls.
• No outgoing SMS. You can receive messages, but you cannot reply or send messages to anyone.
• Capabilities can vary per number. If you have a specific requirement, check the details shown for a number before renting it.

One more important limitation: if a service has already been used ("burned") on a specific number, that same service cannot be verified again on that number. In that case, rent a different number for the service you want to verify.

If you need a number for calls or general two-way communication, that is outside what rental numbers are for.
