How it works Request number transfer Number transfer rejected Number transfer within Simyo FAQ

How does number transfer work?

Are you switching to Simyo but want to keep your number? With mobile number portability, you can bring your existing number with you, for free. As soon as you submit your number transfer request, we’ll take care of the rest with your old provider.

What do I need for number transfer?

To successfully transfer your phone number, you only need:

  • Your phone number
  • A working SIM card for your current provider
  • A device where that SIM card works

Bringing a business number? Then we’ll also need your customer account number, which you usually find on your invoice, a bank statement, or in the customer portal of your current provider.

What happens to my old contract?

Once you’ve requested number transfer, we’ll cancel your old subscription or Prepaid for you. Your new subscription with us starts the moment your number has been successfully transferred. From then on, your bundles are active and you can use your new Simyo SIM card. That way, you avoid double costs.
