Collage of people reaching for each other while contained in smartphones.

When you get a new mobile phone plan, you actually have the option to keep your phone number.

For the inexperienced, it might sound like a difficult, technical process. But it's actually pretty straightforward in many cases. In fact, your new telco provider will do most of the work for you.

How to port your mobile phone number

Warning: make sure you don’t cancel your existing mobile plan before you receive confirmation that the porting was successful. If you do, you might not be able to get your old mobile phone number back. 

Also, you want to make sure that your existing number is actually under your name. If it isn’t, then you’ll need to fill out some paperwork and request a change of ownership.

  1. Compare and purchase a new mobile phone plan
  2. Activate your new mobile phone plan online 
  3. When asked if you would like to keep your existing number, say yes 
  4. Sit back and relax while your telco provider completes the process.


Is it free to port my mobile number?

Your current telco may charge you a fee to port your mobile number to a new provider. You’ll also need to pay any outstanding fees or balances owed before they agree to transfer your number across to your new mobile provider.

Can I use my old SIM card while porting?

Yes, you will still be able to send texts, make calls, and use your data while the porting process is going on. Once you receive a confirmation message that your mobile number has been transferred, you can start using your new SIM.

Will porting my number cancel my mobile service?

Your old mobile service will be cancelled once your number has been transferred to a new SIM or telco provider.

Can I port my number if it is disconnected?

Unfortunately, once your mobile number is disconnected, it’s gone. That’s why it’s important to make sure you don’t cancel your existing mobile plan before you receive confirmation that the porting was successful.
