Port my number - To TalkTalk Mobile

Your TalkTalk mobile SIM card needs to be active before you can transfer your existing number.

To activate your service, just call 2883 FREE from your TalkTalk mobile. Our secure automated activation process will ask you a personal question to identify you as the mobile service owner. This is free of charge and should be a quick call.

You can also activate your mobile service from a landline telephone. Call 0870 087 8751 to speak to an agent. Have your mobile number to hand as you will need this on the call.

Here are some of the most common questions about porting your mobile number to TalkTalk Mobile.


Do I need to do anything before I transfer my existing mobile number to my TalkTalk SIM?

If you are transferring your number from another network you'll need to request a Porting Authorisation Code (PAC) from them. If you have fulfilled your contract agreement with them they will give you this free of charge. Please note, if you are still within contract they may charge you to issue a PAC and end your contract early.

It's also a good idea to use up any calls and texts credit with your current network. You'll be able to enjoy our great rates and inclusive minutes, texts and data as soon as your number has been transferred.

What happens on the transfer date?

Your existing mobile number will be transferred to your TalkTalk SIM and will no longer work on your old SIM. You can then enjoy great value calls and texts using your current number on your TalkTalk SIM.

It doesn't take long to transfer your number but please be aware it can happen at any time on the transfer date. Please check your TalkTalk SIM regularly throughout the day to see if your service is active.

Please note: You may find on your transfer day that not all services will start to work at the same time. You may be able to make calls but not receive them until your port has fully completed on the day. You will also find your voicemail may take a little longer to activate. We recommend rebooting your phone (turn it off and back on again) following a number port. This will refresh all your services on the network.

Can I still use the TalkTalk mobile number once my number has been transferred?

What happens if I've already used part of my TalkTalk tariff allowance when I transfer my existing number?

If you have used part of your monthly allowance using the TalkTalk mobile number, the remainder of your monthly allowance will be available on your existing number once it has transferred.
