Activating TalkTalk Mobile
Simply insert your TalkTalk SIM card into your mobile and switch it on.
The easiest way to activate your service is online in My Account. Just select the Activate my SIM option and away you go. If you're transferring your mobile number over to us you'll be given the option to enter your PAC (Porting Authorisation Code) and existing number. Please see Port my number - to TalkTalk Mobile for more information.
If you don't have access to the internet you can call 2883 from your mobile to activate your service. However, you'll still need to go online later if you want to transfer your existing number. Make sure you have both your Bank Account details and the new TalkTalk mobile number handy (this is for security reasons). Our secure automated activation process will ask you to enter the last 4 digits of your Direct Debit account number. This is the bank account you are using to pay your monthly TalkTalk Mobile bills.
For example: If your bank details were Sort code (11-22-33) and Account number (01234444). You would need to enter 4444 in order to complete the activation process.
This is free of charge and should be a quick call.
Your line rental charge will start on the day you activate your SIM card. Or, 9 days after we dispatch your order, even if it's inactive. We recommend you call us and activate your SIM card as soon as you receive it. You should never activate a SIM card before you have received it. If you have not received your mobile or SIM card, please see where is my mobile or SIM order?
Set your phone up for all the services you want to use like Wi-Fi, voicemail, mobile internet/photo messaging and email. See our simple step-by-step instructions in Mobile and Tablet Setup guides for more information.
