Transfer A Phone Number From Tesco Mobile to TalkTalk Mobile: Step-By-Step Instructions

Switching from Tesco Mobile to TalkTalk Mobile? It's a straightforward process to keep your existing phone number.

Step 1: Get a PAC Code from Tesco Mobile

If you’d like to move your phone number from Tesco Mobile to TalkTalk Mobile, the first step is getting your Porting Authorisation Code (or PAC Code) from Tesco Mobile.

There are three ways to get a PAC Code from Tesco Mobile:

1. Online: You can get a PAC Code from Tesco Mobile by logging in to the Tesco Mobile account website. Once you've logged in, go to Request a PAC.
2. By Text Message: You can get a Tesco Mobile PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from Tesco Mobile.
3. By Phone: You can get a PAC Code by calling Tesco Mobile. To do this, call them on 4455 using your Tesco Mobile handset. Alternatively, dial 0345 301 4455 from any other phone. You'll need to call during Tesco Mobile's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 10am-6pm).

Here are some key things to know:

• The PAC Code from Tesco Mobile should consist of six numbers with TSC at the start (e.g. TSC 123 456).
• Your PAC Code is valid for 30 days. If you don't use it during this time, the PAC Code will expire and you'll need to request a new one.
• You shouldn't close your account at Tesco Mobile: it'll be closed automatically when your phone number is transferred to TalkTalk Mobile.

Still in contract with Tesco Mobile? If so, you may need to pay an early exit fee on your bill from Tesco Mobile. To find out how much this would be, text INFO to 85075.

Don’t want to keep your Tesco Mobile phone number? You can switch to TalkTalk Mobile without taking your phone number with you. If you'd like to do this, get a STAC Code from Tesco Mobile instead.

Step 2: Order your new phone or SIM card from TalkTalk Mobile's website

You should now order your new phone or SIM card using the TalkTalk Mobile website. Please select the type of tariff you're intending to move to:

• Pay Monthly
• SIM Only

For a full list of available tariffs and the latest TalkTalk Mobile deals, please refer to this page on TalkTalk Mobile's website.

TalkTalk Mobile will assign you with a temporary phone number during the transition process. This will allow you to test out the service before you finally transfer your phone number to TalkTalk Mobile.

Step 3: Give the PAC Code to TalkTalk Mobile

Once your new phone or SIM card arrives from TalkTalk Mobile, switch it on and make sure everything's working properly. If, for whatever reason, you need to return or change the handset or SIM card, it's best to do this before transferring your phone number.

Once you're happy to continue with the phone number transfer, contact TalkTalk Mobile and provide them with your PAC Code from Tesco Mobile.

You can give the PAC Code to TalkTalk Mobile by calling 2883 on your TalkTalk Mobile handset. You can also call 0345 172 0044 from any other phone.

If you have a STAC Code from Tesco Mobile rather than a PAC Code, this can be provided to TalkTalk Mobile in the exact same way.

Remember:

• You must provide the PAC Code to TalkTalk Mobile within 30 days of it being issued by Tesco Mobile. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from Tesco Mobile.
• Tesco Mobile Pay As You Go customers: Try to use up your remaining credit as it can't be transferred to TalkTalk Mobile.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to TalkTalk Mobile before 4pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 4pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on TalkTalk Mobile. You should find that the TalkTalk Mobile phone or SIM card will now associated with your original phone number.

• If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
• Once the phone number has been transferred to TalkTalk Mobile, your account on Tesco Mobile will automatically be closed. You'll receive a final bill from Tesco Mobile for any outstanding charges.
