1) Check you’re eligible to switch from giffgaff
Assuming you’re out of contract, it won’t cost you anything to leave giffgaff. If you’re not sure whether you’re still under contract or want to find out your contract end date, you’ve got a few options.
The first is to log in to your account at giffgaff’s site.
The second is to log in to the giffgaff app on your phone.
As you’ll almost certainly know, giffgaff doesn’t operate a telephone customer support service. So you won’t be able to get in touch over the phone.
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact giffgaff to cancel your contract and get a PAC Code
With your phone wending its way to you, just text PAC to 65075 to get your PAC code. It’s this short, alphanumeric code that will enable you to transfer your existing phone number to the network you want to join.
Alternatively, you can get your PAC code from giffgaff by logging into your account online and requesting one.
Or you can get one by texting 43431 from your giffgaff phone.
All networks are obliged to supply your PAC within two hours of your request. Once you’ve got it, you may want to make a note of it. Just in case.
PAC Codes are valid for 30 days only. If you haven’t used yours within this timeframe, you’ll need to submit a request to giffgaff for a new one.
3) Find and buy a deal from Tesco Mobile
Assuming you’re ready to switch, it’s time to select a deal from Tesco Mobile and sign up for it through Uswitch.
Tesco Mobile will, of course, conduct credit checks. But assuming you pass, you’ll then receive your phone in the post.
4) Contact Tesco Mobile to give them your PAC Code
Now you’ll need to contact Tesco Mobile and give them your PAC Code.
You can get in touch with Tesco Mobile’s customer support team on 0345 301 4455 (standard network rates apply).
Opening hours are 8am-9pm Monday-Friday. 8am-8pm Saturdays and 10am-6pm Sundays.
5) Insert your Tesco Mobile SIM
Okay, now it’s time to insert your Tesco Mobile SIM in your new phone, or in your existing phone if you bought a SIM-only deal.
You’ll find that the number won’t have transferred straightaway. But while the transfer’s underway, you’ll be given a temporary number. So you’ll still be able to use your phone.
6) Wait for your number to be transferred to Tesco Mobile
All being well and if a weekend doesn't get in the way, your number should be transferred the next working day. After which point, you’re good to go.
