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.
2) Contact giffgaff to cancel your contract and get a PAC Code
With your phone wending its way to you, you’ll now need to contact giffgaff to tell them you’d like to leave and get a PAC Code. A PAC is a short, alphanumeric code, which is critical for transferring your number to the network you’re joining.
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 on SMARTY
Assuming you’re out of contract, your next step is to sign up for the SIM-only deal you’ve selected on SMARTY. You’ll receive your SIM card in the post after you’ve passed SMARTY's credit checks.
4) Contact SMARTY to give them your PAC code
Not much longer to go now. Your next task is to get in touch with SMARTY to give them your PAC.
Because SMARTY doesn't have a customer support telephone contact number, you're required to log in to your SMARTY account and submit the PAC Code that way. You can do that right here.
5) Take out your SMARTY SIM and put it in your phone
Got your phone to hand? Okay, you now need to unlock the SIM tray using a pin or the key that came with your phone. Once it's open, insert your SMARTY SIM in your handset.
Your number won't be transferred instantly. But you will have a temporary phone number to use while the process is underway. So you'll still be able to use your phone and you'll be contactable.
6) Wait for your number to be transferred to SMARTY
SMARTY advises that the process of transferring your number will take up to two working days. The transfer usually happens between the hours of 11am and 5pm.
In the event that the transfer doesn't seem to have worked, try turning off your phone and then turning it on again.
If there's still a problem, get in touch with SMARTY via webchat service on its site.
