1) Check you’re eligible to switch from BT Mobile
If you’re out of contract you can switch from BT Mobile when you like and it won’t cost you anything to leave.
If you’re not sure if you’re still under contract, you can find out in a number of ways.
One option is to contact BT Mobile customer support on 150 from your mobile phone. Or by calling 0800 800 150 from any other phone (standard network rates apply).
Opening hours are 8am-8pm Monday-Friday and 9am-6pm Saturday and Sunday.
Alternatively, you can find your contract end date by opening the BT Mobile app on your phone. Or by logging in to your BT Mobile account.
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact BT Mobile to tell them you want to leave and get a PAC Code
Now’s the time to contact BT Mobile to tell them you’d like to leave. To do this, 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.
If you'd prefer to speak to someone, just give BT Mobile a call. You'll find contact numbers and opening hours for customer support in step 1.
It’s a legal requirement that networks provide you with your PAC Code within two hours of your request. When you’ve got it, it’s clever to make a note of it. Just in case.
What’s most important to note, though, is that PAC Codes expire after 30 days. So if you haven’t used yours within this timeframe, you’ll need to get in touch with BT Mobile again to request 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.
