Swapping mobile phone operators can seem a little daunting, especially if you’ve been with the same network operator for a while.
In fact, moving mobile phone provider is incredibly easy. If you don’t move you could be missing out on some brilliant deals for BT broadband customers, such as BT Mobile’s £7.50 a month plan, which includes unlimited minutes and texts.*
We’ve got answers to your common questions.
If I move to BT Mobile can I keep my current number?
Yes, but first you’ll need to call up your current mobile provider and ask for a PAC code. They are legally obliged to give this to you within two hours.
PAC stands for ‘Porting Authorisation Code’. This nine-digit code is valid for 30 days and is a method used across the mobile phone industry to make sure no-one else gets your number.
Once you get it, head to bt.com/keepmynumber and log in using your BT ID.
Will I be without a working phone during the move to BT Mobile?
It takes around 24-48 hours to move your number. If you give BT Mobile your number before 4pm on Monday it will be moved on Tuesday; if it’s after 4pm on Monday, it will be moved on Wednesday.
Until the move is completed you can still use your old SIM.
Put the SIM cards in your phone and they will both work, but calls to the number which is being moved will go to your old provider’s SIM until the move is complete.
Do I need to unlock my phone to move to BT Mobile?
If you are moving to a BT Mobile SIM-only plan and bought your phone from another mobile network it may be locked, so it will only work with SIM cards from that network.
To unlock your phone you’ll need to contact your old provider: many have online forms you can fill in, which makes it a very easy process. Use the following links: EE/Orange/T-Mobile, O2, Three, and Vodafone.
Make sure you have the details of your phone to hand, such as the make/model and IMEI number, which you get by dialling: *#06#
To find out if your phone is locked, try putting your BT Mobile SIM in and turn it off and on, if you can’t see the BT logo your phone is probably locked.
We suggest you try this first if possible and if you think your phone is locked, get it unlocked before you complete your move to BT Mobile so you aren’t without service.
Will my BT Mobile SIM card fit?
SIM cards come in standard, micro and nano sizes.
If you want to keep your existing phone and get a SIM-only plan with BT Mobile you’ll need to make sure you use the right size of SIM.
BT Mobile sends customers triple SIM cards, which include standard, micro and nano SIMs, so simply insert the correct one for your phone.
If you lose your SIM or it’s damaged you can order a new one at www.bt.com/replacesim
How do I know when I’ve swapped from my old provider to BT Mobile?
The move can happen any time between 11am-6pm.
BT Mobile will send you a text to let you know the move has been completed.
When you get the message, take your old SIM out and put your BT Mobile SIM in your phone; all calls to and from your number will then be on BT Mobile.
Later that day your service with your old provider will finish.
How can I save my contacts and photos?
