How to switch your mobile
With our SIM only offers, you can bring your own phone, manage your spend and get the BT Sport Pack on your 4G phone.
Order your BT Mobile plan today and ask your current mobile phone provider for your PAC code.
Once you’ve received your SIM card, activate your new BT Mobile SIM (your welcome pack, sent in the post will explain how).
Tell us what your PAC code is, and we’ll transfer your number to your new phone. This should take about 2 days.
Your SIM card will arrive within 1-2 business days. See packages
