Does my phone support eSIM?
Most recent iPhones, Samsung Galaxy S and Google Pixel models do. Check your phone’s settings for “Add eSIM” or “Mobile plan”; it also needs to be unlocked.
How to switch and keep your number
- Get your PAC. Text PAC to 65075 from your current phone. It’s free.
- Order your new SIM and give the PAC to the new network.
- Your number moves in one working day and your old plan closes.
On a 12-month plan? We’ll warn you before April.
Add your network and end date. We’ll email you before every price rise and three weeks before your plan ends, with cheaper SIMs already lined up.
