Our network and the Orange network now work together better than ever.
Your smartphone will automatically check to see which network has better coverage and switch you over without you even noticing.
When you're using the Orange network, your phone thinks you're roaming outside the UK, and might warn you about charges.
Don't worry, you will only pay UK charges while you're using your phone in the UK.
If you use the Orange network, nothing else will change about your account.
You will still be a T-Mobile customer and you will be charged just the same, whether you're on T-Mobile or Orange.
We're laying the foundations for a new digital Britain. See more about the investment we're making in our network
