Sorry to hear that the handset has broken.
Truthfully, you're best bet is to get an unlocked handset as a handset locked to another network would not allow connections.
The only exception (which we can't guarantee in any way) would be Three UK locked phones.
This is because we use the same networks for coverage.
It's not a guarantee though and only a possibility.
To confirm, we don't recommend buying a locked device to use with our network.
