I have an unlocked Motorola Defy which I used to use on the Orange network in the UK. We have purchased crazy johns phones for the free texts and calls to each other, and a sim card for my Defy. The problem is I cannot get any signal ( 'no service' message displayed on phone) on my UK phone.
Have tried an Aus virgin sim from another phone and it worked OK. Have also tried old o2 sim from UK and it worked so I am sure the phone isn't locked.
Is there a problem with compatibility with some local network providers and UK phones??
Any answers would be greatly appreciated as I am the only family member without a working phone at the moment.
