My daughter keeps wrecking smartphones and so we got her a Motorola Defy+(PAYG). It was bought new and unlocked with the French Retail ROM and once i put in the SIM(O2-UK) and tried to top-up her credit(4444) it would not dial out and did not give any problem message. I also tried to ring her number from my phone which came up with "it has not been possible to connect your call - please try again later" message.
I did a hard reset and got the same problem so I downloaded the latest UK Retail ROM from XDA(this went on no problem) and tried again - Same problem. The box states it is for use in EU & UK/IE so this cannot be a problem.
I have the correct APN settings and have tried 2 other O2 SIMs but still the same problem exists??!!
The only thing i think it could be is a hardware fault and i need to send the phone back.
Everything else works fine WiFi, GPS etc etc.
Apologies for the long winded explanation but i thought you would get more responses this way
Any assistance would be of utmost value as im stuck with a daughter needing her mobile like yesterday!!
