Ive just purchased a new mobile phone from tesco, its a Sony Ericsson W580i. Ive downloaded the nokiafree unlocking calc.
Ive entered the 15 digit IMEI code, calculated the unlock code and then entered it into the phone, but i just keep getting the message "network problem" and thats it.
Any help with this would be great.
**Title shoult read W580i**
