Just got a replacement for my old phone which is exactly the same - z3 compact - but with this one the mobile data is not working. I've downloaded the internet and mms settings multiple times and even entered the apn data manually but it just won't connect over mobile. I've had the settings sent to my phone using the virgin mobile service too where you have to enter the pin and select the phone. There's no problem connecting to the internet via the wifi connection and the network is working for phone and texts, obviously mobile data is turned on, I've even tried turning data roaming on but that makes no difference. Can someone help?
