I have the S2 Galaxy with ICS 4.0.3 - carphone warehouse version , it was originally locked to UK Orange.
On Orange it always allowed phone calls to be made whilst the phone internet data was also turned on. (H+ in the top right corner)
Now that I've had the phone unlocked and am using a UK 3 sim card, I've had problems with the phone use.
1) If the internet data is turned on and I'm not browsing and I try to make a phone call - I get the message - 'No internet calls allowed' ??
2) On trying to access the phones data internet I now keep getting a web message from 3 - 'Your trying to use your phone as a modem or in a hotspot' ??
I've toggled between the data packet selection and the data roaming selection buttons in the wireless and network settings area.
Phoned 3 a few times, been through all the checks in the settings area.
Anything that shouldn't be checked isn't!
Anyway I've been directed to the APN settings and there is nothing there - everything is UNSET !
I've read the threads here and used the 3 APN settings and my phone will not save what I type in?
3 went through the set up and to finalise I pressed save - only for it not to save - the APN page is still blank.
Any ideas on what the problem could be ?
