I have a samsung galaxy s4, i have a lot of problems in general with o2 data signal. Can anyone let me know why we lose data sgnal whilst on a phone call. Other networks dont have a problem they can multi task whilst on a phone call but with o2 you cant do that because when you are on a phone call, the data signal disappears, so iyou cant check mail, get whatsapp messages etc.
Is this a network problem or a settings problem??
On 2G you get either data or calls, not both
On 3G you get data AND calls and works fine for me on O2
On 4G you get data only
It's possible that you are on a fringe coverage area and the phone is dropping to 2G whilst on a call which would point to a network rather than phone issue?
