So i just got my second windows phone (nokia lumia 710) and because its cheaper and easier, i like to use IM instead of SMS (I use SMS when i'm out, and IM when i'm home, which is the most of the time). But i've soon realised that after about a minute of the screen being locked, the wifi disconnects, and only reconnects when i unlock the phone. This is really frustrating because it means that messages aren't pushed to me when the phone is locked. and it also means that i appear offline to the other person, so they don't message me back. I understand that this is a windows phone 'feature' to save power, but does anyone know if it can be turned off?? that would be so useful
My first windows phone never did the same, but it ran the same version (mango)
And I know that getting a data plan or just using SMS will fix this all, but im 16 and tight on money as it is, so i would like to stay away from spending extra money every month
Thankyou for any help
