I don’t know if this thread has been discussed before. I just want to know what is the max m2 should be use in p1i without any problem. So far I discovered the best max usage is 2g. I read some opinion saying that using 4g will slow the phone and phone usually restart and hang a lot. Currently im using 1g but I would like to extend my m2 to the limit without any harm to my phone. any advice?
