i have being using 2degrees for over a year now, the no signal happened two month ago, but go fixed after sim card swap.
i do have a phone from overseas but everything was working great, it's a m8 from Meizu.
now the 2degrees ppl are saying my phone is crap and their sim card is working fine with any other phone.
so upset by this!!!!! yes my phone is almost 4years old, but it works fine!
