Ok so i have had my note 2 for over a month now and it has been nothing but frustrating. Initially when i got it, tmobile was doing work in my area and the coverage was horrible for about 2 weeks. Standing in front of the tower i couldnt even stay on edge. During this time i experienced several problems...
My phone will not ring when people call it, nor will it receive texts. Only upon actively using the phone will Voicemails and texts push through. Anything data related comes in fine. The missed call notification also does not show, so if they dont leave a voicemail i have no idea i have been called. The coverage problem subsided and me and several friends have great 4g speeds in our area now. So i assumed this problem was related and was fixed.
This problem persists despite having full bars or connected to WiFi with wifi calling on. I have no idea what to possibly do that i havent. This happens at all different times of the day and the time of inactivity could be 5 minutes or 5 hours before it misses a call. I have literally used my phone and then 5 minutes later someone tells me they couldnt call me.
Stuff i have done:
Factory reset (twice)
SIM reset (several times)
WiFi Calling (Used both router bands and different security - WiFi Sleep settings checked to ensure it doesnt drop)
Used Wakelock apps to keep the CPU and wifi connected from going to sleep
Called Tmobile several times and they did what they could from their end
My house has 3 phones, one being ANOTHER note 2 with no problems and a vibrant. I also came from a vibrant and never had these problems.
My only two options i have left to try it seems is, replacing the SIM card or replacing the phone. Both of which all i ever read is that this does nothing to change the problem. Hopefully someone can post with either a success story or some useful info and not the usual checklist of things i have done.
