[Q] problem with GSM network

i notice that my phone have problem of losing connections (phone signal) quite often which causes the phone cant make or receive call. i usually go outstations and everytime when i travel i have this problem. i thought it was the problem from the android 1.6 but after updating to android 2.1 through the SE website the problem is still there. recently i end up with the conclusion that my phone have problem with GSM signal, whenever i go to outstation where there is no 3g/WCDMA in the area but suppose to have the GSM signal i got this problem. please bear in mind that i have change and tried the setting for WCDMA ONLY,GSM ONLY & WCDMA/GSM PREFERED but the problem still persist, and please bear in mind i have tested with my other phone and it works fine at those places. please advise if this is the problem of the phone itself or just the setting of my phone.

H+ full but no Internet Connections - Handover problem ...

Hello friends ...
I've got a big problem, and this since few different devices and ROM's ...
as soon as i'm in a area where a lot of differend mobile cell's crossing, my mobile data stucks at full H+ signal!
It means, phone is in a H+ cell, but seems if it can't get a stable connection!
I contacted already my provider, they told me, it could be cause of the "handover", the phone is switching between different cell's!
I've been looking at this problem about two years and a lot of different phones, and its only on android phones!
I switched already the Sim cards and anyways, i have it on both networks, privat and business!
So now, i couldn't find any solution!
Maybe one of you guys have any ideas? Any app or xposed to avoid the handover?
Thx mates!
Ps: current i'm on OnePlus 3 with CM
Hmm ... no one any ideas?
