Even I am facing the same order on my tab but in a different way. I can recieve signal for the carrier Tata Docomo but other carrier are showing any sign of life
But sometimes while on tata docomo , I lost signals while using data or when I got a call. And one more thing, I was on a trip to a hill station and there I was getting signals from Vodafone perfectly (my main service provider). But when I came back from there I ain't receiving any peice of signals from vodafone and Docomo is working as usual with few network losses during the day.
PS.- I ain't received any solution yet, still sticking up with that problem.
PPS.- The tab I brought is in used condition with the fact that the tab has that problem in it.
(I need not to pay much lol)
Btw I think if we can flash new firmware (official) with odin with modem file, It may sokve our problem. TRY FLASHING FIRMWARE, I cant as I am low on speed
, If I helped you in some way other wise keep
