Searching cellular network, but full bars.

[brian1984]

Hi, I'm using the Galaxy S5 from T-mobile for almost a year, but on the last 3 days for some reason when I go to a place that I lose signal and come back to the outside my phone doesn't connect back to T-mobile and keeps "searching".
The strange thing of this is that even if it says Searching where suposed to say T-MOBILE, I get full bars and 4G connectivity.
I can go to any website, or do whatever I want that goes through data, but when I try to place a phone call or send SMS phone tells me that is not connected to a network. I have to turn off and on my phone in order to be able to make phone call again.
I did hard reset and problem still happening.
did anyone had this problem before?

I don't have an answer to your problem, but just a suggestion. Most likely toggling airplane mode on/off will restore your connectivity much more quickly than a full reboot, try that next time.
A call to T-Mobile customer service might be in order, they might be able to do something if it's on the network side.
