Samsung Galaxy S5 got launched with different versions in almost all the continents.Depending on the network provider,phones are customized according to the network bandwidth.It's an error directly related to Wi-Fi calling in the android system.
Well the error "REG99-Unable to connect" is only seen on T-mobile network as it's a bit different from the international version.
Error REG99- Unable to connect
Problem faced by our blog readers :
I have been using WIFI calling since I got my Samsung galaxy S5 and for the most part it has worked like a charm. From past few days I have been getting a weird error "REG99 - Unable to connect" quite repeatedly which is a bit annoying. I've tried a few different WIFI networks from open network source to WEP security but nothing din't really work.
If I reboot the device then it normally connects, and stay connected for a while but eventually it comes back and creates the same issue again and again as a loop.
Disclaimer : So after going through the problem, I understood the glitch and came up with a solution which may work on your Samsung Galaxy S5.
- Volume Up key
- Home key
- Power key
