There is a option on ur mobile network setting to enable 2g ...
It sounds like you need to set the APN for your carrier.

On the AT&T version the necessary menu is not enabled. Check this thread where someone asked the exact same question a week ago and I posted how to enable it.

Hello Everyone,
I have encountered a problem with my samsung galaxy s6 edge, i bought this phone from ebay, and i am using this phone in sweden with my halebop(telia) network. Problem is when i am in coverage area of 4G my phone will show the signal and will be have full coverage and everything works perfectly, but when i am in area where there is only 3g, my 3g works but there is no coverage on my phone, i tried to do it manually assiging the network in 2g/3g auto mode it says network registered but still no network on my phone. Before buying i even checked the history of the phone, it was not black listed and not stolen nothing. Moreover if i use my sim of Pakistan or sim of Dubai it works perfectly even shifts to network (if i chose 2G/3G auto or 2G only ) it works fine but don't work with my sim.
Can anyone please guide me because i am searching it internet but couldn't find anything. I also order new unlock code and even after inserting the code phone says unlock successful but still problem of the coverage.

i have a similar problem i have it set on lte/wcda/gsm autoconnect but once i go to my basement i get little to no service which means the phone does not switch to gsm i also tried it on a friends edge and got the same result maybe this is a carrier issue (zong pakistan)..i have searched and also posted here but to no avail i am left with only one option which is to switch it to gsm mode whenever i am in my basement.

try this code in your dialer *#2263# and switch your network to gsm only to see if it works

Is your network provider a 4G network?
Like in the UK EE network is 4G only, therefore if i try to switch to 2G it will not get signal.
Maybe custom ROM can solve this? HM?
sorry for digging an old thread.
I have the same problem but reversed. My s6 edge can detect 3g 4g network but connects to 2g only. otherwise it has no service.
i bought it from UAE. it was working fine there. but now in Pakistan it connects to 2g only.
if i switch to 3g only or LTE/3G/2G auto then it doesnt connect to network. i can manually search for networks in that mode bit cannot register to network.
In 2G only mode, it works fine.
Hello developers.
I am amz. In dire need of your help.
Ok so i have a new mini
I turned it on n it would jus turn off if I used apps. I got a new battery. That stopped.
I then try use Internet it works only on G and E but if I go to 3g or Lte. .H will never come on. Can't call it says not registered on network only on the higher bands not gsm.. It's a 4G sim it works perfectly in my old s5 mini and signal is excellent here. I got new Internet settings too. G n E works why the he'll doesny the other bands register on network? Imei shows its not blocked either. I'm in the UK on EE. I cannot understand. I have all the OTA updates. Can u tell me if I can fix it by doing something thro service menus or anything also all sims do the same in this phone. I don't have a pc to change the rom. Could I do it through a external SD card.
Please I beg of you help.
