Hi I have a samsung s9 and pay as u go but it's coming up enable to connect to my we network everything else working but can't make calls says no nstwork
That's likely due to either
- phone not activated
- phone IMEI flagged as lost/stolen and blocked (blacklisted) at network level (check with provider or pay for a check on https://checkmend.com)
- problem with SIM
- cancelled SIM or account (check with service provider!)
If you bought the phone second hand and it's a grey import, you'll need to activate it with a SIM card from a territory which the phone is intended for. All Samsung phones are region locked. See this thread for more info:
I have the s9+ with the same problem of not connecting to mobile data when leaving a wifi area.... there is no ability on the phone to turn the volte on or off on this phone so why does everyone keep referring to it. I've had 3 phones replaced and I still have the problem....
If your firmware & device supports VoLTE, you'll find it here (Android Pie, One UI):
swipe down from top of screen -> cog menu -> Connections -> Mobile Networks -> "VoLTE calls SIM 1 enable/disable"
Phone dialer -> three dot menu in top-right corner -> Settings
If you can't see it, VoLTE isn't available as an option either due to your provider restricting the feature or it not being available on your particular hardware revision. Don't ask me why it's not universally available, I think it's as stupid as you do
Disable Wi-Fi Calling and see if your mobile data starts working when leaving a wifi network. If it does, check you have the latest monthly update, as this was an issue for me and other S9 users until Samsung pushed out a patch with the February 2019 update.
Thanks for your answers but obviously I don't have Volte settings on my phone and not sure if Samsung just incoporated it into there software so you can't turn it on or off as suggested. Only once did I see an Volte setting up in the connection area so it must be there. As far as turning the wifi off when leaving my home wifi, the phone will connect then to 4g but again once I go back inside I would have to go through the process of turning wifi back on. Obviously, this is what I'm trying to get away from. Wife has an S5 Samsung it works perfectly fine going from wifi to 4g and back. So far Samsung and AT&T again are of no help and on my 3rd replacement phone. All software is up to date.
