Do you have the latest software update for the phone?Having what sounds like exactly the same issue. GOMO sim in Nokia 2.4. But there is no option to disable VoLTE anywhere in my options...
What the make and model of the phone?Seeing a similar issue with a 48 sim at the moment. Works in an older phone, but not in a new replacement phone. Other SIMs wotk in the new phone, although 48 support (I use that term with tongue in cheek) inisist it is the phone that is the issue.
Their network is not showing up when I search.If you do a manual network scan can you see and connect to 48?
I don't understand what that means.I suspect it's initial location for this set up.
So the SIM did work in your phone at some stage?I'm rurally located, but up in the big smoke last night and response was much more positive (a bit patchy in places) -

Does dialling *#*#4636#*#* and pressing the "call" button give you any option to disable VoLTE?
Can you try the SIM in another unlocked phone?
Have you contacted Gomo? Did you just move to them?
Ok, you might want to see if there's any Samsung forum/support that can tell you if/how VoLTE can be switched off on that phone.Yes latest software updated. This has been ongoing for months now. It wasnt originally an issue with phone, so I think a system update introduced voLTE and caused this. To be honest I had given up until coming across this post. I havent tried the sim in another phone but the similarities with 1dave123 description make me think its the same issue.
Can't see any image.ClubMan I tried this code. I dont see an obvious option for turning off voLTE. allows setting various network types but I wouldnt know which to choose. see image
