I have 2 smartphones. Both on different telco.

My main smartphone is a newer Samsung phone that support 5G and VoLTE. Another smartphone is an old Android smartphone which I currently use as secondary or backup phone only, and seldom use.

The backup phone was purchased about 9 years ago. All functions still working perfectly. It support 4G. Just one problem, it does not support VoLTE. This mean, when making or receiving calls, it will switch to 2G network.

The backup phone, I seldom use it. It is using the older UniFi prepaid plan, which currently still active.

A few months ago, on my backup phone, the call still working, even though it will switch from 4G to 2G network. But, today, I tried to make some usages to keep the prepaid plan active. 4G internet still working. I noticed that I cannot make any call. So, I try to manually switch the phone network from 4G to 2G. I noticed that there is no 2G signal at all. That is why I cannot make call, since the phone not support VoLTE.

Is UniFi mobile not support 2G anymore?

If yes, then I need to either upgrade my backup phone, or switch telco.

Unifi started as P1, from the beginning as 4G only company. They never have 2G spectrum license before. Better buy new phone.

But, a few months ago, the 2G network still working.

Then might be spectrum sharing deal finished or something. In any case, matter of time before all 2G will shutdown too. 3G already shutdown, to give more room for 4G and 5G. Might as well buy new phone now, even used 2-3 year old android is good enough.

last time 2G roaming on celcom. after become celcom digi no more roaming.

unifi mobile has RAN share with Maxis for 4G & 2G so it should still work but do bear in mind that 2G networks are not exactly that optimised as everyone s more focused on 4G & especially 5G now...
i am usin unifi mobile also n i just tested n managed to connect to 2.5G (EDGE) at TRX area now...

Still got ma, just tried just now. Roam with maxis

try the unifi sim on your samsung phone, turn off 5g, turn off volte, test 2g call?

I just tried my unifi mobile 2g, confirm working. So it's ur phone issue.

After office hours, after I leave my workplace and then went to certain area, I found that 2G signal is full. So, I guess that may be some 2G cell stations near my workplace are down.
