Thats the worst thing that can ever happen, imagine for example, Grab Drivers which are ferrying a customer to a new location which the driver doesn't know/ familiar with and just so happens wife/ kids calls and ask whats for dinner.

4G that drops to 2G for just that stupid call and sometimes is doesnt rebound to 4G and is stuck at 2G, how is the driver gonna navigate via their Turn by Turn Maps Guidance?

Should have a boycott of Celcom which still hasn't enable VoLTE for prepaid users/ legacy plan/ MVNO customers. Wanna do everything at the final moment, lazy asses. Should organize a mass port-out for Celcom customers

Edit: Android users can mitigate this temporarily by locking their devices at 4G mode, but without VoLTE, no calls can be received so they can ve reached via Voip based calls, iPhone users, out of luck.

what is the solution for those celcom mvno like redone? as of today, there is no news about volte from these mvno.

Well, 2022 is here and 3G/H+ is still broadcasting despite Celcom declare that it's 3G shutdown completed. In fact H+ can be use.

I think now got different issues. My colleague, which has VoLTE from DIGI told me now have issues calling between his family members, that are all on DIGI and VoLTE activated.

This 3G sunset Jendela tingkap thingy - does the gov know how many missed important calls are people experiencing currently? Last 2 weeks my son's teacher tried to call me several times to inform that my son is having a bad stomach ache, to no avail. Luckily, he still can reach my wife after that. But imagine how upset I am at this whole thing - voice calls, something that is basic, having issues in 2022. I'm not asking for 1gbps 5G or whatnot, please.
