I have Yoodo and Digi numbers on grace period (inactive) and VoLTE still work on both lines without data.

Perhaps U Mobile is different.

Why do you want to turn-off VoLTE ?
Do you want to make a voice call over 2G ?

I keep saw many asking turn off VOLTE, no idea why many want to turn off
Does not affect anything or function of phone

Some phone owners begging for VoLTE pun tak ada...

.
Maybe, it's because some callers are still using non-VoLTE smartphones or have not activated VoLTE on their phones = these callers may not be able to call you via VoLTE.
.

No such thing, any volte and call to non volte phone
I tested when 3G shutdown, as my old device no volte, yes it fall back 2G

Funny that prepaid is a better deal than postpaid...

Why would anyone even use postpaid?

.
Afaik, VoLTE or Vo5G and IMS (not SMS) requires 4G/5G Mobile Internet data whereas 2G voice calls and SMS do not require such Mobile Internet data.

Some smartphone users who have Home Fiber Internet and VoIP fixed/immobile phone lines (eg 03- XXXXXXX for Selangor), subscribe to the cheapest prepaid Mobile phone plans and topup only (eg RM5 every 3 months) just to keep their Mobile phone line valid or active, in order to be able to receive voice calls or SMS via 2G. The VoLTE setting may interfere with the receiving of 2G voice calls.
....... Hence, these users often ask about maximum validity period given by the celcos.

Yes, during the 3G shutdown time (end 2022.?), my non-VoLTE phone on U Mobile received voice calls that were very broken = practically unusable, and many phone-users could not receive TACs or OTPs (which are 2G SMSes, not 4G IMS) from their banks or websites. IOW, at that time, the fallback to 2G was quite faulty. A few months later and nowadays, no more such voice-calling problems on my non-VoLTE phone.

umobile shut down 3g for few days only

network became basically unusable because 4g congested with calls and it kept dropping but umobile had nothing to fall back to

then umobile enabled 3g again, and now it is the best network in the country in terms of call quality

like before jendela only

volte calls can still switch to 3g network without dropping call when out of 4g network

only caveat is 3g network no internet for umobile since jendela

just for calls

you can set your phone to 3g only and use umobile extensive 3g network but for calls only

.
I doubt you are correct that U Mobile has re-enabled 3G, which is against government/MCMC orders, .......

.... Celcom and U Mobile have successfully collaborated through a commercial 2G domestic roaming nationwide agreement between period of 2007 to 2012, and 2019 to date.

https://technave.com/gadget/Malaysia-s-3G-n...%20March%202022. - Malaysia's 3G network shut down has been extended (from end 2021) to the end of March 2022 - 25 Feb 2022

https://myjendela.my/en-GB/FAQ-and-Glossary...g-Of-3G-Network - The Sunsetting Of 3G Network
1. What is the 3G Network sunsetting?

3G sunsetting is the gradual retirement of all the 3G network in Malaysia by mobile network operators (MNOs), namely Celcom Axiata Berhad (“Celcom”), Digi Telecommunications Sdn Bhd (“Digi”), Maxis Berhad (“Maxis”) and U Mobile Sdn Bhd (“U Mobile”) by December 2021. The completion of 3G network sunsetting will then enable the MNOs to provide faster and better 4G experience.
