All telcos will do that once they have the "confidence" that the cell tower(s) in that zone is "tested" "thoroughly".

In deed...

Please rest assure (very standard and scripted reply by Customer Service ... LOL...) that those 3G cell towers have been "re-farmed" into 4G spectrum(s). Therefore, if the location that U visited "was" connected to 3G before; soon, starting from 1st January 2022 onwards, the device will connect to LTE spectrum(s).

Please ensure the SIM that is receiving calls must be placed in SIM 1 slot.

Depends on the modem inside the devices. Some modems support dual-LTE Active connections. If this is the case, both slots will support LTE and VoLTE. Some modem, does support dual-LTE Active but only SIM 1 slot supports VoLTE while SIM 2 slot only LTE non-VoLTE.

To test, simple put the SIM Card in one slot at a time. See if VoLTE is activated.

We have to thoroughly check both slots for VoLTE support. Most flagships support dual-LTE Active connections. Only the mid-range and low-end devices that are "compromised" in the modem capabilities.

Dual-LTE VoLTE active...



The only unknown situation is if our device support VoLTE but the other party / side of the call does NOT support VoLTE, will both devices downgraded to GSM spectrum or both devices maintain their individual spectrums...

Alright, hopefully the VoLTE will intact when calling non-VoLTE person/device... else, switching back and forth between VoLTE and GSM is worry-some...

Because 2G is more "popular" than 3G...(?) Lots of old and legacy devices still depending on 2G spectrum...

If "re-farm" 2G to 4G/5G, then, old devices cannot be used at all, and the burden to upgrade is on the "Rakyat" side 100%...

If "re-farm" 3G to 4G/5G, then, old devices still can be used and at the same time "Rakyat" can still use 3G phones but connect to EDGE spectrum (if still "reluctant" not to upgrade to 4G-enabled devices...).

So, "Rakyat" can stay where they are (zero Ringgit lost but suffer high BP due to EDGE speed....) or move forward with upgrading based on budget and provided subsidy (which is just merely zero-interest monthly payment with 12 or 24 months contracts) ...

Errr... so, the VoLTE icon/symbol disappears DURING calling to non-VoLTE line....?

Alright and TQ for the test.... It's confirmed no drop of signal for VoLTE devices DURING non-VoLTE calls...

Airplane Mode is that is the case for MySj app stucked...

DiGi is kind of famous for H+ signal at certain locations. After like 5 minutes, the 4G suddenly appears at the same location....LOL....

Actually, if we can "fixed" the calls to be on SIM2 slot only, then, SIM1 is prioritized as Data only (so that it can be connected constantly to 4G).

Eg:

SIM1 = data only = P1 webe #BEBAS Unlimited Hotspot 7Mbps = RM35/month
SIM2 = Primary number for calls/SMS/TAC/MSOS = Yoodo 4,000 minutes/month = RM12/month

With combo above, the phones will always be on data connection while calls/SMS is channeled to SIM2 all the time. Just ensure the line to be on data is slot into SIM1 always. Usually, old model and mid-range phones will set SIM1 as "more features" than SIM2 slot.

Not encourage to use e-SIM. But, can try to set the data on the physical SIM to see the data can be used or not.

Does that eSIM connect to VoLTE?

If the line is not connected to VoLTE, for sure 100% during call, the line will drop to 3G (until 31st Dec) or 2G (After 1st Jan 2022)

That's not good if the call only passed-thru after 5 seconds "hand-shaked".... but, after call ended, did the line auto-connect back to 4G...? or we need to airplane mode On-Off to force it connect back to 4G...?

LOL... looks like the annual report for year 2022 is as follows:
1) The Worst JENDELA Experience Award = AXIATA
2) The Best JENDELA Experience Award = ...???

Please rest assure (very standard and scripted reply by Customer Service ... LOL...) that the 3G cell towers have been "re-farmed" into 4G spectrum(s). Therefore, if the location that U visited "was" connected to 3G before; soon, starting from 1st March 2022 onwards, the device will connect to LTE spectrum(s).

Looks like the worst JENDELA's aftermath is AXIATA.

YooDo users are now feeling the "Edge" of JENDELA edy...

Hypothesis:

Last time, 3G towers are able to service hundreds of devices at a location.

Now, these 3G towers have been "re-farmed" to 4G but me's guess is NOT ALL cell towers are re-farmed (due to cost and deadline). Some are totally abandoned or downgraded to 2G (but may be re-farmed "in the near future" ; touch wood...) leaving ONLY a few 4G towers to serve the same VOLUME of devices...

Nobody does the study that in 5 years, the VOLUME of devices will increase for sure and during that time, more devices will suffer slower speed (aka major congestions) becoz telco never bother to upgrade the same location again and again and again...

Malaysian likes to fix what is not broken...

Since it will be broken starting 1st Jan 2022, it is our initiative to fix the broken JENDELA... the best option is to use dual-SIM device... use the SIM2 slot as backup if the SIM1 is not in proper service...

Me's combo is DiGi-AXIATA (SIM1) and Hotlink (SIM2)... since DiGi-AXIATA is not reliable at the moment, me's SIM2 slot has becum the equalizer all the time....

Conclusion:
It is mandatory to subscribe to two (2) telcos starting 1st January 2022....
