I noticed that lately Celcom (at least in my area) aggressively lit up Band 8 LTE on most of their towers here. At same time, it is noticeably harder for the phone to latch to Celcom's 3G band 8 even with manual band lock.

I set the phone to lock to band 8 3G only & most of the time the phone would connect to U Mobile's band 8 3G instead, not Celcom's.

Celcom's 3G B1 2100MHz still connects easily here.

Idk why, but Celcom doesn't easily let me to connect to band 8 LTE at my house..... but when it does (briefly), the indoor coverage actually way better before latching back to band 3 with around -120dBm signal downstairs & around -105dBm upstairs

Maybe I need to wait until 3G is completely killed here to get improved signal

Only U Mobile has 3G here in Kota Bharu (somewhere near Lotus's/Tesco)

First two is 3G from Thailand (TrueMove H & AIS)

Seems like 502 158 is (I think) more towards nationwide 2G roaming... I see mix of Celcom/Maxis/Digi frequencies in CellMapper

I also see complains from those three telcos (roaming on 502158)

Can confirm, U Mobile disabled data on 3G

Actually having headache why Celcom's 4G to 3G/2G handover (for making & reciving calls) is messy right now at my house since 3G shutdown thingy

And our family's Celcom/yoodo SIM (left & right one in the picture below) for some reason won't connect to 2G... even if it did, it'll just go back to no service after few moments (Celcom's 2G signal is not that weak at our house, the Celcom/unifi/yoodo SIMs locked to 2G only for purpose of detecting 2G signal)

Unifi 4G to Celcom's 2G handover works just fine , even the unifi SIM sticks to Celcom's 2G just fine without any issue if I set it to 2G only
And Yes, already reported to MCMC

Note: In the picture below, the left phone has yoodo SIM on SIM2, middle one has unifi bebas SIM on SIM1, right one only has yoodo SIM.
