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.
