Could be related to AT&T's 3G shutdown, as Celcom is using AT&T as roaming partner. Maybe try roam on T-Mobile?
AT&T will eventually go 4G/5G network only

QUOTE(marshtomp @ Nov 17 2022, 09:26 AM) Something like that happened to my Tunetalk recently. It turns out that it's AT&T restricting the type of phones allowed onto their network. I researched for a long time and during one reboot, I noticed I hooked onto AT&T for just a split second. So that told me the SIM was working but AT&T kicked it out after that. Weird, roaming devices & SIM shouldn't be affected by the AT&T whitelisting, I've just asked someone familiar with ATT What I did was to buy a phone on the approved list: https://www.att.com/idpassets/images/suppor...ATT-Network.pdf , and Tunetalk SIM card immediately worked. |
