i just changed to esim. just sharing my experience here.

So, I walk in the a maxis center two week ago, it took like 10mins.,then i walk out with the esim on my iphone xs max.

Few days after i changed i realize the hotspot is not working on esim. Then i come across this tread. putting back in the physical sim doesn't work for me (i dont know if i am doing it correctly, but the physical sim just not showing any reception anymore)

i called 100 twice, one guy ask me to wait but the call got put off, another one ask me to reset network setting which doesn't work.

So i went back to maxis center in Gardens. A guy spent like 15 mins god knows what he pressed on my phone and made it works. i tried ask him, he wasn't willing to share, just say you use vpn before and it will get block for hotspot, but i never did.
(note: he never put physical sim card in or whatever, just pressing my phone)

i travel a lot in asean, so i change sim frequently. right after my first trip, i realize my hotspot not working again after i remove the physical sim.

so i try google again. with the keyword vpn but got nothing. I remember the guy didn't actually do anything material, he was trial and erroring, like on off the mobile data, tweaking the setting here and there. so i decide to try my luck.

then....

i made it works, when i turn ON the roaming, the hotspot works like magic. and you can turn roaming back off. no need physical sim.




not sure if this is helpful for any other user. My takeaway of this story is, the telco cant help us when we have these kind of problem. Even in apple forum people have same problems, and the suggest solution is put in physical sim... there are too many phones too many customer out there.
