Hi, I have managed to connect to LTE after waiting for 30 minutes. And I used AT+CFUN = 0 to remember the network setting. So it is working fine now. Thanks.

Are you using the same unmodified AT_client with the eSim? If so, could you contact iBASIS SINGAPORE https://ibasis.com/contact/ to check if they have any service updates or changes? There is the contact information for SINGAPORE on that page.

Thanks for the reply, I am currently using iBasis eSim. I just used this eSim a few days ago and it was still working. So the sim card should support my area.

Hi,

[quote user=""]+CEREG: 2,"02C4","0B49FE6A",7,0,15[/quote]

Reject cause 15 typically points to a subscription or coverage issue:

Cause #15 – No suitable cells in the tracking area
This EMM cause is sent to the UE if it requests service, or if the network initiates a detach request, in a tracking
area where the UE, by subscription, is not allowed to operate, but when it should find another allowed tracking
area or location area in the same PLMN or an equivalent PLMN.

What sim card/operator are you using? Could you check the sim card/operator support LTE in your area?
