In a previous post, I have written on how to add eSIM functions to POCO X3. This is using the 5ber SIM card and the app. I have tested this to be working on Android 14.
When I upgraded the phone to Android 15, the 5ber app stopped recognizing the SIM card. The same applies even after I have upgraded to Android 16. The SIM card is working fine as I can see there is an EID code in Device Information (*#06#). A few internet searches showed that 5ber has some financial difficulties and were bought over.
The SIM card appears to be from China Mobile, (CMLink). I installed the CML app from Playstore and it could not recognize the SIM card too. The CML portal for purchasing profiles seems to be working but there is no facility to add third party profiles. After more internet searching, I found an XDA thread on using an open source app OpenEUICC to work with programmable SIM cards to load profiles.
OpenEUICC is a Local Profile Assistant for Android devices. Root is required as installation is via a Magisk module. Not surprising as this is installing system level functions.
On a hunch, I tested using the OpenEUICC app to load a profile. Using the + icon and scanned in the QR code, the profile was added successfully. The way to track is to tap on the ICCID to reveal the number and match against your order.
Tested the profile by connecting to a Malaysian Telco. The app’s UI left much to be desired, but it works. I could connect to the Internet and download several large files.
