Unable to disable or remove eSIM

[Bob2640]

Hello

On my Samsung S25, I’m unable to disable or remove my KOLET eSIM. I always get an error “couldn’t connect with SIM. Try again later”. However, the eSIM works and I'm able to connect with 4G/5G on different mobile networks.

I have tried the following, but nothing helps:

• Connecting manually to a mobile network that is not supported by the eSIM
• Clearing the cache and data of the SIM Toolkit app
• Starting the phone in safe mode
• Removing both physical SIMs
• Removing the Kolet app that was used to install the eSIM
• Reset mobile network settings
• Wipe cache partition
• Restarting the phone

The phone is up to date with all software updates. According to my provider Kolet, this is related to an known bug in Android that causes this problem on some Samsung devices.

Does anybody know a solution (other than a complete reset to factory settings)?

Did you ask Kolet support

And some suggestions

Thanks for the suggestions. The link describes problems related to locked phones in the US but that’s not the case here (in Belgium phones are always sold unlocked).

I have contacted Kolet support about a week ago. They let my try various things but unfortunately  nothing worked. They say they know of similar cases related to some Samsung models.

They are investigating it further it with their provider to find the reason behind. I don’t expect too much of it, so that’s why I’m asking it here.
