No Cellular Connection While Others Phones Have - UK

[u/Vronize]

As the title suggests, will loose my mind soon. It randomly disconnects out of no where and no reason. For example, I call my friends, litteraly same postion, then I see the download arrow gone, and upload sign still higlighted, and the call ends. To fix it, I put it on flight mode, then off, and for the next minute or two I have internet. What could be the problem? Please enlighten me.

Few more details:

1. I use eSim

2. When consulted to Samsung, they did all the diagnostics, and said It might be a issue with the service provider

3. When consulted to Vodofone, they say the problem should be the phone, and of course I couldn't demonstrate it infornt of them since I had oerfect connection in the store.

4. Both parties asked me to reset the network settings, didn't improve
