eSIM in TCB etc. is not the same as a SIM card from a mobile operator. Also not a eSIM from mobile operator.
15 years old SIM card from a mobile operator don’t work in a new phone.
Also is Combox a old phone and ATM a new phone.

No I never change my sim from 2003. So your info it's not correct please search on Internet. That is all incorrect because I never hear that sim not working or not getting 4g or 5g like my sim does

I don't know in which magic land you live, but here in Europe it DOES NOT work that way...

Don't know in what magic land you live yourself, but the SIM I have is from 3G era (t-mobile, Netherlands) and connects to 5g. Already had to cut it from normal sim-size to nano-sim.

Here we are discussing eSIM from Combox/tcb or plastic sim from mobile operator.

And what is the difference exactly??

P.S. OK, I definitely had to replace my SIM going 3G->4G in my phone. So maybe some operators do something to make it universal while other don't.

Exacly? BMW don’t use plastic SIM cards.

So chip case is different Many chips do that. Functioning of internals still the same.

[user_530d]

Case and internal is different. And Combox SIM don’t work in atm. This was the question I think,
…mobile connection to the network doesn't mean it works.

Even "normal" SIMs evolved from 8kb of memory inside to 256kb. So the one from combox seems to have too little memory for ATM (or 4G maybe). Exactly why you get the fault that internal memory full. That does NOT mean that they are somehow else different.
