Is the SIM card different for prepaid and contract services?

How do I switch to an eSIM when I have a physical SIM? Stores won't help you as soon as you say you have prepaid. I want to know before I get a new phone that requires one for dual SIM.

I am no longer able to add minutes to my son's iphone. I think it's because I let 90 days go by without adding minutes. How can I add minutes, and if I have to get a new SIMS card, will he be able to keep the same phone number?

We have an Ewon Flexy 201/205 that will not connect to the internet. It requires 4G, I believe it uses PPP and works fine with a T-Mobile sim straight out of a phone but not with two different AT&T sims. All three sims work in an AT&T mobile phone but not in the EWON. Pretty sure it is somet
