Sim card Manager missing

It would be in settings, connections, scroll down and look for sim manager.

It's not in my device settings

I can use other networks except for the e sim which I feel is being disabled

Do you have the correct model? Ending in a u or U1?

Running up to date software?

Hi @Daviday242, we're here to help you.

We're more than happy to get you on the right track of activating your eSIM!

The Galaxy S20 contains an eSIM inside the phone and requires you to visit a Local AT&T Store Near You to receive a QR code that's printed on eSIM card.

Once you have the QR code, you can follow these instructions to Install Your eSIM.

If you have AT&T postpaid wireless, make sure the eSIM is on an active wireless plan, then download it over Wi-Fi. If you instead have AT&T prepaid, you will have to contact the Prepaid Department for assistance with eSIM activation. 

We hope this information helps. Thank you,

Dominic, AT&T Community Specialist

Hmm I see a pointless trip to an AT&T store in your future.
