I originally thought that my S20 would be dual SIM capable, I bought it for that reason. However, upon opening the SIM slot, only 1 physical SIM card will fit. Other tutorial videos show that a 2nd SIM should fit into the SD card slot but it doesn't for my S20. Upon some research, there is a version of the phone that will take eSIM. Upon chatting with the customer support and giving my IMEI 352620111069711 Model Number SM-G981U1 they said that as of now the S20 5G does not have the updates enrolled for eSIM capability, and that the developers are working on it and that it might be released by the end of the year. If I had known this, I would have chosen a different phone or model. However, it's not very clear on the Samsung shop website which version you are getting, this should be made more clear. So as of now, I am abroad with a phone that cannot take a 2nd SIM and am forced to use an additional phone for this purpose. I hope the developers can make the update for the S20 for eSIM capability.
I leanred this when T-Mobile tech support connected me with Samsung's tech support to resolve this issue of eSim and Samsung passing on the blame to the carrier. The question the T-Mobile tech asked Samsung tech support was that how come Samsung doesn't push out all the eSim updates to all the various built numbers, just like in iPhones or other manufacturers. There was no response from Samsung.
I have the Note 20 Ultra and I was pushed around between Samsung and T-Mobile technical support teams. Samsung would tell me the carried needed to push down the update but the carrier would reject it and ask me to get back to Samsung as they is their responsibility. Finally, the tech support from T-Mobile made a three-way connection with me and Samsung's tech support to address this issue with eSim. We were on the phone for over an hour. I have the tickets number to prove. In that call, the carrier told Samsung tech that Samsung is the one to push software for security and eSim. The carrier branded phones have a slightly different built number and Samsung pushes eSim based on that built information. (Did you know that???)
A direct question was asked of Samsung that if Samsung believes there is anything the carrier should do, then Samsung tech should say that. The tech form Samsung asked for my IMEI number, fumbled around, tried everything, and nothing work. We were on the call for over an hour. Then, the Samsung tech said a manager would call me for a decision. A manager never called. We have called back and tried to speak to a manager. They gave me another ticket number for a manager's call. Yet, none had called. I called back three times to speak to a manager. They placed me on hold until I got disconnected.
So, this issue of eSim has to be pushed by the carriers is nonsense. TOTAL NONESENSE. All the carriers have a different built number and Samsung pushes eSim to them based in the built number. Simply, Samsung has not done that to the unlocked phones that were bought directly from Samsung. Why? These individuals don't have clout and power to demand remedy. No agency.
Deceit seems to be a culture thing with Samsung.
It is a hideous practice by Samsung.
