No, SIM card only.

Hello, the tablet I bought, the Galaxy Tab A9+, does not have this, it is SIM-only.

No, they are not eSIM-capable! Today I wanted to order an eSIM card for my Samsung Galaxy Tab A9 via the Fraenk app (I already use a SIM card from Fraenk in my Xiaomi) and was immediately shown the message: "Your device does not support the eSIM." You can also make it valuable not eSIM-capable in other ways, which dubious suppliers/people unfortunately keep claiming here!

no, it definitely does not support esim, as I realised today.
But according to https://esim.me/ it can be made esim-capable. But it costs accordingly...

A9+ does support esim! Sincerely

Yes, the Samsung Galaxy Tab S9+ supports eSIM. The embedded SIM card allows you to use mobile data without a physical SIM card12. However, if you want to download an eSIM profile, please note that the app may encounter an error3. In the specifications of the Galaxy Tab S9+ you will find a reference to dual SIM, with eSIM acting as an embedded SIM4. This means that you can use both a physical SIM card and an eSIM. Have fun with your tablet! (Answer from Copilot)

Unfortunately, I don't know that myself.
I'm sorry.
