Hello @Margare_1908978 . As I understand, the personal hotspot is a feature of the device, rather than the SIM card.
I can certainly use my iPhone (with Smarty sim) as a hotspot and connect my laptop to it, so there should be no problem.
Have you tried to connect any other device to the phone? Could it be an issue with the TV recognising the phone's hotspot? Maybe just a settings issue e.g. have you got the hotspot password protected?
