Context, phone is samsung a15 5g, tablet is samsung a9 with no sim slot. Used the above to make phone calls from the tablet for a while, which works well when it works. Recently all I get is failed call with the message Can't make call. Make sure your phone is connected to a network and call and text is on both devices. Which it is, this as happened 3 times, manage to get it working by logging out on both devices, leaving call and text, login again works for a few days then fails again. Unless anyone as any ideas I'm just going to just bin the idea off. Incidentally text messages work all the time.
