I guess that there is ore there will be a online service to play some switch games online, but it can't be the official nintendo switch online, it would brick your switch for sure. But there will maybe have a server, but not connected with nintendo servers. So just such as riiconect24 . You could'nt play with your friends that do not have the same online service and im not sure that there is a service almost published. And if your switch is patched, you need a chip. It's really costing a lot, and it's pretty complicated. You can continue searching for a banned unpatched switch, (only the XA??????????????? Have some CHANCES to be unpatched. I recommend you to choose the more little serial number like XA?000000000012 would be better, i reccomend you to check here in the alphr dot com tuto how to check if your switch is moddable
(I had a XKW for christmas
)
I hope you'll be great with your modding!
