Can’t link my XYGPS to the app at all – XY Find It Review

I got my xygps a couple hours ago in the mail and I still haven’t been able to connect it to my app. Every time I try to connect it it’s loads and loads and then goes back to my sim, then it gives me a message saying there was an error activating the SIM and tells me to go to a certain website to put the serial code of the finder manually, then I go to that site which tells me to download the app and do it through there. That’s just great Ive been going in circles and i still can’t seem to activate this thing. Beyond frustrated right now that I’ve just given up and pretty sure I’ll just throw this thing in the trash pretty soon.
