WiFi and tracker recommendations

[FordyX72]

Hi all. Hopefully buying our first motorhome this week after many years of using Mum and Dads until theirs got stolen.
So, recommendations on security and a tracker please.
Also as we need to stay connected for those days away when we're 'working from home' I need some sort of Internet connection. I was thinking just of a 3 PAYG HotSpot for the UK that we can slip a French PAYG sim in when over there, but any other suggested ideas need be considered. Cheers

Thanks for that, will look into it
