Can you send a link to the tablet you use for cockpit navigation that does not require a mobile contract in the UK

I am being told by retailers I need a mobile contract to use GPS in a tablet , some on this forum say not required

Looking to get a genuine link or model number so I can go and purchase.

Thanks ...

I have been using SD on iPads for years. All my iPads were 3G/4G models with a SIM installed and using the internal GPS. I fly an ArrowCopter, so reception is not a problem. Currently SD runs on my iPad Air 2 and my iPhone SE.

My personal impression from reading the formum is that iOS devices run more stable than their Android counterparts.Updates of the system and/or SD seems to pose fewer problems. But there are staunch supporters of either camp.
