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 ...

Hi everybody,
any new recommendations which tablet to use in 2017?
I'm new to SD‌ and currently using my old WindowsPC (2013) and an iPhone SE (2017), both working perfect with SD - congratulations to the SD-team :-). Now I would like to buy a new iPad‌ (to use instead of the iPhone SE, because screen is to small), but which one?
I'm thinking of a 9,7" Multi-Touch Display, but do I need:
Wi‑Fi + Cellular or just Wi-Fi? 32 or 128 GB? Anybody can help?
Anyway, the coulour should be space grey ;-).
And are there any good alternatives‌ with more or less the same specifications but for a lower price?
I would use the device only to go flying, so no other gimmicks (special camera or so) are needed.
Thanx for any good‌ tips.
