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 ...

About the size taken by Skydemon on my iPad. I had Switzerland & UK installed. I have also some PDF document. Even after unselected the CH and UK country, "Document & Data" from the storage info on my iPad still display 1.86Gb. No big deal on my iPad, but size is un-explained so far.
