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 my Galaxy Tab S2 for 2 years and it works flawlessly. there is a newer version now but if you want the S2 you can get it for 300EUR. I am not a fan of Apple products. With the S2 you don't have to worry about GPS, memory is expandable, there is a version that supports cellular and it only costs half as much as an iPad.
