Can I use the Lumia 635 as GPS without a phone plan?

[WPCentral Question]

Hey there,

I have a Lumia 521 that I use as just a GPS and mp3 player. I am wondering can I do the same with the 635. Also can I do the same with the 1020 because I like the camera.

I do this a lot with my HTC 8S when I travel. Offline maps are best.

What about getting a Lumia 635 without a data plan (strictly for Windows 10 Preview), and WiFi tethering to my iPhone Personal Hotspot? Would I then be able to use HERE maps with the full experience I would get on a phone with a data plan?

Sounds correct to me...
