I'm interested in using Vespucci app to help contribute to OpenStreetMap but I do not have cell service, I don't have data or GPS, it's wi-fi only so no working GPS.

I can't figure out how to use Vespucci with a offline phone when outside.

GPS works with a fully offline and in airplane mode device. GPS is 100% passive, unless you want faster initial fix, for that A-GPS comes into help and require data connection.

But plain nice old reliable GPS is 100% passive and works fine with totally disconnected devices. Actually original GPS devices (who remmebers those...) where 100% offline. Maps on the SD card, no live traffic or accidents data, nothing fancy. Yoiu had to purchase yearly maps updates too, what old times.

I think that there's been a misunderstanding: the OP said that he has no GPS on the device, so I guessed that he wanted to map the WiFi networks, so my comment.
