Pokemon-go – Will pokemon in pokemon go spawn without data access

So long as you are able to receive Mobile/Cellular Network Data and GPS, you should be able to wander around collecting Pokemon perfectly fine.

Also, depending on your village, there may be one or more of:

• PokeStops, which give you items like Pokeballs and Potions (and can be temporarily buffed with Pokemon Lures to attract Pokemon)
• Gyms, which can be captured, trained at and fought by members of the three Pokemon teams (Red, Blue, Yellow). You will be able to join a team at level 5.

You may be able to check this without downloading the game by using an Ingress Intel/Portal checker (as Pokemon Go is based on the same locations), however note that currently not all Ingress portals are Pokemon Go spots.

I noticed this too. It could be a bug in the game that causes the GPS to be inaccurate with the paw prints. A Growlithe showed up near me, allowing me to capture it, but my grid says 3 paw prints for all the 9 Pokemon, even with the white pokeball loading symbol gone (done loading). Also, grass/leaf patches don't always mean there is a Pokemon. I ran far to a rustling patch before, but all the Pokemon on my grid were 3 paws away. More info on rustling leaves

Although I believe this is an unintentional bug by Niantic, I would recommend searching primarily for just 2 and 1 paw print Pokemon if it shows up. The 3 paw prints seem buggy, even though it means 150 meters to 200 meters within range according to this answer: Step Distance Try to go with a group a friends so that you cover more area and find Pokemon more easily. In addition, you can try going toward leaf patches for a slightly higher chance of an encounter.

EDIT: As of now, I have iPhone 6s with version 1.0.2 in the app store of Pokemon Go. The in-game version says 0.29.2
