When you have completed all the questions, you can pause your Spot and upload your results via your Wifi at home, provided it's within the required timeframe for each spot, so you don’t have to upload a large amount of data with your mobile internet. The amount of Spots you can pause depends on how many StreetPoints you have earned yet. The scale is as followed: 5 Spots with up to 300 StreetPoints, 10 Spots as from 300 StreetPoints, 15 Spots as from 500 StreetPoints and 20 Spots as from 1000 StreetPoints.
