Anna We have shifted our data collection to mini tablets with no data plan outfitted with an external GPS device. We use iPad minis and a Bad Elf Pro+ but there are many other options. Having no data plan means no monthly cost but requires WiFi to upload data which can be a pain if the WiFi is down at the office. We use ArcCollector on the tablets. We have had just as good luck with ArcCollector on smart phones although the smaller screen size means data collection is more challenging.
