I am new to Square - I run a seasonal mobil business and want to be able to run credit cards for customer sales. I wanted to know if anyone had personal experience with using a pre paid phone with their reader. There are several pre paid providers that offer a Samsung Galazy J3 - which shows as compatible. However, I dont' know how much data I would need to buy to rubn, say, a doen or so transactions in a few days to maybe 25 in a week? And helpful hiints?
