Thank you Peter for understanding. We are working hard with PayPal to fully comply with their business terms and conditions. Progress has been made and I really hope it can be shortly restored as an option so less users will have this problem. (And yes, don't want things happened on Neo900 to happen again.) Sprint should work on Pro1. However the actual signal strength will depend on your region. Pro 1 has LTE 25 26 and 41 which should cover all of Sprint's LTE network, The only thing is their secondary CDMA BC10 network's local coverage (Maybe talk to a Sprint customer service to check if your area is only covered by CDMA BC10) With Primary CDMA BC1 Pro1 is covered.
