Hello, I am currently using a HTC phone under m1. My contract ended earlier this Feb, and I decided not to recontract since I don't want to get another handset. Now I am really confused about how m1 charges data without any mobile plan for customers like me, because I don't have local data bundle anymore. Right now my data usage is about 258MB. How do I calculate my bill for data usage? Thanks in advance for replying!
