Hi I just started usuing prepaid SIM card and I also started to refill money by refill card. After I refilled, I got many messages from 78108858," The last transaction cost is .035(or something else). Your account balance is $23. To refill your account go to www.att.com/mygophone." I don't know why they send messages to me many times. Moreover, my balance account still decreases.
