I just got my Wife a ZTE Z221 model GoPhone. Every time the phone gets used an email is received from AT&T saying something like "$.10 used. $---.-- funds remaining.". How can I disable these annoying messages? She doesn't want to be reminded how much time/funds still remain after the phone gets used. Unless the minutes roll over the next time the minutes are renewed, she will never use up the $25 worth of minutes in 90 days. So how can I disable these annoying emails from AT&T?
