Instant Messaging Charges? I received my bill from ATT this afternoon and saw a spike in text message charges, something in the 700 range. For the past 3 years I have never gone above 200 which pay for on my plan. Well, I just got my Moto Q and use the built in Instant Messaging software for AIM. Does the Instant Messaging use GSRP or do I get charged for each message via a text message charge?
