Hi all. I am on the 15 dollar plan and I top up with 500 minutes every other month. I am using a Galaxy Note 2. Every time I try to send an SMS greater than 140 characters (which the phone tells me becomes an MMS), after I press send the android wheel just turns round for a while and then I get message failed. Anyone know what might be going on? They do tell me that I need to turn on network data but I don't have any data addons. Could that be it?
