I have tried everything but even turning off send as SMS does nothing. No matter what I do I get charged for every text even when I have access to wifi. Anyone else having this issue? I'm on a pay as you go plan and I get and send a lot of texts. Its costing me quite a bit. Would love to know if there is a fix. I even took out the Sim card and as soon as I try to send an Imessage text it says, "No Sim Card" and won't send the message. :-(
