I have the LG EnV Touch. I do not have a text message plan whatsoever, but I occasionally text friends once in a while. About last week texting was fine, but these past 2 days, everytime I send a text it immediently says "Send failed. Would you like to retry?" and "Message is not delivered. Service is unavailable." I tried *228 numerous times. I restarted my phone and took out the battery. Please help!!
