I recently switched from an iPhone 4 to the LG Transpyre and I am on prepaid. Everything works with the phone except text messaging. When I send a text message it says it sends, but it never reaches the person who I am trying to text and when someone tries to text me they get a failure message on their end as if my phone is off. On one attempt of sending a text message I did get an ERROR CODE:97. What could it be? I really like my new phone and I would love for this to be resolved.
