I JUST bought a new Galaxy S4 last night after having an iPhone for a long time. As soon as I get home I get an error code 34 and can not send outgoing text messages. I called technical support and she went through some process where we re activated the phone, it worked after that. I wake up this morning and get error code 97. I had to restart the phone and it worked. This is really annoying and I'm ready to take the phone back. I really like this phone and WANT it to work correctly. I don't have an air rave device as I've read caused problems with the S3. Please help! I don't feel that the people at the store really know what they are talking about.
