Hi all,
I've had this problem for a couple months now and it's gotten to be a real annoyance. For some reason, some text messages I send never make it to their recipients, and it is not exclusive to one network or person as multiple people have said they never received my message.
For some contacts, nearly every time I send a message it never goes through, which is really annoying. Tried every trick I know, including *228, setting "roaming" to on, turning on and off phone, doing network reset. I'm running out of ideas. Any help would be appreciated.
