when i send messages, they go to the outbox labelled as failed.
the reason is cos of invalid phone or message number.
strangely enough, it only happens to some of the people i want to send messages to, not all.
P.S. there is nothing wrong with their phones.
Maybe try sending them the message by just typing in their area code and phone number instead of selecting their name from your phonebook. Maybe the number is entered in with invalid characters or something. Like I know sometimes the phone will save numbers like +15616259856 instead of just 5616259856 Just try sending the message with thier area code and number rather than the +1AreaCode&Number
