I have a Blackberry 8900 & I find it confusing!
Some of my friends tell me they're gonna txt me (not in my contacts) & later I don't get a text.
I tested it by using another cellphone not in my contacts & sent myself a text message, but I didn't receive anything.
Then I added the other cellphone number on my contact list & resent the txt and that's when I received it.
How do I change the settings or something so I can receive texts from anyone even if thy're not in my contacts?
