Then my friend tells me hes getting my text messages. Every one of them. So I get the phone back, call telus up and complain. The tech has me enter some number which opens up the config for the phone.

And low and behold I have my phone number sitting in the phone. Deleting the number stopped the text messages.

So lets think about this for a second. All I have to do to get your text messages is enter your 10 digit number into my old non active phone.

I would say security in text messaging is non existant.

FYI: Happened christmas of 2009 so it might be fixed but I doubt it.
