I have an LG Xenon with Bell Mobility. I can't do *3282# because I don't have AT&T.
If I can't find out on my phone, where is it on my bill? Some friends told me that they find out how many texts they get within one month on their bill.
Answer on How to find out how many text messages you have sent within the past month?
You should be able to contact the phone company and ask the customer service department about your problem. Look on your phone bill if they have a toll free number or a code you can dial on your cell phone. they should be able to help you out.
