Cell phone bills are the biggest pain! So over the years i've found a few ways to help me save money... thought I would pass them along.
1-800-Free-411, instead of using 411 or 1411 and getting charged anywhere from $.75 - $1.50 per listing, just call, that number and although you have to listen to a stupid advertisement its absolutely free. I'm always using that number to find businesses and stuff around me... its great.
Also when you make a call to someone and you get their voicemail, depending on which company they are with you can usually hit 1 or # right when their voice starts and it will take you right to the beep where you leave your message... i know that sounds stupid, but did you know that your phone conversation is 1 minute and 1 second, its rounded up to 2 minutes on your bill
The last way to save money I've found out is to send text messages via internet anytime your around the computer and need to send a text. Every major cell phone provider offers text messaging through their website... this way you aren't charged like $.10 per outgoing text message.
I know I sound like a penny pincher, but I've had 2 cell phone bills over $600 (just 1 month) and many $250-$350 cell phone bills in the last 5 years!
