Some of my friends' cell phone bills are out of control. What they pay monthly is outrageous. I opt to go another route. Here are three ways I save money on this cost. 1. Communicate via e-mail. E-mail still exists and people have no problem communicating this route. And, it's free! 2. Limit who gets my cell number. Some individuals just don't need my cell number or phone number period. So, I keep the number low. 3. Have short conversations. To me, a long, complicated phone call is usually something that requires face-to-face communication. What are your best tips for lowering cell phone bills?
