If you are considering getting your teen or young adult a cell phone and don't want to worry about overages that result in huge bills, consider getting them a Straight Talk Cell Phone. I bought one for my teenage sister a few months ago and it has worked out great. It can also work for those of you that don't want the hassle of signing a contract or worrying about a credit check.
If you haven't heard of Straight Talk before, it is a service from TracFone Wireless. TracFone Wireless is largest no contract cell phone provider in the US.
Straight Talk was designed to simplify wireless costs without having to sign a contract. They offer 2 simple plans: Unlimited talk, messages and data nationwide for $45 or 1000 minutes of talk time, 1000 text or picture messages and 30mb Data for $30 per month.
You basically pick your cell phone (they offer 3 choices), pick which plan you want and pay. If you are worried about coverage, the service is comparable to that of the big carriers as indicated by the map below.
You can purchase Straight Talk online (see affiliate link below) or at participating Wal-Mart stores.
