You would have done well to do a little bit of research before you made your purchase. There are entire forums and groups dedicated to the pro's and con's of prepaid phones. Net10 and Tracfone are designed for people that use ~300 minutes or less per month. You can keep a cell phone active for emergency use with Net10 for as little as $10 per month and $7 per month with Tracfone. For these types of users they can't be beat. This service is not optimal for data or picture messaging. They have recently activated these features but again you will pay for them. Who really NEEDS a new ringtone? Why would you send a crappy digital picture to someone taken with a 0.3 mega pixel camera phone? Again it is for people that want simple and reliable phone service. (The both Net10 and Tracphone use AT&T's network but AT&T charges you $0.25 per minute while is is only $0.10 with Net10)
Customer Service. Net10 and Tracphone are owned by a Mexican telecommunications company. Their customer service is based in Latin America and english is a second language for their reps. If you use simple terms and speak clearly you will do fine. If you get mad, start yelling, and talking fast then you will get no where. Again, these companies are not known for excellent customer service for english speaking customers, 5 minutes of research on the web would have made that very clear. (Verizon and AT&T customer service will send you to a call center in India. Is this really any better?)
The review is right though. You do get what you pay for. In this case Net10 is the least expensive way to get cellular voice and text service.
