My son has a Straight Talk & loves it. No problems. He was using the unlimited for $45 a month but is changing to the $30 for 1000 min./ 1000 texts. He said he would be able to talk on the phone 30 minutes every day, & do 30 texts every day (with a few to spare) to use up the smaller card. He's had the high dollar contracts that are hard to get out of & says he will never go back. There is also internet service on the phone but he said he never uses that.... Google Straight Talk Walmart & there are testimonials.
Me.......I just use a trac phone. It is usually laying on the counter in my kitchen. I keep it for traveling & emergencies. I like not being at everyone's beck & call all day every day.
