I have been checking around for prepaid for my daughter for Christmas. My hubby has virgin mobile which is ok..but Alltell has a prepaid where you only have to add mins. when you need them, also you must use the phone for a 1 min call per 30 days or you get charged a 4 dollar fee...but as long as you use it 1min per 30 days your good to go...coverage map is good as they use verizon towers also. I have a plan with Verizon and I dont have dropped calls or anything and I like the service. So from what I can tell I am going to give Alltel a try for my daughter since you do NOT have to top up every 60 or 90 days only when needed....hope this helps?
