We have relied on Tracfone as our only cell phone system. We have owned it for 4 years and finally our original phone's technology (CDMA) became obsolete and Tracfone sent us a free new phone (GMA technology that allows us to call internationally as well) which arrived the next day. We were able to transfer the remaining minutes and the old cell # to the new phone seamlessly, with one customer-service call that lasted 20 min. The customer rep (who was in Belize) spoke good English and was very courteous and professional. We wholeheartedly recommend Tracfone for those who wish to have no long-term contracts and only use a cell phone for real reasons - not to yak-yak endlessly and meaninglessly. This is a great product!
