Apple and Android seem to be the leaders in the mobile phone industry. The one that you have originally seems the one that most people stick with, familiarity is the most important thing with a phone. From what I have seen, most people who switch operating systems seem to have difficulty adjusting to the new system. For that reason alone, I would stay with the one you are most familiar with, especially since you are looking for a basic phone system. My wife likes consumer cellular and her phone is the identical model that I have from Tracfone, however, they both have similarities but function differently. Her phone costs about $30-$35 a month and I pay about $220 per year for the same service. We are both on the Verizon network. It is like Chevrolet, Ford, and Plymouth, everyone had their favorite brands of cars back in the 1960s and the one that they like was the best out of the 3 different brands.
