I have an old phone I am trying to try this service with (cause why not its free) but when I go to register the account it errors out saying something went wrong. It says my phone is eligible for the program. Also for this plan you are charged 10 dollars then that is deducted if you going over your limits and once the account is at a zero balance it will charged another ten dollars. Pretty good if you dont use a lot of minutes, texts, or data. Only being charged 10 dollars for a year of service not to shabby.
