Switching between prepaid plans when out of country
I plan to be traveling out of the US for months at a time (minimum 3 months), then back to the US for a short time, then out of the country for another 3 months, etc. While outside the US I will get a local SIM and do not want to be paying for service in the US that I won't be using. I want to keep the same phone number for the duration. It was suggested that I get on a monthly prepaid plan while in the us, then change to a $2/day used plan while out of the country. I won't be using minutes at that time but it will allow me to keep my phone number. I realize that, when I switch from a monthly prepaid to the 2$ plan before the month ends, I will lose those minutes. I will need to add enough money to the $2 plan to cover the number of days I will be out of the country. When I switch back to the monthly plan, will the money in my $2 account be used to pay for the monthly plan? Is there anything else I should be aware of when doing this?
