Sprint Freemium MVNO FreedomPop has made some changes to their Terms of Service effective 2/3/16. You can view the previous terms on the Internet Archive if you want to compare for yourself. The main changes affect how Auto-top up works:
1) When Auto-top up is enabled, you will now be charged $15 (used to be $10) if your remaining data goes below 100 MB and you have a cash balance under $2. The $15 is added to your balance to cover potential overages.
2) You must now have at least $5 in your account to turn off Auto-top up. If you don't you will see the warning above advising you that if you turn Auto-top up off you will be charged $5 which will be added to you balance. When Auto-top up is turned off your service with stop when remaining data is 100 MB or less. FreedomPop says they do this to protect themselves because the usage data they get from Sprint is delayed by up to 3 hours and they could be left holding the bag by customers using up a lot of data in a short period of time.
Users who turned off Auto-top up before 2/3/16 can apparently keep it off without having to pony up five bucks.
Customers who use auto-top up or pay $5 to turn it off need to keep their eyes on their account balance to avoid losing it. FreedomPop has a long standing policy of expiring plan balances after about 90 days. The FreedomPop site says balances expire after 30 days but in my experience it's more like 90 days. The good news is that you can get your expired balance back by clicking a reactivation link on your FreedomPop Billing Overview page. I don't know how that link is available after the balance expires but it seems to be at least 30 days.
