América Móvil seems to be tinkering with their NET10 rates and plans. A user on HowardForums reported getting an email from NET10 saying that they would have to enroll in Auto Refill to keep using the $25/month 750 minutes plan. With Auto Refill you register a credit or debit card on net10.com and the plan refills itself every month using the card.
Update: On their Facebook page, NET10 has confirmed the new Auto Refill requirement for the $25 plan and that existing refill PINs and cars would still be honored.
For now $25 monthly plan refills are still available from callingmart.com and can be found at thousands of convenience stores, drugstores and supermarkets around the country. As far as I know, these cards are still good. I can't imagine América Móvil (NET10's parent company) refusing to honor them and risking tons of negative publicity and allegations of fraud.
In other more positive news, most pay as you go refills on net10.com now give more minutes. Here's a comparison of the old and new rates.
|Price||Old Minutes||New Minutes||Days of Service||Old Price/Minute||New Price/Minute|
|$20||200||200||30||10 cents||10 cents|
|$30||300||400||60||10 cents||7.5 cents|
|$60||900||1200||90||6.67 cents||5 cents|
