hey guys new snap plan out unlimted off peak 1am-7am for $5 for 3 nights ....not bad i suppose ...
How can I uncap my data?
Snap has a great new deal which enables our customers to make those large downloads without contributing to their monthly usage! For only $5, you can uncap your data limit for 3 nights, between the hours of 1am and 7am. All you need to do, is log in to your account and head to the purchase extra data page. By clicking ‘uncap your data,’ your rate limit will be removed between the hours of 1am and 7am for a 3 day period. You can pay then and there via credit card, or charge it to your account.
