RingPlus MVNO took to Twitter yesterday to announce that it will be offering their $6/month promotional plan again today (12/17) from 10 AM to Noon PST. The plan includes 300 Minutes, 50 Global SMS, and 10 MB of data. Extra minutes, messages and MBs of data are 2¢ each.
Unlike previous RingPlus promotions, which were limited to a certain (unspecified) number of signups, this one is time limited. There will be no limit to the number of new activations on the $6 plan but the signup window will only be open from 10 AM to Noon PST.
To use RingPlus you need a Sprint phone that's not currently active on Sprint or a Sprint MVNO. It has to be a Sprint phone, not a Boost or Virgin Mobile one. In addition, iPhones, BlackBerrys, Palm phones, PTT devices and most Sprint phone models released in the last 12 months are NOT allowed. There's a list of allowed phones on the Ring Plus Site. You can also check if your phone is eligible by entering its MEID or ESN serial number at https://my.ringplus.net/device_validation_requests/new.
To get the $6 plan, go to https://my.ringplus.net/device_validation_requests/new between 10 AM and Noon PST today, enter you phone's MEID or ESN and choose the "$6 - The Afterhours Plan" from the drop down. That plan will only be available during the promotion. If you don't see the $6 plan, try clearing your browser cache.
