RingPlus, is a new Sprint MVNO that generated a lot of excitement last week when it launched a free ad-supported mobile plan.
The free plan includes 300 minutes and 50 texts per month. Additional minutes and texts are 2¢/each. Data is currently not available but Ring Plus says it will be soon for 2¢/MB. In return for free mobile service users hear advertisements during the time between when a call is placed and the called party or voice mail answers.
The free plan is described as a promotion with limited availability. A couple of days after launch it was suspended with a promise that it would reopen this week.
True to its word, RingPlus posted on Twitter and Facebook last night that it would be accepting new users starting Tuesday Sept. 3 at 8 AM PDT until an unspecified subscriber limit is reached. If you miss out on Tuesday, the sign up window will reopen again Friday Sept. 6 at 10 PM PDT.
The free plan is only available if you "Bring Your Own Sprint Phone" (BYOSP). RingPlus can activate any clean ESN Sprint or Sprint MVNO phone with the exception iPhones. During the plan's initial availability last week it was also possible to activate Boost and Virgin Mobile phones. However, Boost and Virgin Mobile phones are not allowed on other Sprint MVNOs so I wouldn't be surprised if they are blocked when activation reopens Tuesday.
When the free plan was available last week, the sign up procedure was to go to https://my.ringplus.net/device_validation_requests/new and enter your phone's ESN. If your device was eligible you could create an account and activate your phone immediately. To get the free plan choose "BYOSD" from the plan drop down. A valid email address and a credit or debit card number (for overages) is required. I'm not sure if the procedure will be the same this time. I recommend following @ringplusmobile on Twitter and liking the RingPlus Facebook page for updates.
Update: No Longer Available - RingPlus Launches Free Ad Supported Mobile Service
