The Ting iOS app does not support my iOS 5 device (requires iOS 6+)
and the Ting android app does not support my Amazon Kindle HD'7 2013.
Sprint supports the billing service https://check.me/ and the check.me app on both devices shows usage and notifies me when I reach the plan limit.
It would be awesome if Ting could provide similar features based on check.me.
What do you think?
