'Remind' is an app a lot of teachers in Western New York use so that they can communicate to their students. It's a great tool, not to mention that you don't have to give out any phone numbers.

You will no longer be able to send free messages on the 'Remind' app starting January 28.

Verizon is imposing a fee on the app and 'Remind' CEO said:

As a startup company that’s in the education space, there’s no way that we can support that incremental cost,” Remind CEO Brian Grey told USA Today.

7 million of the 31 users of the app have Verizon. Users, both students and parents are tweeting to try and get Verizon to stop the charge.
