I just heard that T-Mobile has opened up its contracts with states and the federal GSA to nonprofits. This means you have access to an 18% discount on service. If you pay T-Mobile directly you can use this discount to provide service to the folks you serve. They do not have a system for the folks you serve to pay T-Mobile directly.
This could be a way to offer hotspots to library patrons or to families you serve that don’t have access at home. (Get pricing. And check coverage areas before you get into any contracts!)
Other providers may have similar service – and if they do I’d be happy to post it here too. (Just send me info firstname.lastname@example.org or post a comment below.)
