PRL Update for Improved Roaming

If you have a hotspot as part of our Contributor or Contributor Plus memberships, we have big news for you! We are pleased to let you know that another roaming update will take place this weekend for our mobile hotspots. In order to receive this latest Preferred Roaming List (PRL) update, please restart your hotspot this Sunday (05/02/21) and keep it powered on this Tuesday (05/04/21).

Once your hotspot accepts the PRL update, your service will continue on the Sprint network as normal. With this update, your device will also have improved roaming capabilities on the T-Mobile network. Roaming on the T-Mobile network will only occur when your device is no longer on the Sprint network, and where the T-Mobile network is available. For those of you who have been our members for a while, you may remember that a similar PRL update happened last fall to expand our hotspots' access to the T-Mobile network when Sprint is not available. We expect the effects of this PRL to be similar to the previous one in terms of increasing access to T-Mobile's network as a result of the merger between Sprint and T-Mobile.

Your Calyx Institute membership benefits will still include unlimited 4G data and no throttling, as always.

If you are having questions about this PRL update, we recommend reaching out for additional info to Sprint at 877-879-5031 and tech support at 877-216-9603. If your device experiences any issues, please call tech support at 877-216-9603 to troubleshoot and get started on a warranty replacement if needed. Don't hesitate to email us at if there's anything we can do to make your Calyx Institute membership great!
