Deliverability to T-Mobile experiencing issues.

Incident Resolved by T-Mobile.

We have reports that messages to T-Mobile are flowing again. However, we are still testing and are keeping the incident open until tomorrow morning out of an abundance of caution. We believe all messaging delivery to T-Mobile will be resolved shortly. Thank you for your patience and understanding.

We continue to see sporadic delivery issues to a subset of T-Mobile customers. This seems to affect a small number of T-Mobile subsidiaries. This has been identified as a problem at the carrier (T-Mobile) network level and is being widely reported by our upstream partners. We will keep an eye on this and update accordingly.

We are experiencing deliverability issues for SMS and MMS to some T-Mobile handsets due to upstream carrier issues. We are monitoring closely. Texts to T-Mobile handsets may return inappropriate 30003 error messages while this issue is being resolved by our upstream partners.
