We are currently experiencing delays in delivery receipts (DLRs) for SMS sent to the T-Mobile network in the US. This means message statuses may not be updating in real time. Actual SMS delivery is not affected. We are working with our carrier partner to resolve the issue and will provide more information as soon as available.
