Description:
Issue: HSI Return Authorizations (RAs) and return labels were not generating for the correct IMEI for approximately 700K active HSI subscribers. The issue was identified and resolved in April 2026; however, the original start date of the issue is unknown.
Impact: Customers completing a return or exchange may have been incorrectly charged a Non-Return Fee (NRF) because returned devices could not be tracked properly. While the Shipping Label Tool may have been used to recover devices, it does not accurately close the original return or exchange transaction.
Workaround:
Customer Assistance Process:
- Research the originating return or exchange transaction.
- Determine whether an RA/Return Label was generated:
- Yes: Follow standard research processes and only if applicable, adjust the NRF.
- No:
a. Verify whether an HSI NRF was charged to the account.
b. Using the returned device IMEI, confirm whether T-Mobile received the device (Retail or warehouse).- If received and the NRF has not been adjusted, apply a credit.
- If not received, the NRF should remain valid.
