Condition: A Grade
A Grade (A-Stock) units are lightly used, fully tested, and working, and may show very minor nicks or scratches. Units are supplied as graded; ask your account manager about packaging (original box, accessories, or handset only) when you request a quote.
Network and compatibility
The M919 is a T-Mobile LTE build sold here GSM unlocked; see the network status line in the table for the listing's lock state. It has LTE for data, but VoLTE on a 2013 handset depends on firmware and carrier policy, and US carriers now require VoLTE for voice since 3G closed in 2022 and T-Mobile's 2G GSM ended on August 3, 2026. Confirm with the carrier before buying for US activations. Unlocked units also work on GSM and UMTS networks abroad where the bands match.
Resale fit
- Prepaid and MVNO counters on T-Mobile-based networks, once the carrier confirms the model is still accepted.
- Repair shops that stock S4 screens, batteries, and housings for walk-in work.
- Export to GSM markets where a Snapdragon-based S4 with a removable battery still sells.
