Connectivity
- Network
- 2G / 3G / 4G2G, 3G and 4G. No 5G, whatever some listings say. There is no band 71 either, so T-Mobile's 600MHz low band is not covered.
- VoLTE
- Unknown
- SIM
- Dual SIM + microSDTwo nano SIM slots, the second shared with microSD, so it is two SIMs or one SIM plus a card. No eSIM.

- Works on
- T-Mobile, Verizon
- Carriers
- Sold unlocked. Unihertz's own US compatibility list names T-Mobile and Verizon outright, marks AT&T as working only with whitelisted models (the Jelly 2 and Titan 2, not this one), and flags most US MVNOs as varying by region and city. Because the phone is not Verizon-certified, Unihertz says a new Verizon SIM has to be activated in another handset first. It also refuses returns over carrier compatibility.

Notes
Full Android with the Play Store, so this is a small phone rather than a simple one. It keeps the headphone jack that the newer Jelly Max drops, and Unihertz began rolling out Android 16 for it at the end of August 2026.
