- Works on
- AT&T, T-Mobile
- Carriers
- Sidephone USA says T-Mobile and its MVNOs are fully supported and that AT&T works, though coverage can be limited in places. Verizon and Verizon MVNOs are not supported. No PTCRB and no carrier certifications, and LTE bands 13, 66 and 71 are missing. Sidephone USA also sells its own optional plans, Sidephone Mobile, which run on T-Mobile's network, and a Sidephone SIM ships with the US retail phone. The maker recommends it as the simplest setup, but it is not required.
Where to get one
- Regions
- United States, Canada, United Kingdom, Europe, Ships worldwide
- Countries
- Sold from a US store and an international store that ships to 60+ countries and regions, not everywhere

Notes
No carrier certification, and LTE bands 13, 66 and 71 are missing, so Verizon is out and coverage can thin elsewhere. It is de-Googled, so anything needing Play Services will not run. The keypad is a magnetic tile you can swap for QWERTY, a media wheel or a game pad.
