Sunbeam Wireless
Sunbeam F1 Pro (Oak / Aspen / Juniper / Cypress)
A rugged flip with a real menu of software builds. Pick how dumb you want it.
$330 to $389
Sunbeam sells direct at $359 for eleven of the thirteen configurations and $389 for Juniper and Spruce, the two with text-only email. Dumb Wireless matches that at $359 for Aspen and $389 for Juniper, and other resellers list the Pro from about $330. An optional Sunbeam Premium subscription covers voice-to-text, hourly weather and radar, points of interest in navigation and NumberLink. Sunbeam has moved sign-up off the site and does not publish what it costs, and the phone works without it.

Connectivity
- Network
- 3G / 4G3G WCDMA/UMTS on bands 2 and 5, 4G LTE on bands 2, 3, 4, 5, 12, 13, 20 and 71. The big US networks have all switched their 3G off, so calls ride on LTE at home and the 3G radio only really matters when roaming.
- VoLTE
- Yes
- SIM
- Physical SIM + microSDOne nano-SIM (4FF). No eSIM and no dual-SIM slot. There is a microSD slot that takes cards up to 32GB, and Sunbeam sells a 32GB card with map data already on it.
- Wi-Fi hotspot
- YesA hotspot connection is unfiltered, so whatever uses it does its own filtering.
- Bands
- 3G WCDMA/UMTS: B2, B5. 4G LTE: B2, B3, B4, B5, B12, B13, B20, B71. Sunbeam warns the phone will not work in much of Europe, Africa and Asia because it lacks the LTE bands used there.
- Works on
- AT&T, T-Mobile, Verizon
- Carriers
- Unlocked. Works on Verizon, AT&T and T-Mobile in the US and on Bell, Rogers, Telus and Videotron in Canada, along with most of their MVNOs. Sunbeam's own compatibility table marks Safelink, Spectrum, Visible, Xfinity and US Cellular as not working.
- Kosher version
- YesSunbeam builds for observant buyers: every configuration is filtered, and you pick how far.
Where to get one
- Regions
- United States, Canada
- Countries
- Sold to customers in the United States and Canada. Sunbeam's stated policy is North America only, because a warranty claim has to come back to North America; the phone is built for the Americas and lacks the bands needed in much of Europe, Africa and Asia.

Notes
Thirteen software builds differ only in what is switched on, from Oak with no media or camera down to Willow, which is calls and texts. Eight of them block calls and texts to AI numbers. A hotspot connection is unfiltered, so whatever uses it does its own filtering.
