YC Product Documentation
Sunbeam F1 Pro

Overview

The Sunbeam F1 Pro is Sunbeam Wireless’s premium rugged flip phone, built for people who want a dependable communication tool without the distractions of a smartphone. It runs on BasicOS β€” a stripped-down Android 8.1 AOSP fork with no Google services, no app store, and no web browser. What you get is a phone that makes calls, sends texts, and handles a defined set of approved features, nothing more.

The F1 Pro steps up from the F1 Horizon with a larger 2,200 mAh removable battery, a 5 MP rear camera, a full-color 2.8” internal touchscreen, and certified IP68 water and dust resistance alongside MIL-STD-810H military drop standards. It is well-suited for outdoor workers, industrial environments, and anyone who needs a phone that can take a beating without compromising focus.

BasicOS philosophy: No Google Play, no third-party app installs, no browser. Features are enabled or disabled at the model level by Sunbeam Wireless. The phone cannot be β€œunlocked” to add features not included in the purchased model.

  • β—† No app store β€” apps cannot be sideloaded or installed from any source
  • β—† No web browser β€” internet browsing is not available on any model

CategoryDetails

LTE Bands (4G) B2, B4, B5, B12, B13 β€” Cat 4 (download up to 150 Mbps)

Durability

IP68 Rated β€” the F1 Pro is sealed against dust ingress (6) and can withstand submersion in up to 1.5 meters of fresh water for up to 30 minutes (8).

MIL-STD-810H β€” tested to U.S. military standards for shock, vibration, temperature extremes, humidity, and drop resistance.

Important β€” Warranty does not cover water damage. Despite the IP68 rating, water damage is not covered under the Sunbeam Wireless warranty. The IP68 rating is a manufacturer’s test result under controlled conditions; real-world exposure to saltwater, chlorinated water, high-pressure water, or water after physical damage can compromise the seal. Do not intentionally submerge the device.

  • β—† Inspect and reseat the battery cover regularly to maintain the water-resistant seal
  • β—† If the phone gets wet, dry it thoroughly before charging via USB-C (use the charging dock instead)
  • β—† Physical damage to the housing (cracks, dents) can void the IP68 seal

Accessories

Sunbeam Wireless offers a range of accessories for the F1 Pro, including cases, replacement batteries, and charging solutions. Key accessories include:

  • β—† Replacement battery (2,200 mAh β€” F1 Pro specific; not compatible with F1 Horizon)
  • β—† Charging dock (replacement)
  • β—† Protective cases
  • β—† Car charger

Tips & Troubleshooting

Camera: β€œCamera Has Stopped” Error

If the camera app displays a β€œcamera has stopped” error, the most common cause is a corrupt or oversized microSD card.

  • Remove the microSD card and test the camera. If it works without the card, reformat or replace the SD card.
  • If both the camera and the flashlight fail with the SD card removed, the phone likely needs to be replaced.
  • SD cards larger than 32 GB are not recommended β€” they can cause camera errors and other issues.

Group Messages

The maximum number of participants in a group message is limited by the carrier, not by the Sunbeam phone itself.

Transferring Messages to a New Phone

Messages can be transferred between two Sunbeam phones using the built-in Backup tool. This is the fastest and easiest method, and it works even if the old phone has a blank or broken screen. Note: messages cannot be transferred to a different phone brand.

Backup with broken screen: Dial *222587* (*backup*) to start a backup to the microSD card without needing the display. The phone will beep when the backup starts and again when it finishes. A different beep means no SD card was found.

Blocking Numbers

  • Block a call: Dial the number, then select β€œBlock Number.”
  • Block messages: Open the messaging conversation with that number β†’ Menu β†’ Participant options β†’ Block.
  • Contacts-only mode: Contacts β†’ Menu β†’ Settings β†’ β€œAllow incoming calls from Contacts only.” Repeat for messages.

When a blocked caller dials in, the call still appears in the Call Log as [Blocked] so the customer can see who called. Blocked callers can still leave voicemail.

Wi-Fi Calling

Wi-Fi Calling does not work with AT&T or AT&T-based MVNOs (e.g., Selectel). It works with T-Mobile and Verizon-based service, though some MVNOs may not support it.

Email Sent Folder Setup

When setting up email (Gmail, Outlook, Yahoo, etc.), the Sent Items folder is not automatically configured. After adding the account, go to the email app β†’ three-dot menu β†’ Settings β†’ Accounts β†’ your email address β†’ Folders β†’ Sent Folder, and select the correct folder.

Service Codes
