Cat S75
The last phone Bullitt Group released under the Caterpillar licence, launched at MWC in early 2023. It was one of the first consumer phones anywhere with two-way satellite messaging built in, not just emergency SOS but ordinary texting off-grid.
Bullitt closed in January 2024 and the phone is discontinued. The satellite service is not.

Satellite messaging, and whether it still runs
It still runs. This is the question everyone asks, and the answer usually surprises them.
Bullitt Satellite Connect was sold to RCD 2023 Ltd, trading as RCD Bullitt, in February 2024, weeks after Bullitt Group’s collapse. The service has operated continuously since, still sells subscription plans, and the company was launching new satellite hardware at MWC as recently as 2026.
What it does: two-way text messaging and SOS with no cellular coverage at all. The phone reaches geostationary satellites over a non-terrestrial network, and you send and receive through a companion app. Recipients need no special hardware; they get a normal message with a link to reply.
What it does not do: voice calls. There is no satellite calling on the S75 and there never was.
What it needs: a clear view of the sky roughly toward the satellite, and patience. Messages take longer than cellular texts, because this is a low-bandwidth link rather than a data connection. It requires an active subscription.
Check current plan availability for your country with RCD Bullitt before buying an S75 for this feature, since a different company now runs it.
The rest of the phone
Strip away the satellite feature and the S75 is the most conventional phone Cat ever made. A 6.6-inch 120 Hz screen, 50 MP main camera, 5G, wireless charging and Gorilla Glass Victus put it in ordinary mid-range smartphone territory. It just weighs more and has thicker walls.
The Dimensity 930 runs everyday apps smoothly and is not a gaming chip. The 50 MP main camera is decent in good light; the 8 MP ultrawide and 2 MP macro pad the spec sheet more than they get used.
IP68 and IP69K, so pressure washing is survivable. MIL-STD-810H drop and vibration testing, which is a manufacturer-run methodology rather than a third-party certificate. Android 13 is final, with no further security patches.
Should you buy one?
Yes if you want satellite messaging and the alternatives don’t fit. Apple and Google now ship satellite features on mainstream handsets, but coverage, plan terms and device requirements vary a lot by country, and the S75’s implementation is not tied to a carrier.
Yes if you want a rugged 5G phone at a used-market price and accept no warranty and no updates.
No if you want a current, supported phone.
Before buying, verify the satellite subscription situation for your country, check the battery (the 5,000 mAh cell is sealed and not user-replaceable) and confirm the port covers are intact. It is worth knowing what the S75 sells for now and whether your carrier will activate it. There is no manufacturer warranty behind any of it. Why the brand stopped
Cat S75 or Cat S53?
Both are 5G. The S75 has a sharper 120 Hz screen, a much better camera, Gorilla Glass Victus, satellite messaging and a newer chip. The S53 has a bigger 5,500 mAh battery and usually costs less. If you don’t need satellite, the S53 is the value pick.
