Who made it and what happened

The Cat B40 was made by Bullitt Mobile, which the Cat phones site called the "Manufacturer of Cat® phones," under the Cat (Caterpillar) brand. The specifications on this page come from an archived copy of the official "Technical specifications - Cat B40" page (Cat phones USA), saved by the Internet Archive in July 2024. The live catphones.com site did not load when we checked on Oct. 15, 2026.

That spec page lists the operating system as "Proprietary," a Unisoc T117 chip, a 2.4-inch QVGA screen, a 2 MP camera and a "Super bright 100+ lumens" torch, plus antibacterial protection and a body that can be cleaned with soap and water, alcohol or bleach. [1]

Where to get one now

New units are hard to find. On Oct. 15, 2026:

All three are third-party sellers. We found no new unit listed for sale in the US. [2][3][4]

Will it work in the US?

Very unlikely. The official spec page lists LTE (4G) bands 1, 3, 7, 8, 20 and 28, 3G bands 1, 2, 5 and 8, and GSM bands 2, 3, 5 and 8.

T-Mobile's 4G LTE bands are 5, 4 and 66, plus Extended Range bands 12 and 71; AT&T lists 12/17/29, 5, 2, 4/66 and 30. The Cat B40 has none of these LTE bands. Its 2G and 3G band 2 (1900 MHz) is no help: T-Mobile's network-evolution page says its 3G UMTS network was retired on July 1, 2022 and gives Aug. 3, 2026 as the date its 2G GSM network is retired. AT&T says a phone "has to operate on 4G LTE network" to work on its network. T-Mobile's checker rejects devices that can't use Extended Range LTE, and the FCC notes that phones without VoLTE (Voice over LTE) lose service as older networks shut down. [1][5][6][7][8][9][10]

Apps and Google

No Google apps and no app store. The spec page lists a "Proprietary" operating system. It has Bluetooth 5, a 3.5 mm headphone jack, USB-C and microSD support up to 32 GB. [1]

Questions people ask

Is the Cat B40 still made?

We found no sign that it is still made or sold new. The official catphones.com site did not load when we checked (Oct. 15, 2026), and this page relies on an archived July 2024 copy of its B40 spec page. [1]

Does the Cat B40 work in the US?

Its LTE bands (1, 3, 7, 8, 20, 28) don't include any main US 4G band, so it isn't a practical US phone. [1][5][6]
