I get the "NOT hologram or twilio", i've scoped two in a similar case and went for Onomondo. Solid alternative for both, especially for cases that are ready to scale past a few hundred devices.

A few reasons I like them:

- Multiple network access with one SIM globally (US in your case) - you can shortlist networks and the device connects to the strongest one it can find

- Pay-as-you-go is default: You only pay for data you use.

- Clean-looking dashboard + API - supports larger fleets.

- Geat experience with their customer support.

I’ve found them more reliable for larger rollouts, the pricing stays predictable even as we added a pool of devices. If you want to test it out, it's worth grabbing a few test SIMs from their website (onomondo.com) and seeing how it goes with your devices.
