LTE / 5G USB solution for global use

Hi @ everyone,
I am searching a USB Dongle that supports mobile internet which can be used globally.
All devices I own are either based on Huawei or ZTE which cannot be used in the US anymore.
So I would like to have a recommendation what I can use instead.
I don't need ultra high speed but need to have a fail safe solution if there is no internet and I need to access my OpenWrt devices remotely...

Untrue, unless the equipment/connection/network is owned by the US Government (also - any States that have the restriction too). The restriction is for official equipment and official use.

The only other restriction is on carrier-installed equipment.

It's America my friend, feel free to use whatever compatible equipment you desire.
