I’ve griped plenty in the past about the wireless situation in the USA, where each carrier uses completely different LTE bands, so no universal USB modems exist. But here’s a secret: The Comrex Connect modem designed for International use includes virtually every LTE band in use in the USA.
What’s the catch? If you go to your favorite carrier (at least Verizon and AT&T) and try to get them to register this modem, they won’t be able to help you. The model is not in their database because it hasn’t gone through their crazy tedious and expensive certification process. This is why we offer Comrex Connect modems specifically for Verizon and AT&T networks that carry these certifications.
Now, I’m not saying you should take a pre-registered data SIM and use it in the International Connect modem. I would never say that. I’m just saying that technically, this seems to work in our testing. And technically, this creates a scenario where you can simply move any convenient SIM card from any carrier (except probably Sprint, who put the kibosh on such things) worldwide into the modem, and off you go.
