You would rather check that the chip is certified for what you need before you buy. > also you need to work on getting yourself provisioned correctly in the mobile networks AFAIK also, this is a service provided by "virtual operators", companies that pass deals with the main operators and provide advanced services for machine-to-machine uses, for instance.

Yeah, this is all true in my experience. We buy devices with the appropriate Quectel modem for the region, stick a SIM card in from a provider who has relationships with operators worldwide, then ship it to site. Once it gets given some power the device will connect to whatever mobile network has best signal and call home - we don't actually do a lot of international deployments but even within the country it's hugely useful to have SIMs that will happily roam between all the major operators.
