Hi,
frankly, we can not yet say for sure since this depends on the final hardware choices. We have different possible candidates for the mobile modem and need to negotiate their requirement with the manufacturers now. We will soon have to plan a big visiting tour to different manufacturers and negotiate their capabilities, requirement and sources with what we have on our wish list. We also have to keep power and space constraints in mind. The different modems we have have different capabilities but also pretty different sizes, power requirements etc. And finally they are different in terms of possible freedom we might be able to squeeze out of them. Some are completely closed, some are a little open.
So, we can not say anything definitive yet, sorry.
But we are trying to support as many bands and carriers as we can. But we will not be able to support all, that’s for sure. Best for you is to choose a carrier that does not require proprietary extension or blessings (e.g. I am living in Germany and I am always amazed how much power carriers in the USA still have… here in Germany this kind of monopoly has been broken many years ago so here it is just a matter of technology and not of a firmware support a special carrier).
Cheers
