@Lazar-Demin
Could you please advise which variant of the Quectel EC25 will be used in the global model?

From the pre-production images available it would seem that you are using EC25-A for the North American model, but I can't reliably determine which one you'll be using for the rest of the world, unless I have missed that item somewhere.

Also, the images location referenced in the Omega2-LTE github repo README doesn't currently exist.

If anyone is interested, here is the product page for the LTE module Quectel LTE Standard EC25 and there are a large number of documents available for download (after registration).
