You mentioned in your post the very reason why some/most companies do not go with companies like simcom, quectel, etc. Even though they are capable companies I believe your research has exposed short-comings that don't address your personal requirements. You cannot really go wrong leveraging the history and expertise of Huawei and ZTE. They are very recognizable and respectable companies that large global organizations like to do business with.
having just left the Carrier world I have a different perspective. I have seen a considerable growth in SIMcom units, and they're well behave on the networks. In UK & IE they're well supported by EBV. Unless you have large volumes you won't be doing business with Huawei or ZTE.
Needless to say Cinterion & SW are excellent units but I assume you're looking for something chaeper?
