The 7260 chipset is also specific to LTE network connectivity
Please check this article The number of bands has more than doubled over the XMM 7160, to over 30. This makes the XMM 7260 a truly global LTE-Advanced solution, having support for every band used in every country that uses LTE. Moreover, up to 22 of these bands can be used simultaneously, meaning that switching between bands should be seamless, which is a key factor for globetrotters. There's no more need for one device per region/provider.
Anyway, I agree it's difficult to speculate further at this stage about the Glassware chipset
