Thank you so much for answering! I posted this before signing in, so I can't reply. Looking at the Microsoft website, these are the network stats it gives:
GSM: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz
Data download speed up to pass GSM: 296.0 kbps EGPRS
Speed Maximum upload data via GSM: 236.8 kbps EGPRS
WCDMA: Band 1 (2100 MHz), Band 2 (1900 MHz), Band 5 (850 MHz), Band 8 (900 MHz)
Data download speed up to over WCDMA: 42.2 Mbps (Cat 24)
Speed Maximum upload data via WCDMA: 5.76 Mbps (Cat 6)
Looks like the 3G is covered, but I don't see any of the LTE options you mentioned. This is the dual SIM version. Not sure if that makes a difference.
