few days ago had the pleasure to setup 'SXT 4G kit' device, ROS 6.44.6.
Installed two SIM cards (from different operators).
After speed testing:
Operator Tele2, band 7, 2850 - download/upload speed pretty normal, in rage of 80/40Mbps
Operator Telia, band 7, 3050 - download speed is bad, about 5-6Mbps, upload speed pretty normal, about 40Mbps.
Upgraded modem firmware to latest version - still same results.
In same location I put same SIM's to my phone - in both cases got acceptable speed, about 80/40Mbps.
Does anybody could explain why 'SXT 4G kit' download speed depends from operator in the same band? Is that possible?
