If you do get a SXT LTE, you really want to set the band to 3, its the 1800Mhz, this band has so much more throughput, especially where I am and I can only get the good speeds on that band, if its on the other band Three have (band 20 800Mhz), I get quarter of the speed with the thing in exactly the same place, even though the signal is better.
It was trying to do this that I found the web interface for the SXT, the band selection didnt work, what you need is the Mikrotik "Winbox" software (from their website), connect to the SXT default 192.168.88.1, no password (this can be set to something a bit more secure!)
On the left of the app window click Interfaces, then double click the lte1 interface (in the now open new window), and this opens a new window which will does allow you to change band and network mode etc, and with this it does work. Oh and before all this you need to enter the apn "3internet", that does work from the web interface or quick set screen.
