RPi3 with Huawei E3372 4G modem and DynDNS

Hi all,

I just like ask if i can make a setup like this:

RPi3 as a USB Server and with a Huawei E3372 4G modem so i can get it online on internet.
Then i will install a USBtoRS232 on the RPi3 that i like to mount to my PC and use my local software.

I do have RPi3 and the Huawei E3372 4G modem ready.

Just need to sign up a account for DynDNS or?
Dynamic DNS Service can i use: www.ddns.net

Will it be possible to make a stable system?
Can i make a test to see if this setup will work for me or do i need to buy license first?

You can test this setup without purchase. However you need to make sure your 4G network has low latency as the serial data needs a stable latency. I.e if your 4G network connection has variable and large latency (ping time) the serial transmission probably wont work. If its low and stable (take a look in the About -> Statistics page of the virtualhere client) it should be ok
