Hello, in my company we successfully used Huawei E3372h-153 to connect several remote sites via UMTS+IPSec to HQ: the hilink mode works well, despite it's "minimum functionality"
In past, I've tried myself other models (like E3372h-320) with no success.
THe problem is that nowadays the -153 model is no more available on the market.
Before trying again with the (newer I think) -320 mode, I would like to explore the market to find out another UMTS key that can work with Mikrotik. I read the page https://wiki.mikrotik.com/wiki/Manual:Peripherals but before starting the search on Amazon, I'd like to investigate in the forum if someone knows a well-working USB UMTS in the price range of 50/60 euros available via Amazon in the EU region (I'm operating in Italy).
Thanks in advance for sharing your experience
