[chan_dongle] Which dongle/USB hub to buy?

Hello guys,

I tried chan_dongle with an old dongle that I bought in China few years ago (not exactly sure what brand/type it is but chan_dongle says Huawei E1750 and dc unlocker can’t detect it). SMS works fine but I can’t get calls to work. It looks like I need to unlock voice but the firmware is also very old.

So instead of spending all my time trying to fix this old dongle I was wondering if you guys could recommend me a new dongle? Preferably one that is already unlocked and has voice enabled. I would like to use two of them in my raspi. One dongle works fine in my raspi but I guess for two I’ll need a powered USB hub, any recommendations for that too?

Thanks! :smiley:
