Question about Huawei E5770

If the NAS can be reached from the Internet: Yes.
The device does nothing different than a smartphone that you turn into a hotspot.
So if it works via the hotspot from the smartphone, it will most likely also work with this device.

so, i had to search for a long time to find this answer. so you can't connect the 4gmodem to the NAS from outside with any provider in switzerland? So my cable connection can't be cancelled after all. it's a shame, actually, because salt unlimited is currently offered for 10 francs a month.

best thanks for the answer
