Question about Huawei E6878-370 5G Hotspot Mobile WiFi Pro (8000 mAh)

So, according to Wikipedia: https://en.wikipedia.org/wiki... use

Salt N78 / N75
Sunrise (N28) / N78 / N80
Swisscom (N1?) / N78 /

According to @patrick.koehler's article, the thing at least supports N78.

So all providers should be covered. Swisscom's N1 network is part of the old 3G network (2100 MHz) and, at least for me, a 5G sham, since it can never reach the speed that 5G actually allows, so it can be ignored since it is probably just as fast as 4G.

So not Swisscom network compatible?
