I have a new Xiaomi Mi 5C ordered from AliExpress. When connected to the data network in Denmark, the internet is horribly sluggish. It seems to only be able to connect via Edge. Anybody knows a solution?
Note 1: that the same sim card in another phone provides 3G connectivity.
Note 2: all the settings are such that it should be using 3G when possible (e.g. Preferred Network Type = 3G)
Android Version: 7.1.2.
