Unfortunately, this router with diverse and widespread USB modem does not work (I myself have the Huawei E1552, Huawei E173 and ZTE MF112 tried). None of work and there are unfortunately no Kompatipilitätsliste the manufacturer or the network. 3G can thus write off man! In support requests via email Technaxx not answered. I use the device as an additional AP for my existing DSL router .... it works at least - but can not indeed be the purpose of the product ..... a pity!
