Yes, as a rule, you can also use the card in a router. The subscription runs on the Sunrise 3G, 4G/LTE, and 5G network and is also described by Digitec for LTE and 5G routers. Please note, however: This subscription only offers 0.4 Mbit/s. For router use, this is usually only suitable for very simple applications, not for normal browsing or streaming.
