Hello, yes I bought the sen router and have installed a second Sunrise SIM card. Works perfectly, easy configuration via APP or web interface. I use the 5G router as a mobile internet connection in a holiday flat. 55" TV, Netflix, surfing etc. also runs perfectly via this router. Has got stuck twice in 8 months. Power off/on and OK again.

I got an additional SIM card from Sunrise and have been surfing with it for almost 1.5 years. Streaming on the laptop works without any problems. Configuring the router is sometimes a bit tedious as you have to switch between the WLAN networks. I had configured a daily restart at 03:00 and then a total failure after just under a year. The device no longer went online and could not be reset. Due to the warranty, it was replaced immediately and has been running smoothly ever since - without the nightly restart ;-)

no unfortunately friendship jo
