Phone not reading sim

[arzach]

I got a micro sim, from the store, put it in, and restart the phone. The phone still says sim locked, and when I go into settings, it says no sim card installed. What should I do? UPDATE: It now says modem not available

what distro are you using?

Manjaro, the one that came preloaded.

This might seem like a stupid suggestion, but try flipping the modem dip switch off and then back on and then reboot.
