I've been testing the PinePhonee for quite awhile now, but am still having one problem: Is there a trick to placing a phone call? I'm using an image I downloaded last weekend, which I updated, (apt update && apt upgrade), and I'm using T-Mobile, which I hear is a good carrier to use with the PinePhone. I can receive calls, but when I try to place a call, it returns: Call Failed.
Many thanks
