Drew (Or sircmpwn? Sorry I don't know how you prefer to be called) since I know you're on here, if I may ask:<p>- What provider are you using?<p>- Is it VoLTE that is working, or does it drop down to 3g for calls?<p>- Does SMS work in LTE mode or do you have to drop it down to 3g?<p>I have a Librem 5 birch, and from my experience in rolling my own Android AOSP version, that to get T-mobile to work with VoLTE, SMS/MMS with LTE, or WiFi Calling, you have to install proprietary blobs.<p>EDIT: I should add the Librem 5 Birch has LTE data on T-mobile, but I have to drop to 3G to get SMS and phone call functionality, and MMS is additionally non-functional at all on T-Mobile. Meant to post that for the Librem 5.
