PinePhone Pro Announced
It has a Quectel EG25-G modem.<p>I&#x27;ve not used this particular device, but I have used Quectel GNSS modules, and they&#x27;ve been a surprisingly helpful company to work with. I&#x27;m a nobody, and working with Sony, Trimble, or ublox has been an exercise in frustration; you have to convince a salesperson that you&#x27;re a big company and you can sell thousands of devices in order to just read the datasheet.  This one does have some of the documents locked behind an access request, but in my experience, they&#x27;ve been very generous with those grants.<p>The modem supports the following bands:<p><pre><code>    LTE-FDD: B1&#x2F;B2&#x2F;B3&#x2F;B4&#x2F;B5&#x2F;B7&#x2F;B8&#x2F;B12&#x2F;B13&#x2F;B18&#x2F;B19&#x2F;B20&#x2F;B25&#x2F;B26&#x2F;B28   
    LTE-TDD: B38&#x2F;B39&#x2F;B40&#x2F;B41 
    WCDMA: B1&#x2F;B2&#x2F;B4&#x2F;B5&#x2F;B6&#x2F;B8&#x2F;B19  
    GSM: B2&#x2F;B3&#x2F;B5&#x2F;B8

which is pretty good. Americans will want 4G bands B2, 4, 5, 12, 13, 14, 17, 20, 25, 26, 29, 30, 41, 66, and 71; this implements 9&#x2F;15, it&#x27;s missing bands 14, 17, 29, 30, 66, and 71. Those missing bands are either subsets or supersets of other bands (which could be interesting from a firmware perspective - will a tower with a band 66 antenna give this modem some of the central band 4 subset, or will it try to negotiate a channel that this can&#x27;t access?), little-used ATT bands, or the 600 MHz T-mobile band 71, which has a wide rollout but poor device support.
