What libqmi version, and what does !GSTATUS? report as the active band? If it's EUTRAN-28 then perhaps your libqmi is too old; that band was added to the list in libqmi 1.20 in late 2017. But that was a long time ago and I'd assume you are using something newer than that. (commit 780abd945a55f9) However, I don't see another quick reason why you'd get (null) there when the value is clearly passed back to libqmi but not interpreted correctly.
