Constantly disconnected, subsequent reconnects

Hi, My device is repeatedly disconnected (as a result reconnects only to be disconnected again).
Checking ifconfig, it appears to gain and then loose a an IP. The log confirms this, as it is immediately disconnected after gaining a lease.
I’m using Verizon Visible, and a Quectel EC25-AF with the LTE Base HAT.
