This appears to be the exact issue I was having in another thread APN not being set properly - #18 by jerdung. I’ve tried updating ALESO to 4.17.1 as the update notes addressed APN issues but still ‘APN not found’ despite having override APN. I’ve been reaching out to SierraWireless support but their transition with SEMTECH has made it a little more difficult and I haven’t received any reply.
