I have been using AT&T SIM cards with the Sierra MC7354 in BaseBox units and a few wAP R units with success. Mostly used as "fail-over", but in some cases, the primary internet source for the location.

I have had several clients request Verizon because they already have corporate accounts. I tried a Verizon SIM with the MC7354, but it suffered from disconnects every 15-30 seconds. I tried a lot of changes (as detailed in this post: viewtopic.php?t=97761), but never got it stable.

Then I started to think, maybe I am using the wrong devices/cards. Does anyone in the US have success with Verizon in a Mikrotik using a PCIe card? I have seen some posts discussing connecting an external Verizon USB modem to a Mikrotik, but I need a self-contained and weatherproof option.

Your input is appreciated!
