We have >100 AT&T units deployed and about 35 Verizon units and have had virtually no issues with call home via openvpn. All opengear ACM7xxx series.
We are using machine to machine plans from marketplace.att.com. Used to be a great deal, the new plans are still “fair” and better than standard consumer/business prepaid plans. We average around 100MB/mo/device, we could probably improve that with some effort on keepalives etc. We have had coverage issues in some sites but in the colos we are in it has been fine. In colo we usually also take “house” IP due to XC costs blowing out any 3rd parties, and I have done DSL on PSTN XC before, but even in those cases the LTE is still useful particularly for turn up where the colo house ip rarely “just works”.
