USB would allow simple failover for a customer with a Mikrotik router From: Af [mailto:[email protected]] On Behalf Of Eric Kuhnke Sent: Tuesday, March 08, 2016 4:07 PM To: [email protected] Subject: Re: [AFMUG] Anyone using Ting SIM cards for OOB management?
I'm really hoping to avoid USB if at all possible. The wholly integrated HSPA+/LTE modems that have a 100BaseTX ethernet interface are quite expensive, like the basic Opengear model that is $380. USB could work with a raspberry pi2 if absolutely necessary. One of the things I can predict, the SIM card + Ting concept will almost certainly not get a public ipv4 address, it'll be behind some some of cgnat with no ports forwarded, so the raspberry pi2 needs to initiate and maintain a persistent SSH connection or similar tunnel (such as a tcp based openvpn tunnel with unique-per-device static point-to-point keys shared by server and client, in which the pi2 is the client).

For example with HSPA+/LTE modems, to have proper OOB into the routers at a crucial POP. $6/mo per active SIM card is pretty cheap for M2M data SIMs, though the $/MB rate is not the best. But for the application I have in mind it would be console SSH traffic, which is super low bandwidth. https://ting.com/rates For LTE they're an MVNO on AT&T and T-Mobile. Looking at the FAQ they say that the data usage can be limited and monitored on a per-device basis, which could be useful.
