You can find them at: http://www.hologram.io/ <http://www.hologram.io/> It is most likely that OVMS v3 will come with Hologram.IO SIMs and we will use these as our default cellular provider, worldwide. Zone 1 pricing (including USA) for a 3MB plan is U$1.99/month, and the 5MB plan is US$2.99/month - that amount of data should be fine for normal OVMS usage. Overage is US$1/MB. Alternatively, you can pay-as-you go at US$0.40/month for the SIM connection, then US$0.60/MB. This is really designed for data usage, but SMS is available at a price. Incoming SMS is free, and outgoing is US$0.19/message. If you want a fixed USA number, it is another US$1/month. To migrate an existing OVMS module to this, you SMS "GPRS hologram" to the module while it is still connected to the network using your old SIM. When the acknowledgement comes back, turn off the module, switch in the Hologram SIM, turn on and enjoy. The SIM will seamlessly switch to whatever cellular network it supports. It can even roam (although Canada and Mexico are zone 2 so you would need to pay the higher rates). If your existing OVMS is offline, you can provision it using the Hologram web console. There is a facility there to send an SMS message to the module, and view the reply messages online. If anybody wants to try this out, please let me know and I'll make the necessary arrangements.
