I’d like to see a store that sells the components to the kits in your Kickstarter. In particular, I’d like the option to get more E303 USB modems with “HiLink” for Raspberries I already own.
In general, It would be good to note which solutions will continue to work as 2G networks are phased out. I know the E303 uses 3G, but I have some doubts that it may use 2G services to set up the connection (at least when using an AT&T GoPhone sim). You have indicated that the Dash and Dash Pro are 3G. I think the SIM900 on the Arduino kit is a very advanced 2G modem, so an Arduino shield with one of the modems you use on the Dash may be a good addition to your lineup… I suppose with the small amounts of data involved in M2M, there probably isn’t much to say about 4G.
I’ve seen your latest spreadsheet on the plans you offer, and $0.40/month+$0.60/meg is about what you promised in the Kickstarter. It would be nice if you added some discounts for larger data purchases so that 100meg would be more like the $12.50 of the “tariff” plan (what ever that is) rather than $60.00 that 100 * $0.60 would imply. Still need details! If I buy 6 months and 6 meg, do I end up with a sim about like the starter sim you offered on Kickstarter; that is, use the 6 meg any time during the 6 months? Is the data pooled among all the cards on my account, or do I specify the card to credit when I buy the data?
Maybe you could do a blog article some time on how you buy data from your supplier and what limits that places on the plans you can offer. For example, it does seem to be standard practice across the industry to never allow reuse of a sim once it goes off the network, but provisions for test data seem to be all over the place.
