This is a standard sized SIM card with 6 months of unlimited data-only use. Service for this SIM card provided from T-Mobile through SparkFun and works in any T-Mobile coverage area in the world! No contract, no credit check, no strings attached. This card is specifically meant for M2M (machine to machine) communication. It is not intended to be used in phones, tablets, or hot spots and will not work in those devices. Compatibility will vary by device. You get 1GB per month at full LTE speeds (once that 1GB limit has been reached you will be throttled). Each card will have activation requested when it ships. Activation can take 1-3 business days to process through T-Mobile.

To be completely honest with you, we are carrying this data-only SIM so that you can get up and running with your cellular development quickly and without having to go to your local phone store and try to explain why you need a data-only SIM for your tweeting cat door.
