What is the most affordable way to get GSM service for the Pebble Core? It looks like it would cost $20 per month to add a "tablet line" to my current mobile plan which is way too much for me.
If you have Google Fi for your main phone (20$/mo + 10$/GB) you can add up to 9 data-only SIMs for 0$/mo + 10$/GB. The per GB is really fair (I think it rounds to the nearest MB and everything left over rolls over to the next month).
