I was browsing Facebook earlier today and saw an advert for ChatSim.
This is being marketed as the low cost sim for use with IMs such as WhatsApp, which for as little as £10 a year, you can use send unlimited text and emoji messages from anywhere in the world.
From what I can gather, this is a bit of a loss leader, with the long term idea being that people will get the sim for messaging, but as most (but not all) phones can only support one sim at a time, they’re hoping to sell extras, such as more advanced messages (images, videos, etc…) and phone calls, etc…
So I was just about to close the window, uninterested in such a thing, until I realised that it could be good for use in IoT projects?
I’m sure there’s something out there which will let you use a sim with an Arduino or Raspberry pi, for reporting back to base, and as long as you’re only sending textual information, this could be a cheap way of achieving that?
Anyway, I’m not that clued up on IoT, so it’s possible what I’ve just described is silly - but I figured I’d post about it here anyway, as I want to hear what you think about? Would something like this be realistic? Or am I way off the mark?
