- SMS is completely portable across the world, which is particularly important in developing countries where the majority of consumers cannot afford fancy smart phones.
- It’s quite easy to get ubiquitous access via SMS to devices because of (a) SMS aggregators and (b) email interfaces to SMS.
Personally, I’m a big fan of SMS and it has played a role in the two mobile startups I’ve worked with. I take many Facebook actions through SMS. It’s much more efficient that logging in to the web site. I’d use it for Twitter also if there was a smarter way to reduce the volume of messages. One of the great benefits of SMS is that it is not that widely used and hence there is a lot less clutter there than on email.
