I think it was on an episode of Let's Talk Bitcoin that were talking about the impact of feture phones, think old Nokia handsets running a very early version of Symbian. I also think they were talking about Venezulan fisherman using their new feature phones to call the shore to organise getting the fish to market and how this had had a dramatic impact on their lives because it saved time and brought in more money. The next step discussed was if you could actually trade at sea on your way back to shore, landing at the closest port where the fish you had caught had alreay been paid for. An SMS gateway for NEM that would offer something like the M-Pesa in Kenya and wouldn't require hi-tech just medium-tech
