This "smart SIM extension" has great potential, because it uses simple SMS technology on non-feature phones. Contrary to the beliefs of some people in the Bitcoin community, 3G infrastructure is not widely available in most African countries (or is extremely costly to connect with) and even the cheapest feature phones are still too expensive compared to the average income in most of Africa.
Hopefully this will be available soon.
ya.ya.yo!
Sending bitcoins through sms has been possible for sometime now, right?
How is this different?
If you're referring to Coinapult SMS service: It's a centralized service. Their service numbers are from UK/Canada - so SMS from other countries will be expensive. (Hidden) fees (conversion rates).
BitSim is a hardware solution. It is decentralized and works worldwide with local SMS pricing. There`s no intermediary central authority involved. No fees besides hardware costs (which will be very low).
ya.ya.yo!
Never heard of BitSim. Sounds amazing to have normal pricing for worldwide communication.
Which is not always good idea imo.
The private key being in their control does not sound very secure.
