Yes at the moment that's the only option, but this project is still in development and balance control and other features will be implemented soon! My system allows the recipient to send their newly acquired bitcoin straight to a public key or another cellphone after 3 confirmations completely offline. Eventually there will be an import private key function so 100% offline usage is achieved. For now you need to get bitcoin onto the deposit address somehow, and that would likely involve a computer transaction, but once it's loaded you can send bitcoin anywhere with cell service. If you receive bitcoins by this method you have no need for internet or a smartphone which I think can help lower the barrier of entry into bitcoin.

So an example of a useful scenario would be if you wanted to buy/sell a local item on Kijiji, in the countryside, and neither party wants to disclose where they live. So they decide to meet up at a public location that may not have an internet connection, the buyer would come prepared with bitcoin loaded on thier deposit address, and when the buyer feels satisfied with the item they would send bitcoin to the sellers phone, the seller can move that bitcoin after 3 confirmations to another phone number or public address completely independent of a need for a smartphone or internet connection.

Multiple transactions can be received before they are sent somewhere, aslong as the datasize of the transaction does not excited the 0.0007 fee.
