Yes, it is possible with StealthText to transfer money without internet.
Here is a proof:

Another video where the money transfer is made in USA:
https://www.youtube.com/watch?v=MrM5IjL5Zh8Currently StealthText tech is for tech-savvy people. It needs to be simplified to be user friendly.
No other coin has such feature.
Afaik VRC has the feature to send money through SMS but it`s a centralized service unlike XST. I`m not sure either if VRC`s SMS service is anonymous.
That feature looks very impressive. I want to send it to myself for test. All i need to do the same what on video is StealthWallet, StealthText application and some StealthCoins?
Video was little bit blury, how much minimum coins i need for sending sms?
Also i like encrypted anonymous SMS services

What you need are: StealthClient, StealthText, StealthRelay and StealthCoins.
All the relevant links to these apps are included in the OP:
https://bitcointalk.org/index.php?topic=836009.msg9342300#msg9342300StealthRelay package also includes instructions on how to set up a pipeline and send XST with a decentralized SMS. You may also need a google voice number, but to my understanding there`s also other way to send XST without internet and google voice number (as in case of that Iranian guy).
There is no minimum XST required to send through StealthText. You can even send 1 XST.
If you manage to set up a StealthText service, PM me your XST address and I`ll send you 100 XST for free for testing purposes.
