Users can access Machankura by dialing a USSD code which varies per country. When you dial the number for the first time, a bitcoin wallet that is tied to your phone number is instantly created for you. You are required to create a PIN that will encrypt your wallet and will also be used to confirm all future transactions on Machankura.

Once your wallet has been created, a lightning address is generated for you using your phone number. For example: 256234567890@8333.mobi. You can also change this to a username of your choice e.g machankura@8333.mobi. Anyone can send you bitcoin on this lightning address. You can also send bitcoin to any user’s address.

Tollgate is bitcoin-enabled hotspot (captive portal, payment required) software. To receive payment for bandwidth they use CashU. This works as the sender doesn't need to be online, and Tollgate can lock the payment once received as it is online.

Stackers are crying out for a tutorial

I think there's Blockstream satellite but there must very few people using it.

sending satscards by mail woks too; honestly, trading a pre-loaded satscard for a large purchase (with additional sats or sats-back via lightning) wud be more economical in high-fee environments;

Not yet, but I am interested in using ecash, cashu offline.

Cool idea. There's this - https://bitcoinmagazine.com/guides/how-to-run-a-bitcoin-node-from-satellite

Would be fun to hear from people who've done it. I didn't find out much online.

Soon it will become even more common than it is now.
