Thanks friend 💪. I know about them yes, I should have added in the note internet or cellular, my mistake

I actually tested it as well a while back and put about 1000 sats on my phone's sim card. It's pretty awesome and in africa it's a game changer in my opinion, because of so many people that still operate with "dumb" phones that can only call and send sms but no internet

Not sure yet how you would use it at a major retailer but very easy for any peer to peer transactions using only a cellular connection
