What is cryptography behind this to help?

And what will happen if the SMS receiver don't claim their sats within 7 days?

The expiration date for bitcoin is something new.

I suspect that after this period the gift can't be used, that's all, and the money will be returned to the sender, or rather, the recipient will not receive it.

And SMS is a bit unsafe. Bringing Bitcoin to more people should not contain more risk for them.

The more ways to send and receive BTC, the better it will be for the bitcoin network, because it makes the network more viable and ready for any trouble.

Don't worry about the fact that the execution of this idea is not perfect. Look at it as a prototype that will be improved or new alternatives will be invented. We don't know what kind of technology will be able to gain a foothold in the crypto community. The main thing here is to try and look for solutions in the process of which we can get something new and better.

"As a result, Lightning wallet-compatible apps on phones or computers can send Bitcoin over the Lightning Network to the phone’s number—it has effectively become a Lightning address. Machankura has integrated with Bitrefill, an increasingly popular prepaid gift card service for Bitcoin in Africa. Plus, as of Wednesday, South Africans will be able to top up their Lighting Wallets with credit from grocery stores in a partnership with “One for you,” a voucher provider. "

It is good news and in the past also we had service providers of sending BTC via SMS or without internet but it hasn't been that much successful even though bitcoin community is growing everyday. I wonder even in 2022 still we are lack of internet coverage atleast 2G?

If I am not wrong people who have smartphones and experiencing internet is higher than people who are using toilets so we almost have internet everywhere.

It's interesting idea of SMS for sending Bitcoin BUT it can also connect your identity with your Bitcoin addresses, so I would only use this with anon prepaid numbers.
If I understand correctly this is Lightning Network, so it's not directly connected with BTC address, but problem could be that most people probably run custodial LN wallets on their phones.
I hope nobody will arrest him for making this publicly :/

I will still stick to Bitcoin transactions using the normal internet service to process everything including the gas fee.

Don't be too rigid, this innovation may still turn out to be something very useful. What we need to look out for at the moment is the sustainability of this new development, how long will this SMS service permit this sending of btc via text? I'm certain there will be a lot of observers unto that regards, and truly if it proves sustainable, this is another welcome development that will spread quickly to other countries.

Now that is cool. I really like to see innovations like this. It seems more and more bitrefill is partnering with people who want to spread the use of BTC
Since it's LN the fees are negligible and it makes it easy to get people to use BTC without worrying about fees and other things.

Totally caught me off guard as well. Seeing the article headline, I automatically assumed it was solely a centralized database interaction à la like Coinbase<->Coinbase transactions. Well, surprisingly it actually uses LN.

its a hybrid of both.

people WITH smartphones that are internet enabled can go to a retail store, buy a certain giftcard and redeem that for LN msats via bitrefills. and then send them msats to the service.
where the service then uses its central database to credit peoples SMS number in its mysql database with a allotment of sats(custodian) on its centralised database

those using 2g only (GSM) can then send a message to the central service to request transfers of central database balance/custodian to other peoples SMS number

this system is not about setting up a LN channel for every single SMS user. as there is just is not enough liquidity or (i wont mention al other issues) to perform that.

the important thing is the OR in their description of the service. it reveals alot that its not 100% LN nor 100% bitcoin network

Every registered user can send and receive Bitcoin to their phone number from other Machankura users or to their machankura lightning address.

OT Side thought: Bitcointalk really needs a remind me bot because I can see us discussing this for a bit and then forgetting about it but I would like to see how it's going in a few months.

I will still stick to Bitcoin transactions using the normal internet service to process everything including the gas fee. The use of sms to process transaction can be time consuming especially when service provider is having some difficulties in balancing stable network. I have seen most time sending an sms to friends delays or could not go through because of this same network issues. Receiving SMS can be troublesome most times so I don't rely on it.

According to the news, this services integrated with Bitrefill in order to redeem the voucher code. We know, every time there is a time limit on a promotion or gift, what happens if it is not redeemed? yep, it means that voucher is forfeited. Most likely, the BTC that reported send to someone, but not being redeemed, it will return to the gift giver's wallet. of course maybe will deducted for fees.
Here some informations of this services:

Code:

maybe you wanna try, just used the site, or asked to them from twitter if you have other questions

It's actually a great innovation mostly to Africans as some areas are still lacking in the issue of Internet. But the case of sms having to involve the network providers as Third party isn't that a security problem. And what happens when the receive has a slight network issue and the sms is arrives late? Does this innovation has a solution in check for that

Not your keys, not your coins!

I think the idea for this innovation is very great but not sure is it safe. It is like using a third party service like you don't trade directly with your trade partner but you do this via a middle man.

And SMS is a bit unsafe. Bringing Bitcoin to more people should not contain more risk for them.

I think the idea of making Bitcoin more accessible in Africa is a great one, and if people there text but don't use the Internet often, then the SMS version makes sense. I remember a time around 15 years ago when in my country people tended to talk via SMS texts on button-based mobile phones, for instance. Judging from the screenshot in the article, though, I think it's about smartphones.
The service is custodial, so that's a big downside. My other concern would be about safety, as I believe SMS aren't that secure...
