sms4sats works with hold invoices. This means your payment is finalized by our receiving node only when you receive the code, otherwise payment attempt is cancelled and funds return to your wallet in maximum of 20 minutes.I provided the phone number to the service but I did not receive the SMS. Is something not working?
SMS delivery depends on many factors, most of them that are out of our hands. Most activation success rates are around %50* which means you may need to try at least 2 times before finding a number that works and the service successfully sends an SMS to that number.
Good news is that you can try as many times as you like until it works and you will only be charged for the code that is successfully provided to you. All other failed attempts will automatically be refunded to your Lightning wallet.

Unfortunately, it is currently not possible to recall numbers that were previously used. This is a limitation due to our providers. We are working on ways to make this possible in the future.How can I check if others use and like this service?
