Frequently asked questions
SIN does not accept crypto but Bitrefill provides a workaround that allows you to top up your smartphone with Bitcoin or other cryptocurrencies.
A mobile airtime top-up should be added to a phone number within a few seconds to minutes. Sometimes, there may be a small delay on the part of the mobile operator, but rest assured, we will send you an email confirmation as soon as your top-up has been processed successfully.
Some alternatives that customers consider in USA usually are T-Mobile, AT&T, Verizon, Simple Mobile and H2O PayGo. You can find many other options by visiting the phone refill section on our website.
