"We're always looking for ways to improve and expand our services," said Kevin McDorman, vice president of AT&T's communications finance business operations. "We have customers who use cryptocurrency, and we are happy we can offer them a way to pay their bills with the method they prefer."
BitPay allows customers to "reach new markets instantly," according to AT&T's website. There are also no hidden fees. The system also is aimed at eliminating identity fraud.
AT&T said it was the first major carrier to accept cryptocurrency as a payment option.
Bitcoin has jumped 89% since April 1 when it began its surge after having been flat for most of the year. Bitcoin was trading at $7,843 on Thursday.
