AT&T, Verizon, and T-Mobile customers can’t use international roaming

Phone customers with the three major US carriers — AT&T, Verizon, and T-Mobile — are finding themselves unable to use international roaming, even to make simple calls, according to The Verge. As of June 27 the issue has been ongoing for over a day, with complaints reportedly spreading across social media. The carriers were initially slow to respond as well, but two of them are now blaming an issue with a third-party vendor.
