T-Mobile customers in locations around the world reported problems with international roaming over the weekend.

The wireless carrier’s customer service Twitter account responded to one inquiry on Saturday with an acknowledgement that the company was “experiencing an outage,” according to unofficial blog TmoNews.

The blog noted that the outage lasted several hours but that service was later restored. Customers in several European countries, along with Israel, Colombia and Singapore, indicated problems during the outage on Twitter or Reddit.
