Interruption in international roaming service for some American telecommunications companies

A major outage in international roaming service is causing the loss of cell phone connectivity for Americans around the world, and the problem affects the three major companies in the United States, AT&T, T-Mobile, and Verizon, with some speculating that the problem may have been caused by an error that occurred while working to change the way they support... Carriers have outdated data standards, according to 9to5mac.

Some users on Reddit reported that their service was completely down, while others described intermittent issues where data service would come and go.

Users who have contacted support are being told that the issue is expected to be resolved within 24 hours, and some suggest that the issue is likely caused by changes made to the way networks support 2G and 3G, and that this is causing issues with rolling back 4G and 5G services.

Syniverse, which works with telecom companies to help make this shift, noted this work earlier this week.

Currently, mobile network operators are retiring 2G and 3G networks to reclaim portions of the wireless spectrum and avoid allocating resources to costly maintenance. However, the operator must fully support VoLTE services before shutting down these networks so that subscribers can stay connected while roaming. .
