US operators AT&T and T-Mobile USA have allowed customers  heavily impacted by Hurricane Sandy this week to roam across their networks where capacity is available, in order to ensure they can stay in touch during the natural disaster.

AT&T and T-Mobile customers will be able to place calls just as they usually would, but their calls will be carried by whichever network is most operational in their area.

The operators said in a joint statement that their customers will see no change to their current rate plans or service agreements, even if the phone indicates the device is attached to the other carrier’s network.
