T-Mobile and AT&T have put aside any differences they may have and are teaming up in the wake of damage caused by Hurricane Sandy. They are taking extraordinary measures to make sure their customers are able to stay in touch with work, family and friends.
Both companies have entered into an agreement to enable roaming on their networks to customers of both companies in the heavily impacted areas cellular service has been dramatically impacted.
While 911 calls will always be carried by the first available carrier your device finds completing other calls require access to the competitors network.
What this means to you:
Customers will be able to place calls just as they normally would, but their calls will be carried by whichever network is most operational in their area.
This will be seamless for AT&T and T-Mobile customers and you will not incur any additional charges for making a call while roaming on the other carriers network.
T-Mobile and AT&T both utilize network technology based on GSM and UMTS standards, which allows for this easy sharing of voice and data traffic.
