Since the devastation caused by Hurricane Sandy, there has been spots where AT&T and T-Mobile customers may not be able to get services. In the wake of this, phone towers have been heavily damaged or destroyed. The two biggest GSM telecoms have decided to join forces to make sure their customers are able to utilize their services whether they use their services or roam into the other.
I think this is a great thing to see from competitors and shows anyone can come together. Also looks like it shows the work that may of happened if they had ended up merging together.
AT&T and T-Mobile Open Networks
to Customers of Both Carriers in New York and New Jersey
Dallas and Bellevue, Wash. — October 31, 2012 — In the wake of destruction caused by Hurricane Sandy, AT&T and T-Mobile are taking extraordinary measures to make sure our customers can stay in touch.
AT&T and T-Mobile have entered into an agreement to enable roaming on their networks to customers of both companies in the heavily impacted areas and where capacity is available and for subscribers with a compatible device.
AT&T and T-Mobile 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 with 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.
T-Mobile and AT&T both utilize network technology based on GSM and UMTS standards, which allows for this sharing of voice and data traffic.
