Wireless giants T-Mobile and AT&T have come together, at least temporarily, for the benefit of customers affected by Hurricane Sandy. The storm which hit the northern east coast earlier this week has knocked out power and caused untold amounts of damage. People have been stuck at home by streets being flooded, with nothing to do as they have no internet, power, or cell service.
This is where the partnership comes in. AT&T and T-Mobile have agreed to share networks temporarily so that users will be able to get more cell coverage in the affected areas. Since many of the cell towers of both networks have been affected by the storm, this is definitely a good move by the companies to create good will.
It's also just a really compassionate thing to do. It's great that the two companies use similar technology as it allows them to basically flip a switch at the main office to allow this roaming. Users will not have to do anything to make this happen and should be able to just reap the benefits of the expanded network.
