AT&T has concluded the purchase of mobile network Alltel's assets in the American state of Utah, previously owned by Verizon Wireless.
Over time, Alltel customers across 18 counties in the state will be moved to the AT&T network, according to AT&T spokesperson, Brooke Burgess.
Burgess assured customers that it would take about one year to convert Alltel's infrastructure to work with the AT&T network.
She stated: "During those 12 months, those customers won’t see any changes. There are no changes to their phone numbers, rate plans, network coverage, customer service contracts or the process for making monthly bill payments."
Alltel was acquired by Verizon Wireless in 2008, but competition regulators forced Verizon to agree the sale of certain Alltel assets in order to gain regulatory approval for the takeover.
Verizon Wireless spokesperson Bob Kelley explained that the switch would not affect existing Verizon Wireless customers.
Kelley said: "If you are a Verizon Wireless customer now, this has no effect on you at all. If you are an Alltel customer, you will become an AT&T customer."
