You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 34.200.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:16, 2 September 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Dobson Cellular Systems, Inc.''' now part of [[AT&T Mobility]], was a wireless telecommunications provider operating in several regions of the United States, including Alaska, Arizona, California, Kansas, Kentucky, Maryland, Michigan, Minnesota, Missouri, New York, Ohio, Oklahoma, Pennsylvania, Texas, Virginia, West Virginia and Wisconsin. Dobson Cellular Systems was a wholly owned subsidiary of '''Dobson Communications Corporation''' based in [[Oklahoma City]]. It was the provider of [[Cellular One]]-branded services in the [[United States]].<ref>((cite web|url=https://journalrecord.com/2007/02/dobson-cellular-to-become-cellular-one/|title=Dobson Cellular to become Cellular One|date=February 20, 2007|accessdate=February 3, 2024|work=[[Journal Record]]))</ref> Dobson operated under the brand name of [[Cellular One]], and provided service on a [[D-AMPS]] and [[GSM]] network.  The company purchased the rights to the Cellular One name from [[Alltel]] in December 2005.

==Corporate history==
<!-- Image with inadequate rationale removed: [[Image:Dobson transition banner.png|325px|thumb|Transition banner used for Dobson/AT&T transition]] -->

Formed in the 1920s, Dobson Communications originally operated a small wireline telephone network in Oklahoma. Over 70 years, Dobson evolved to become the nation's largest independent rural wireless provider to expand operations into 60 markets, following acquisitions over the last 10 years.((Citation needed|date=December 2023))

On June 29, 2007 [[AT&T Inc.]] announced that they had reached an agreement to purchase Dobson Cellular division. The closing price was $2.8B USD or $13 per share. AT&T also agreed to assume the outstanding debt of $2.3B USD.

The sale completed on November 15, 2007, with market transition beginning December 9, 2007. The [[Cellular One]] brand name was sold to Trilogy Partners in February 2008.

The Federal government prevented AT&T from taking certain Dobson markets In Texas, Oklahoma, and Kentucky along the Ohio border and the I-75 corridor, due to the potential monopoly this would create in this area. After placing these markets in a trust for one year, the Kentucky markets were sold to Verizon Wireless in November 2008 with market transition to be completed by November 2009, and the others, TX-10 and OK-5, were sold to affiliates of MTPCS, LLC, which concurrently adopted the [[Cellular One]] brand under a license agreement with Trilogy Partners.

==Network==
Dobson was, for the most part, a rural provider. It claimed to be the largest provider of cellular services in Alaska as well as in Michigan. It was also the exclusive provider of GSM technology in many of its markets and has a few resellers such as [[TracFone]] and smaller [[MVNO]]s in particular states. It also provided voice and data roaming capability for many AT&T and T-Mobile customers. Dobson had recently upgraded a majority of its [[GSM]]/[[GPRS]] towers with an [[Enhanced Data Rates for GSM Evolution|EDGE]] overlay, providing an even faster data rate for their customers.
