ALLTEL Virtually all of the remaining Alltel network in the state has been purchased by AT&T. Other parts of the Alltel network have been sold to ATN which will continue to use the Alltel name, and Verizon Wireless. The transition to AT&T will occur through Summer, 2011 as it launches service on a market-by-market basis. For now, there will be no changes to customers' phone numbers, rate plans, network coverage, customer service contacts or bill payments. AT&T reports that during the network integration, customers will be able to get GSM devices comparable to their existing device at no additional cost. Customers will be notified of any changes to their account and service. Eventually, you will be assigned a new AT&T plan and offered a new AT&T GSM phone which will be use the AT&T GSM network, some of which will be using different cell sites, which may affect coverage,especially while roaming. While there is some uncertainty in a transition like this, previous changes to AT&T have gone smoothly. Your local coverage should not change, and you will eventually be able to use AT&T's entire network and features, including the iPhone. The Alltel network had excellent coverage and reliable data service and under AT&T we expect that to improve. Follow the changes on the Mountain Wireless News Blog.

AT&T
AT&T is what was once Cingular, which was part of SBC, which took over AT&T Wireless and took AT&T's name. They have a large GSM network, but in the west, have a lot less developed spectrum than in the rest of the country. That is changing with AT&T's acquisition of Alltel Wireless in 76 markets in the western US. They claim that their Alltel purchases will all be converted to 3G GSM by July, 2011. Parts of the Alltel network already provide GSM coverage. Other areas will be converted on a market-by-market basis. With GSM technology, AT&T will roam more readily internationally, but there are areas in the US with no GSM coverage. AT&T's takeover of several cellular networks has improved their service in some areas already, including Alaska. AT&T offers a good selection of GSM phones including the Apple iPhone. Parts of what was the old AT&T Wireless network in the interior west is still not among the best. They still suffer from some coverage 'holes', but they are updating some of these areas. Most improvements will be made in the "new" markets and increasing data capacity instead of adding cell sites in older areas. In several markets where AT&T operates at 1900 MHz only, we have been disappointed, but not all AT&T 1900 MHz-only markets are equal. AT&T offers a variety of plans including Unlimited minutes and services, and 'calling circle' plans. They have extensive data coverage. One of their greatest assets is also their worst problem: the overwhelming success of the Apple iPhone that mostly uses the AT&T network. It has overloaded their system resulting in dropped calls, interrupted data and slower service.

Pros: AT&T has a large network and covers much of the nation, usage is transparent whether on- or off-network, good digital and data services, good national plans, "Rollover" for those who can use it, "Unlimited" calling plans available, a good selection of phones. Improvements in coverage have been substantial in some areas, lacking in others. Excellent international roaming capabilities, and AT&T will now supply the unlock code for all phones, except the iPhone, after 3 to 10 months. Additions of Alltel, Unicel and Centennial network purchases give AT&T substantial rural coverage improvements.
Cons: AT&T plans aren't as generous as some, customers can only access GSM networks which are not as universally available in the US as CDMA, customer service varies from above to below average, some markets have a large number of dropped calls caused by large data users.

BLANCA TELEPHONE WIRELESS
Based in Alamosa, Colorado, Blanca is part of the local telco, Blanca Telephone Company. They have good coverage in Costilla and Conejos Counties. If you had a home in their service area, using Blanca Wireless would be an excellent substitute for wireline service, at the same price. The phone would also work outside of the home area, mostly roaming on Verizon Wireless. You could sign up for their local service, but you could roam on them for free if you sign up for a Verizon plan in any other city in the area, like Alamosa or Pueblo. While their network is all digital, they still support analog and "bag" phones from other sources. You can program your existing phone's 2nd "NAM" to Blanca's network. They offer some "bundles" packaged with other communications services. Pros: Small means good, personal service, the only plan they offer is for unlimited local service for about $20 per month. The phone will work nationally. Cons: They don't offer any fancy features, just the basics. Limited phone choices. Roaming fees, while reasonable, are not predictable, they are extra, charged by the minute, and the rate depends on the roaming carrier.

CRICKET
Cricket offers Unlimited wireless usage for one price, but coverage may be a little spotty. For the price, it may work well for you or your family. They have a variety of plans. With Unlimited usage, the circuits may become overloaded. All plans now feature "Nationwide" service through roaming partners, which includes Unlimited Talk & Text. Roaming partners include most of the Sprint CDMA network. Cricket is the largest "Unlimited' carrier and is adding many new markets of their own. You can use Cricket to replace a home wireline. Plans start as low as $30 ($25 in some markets) with Family plans starting at $95 for 3 lines. Cricket also offers reasonable Unlimited Broadband access which is currently limited to their own markets, and supplies a simple USB modem that plugs in to your laptop.
Pros: Talk as much as you want, no contract, most data & digital services are included, good Broadband service, Unlimited coverage now includes all US metro markets. Cons: You must pre-pay, "unlimited" broadband is limited to Cricket markets, off-network roaming is available at an extra charge, some dropped calls when circuits are busy.

NEXTEL
Nextel is a of part Sprint and in some offers, Sprint hides Nextel's features. The combo has allowed the two networks to start sharing cell sites to improve coverage. Nextel's spectrum is made up from a bunch of 2-way radio channels, and they suffer from marginal audio in some markets. Their coverage is more robust in certain areas than others. They cover urban areas and some interstates, but there is little roaming elsewhere in the state. They have an efficient '2-way' radio feature which is handy for businesses and families who want to contact each other as quickly as possible. Some of their plans aren't very competitive, but they do offer free incoming calls. They use 850 MHz so they have a strong signal in most areas. Sprint has announced they are not improving or expanding the Nextel network. Boost Mobile uses the Nextel network and it a good option for Unlimited Voice and Text. Rumors come up from time to time that Sprint wants to sell off the Nextel network, which may or may not include Nextel customers.
Pros: The Direct Connect is a handy 'walkie-talkie' service, robust coverage within their service area. Cons: Some markets have poor audio, they also have coverage limits and very limited roaming, most of their phones are big and lack variety, Nextel does not have fast broadband features, neither the network nor the coverage are being upgraded. Sprint has not treated Nextel customers as well as those using the Sprint network.

SPRINT
Sprint has a national, feature-rich digital network. Their coverage is a little "fragile", but where it's good, it's very good. Sprint has a good selection of phones. Their plans include the ability to roam in many systems when away from their own coverage, as well as any National plan. They offer an inexpensive "basic" plan for only $30 per month. They also offer a few Unlimited plans with lots of features included. Sprint has added service by taking over parts of some carriers' networks, and "sharing" spectrum with others. Sprint merged with Nextel which has created some beneficial network configurations, including sharing of cell sites. Sprint phones normally prefer the network which, where available, gives Sprint customers the best data throughput. Some Sprint phones have the ability to force the phone to "Roam Only", helping you use the strongest network, however there is a limit to how much roaming you can do, generally 50%. Also, newer phones lack that feature. Sprint does not offer their own branded prepaid service but owns Boost Mobile and Virgin Mobile prepaid. Pros: Sprint gives you good value for your money, but is not necessarily the cheapest. Sprint covers every urban area in the US, maintains local stores, good roaming capabilities, their digital and data features work very well, they have a good selection of phones. Sprint has good roaming agreements. Cons: You might find a weak area right where you want coverage, some of their plans are not very competitive, customer service is a notch below average.

VERIZON WIRELESS
Verizon is the largest cellular carrier in the US. They have taken over a large portion of the Alltel network and are now dominant in rural America. Cellular service in a few of Alltel's local markets are being sold to other companies, but no Verizon coverage will be lost. Their claim to fame is superior coverage, especially in the west. They use PCS frequencies only in a few areas, but they have constructed those networks well. In the few places where they don't have their own coverage, they have roaming agreements with other carriers, normally ones with superior coverage. Therefore, their "National" plans, which include almost all of the country, are about as close to "wall-to-wall" as you can get. Their reasonably-priced plans have no roaming or long distance charges, and they also throw in Unlimited Night and Weekend minutes as well as Unlimited calls among Verizon Wireless users both on and off their own network (there are a few exceptions). They offer fairly competitive prices, and often have promotions. They also offer plans that include Unlimited Voice and other features at various fixed price levels. Data service is excellent with various price plans. Verizon forces their phone manufacturers to offer a "standardized" user interface, limiting menu and font variations. This could mean the screen appearance may not be to your liking or the fonts may be too small. Smart and data-type phones require a per-Mb plan. They have the largest area of 3G coverage in the US.

Pros: Verizon has reasonably-priced plans, "Unlimited" calling plans available, extensive coverage, wide-ranging National plans, excellent customer service and 'customer-friendly' policies. With such a large coverage area of their own little roaming is necessary, but their roaming partners normally have superior coverage. Cons: Some Verizon plans are a little more expensive, Customer Service closes at 11pm, but technical assistance is available 24/7, there are some billing transition concerns as they take over other carriers, they don't offer as many "cute" phones, they 'cripple' some User Interface functions like larger fonts: make sure you can read their submenus before buying. Some of their data services are not available while roaming.
