Scrutinize Coverage and Roaming

Signing contracts might be your only option, so make sure the carrier’s coverage is adequate. Discuss with employees which carrier seems to work the best at your business locations, in the region, and from their home offices. You can also try a crowdsourced map such as Open Signal Maps or RootMetrics, where users report and track the strength of their signals. If you don’t receive good cell coverage inside your workplace buildings, determine whether the carrier you’re interested in offers coverage extenders. displays wireless coverage heat maps based on reports from Android users.
Don’t forget to check the coverage maps for locations where employees might travel. No carrier provides 100 percent coverage everywhere, and in some places you might get coverage only by using another carrier’s network. That arrangement is fine on occasion, since most carriers provide free roaming. Keep in mind, though, that most limit your roaming usage, so you need to be careful if you think an employee might be in roaming locations a significant amount of time.

For details about each major provider, see the AT&T, Sprint, T-Mobile, and Verizon coverage maps on the carriers' respective websites. Be sure to look at the separate voice and data coverage. And if you’re expecting to use the data plan often, check for 4G coverage for higher speeds.

If your employees travel outside the United States, check international coverage and roaming charges for calls, messaging, and data, from AT&T, Sprint, T-Mobile, and Verizon. Most of the major providers support international use, but smaller or regional carriers usually don’t. If someone on your staff plans on using their mobile device internationally, consider adding an international package to that person's account only for the time they’re gone, averting per-use charges.

Select a Phone

Most carriers support all the major phones and mobile OSs, including iOS for the iPhone, as well as RIM BlackBerry, Android, and Windows Phone 7 models. One major exception is that T-Mobile doesn’t officially carry iPhones; only unlocked iOS devices will work on its network.

Most mobile carriers offer free handsets, but typically require two-year contracts along with them. If employees really need only basic voice service, stick with basic or classic phones. You can get older smartphones for free (mostly Android-based devices and some BlackBerry ones), but usually only by purchasing a data plan of $30 or more a month per line. iPhones are not deeply discounted, as they run from $100 to $400, but refurbished ones cost less.

Compare Voice Plans

You’ll find that most carriers offer separate individual and group plans for consumers and businesses. With a group plan, multiple lines share a pool of minutes; typically this arrangement costs less than buying individual plans. The prices and features for consumer and business-group plans are generally the same. Consumer plans, however, typically limit you to adding up to five lines, and some providers don’t offer unlimited usage for business lines.

Prepare to spend hours crunching the numbers to determine whether a carrier's unique features will save you money.
Mobile plans, pricing, and features change too often for me to list details, but you should look for special savings in the fine print when comparing carriers. Here are several examples.

  • For select plans, AT&T offers the free Rollover Minutes feature, which saves unused minutes at the end of each month for use in future months if you exceed your anytime minutes.
  • Sprint’s Any Mobile, Anytime free feature on select plans lets you call any mobile phone within the United States at no charge.
  • AT&T’s A-List and Verizon’s Friends and Family free features on select plans allow you to specify, for each line, up to ten numbers that a user can call at no charge.
  • T-Mobile offers Wi-Fi Calling for Business, which can help reduce the amount of minutes you need and dramatically lower international roaming for users connected to a local Wi-Fi hotspot or network.

When comparing voice plans, keep your eye out for additional phone services, such as call transferring, line hunt, conferencing, group voicemail, and toll-free number support. If you think push-to-talk will be useful, make sure the carrier supports it.

Review Email and Collaboration Services

Most phones include a free email client that you can set up for basic access to email. Even classic "dumb" phones typically include this feature; however, they often require a data plan (or per-usage charges) or an email service add-on to your voice plan.

Smartphones also provide calendar and contact syncing support for consumer and corporate email users. If your organization doesn’t have an email server, such as BlackBerry Enterprise Server or Microsoft Exchange, some carriers provide BlackBerry Internet Service accounts for BlackBerry devices, or Microsoft Direct Push for Windows mobile devices.

Look at Extra Devices and Services

In addition to classic phones and smartphones, consider wireless Internet connectivity for your laptops, netbooks, tablets, and other Internet devices. You'll find many methods to get these devices connected as well.

How to Choose a Mobile Carrier for Your Small Business
If you have a data plan on your phone, you could tether its access to a computer via USB cable or any other device via Wi-Fi. Note, however, that most carriers charge a monthly tethering fee on top of the data-plan fee, unless you have an unlocked or rooted device (which likely makes the tethering against the carrier's policies).

Some newer laptops and netbooks now have 3G or 4G connectivity already integrated, just as devices have included Wi-Fi support for many years. For those computers without built-in connectivity, carriers offer PC Cards for laptops and USB adapters for netbooks and desktops.

If multiple employees tend to travel together, consider mobile Wi-Fi hotspots, which most carriers offer. Such devices basically act as a miniature Wi-Fi router that picks up the Internet from the 3G or 4G signal. Most carriers supply devices that can provide Wi-Fi connectivity for up to five Wi-Fi computers or devices at a time.
