When I started writing forZDNet15 years ago, mobile phones were being used by 74% of the US population, but only 14% of those people were using these basic phones to access the internet. Thelatest data shows that 97% of Americans own a mobile phone, with 85% of those being smartphones that access the internet multiple times a day.

Smartphones and wireless cellular services are now essential for businesses to compete in today's market and broad coverage is an expectation. After T-Mobile's recent acquisition of Sprint, the US market is dominated by Verizon, T-Mobile, and AT&T. Each of these carriers offers various plan options for businesses of all sizes.

5G continues to roll out across the US, but reliable LTE service is still essential to getting work done. The pricing for business service is competitive, and as someone who has been in the industry for decades, it is amazing to see the reasonable pricing for such fast service that reaches across the nation.

MVNO options for businesses

While the three major carriers offer focused business plans, there are also a few MVNOs that offer attractive per line plans that may work well for small businesses. MVNOs (mobile virtual network operators) are companies that use establish wireless carrier infrastructure to provide no or minimal contract options for customers. The MVNOs do not openly advertise which wireless carrier infrastructure they are using, but as soon as you insert a SIM into your phone, you can see which carrier is connected to which MVNO. MVNOs are optimized for consumers looking for phone service with no contracts and prepaid options, but these same elements may help small businesses control costs and adjust to market demands.

What steps should a new business take to establish wireless service?

While this buying guide provides current pricing and service options from the three primary US wireless carriers and MVNOs, specific pricing for your business requires a conversation with the carrier to fully define your company needs, available service discounts, and contract lengths.

One of the first things to figure out is where you will need service geographically in the US as all three carriers have slightly different coverage maps. Your geographic operating area may remove one, or more, carriers from your viable candidate list. 

The next step is to determine how many lines of service you will need and then the data needs of those lines. Calling and text messages are unlimited in all cases, but data speed and amount of data will drive your costs.

Most carriers also offer additional incentives and services, such as hotspot, in-flight coverage, Microsoft 365, and more. Make sure to account for the value of these incentives in your decision-making process.

What are the disadvantages of a MVNO?

Most MVNOs are focused on the consumer market so business plan offerings for more than six lines of service are rare. Pricing can be very competitive and with no contracts these MVNOs may be attractive to businesses just getting started that do not want to lock in long-term contracts.

Account management may require more time from businesses given the consumer focus of MVNOs. MVNOs are also subject to the infrastructure provided by the big three US carriers, but there are several established MVNOs with solid reputation and a record of high-quality service and support.

What is the best business phone plan?

We analyzed reliability, coverage, and price to compile a list of the best phone plans for your business which includes: Verizon, AT&T, and T-Mobile.

Does the choice of my smartphone model limit wireless service?

In the past, the US wireless market was split into GSM and CDMA service technologies with two carriers supporting each of these technologies. Modern smartphones support LTE and 5G service without CDMA technology your choice of smartphone is not as limited.

The most popular smartphones in the US, Apple iPhones and Samsung Galaxy phones, support all wireless technologies in the US wireless market so there are no limits on using these phones with any US carrier. If you purchase these phones directly from Samsung and Apple, then you can choose to purchase unlocked models.

Some phones are sold in a locked state so they can only be used on one specific carrier. This may be changing soon and there are processes to unlock your phone from your carrier if you decide to switch carriers. There used to be incentives for purchasing locked phones, but in today's world purchasing unlocked phones gives you the most flexibility for choosing your service provider.
