Mobile phone users and Carriers in the United States.
Approximately 310,888,450 people in the US own a mobile device. Of these users, approximately 251,983,270 own a smartphone. The top five smartphone manufacturers by market share are Apple, Samsung, LG, ZTE, and Motorola. Lastly. The top five carriers by market share are Verizon Wireless, AT&T, T-Mobile, Sprint, and US Cellular. I've included a sixth carrier, America Movil, because it has a higher market share than US Cellular, but it is an MVNO (mobile virtual network operator) and thus does not have its own network. I've compiled the figures for the top five manufacturers and carriers into the attached spreadsheet.
Number of mobile device and smartphone USERS
To determine the number of mobile device and smartphone users, we'll use the current estimate of the population using the US census bureau as well as some statistics regarding mobile device usage. The current population of the US is 327,251,000 (and rising). We'll use this figure for our estimates. According to Pew Research, 95% of Americans own a cell phone and 77% own a smartphone. These figures are from 1/10/2018.

Market share: smartphone manufacturers
The market share for smartphone manufacturers has been determined by the number US vendor shipments in Q3 2017. During this period, 39,500,000 units (smartphones) were shipped in the US. The market share breakdown is as follows:
1. Apple — 30.4% or 12,000,000 units
2. Samsung — 25.1% or 9,900,000 units
3. LG — 17.2% or 6,800,000 units
4. ZTE — 11.6% or 4,600,000 units
5. Motorola — 5.2% or 2,100,000 units
Market share: carriers
The market share for carriers has been determined by the subscriber count. These figures are from Q3 2017. The market share breakdown is as follows:
1. Verizon Wireless — 148,874,000 subscribers
2. AT&T — 138,826,000 subscribers
3. T-Mobile — 70,731,000 subscribers
4. Sprint — 53,074,000 subscribers
5. US Cellular — 5,089,000 subscribers
*America Movil — 23,100,000 subscribers
As you may have noticed, the subscriber count adds up to be more than the 251,983,270 figure we calculated above. This is likely due to some users having multiple devices, and thus, multiple subscriptions. For example, someone may have one device for personal use and another for business use.
*America Movil is a mobile virtual network operator (MVNO). MVNOs do not have their own network, and thus operate on the networks of other carriers. They generally use the networks of the top four in the list above. Despite this, America Movil has more US subscribers than US Cellular, so I've decided to include it here. The data for their subscriber count is from Q4 2017.
