A Comparison of OneSimCard to Domestic US Carriers (AT&T and Verizon) for IoT SIM Card Pooled Data Connectivity


We wanted to look at our service and see how it stacks up to some of our competition – Domestic USA IoT cellular carriers AT&T and Verizon.* We chose these two networks because they have the largest footprint and overall highest ratings for their network connectivity. For the purpose of this example, we are going to assume 500 IoT SIM cards, each with a 50MB pooled/shared monthly plan.

AT&T offers a variety of SIM cards and connectivity options that range from Domestic USA to North America and International options. They also break their services down by NB-IoT/CAT M and full LTE depending on the speed you need and overall performance (e.g., battery life) you need. AT&T offers a “Steered” data SIM where they force all of the data to be transmitted over their network, so long as there is even a slight signal; they do not want to allow you to roam on another network if at all possible. They also have limitations on the amount of SIM cards that can be on an account/pool – 500. 

Verizon has a more streamlined set of plans because for their IoT SIM card plans they are only offering NB-IoT or Cat M/M-1 plans. These are also Steered plans, and there does not seem to be a limit of SIMs that you can put onto an account, but the speeds are limited to just NB-IoT and Cat M/M-1 making data heavy solutions very difficult.

Here in the USA, OneSimCard offers a single Multi-Network, Multi-IMSI IoT Sim Card which operates on AT&T, & Verizon, as well as T-Mobile. We also operate in over 160 countries and over 400 other networks around the world on that same single SIM card. We do not ever “Steer” your traffic like the domestic, “native” SIMs . So that is 3 concurrent networks on each IoT SIM card. OneSimCard IoT also operates in over 160 countries and over 400 other networks around the world. We allow your device to make the decision as to which network to attach…always allowing the best signal and offering tremendous redundancy built-in. 

Our IoT SIM card solution operates on 2G/3G/4G (Full LTE and Cat M/M-1) so if you have a solution that requires faster speeds, we can accommodate this need with the same SIM card that also operates on the slower Cat M/M-1 protocols. We also offer a flexible, fully customized offering for data plan sizes. From 0.5MB to 1000TB and beyond, we can create ANY size plan to fit your needs, instead of forcing you into a plan we dictate. 

Here is a table of these comparisons, including monthly shared data plan costs:

OneSimCard IoT Verizon ATT
No Steering SIM
Single SIM – all 3 Major USA Networks
2G/3G/4G Full LTE & Cat M/M-1 on Single SIM
Flexible/Custom Plan Sizes
Number of Included Countries 76 1 1
50MB Plan/SIM Monthly $5.50 $15.00 $12.00
Cost for 500 SIMs  Monthly $2,750.00 (no additional fees $7,500.00 (+fees) $6,000.00 (+fees)

This chart demonstrates how the OneSimCard has many features that the domestic carriers do not have and you can save over 60% while still using their networks + T-Mobile! What’s more, the cost in the chart provides access in 76 countries for our International IoT SIM Card, but the listed AT&T and Verizon’s data plans only include the USA – if you want international, you will pay even more. OneSimCard is also the best choice if you are looking for a true partner willing to be flexible with plans, and tailoring the solution based on your individual needs. We have in-depth conversations and needs-analysis meeting with all of our clients and develop each solution to each of our clients instead of trying to fit your project into rigid, “cookie-cutter” data plans.

Speaking of solutions, OneSimCard IoT works with many different IoT verticals, including:

  • Fleet Management
  • Connected Vehicle
  • Asset Tracking
  • Digital Signage
  • Wearables
  • Ag-Tech
  • Telemedicine
  • Smart Cities
  • Custom Projects

OneSimCard IoT SIM cards are managed on our proprietary OSCAR platform. Our Cloud-based Platform is available from any browser and on the Apple App Store and on Google Play. This allows you to manage your entire global deployment of SIM cards from virtually anywhere!
