Optimum Mobile is an MVNO (Mobile Virtual Network Operator) that offers discount cell phone plans to Optimum Internet customers. Switching can save you up to $600 annually on your wireless service.

Optimum Mobile operates on T-Mobile's network, which means you get cost-effective plans without sacrificing 4G LTE and 5G coverage or quality.

I'll share my extensive industry knowledge and expertise in this guide to show you this carrier's benefits, drawbacks, and more. That way, you can make an informed decision about whether Optimum Mobile (formerly Altice Mobile) is right for you.

1. Is Optimum Mobile good?

After personally comparing different carriers, I've found that the Optimum Mobile plans stand out with advantages like reliable network coverage and competitive pricing. Of course, there are both pros and cons to this low-cost carrier:

Optimum Mobile advantages:

  • Unlimited talk and text included in all plans
  • Dedicated mobile hotspot data with unlimited plans
  • International roaming available
  • 24/7 customer support

Optimum Mobile disadvantages:

  • Lower prices only for Optimum Internet customers
  • Autopay required

2. Optimum Mobile cell phone plans

Carrier Network Data Price

Optimum Mobile 3GB plan T-Mobile 5G/4G Coverage 3GB $25/mo
Optimum Mobile unlimited data plan T-Mobile 5G/4G Coverage Unltd $45/mo

Optimum Mobile has a surprisingly diverse set of cell phone plans. Whether you're a light data user or must have an unlimited data plan for video streaming or gaming, they've got you covered. In fact, there are two different Optimum Mobile unlimited plans to choose from.

All plans include unlimited talk and text. Plus, this MVNO edges out the competition with a specific Travel Pass feature, which makes communicating abroad more convenient if you're a frequent traveler.


3. Optimum Mobile 5G & 4G LTE coverage

Optimum Mobile coverage map

The FCC collects coverage data, which only offers an approximate indication and doesn't account for indoor coverage. The actual speed and performance can vary depending on your location and device. The reception you experience is influenced by local conditions and elements like natural and artificial physical features in your area.

MVNOs don't own their own networks. Instead, this low-cost carrier leverages the power of the 4G LTE and 5G wireless coverage from the T-Mobile network. This means you get the same coverage and data speeds as T-Mobile customers at more affordable prices.

Every wireless network has its flaws. However, according to a recent Opensignal report, statistical analysis demonstrates T-Mobile's download speeds to be more than double those of its competitors.

On the flip side, keep in mind that it's common for MVNOs to experience slowed data speeds during times of network congestion.

New to the network? See our Optimum Mobile coverage map to verify coverage in your area.


4. Optimum Mobile unlimited data

Optimum Mobile offers two unlimited data plans with high-speed data caps weighing in at 20 GB and a robust 50 GB.

Once you hit your monthly data cap, you'll be slowed to 3G data speeds. To reduce data consumption, you can connect to one of Optimum Mobile's free Wi-Fi hotspots wherever available.
