Choosing an unlimited Internet plan for your cell phone isn’t always straightforward. Unlike home Internet, which usually comes with a few clear options, most Americans have to compare multiple wireless plans, each with different pricing, data limits, and coverage claims.
Many of these plans advertise “unlimited” data but come with conditions that affect real performance, like throttling after certain usage thresholds or extra fees for mobile hotspot use.
In this article, we break down what "unlimited" really means, what to watch out for in the fine print, and how to evaluate your options based on your actual data usage.
Most unlimited data packages include unlimited minutes, unlimited messages, and unlimited high-speed data (up to a specified data ceiling). This high-speed data allowance is usually 22–23 gigabytes (GB). Some major carriers charge more for unlimited plans with more extensive data caps, sometimes surpassing 50 GB per month or even 100GB before throttling.
Most carrier plans have quotas on data consumption, speeds, or other restrictions in the fine print that you should be aware of. Despite their name, unlimited data plans are no exception.
These thresholds are known as data deprioritization limits. Once you pass them, your speed may slow during periods of network congestion, not always, but often when you're in busy areas or using data at peak times.
Hotspot data is another area with restrictions. Even on unlimited plans, personal hotspot use is usually capped separately, often around 5–15 GB, after which speeds may drop to 600 Kbps or lower.
Streaming an hour of HD video can use around 3 GB. So if you regularly stream content, tether a laptop, or game on your phone, those caps can be reached quickly.
Not all unlimited plans are the same. We've compiled a list of criteria that every consumer should examine before signing up for an unlimited data plan. Here's what you should be on the lookout for:
Determine how much data you'll require each month. This will reveal a lot about whether or not an unlimited plan is right for you.
If you mostly browse the web, use messaging apps, and stream occasionally, you may not need the highest-tier unlimited plan. On the other hand, if you regularly stream HD video, tether devices, or work remotely, you’ll need a plan with a higher deprioritization threshold and hotspot features.
Always check what the provider means by "unlimited". Most plans slow your data after a certain point or restrict hotspot usage even if the base data is unlimited.
Most networks will provide excellent coverage if you live in a big city. However, one network may provide superior service outside of cities compared to others. A coverage map might help you determine which networks are best for your area; Optimum's coverage map can be found here.
Will you set up a mobile hotspot on your phone? Do you desire free streaming service subscriptions? Are you planning to travel internationally for business? Different unlimited plans may include bonus features to complement your usage needs. Make sure to consider these benefits when making your final decision.
If you travel, stream a lot, or want to share your plan with family, these extras can make a big difference.
