The Longest Free Carrier Trial You Can Get Right Now

When you are looking to switch carriers, time is your greatest asset. You need enough days to test the network at home, during your commute, and even on a weekend getaway to see if the signal actually holds up.

For a long time, T-Mobile’s "Network Pass" was the undisputed king, offering a massive 90-day trial. However, the market shifted significantly in mid-2025. Many carriers standardized their offers, making the "longest" trial a tie between several major players.

Here is the current leader for the longest free trial in December 2025.

The Leaders: 30 Days of Risk-Free Service

As of right now, 30 days is the maximum duration for a truly free, no-commitment carrier trial. Several companies currently share this top spot, though they offer very different experiences.

1. T-Mobile Trial (The Value Leader)

T-Mobile recently shortened its 90-day pass to 30 days, but it packed that month with more features than ever before. You get unlimited talk, text, and data, but you also get access to premium "Experience Beyond" perks like T-Mobile Tuesdays and 4K UHD streaming. It’s a 30-day window that lets you live like a high-tier customer before you spend a dime.

2. AT&T Wireless Free Trial (The Data Leader)

AT&T offers a solid 30-day trial delivered via eSIM. While T-Mobile focuses on perks, AT&T focuses on the raw numbers. You get 100GB of premium data and 25GB of personal hotspot data. If you are a heavy data user who wants to see if a network can handle your daily streaming and work needs, this is the trial to beat.

3. Verizon Free Trial (The Reliability Test)

Verizon rounds out the top three with its own 30-day offer. Like the others, it uses eSIM so you can keep your current number active while testing their "Ultra Wideband" 5G network. It’s the perfect amount of time to see if the "most reliable network" claims actually hold true in your specific neighborhood.

The "Hidden" Longer Options

If 30 days isn't enough, there is one technical way to get a longer test period, though it requires a bit more effort.

US Mobile (The 30-Day Port-In)

US Mobile frequently offers a 30-day free trial, but with a catch: you must transfer your existing phone number to get the deal. While it’s technically the same length as the big carriers, it feels more substantial because you are using the network as your primary service from day one.

US Cellular (The Footprint Favorite)

If you live in a region where US Cellular operates, they offer a 30-day "Try US" trial. This is specifically valuable for those in rural areas where the Big Three might have spots of weak coverage. Like the others, it requires an eSIM-compatible phone and ends automatically after the month is up.

Which One Should You Choose?

While they all offer the same amount of time, your choice should depend on what you are testing.

If you want to see if a network can handle your work-from-anywhere lifestyle, AT&T’s 100GB allowance is the winner. If you want to see if the "Un-carrier" lifestyle is worth the hype, T-Mobile’s 30-day trial with its extra perks is the way to go.

Regardless of which one you pick, 30 days gives you four full weekends and a month of commutes—more than enough time to make an informed decision.
