US Mobile Review: Verizon, AT&T, & T-Mobile in One Plan?

Raise your hand if you’ve ever had to "settle" for a cell phone carrier.

You know the feeling: You move to a new apartment where Verizon is dead, so you grudgingly switch to AT&T. Or you get a job in a building where T-Mobile is a ghost, so you crawl back to Verizon.

For decades, we’ve been forced to pick a "team" and hope for the best.

That’s exactly what leads many power users to US Mobile.

US Mobile isn't just another budget carrier; it is the first carrier to effectively act as a "network broker." They don't just resell one network; they resell all three of the major US networks (Verizon, T-Mobile, and AT&T) under a single brand.

It’s the "Skeleton Key" of the mobile world.

But before you sign up, let’s unpack everything you need to know to decide if US Mobile is your next mobile home.

What is US Mobile?

At its core, US Mobile is a prepaid carrier that operates as a Super Carrier.

Unlike Mint Mobile (which is strictly T-Mobile) or Visible (which is strictly Verizon), US Mobile lets you choose which infrastructure you want to use when you sign up. They mask the names with cool sci-fi branding, but the hardware is the same:

• Warp 5G: This is the Verizon network.
• Light Speed: This is the T-Mobile network (formerly called GSM 5G).
• Dark Star: This is the newly added AT&T network.

This gives you a distinct advantage: You can buy a plan from US Mobile, pick the "Warp" network, and if you move to a new house next month where Verizon sucks, you can "Teleport" your existing number over to "Dark Star" (AT&T) in about 15 minutes.

What's So Different About US Mobile?

Here's the standout feature: The "Teleport" Tool.

Most carriers lock you into their coverage map. US Mobile lets you hop between networks.

• For the Indecisive: If you aren't sure which carrier is best at your office, you can literally test all three without canceling your plan or losing your number.
• For the Traveler: Going on a road trip to the boonies? Switch to Warp (Verizon). Staying in the city? Switch to Light Speed (T-Mobile) for faster 5G speeds.
• Mixed Family Plans: You can have your dad on Verizon (Warp) and your teenager on T-Mobile (Light Speed) all under the same billing account.

This makes US Mobile an ideal solution for anyone whose primary concern is flexibility and coverage, rather than just the absolute lowest price.

US Mobile Plans & Pricing (Nov 2025)

US Mobile offers a mix of "Unlimited" and "By the Gig" options.

Here is a look at how they typically structure their offerings:

• Unlimited Starter ($25/mo or $270/yr): This is the sweet spot for most. You get 35GB of premium data.
• Unlimited Premium ($44/mo or $390/yr): This is for power users. You get 100GB of premium data, 50GB of hotspot, and free international roaming.
• Unlimited Flex ($210/yr): This is an annual-only plan effectively costing $17.50/mo, but it has slower hotspot speeds and lower data caps.
• By the Gig: A "shared data" model (like the old Verizon plans) where you pay $10 for 2GB and can add more data as needed.

Note: Prices include taxes and fees, which is a rarity in the industry.

Key Things to Know Before Making the Switch

While US Mobile is a tech-lover's dream, it’s important to understand the technical trade-offs before you sign up.

1. The "Priority" Puzzle (QCI)

Not all data is created equal.

• Warp 5G (Verizon): If you have a 5G device, you generally get "Priority Data" (QCI 8), meaning you won't slow down in crowded stadiums.
• Dark Star (AT&T): By default, you are on QCI 9 (deprioritized). If you want "Priority" (QCI 8) on AT&T, you often have to pay an extra monthly fee (usually ~$4-$12) unless you are on the highest-tier Premium plan.
• Light Speed (T-Mobile): This is standard data priority.

2. Teleporting Isn't Always Free

Switching networks is magic, but it has limits.

If you are on the Unlimited Premium plan, you can switch networks as much as you want for free.

If you are on the Starter or Flex plans, you typically get your first two switches free, but subsequent switches cost $2 each.

3. "Dark Star" Growing Pains

The AT&T (Dark Star) integration is the newest addition. While coverage is excellent (it's AT&T, after all), some users have reported higher latency (lag) compared to the Verizon or T-Mobile sides of the house. It's great for coverage, but maybe slightly slower for gaming.

4. International Roaming varies wildly

If you travel abroad:

• Premium Plan: Includes native roaming (your phone just works).
• Starter/Flex Plans: You usually have to buy a separate "International eSIM" for data, which is a bit more technical to set up.

US Mobile Features

When it comes to features, US Mobile is arguably the most feature-rich prepaid carrier. You generally get:

• Hard Capped Data: Unlike other "unlimited" plans that slow you down to 2G, some US Mobile plans will hard stop your data if you hit the cap (though the Unlimited plans just throttle you).
• Customizable Perks: On Premium multi-line plans, they often offer statement credits for streaming services like Spotify or Netflix.
• Visual Voicemail & WiFi Calling
• eSIM Instant Activation

Who is US Mobile NOT For?

While they are the "Swiss Army Knife," they aren't for everyone:

• The "Set It and Forget It" User: If you don't know what a SIM card is and don't want to manage network settings, the options here might overwhelm you.
• The Store Person: There are no US Mobile stores. If you have a problem, you are chatting with support on their website (though their support is famously good).
• The Single Line Budgeter: If you only need one line and don't care about network switching, Mint Mobile or Visible might be slightly cheaper.

Ready to Make the Switch? Here's How

If having access to all three networks sounds like the solution to your dropped-call nightmares, here is how to switch:

1. Choose Your "Fighter": Check the coverage maps for Verizon, T-Mobile, and AT&T in your area and pick the strongest one to start with.
2. Order the Starter Kit: I recommend ordering the physical "Starter Kit" which comes with SIM cards for both Warp and Dark Star, just in case you want to switch later.
3. Port Your Number: Have your account number and PIN from your old carrier ready.
4. The "Teleport" Test: If you notice your signal is weak at work, log into the dashboard and initiate a "Teleport" to a different network to see if it improves.

My Takeaway on US Mobile

All in all, US Mobile is a specialized tool for the "optimizer."

They don't try to lock you in; they try to give you the keys to the castle. For me, the peace of mind knowing I can switch from Verizon to AT&T infrastructure with the click of a button—without changing carriers or losing my number—is worth the price of admission.

If you are tired of wondering "what if" the other carrier is better, US Mobile lets you find out for yourself.

Frequently Asked Questions (FAQ) / US Mobile

Which network is "Warp 5G"?

Warp 5G uses the Verizon network. If you have a 5G device, this generally offers the fastest speeds and priority data.

Which network is "Dark Star"?

Dark Star uses the AT&T network. This is often the best choice for rural coverage where Verizon falls short.

Which network is "Light Speed"?

Light Speed (formerly GSM 5G) uses the T-Mobile network. This is often the best choice for fast 5G speeds in major cities.

Does US Mobile have truly unlimited data?

Technically, no. Their plans are "Unlimited" but have a high-speed cap (e.g., 35GB for Starter, 100GB for Premium). After you use that amount, your speeds are throttled (slowed down) significantly, usually to 1Mbps, for the rest of the month.

What is the "Teleport" feature?

Teleport allows you to move your phone number from one network (e.g., Warp) to another (e.g., Dark Star) internally within US Mobile. It takes about 15 minutes. It is free for Premium users and costs $2 per switch for others (after the first two).

Can I bring my own phone?

Yes. Since US Mobile supports all three major networks, virtually any unlocked US smartphone will work on at least one of their networks.

Do they have a free trial?

Yes, US Mobile typically offers a 30-day free trial for new customers who port in a number, allowing you to test the service before paying.
