US Mobile (Unlimited Starter) review 2027

What problem does US Mobile solve?

Every other plan makes you answer one question before you buy: which network? US Mobile removes that decision by letting you pick Verizon, T-Mobile or AT&T and switch between them. That is the benefit the tagline states directly: pick your network and switch between them, with unlimited from $17.50 a month paid annually. The verdict calls it the plan that solves the question every other plan makes you answer first, and the test notes confirm it is the only carrier where you can move between all three networks. It also carries a free network trial and eSIM in minutes, so you can test the signal where you actually live before committing. It ranked 2 of 9 cell phone plans tested.

How did it score in each test category?

Value took 28 of 30 points. The measure was the monthly price for one line of unlimited with taxes and fees, plus the multi-line price for four. Coverage & network took 22 of 25, based on which network you get and measured signal at 12 metro and two rural test points. Data & speed took 16 of 20, measuring median download speed across 30 days, the premium-data cap, and how hard the plan is deprioritised when the tower is busy. Perks & features took 13 of 15, covering hotspot allowance, international use, streaming bundles, phone deals, Wi-Fi calling and eSIM. Service took 8 of 10, measuring minutes to reach support, app quality, and how easy it was to leave. The total is 8.7.

Where does US Mobile stand out?

Three things separate it from the field. First, network choice: it is the only carrier where you can move between all three networks. Second, speed: the measured median download was 112 Mbps. Third, price: the annual plan is the cheapest unlimited we tested, and the tagline puts annual billing at from $17.50 a month. Multi-line discounts and a free network trial round out the offer, and eSIM activation takes minutes.

What do you actually get?

The plan tested is Unlimited Starter on a prepaid / MVNO basis. One line is 25 $/mo and four lines are 100 $/mo total. Premium data is 35 GB, hotspot is 10 GB, and international is handled through add-on passes, free in 90+ countries on Premium. There is no contract. Network is your choice of Verizon, T-Mobile or AT&T.

How does it compare with the other plans we tested?

T-Mobile scored 8.8 at $50, with 50 GB premium data, 3 GB hotspot, unlimited texting and 2G data in 215+ countries, and no contract beyond device financing. It is ahead on score and premium data; US Mobile is ahead on price and on network choice, since T-Mobile locks you to its own network.

Visible scored 8.7 at $25 on Verizon, with no premium data on the base plan (deprioritised) and 50 GB on Visible+, 999 GB hotspot, Mexico and Canada on Visible+, and no contract. It matches US Mobile on price and beats it on hotspot, but it cannot switch networks.

AT&T Prepaid scored 8.5 at $25 on AT&T, with no premium data (deprioritised), 10 GB hotspot, Mexico and Canada included, and a 12-month prepay for the best rate. It matches on price and hotspot, and adds stores and phone support, but again you are tied to one network.

Where does it fall short?

Service is the weak spot, and it is where the plan lost: chat-only support, with 14 minutes to reach a person. The Starter plan is deprioritised at rush hour on Verizon. Perks such as streaming and international need the Premium plan rather than the Starter plan tested here.

Is it good value?

At $25 for one line and $100 total for four, it matches the cheapest plans here, and the annual plan is the cheapest unlimited we tested. The tagline puts annual billing at from $17.50 a month. Value scored 28 of 30, the highest-weighted criterion in the breakdown.

Who should buy it?

Anyone unsure which network works at home. The free network trial and the ability to switch between Verizon, T-Mobile and AT&T mean you are not locked into a guess. If you need streaming perks or free international on the base plan, look at the Premium tier instead.
