iPhone on US Mobile

Which iPhones work on US Mobile

The compatibility rule is simple: any unlocked iPhone from the iPhone 6 onward works. Carrier-locked phones need to be unlocked first through your previous carrier before they'll activate.

eSIM support extends the list further. iPhone XS and XR (2018) and every model after them support eSIM. iPhone 14 and later US models are eSIM-only — no physical SIM slot — but US Mobile supports eSIM across all three of its networks, so those models work fine.

If you're shopping for a phone to pair with US Mobile, see our guide to refurbished iPhones — older unlocked models are often the best-value option.

US Mobile plan pricing

US Mobile offers two plan structures. By the Gig charges only for data you actually use, which suits light users. Unlimited plans make sense once you're consistently hitting 10 GB or more per month. Annual billing cuts the monthly cost on unlimited plans.

All plans include unlimited talk and text. Prices shown are single-line with autopay. Check US Mobile directly for multi-line discounts and current promotions.

Which plan to choose

If you use under 5 GB a month — calls, messaging, occasional browsing, maps — By the Gig is almost certainly cheaper than any flat-rate unlimited plan. A typical light user spends $15–$20/mo. Heavy streamers or hotspot users will hit the point where Unlimited Starter pays off faster.

The smartest combination for most people: a refurbished iPhone on the By the Gig plan, on whichever of Verizon, AT&T, or T-Mobile gives the best signal where you spend most of your time. Total monthly cost often lands under $20.

US Mobile's three networks explained

US Mobile calls its Verizon network Warp, its AT&T network Dark Star, and its T-Mobile network Light Speed. You choose one at signup, but you're not locked in. The Teleport feature lets you switch networks without changing your number or plan — useful if you move, travel frequently, or realize coverage at home is weak on your current network.

No single network is best everywhere. Verizon tends to lead in rural and suburban coverage. T-Mobile has stronger 5G depth in cities. AT&T fills in a different mix of gaps. If you're unsure which to start with, check a coverage map for your ZIP code before signing up.

Compared to single-network MVNOs like Mint Mobile (T-Mobile only) or Visible (Verizon only), US Mobile's multi-network flexibility is its main differentiator. If you know which network is best in your area and want the absolute lowest price, a single-network MVNO may be cheaper. If you're unsure, or if you split time between areas with different coverage, US Mobile is worth the slight premium.

How to set up an iPhone on US Mobile

1. 1
   Check compatibility and unlock status. Your iPhone must be unlocked. If you bought it outright from Apple, it's already unlocked. If you financed it through a carrier, contact that carrier to confirm it's eligible for unlocking and request the unlock before switching.
2. 2
   Choose your network. Check Verizon, AT&T, and T-Mobile coverage maps for your home address and any other places you spend significant time. Pick the network with the strongest rating across those locations — you can always switch later via Teleport.
3. 3
   Pick a plan and sign up. Select By the Gig for light usage or Unlimited Starter if you're unsure. Annual billing saves money if you commit. Enter your information at US Mobile's site to create the account.
4. 4
   Activate eSIM and port your number. For iPhone XS or newer, activate via the US Mobile app or dashboard — scan the QR code or enter the activation details and the eSIM installs in minutes. Porting your existing number usually completes within a few hours. Older models use a physical SIM card mailed by US Mobile.

When US Mobile beats a single-network carrier

US Mobile's multi-network setup adds the most value in two situations. First, if you move around — between cities, or between urban and rural areas — no single network is reliably best everywhere, and the ability to switch without switching carriers saves real hassle. Second, if the network that covers your home area is not the obvious default (T-Mobile is cheapest through many MVNOs, but if T-Mobile coverage at your apartment is poor, you'll be unhappy with a T-Mobile-only MVNO).

For someone who stays in one metro area and already knows which network is strong there, a specialist MVNO like Mint Mobile may undercut US Mobile on price. But if you're not sure which network to pick, US Mobile lets you try and switch without re-signing for a new carrier.
