US Mobile plans
US Mobile plans: Flex is 10GB high-speed, Premium is unlimited high-speed. Some prices include taxes and fees.
Checked against official pages on November 4, 2026. Rules move; when this one does, it goes on the changelog.
US Mobile plans on the plans page, read 8 October 2026, are more than one data line. Unlimited Flex prints 10GB of high-speed data. Unlimited Premium prints unlimited high-speed data on the plan tiles. The page's own answer on unlimited plans says Premium is not slowed based on usage, Starter may be slower after 70GB a month on Warp and Light Speed while Dark Star on Starter is described as unlimited high-speed, and Flex may be slower after 10GB. Talk and text on those unlimited plans are printed as unlimited.
Tax is not one switch
A headline on the page says taxes and fees are included. The same page's answer about taxes and fees says some plans include them and some show separate charges, including a carrier service fee and a recovery fee that the answer describes as typically ranging from $1 to $5 per line. A Massachusetts tax rate belongs on a price when that plan leaves taxes out of the advertised figure. The state table keeps both statements, on US phone plans in Massachusetts.
International minutes
The plans page says international calling to 180+ destinations is included on all annual plans, on By the Gig shareable plans, and on the monthly Premium plan, and that it can be purchased as an add-on on Light and Monthly Starter. It also says that calling works on domestic US SIMs and not on an international data eSIM. India is not named in that answer. A country-by-country list was not part of this read.
Prepaid versus a credit check is on getting a US phone plan without an SSN. Annual prices printed on the same page, including a first-year Premium figure, are left on the carrier page rather than copied here, because the monthly tile and the annual renewal are different cells.
Activation geography
US Mobile's public help splits "how activation works" from "what roaming needs." The activating or transferring guide, read 4 November 2026, walks through network choice, eSIM or physical SIM, new number or port-in, and install. In the text we read, that guide does not state that you must be physically inside the United States to press activate.
| Step | What the pages we read say |
|---|---|
| Purchase while abroad | unverified on a dedicated purchase-geography article in this read |
| First activation, new number | Steps are on the activation guide; a U.S.-presence requirement is unverified on that guide |
| Port-in | Supported on the same guide (account number and transfer PIN); a U.S.-presence requirement for port-in is unverified there |
| eSIM download or install | Install link, QR, or manual entry on the line page / email, per the same guide |
| First domestic use | Required before international roaming will work (next section) |
| Country exceptions for activation | unverified |
Do not read the roaming sentences below as a copy of Tello's "you must be in the U.S. to activate" rule. They constrain roaming after how the line was brought up.
Roaming and Wi-Fi Calling after activation
According to US Mobile's international coverage options page, read 4 November 2026: "Your line must have domestic usage (inside the United States) first to be able to use international roaming. Roaming won't work if you activate the line outside the US."
| After activation | What the pages we read say |
|---|---|
| Native international roaming | Needs prior domestic usage; the native roaming article repeats that a line never used domestically will not roam |
| Turning roaming on for a trip | The roaming checklist says the listed prep steps must be done on a domestic U.S. connection |
| Turning Wi-Fi Calling on | The Wi-Fi calling help page says you need to be within the U.S. in a coverage area to turn it on (Warp and Dark Star note; Light Speed uses the dashboard path on the same page) |
| Using Wi-Fi Calling once abroad | The native roaming article has a Wi-Fi Calling abroad section. Calls back to US numbers are generally included. Calls to local foreign numbers while abroad may incur additional charges, and that section points to the plan's Wi-Fi Calling terms. Device and connection limits beyond that sentence stay on the plan page |
| Bank or OTP SMS | Not promised on these help pages; start at why OTP SMS fails abroad |
Coverage while roaming also differs by network (Light Speed, Warp, Dark Star) on the coverage-options page. That is a destination list, not an activation-geography rule.
Questions
Is Flex unlimited data?
Flex prints 10GB of high-speed data, and the page says speeds may be slower after that 10GB. Premium is the tile that prints unlimited high-speed data.
Do all US Mobile plans include taxes?
The page says some plans include taxes and fees and some do not. Read the plan you would buy. The included label on one tile does not cover the plans the tax answer sets aside.
Does US Mobile say I must stand in the U.S. to activate?
The activation guide we read does not print that sentence. The coverage-options page does say roaming will not work if you activate the line outside the U.S., and that domestic usage comes first.
