Our verdict on each
MobileX
MobileX suits US readers who want a prepaid plan with a low entry price and no contract attached, scoring 9.4 overall. Build Your Own starts at $3.88 on 1 month, and that same monthly rate carries into every later period, so nothing has to be unwound at renewal.
US Mobile
US Mobile suits US households that want a prepaid shared data plan or an annual unlimited tier, and it scores 9.1 overall for price and offer. The trade-off is the annual term behind the cheapest unlimited rate and a missing multi line discount for families buying more than one line.

Pros and cons
MobileX
Pros
- Build Your Own starts at $3.88 on a plan where the data allowance is set by the customer
- Plans run 1 month, so there is no long term to serve
- Unlimited talk and text plans start at $14.88
Cons
- European roaming is paid, so travel adds cost rather than arriving with the plan
- The seller type is mvno, so service runs over a host network and local coverage needs checking
- Coverage is listed for US, so anyone who needs service across several countries should look wider
US Mobile
Pros
- Shared data starts at $10 a month on the By the Gig plan, one of the lower entry figures in the listings.
- Unlimited Starter annual comes in at $16.58 a month, below the monthly Unlimited Flex tier for anyone willing to hold a yearly term.
- EU roaming is included across 180 countries, a package only 36.1% of the site listings include.
Cons
- Multi line discount is not offered, although 97.5% of prepaid listings include one, so a family pays full price on every line.
- US Mobile sells as mvno, while Lonestar Cell MTN is network, so readers who prefer to buy from a network operator have fewer like for like sellers to weigh.
- The lowest unlimited rate of $16.58 is tied to the annual term, and contract lengths run 1 and 12 months, so month to month flexibility costs more per month.
Who each suits
MobileX
Who it suits
- Residents of US who want a prepaid plan with no long contract
- People who want unlimited talk and text from $14.88
- Readers who want an eSIM, rollover data and hotspot sharing on a flexible plan
Who should look elsewhere
- GETESA readers who would rather buy from a network than a mvno
- Lonestar Cell MTN readers who want the network itself rather than a virtual brand
- Travellers who need roaming inside the monthly plan, since European roaming is paid
US Mobile
Who it suits
- Households in the US that want a prepaid line with rollover, so unused data carries over rather than disappearing.
- Travellers from a US base who want roaming included across 180 countries without a separate roaming plan.
- People comfortable running on a host network and managing their own plan, since the seller type is mvno.
Who should look elsewhere
- Readers who want to buy from a network operator rather than a host network, since GETESA at network, Lonestar Cell MTN at network and yesss! at network all sit on the network side.
- Shoppers buying several lines and expecting a multi line discount, because none is offered here.
- Anyone living outside the US, since the plan market is US.

Questions about each
MobileX
What is the cheapest MobileX plan?+
Build Your Own starts at $3.88 and you set the data allowance on it yourself. The published reference prices for the plans are monthly and month to month, so that entry figure is the ongoing figure rather than a promotional rate that changes later. A reader comparing a low headline price with a long contract deal is comparing two different structures here, not two stages of one sale.
Does MobileX use contracts or lock-ins?+
No long term is attached. Billing is prepaid and rolling and plans sit at 1 month, the short contract length that flexible mobile deals tend to use. Nothing ties you in for a year, so a reader who wants to change plan or walk away can do so without serving out a term first.
US Mobile
What does the cheapest plan cost?+
The By the Gig plan is the entry plan at $10 a month, with a shared data pool across the lines on the account. Unlimited Starter, the annual tier, is the unlimited option at $16.58 a month, and Unlimited Flex adds a high-speed allowance to the unlimited range on a monthly basis.
What happens to the price after the first year on the unlimited plan?+
The plan contract options run 1 and 12 months, so the annual unlimited tier sits alongside a shorter monthly term. Unlimited Starter is listed at $16.58 a month on the annual term, and the monthly unlimited alternative, Unlimited Flex, is priced higher per month.
