Our verdict on each
MasMovil
MasMovil is a Spanish network selling its own SIM only lines with no minimum term, which suits readers who want a short commitment and a low entry price of €4.90. The trade-off is a narrow feature list: data does not roll over and calls over wifi are out.
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
MasMovil
Pros
- Entry price of €4.90 sits below the site median of €9.30, and it ranks 87 of 258 brands on that measure.
- Plan terms run 1 month, so there is nothing to serve out before you leave.
- Sim only tariffs are available, and eSIM is offered, so you can bring a light line without a handset.
Cons
- Data rollover is not available, so unused data is lost at the end of each cycle.
- Lonestar Cell MTN lists an entry price of $0.20, lower than €4.90, so the cheapest way in sits with that brand instead.
- Roaming in the EU runs on fair use terms rather than being included outright.
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
MasMovil
Who it suits
- Readers in the market listed as ES who want a single-market setup.
- People who want a SIM only line and a term of 1 month with no long commitment.
- Anyone who needs hotspot sharing and 5G on a budget line.
Who should look elsewhere
- Anyone who relies on rolling monthly billing, since yesss lists contract, rolling and prepaid options.
- Readers who call often from indoors on weak signal, since wifi calling is not supported.
- People who want unused data to move into the next cycle, since data rollover is not available.
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.
