Our verdict on each
1pMobile
1pMobile suits adults in the UK who want a cheap Sim only line, an eSIM, no credit check and a rolling monthly option they can leave quickly. It scores 9 overall, with plans starting at £5 a month, and the unlimited tier landing mid table on our price comparison.
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
1pMobile
Pros
- Plans start at £5 a month, and billing runs rolling and prepaid with terms of 1 and 12 months, so a reader can start small.
- No credit check is required and an eSIM is available, which means a new number can be live without a handset.
- 5G, WiFi calling and hotspot sharing are all included, and a multi line discount applies to households.
Cons
- EU roaming is fair use rather than included, and roaming overall reaches 46 countries.
- Terms run 1 and 12 months, so the rolling option is the pick for anyone who might move, and the annual plan only makes sense for readers already settled.
- 1pMobile is an mvno, while GETESA, Lonestar Cell MTN and yesss! all sell as network providers, so a reader who wants the operator itself is looking at a different kind of seller.
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
1pMobile
Who it suits
- Adults in the UK who want a Sim only line at the cheap end of the price range and can set up an eSIM themselves.
- Households adding a second line, where a multi line discount applies.
- Readers who want a rolling monthly line they can end quickly, with no credit check at signup.
Who should look elsewhere
- Anyone who wants to buy from the network operator rather than an mvno: GETESA and yesss! sell as network and network providers.
- Heavy data users on a tight budget, since the unlimited plan costs £25 a month, with the network sellers GETESA, yesss! and Lonestar Cell MTN the ones to price against.
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
1pMobile
What does 1pMobile cost to join?+
Plans start at £5 a month, and that figure belongs to the smallest data allowance in the range. A heavy user should budget on the unlimited plan rather than the entry number. The entry figure is a month to month spend, not an introductory deal that resets later.
How much is the unlimited data plan?+
The Unlimited plan is listed at £25 a month. It is the price to hold in mind for anyone who regularly uses more data than a capped allowance allows, and it is the figure that pushes 1pMobile further back in our price comparison than its entry plan does. Readers who stay well inside a small allowance pay far less.
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.
