Our verdict on each
sim.de
sim.de suits people in Germany who want a cheap sim only line with a monthly option and a fixed contract choice on the same tariff sheet. It runs on the 1&1 network, and its entry price of €6.99 sits well under the market median for entry pricing.
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
sim.de
Pros
- Entry pricing of €6.99 is below the site median of €9.30
- The Unlimited on demand plan costs €19.99, under the site median unlimited price of €23.19
- Contract terms run 1 and 24, so a plan can sit on a monthly term or a longer one
Cons
- The Unlimited on demand plan is tied to the longer of 1 and 24, so unlimited data is not offered on a monthly term
- Service runs in DE only, so the tariffs are not offered outside that market
- As an mvno, sim.de sells on the 1&1 network rather than owning it, unlike the network operators getesa, yesss! and Lonestar Cell MTN
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
sim.de
Who it suits
- People in DE who want a data heavy sim only line without paying for a handset
- Travellers from DE who want roaming included and reach across 33 countries
- Households that want one provider offering both a short monthly term and a longer fixed contract
Who should look elsewhere
- Buyers outside DE, since the service is a single market
- People who want a handset bundled with the tariff, as the plans are sim only
- Buyers who want unlimited data on a rolling monthly basis, since the Unlimited on demand plan sits on the longer of 1 and 24
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
sim.de
How much does a sim.de sim only plan cost to start with?+
The cheapest way in is the entry data plan at €6.99 per month, and it can run on a monthly term rather than a long contract. The larger data plan and the Unlimited on demand plan sit on the longer of 1 and 24 instead.
How much is unlimited data on sim.de?+
The Unlimited on demand plan costs €19.99 per month, and it is tied to the longer of the contract options, 1 and 24. That price sits under the site median unlimited price of €23.19, but the commitment is the part to weigh.
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.
