Our verdict on each
PremiumSIM
PremiumSIM suits people in Germany who want a low entry price on a sim only plan, a wide support choice and a fibre option from the same seller. Sim only tariffs start at €6.99, and the fixed line runs on fttc and fttp.
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
PremiumSIM
Pros
- Sim only plans start at €6.99, below the €9.30 median across listed brands
- Terms run 1 and 24, so a rolling option sits next to a longer commitment
- 5G, eSIM and wifi calling are all available, which is what most listed mobile plans carry
Cons
- The fibre line carries a setup fee of €49.99 and post contract pricing of €44.99
- As an mvno, the provider sets its own tariffs on another carrier's network and stays inside DE
- Uploads of 5.8 to 40 Mbps sit below downloads of 1,000 Mbps, which matters for sending large files
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
PremiumSIM
Who it suits
- People in Germany who want a sim only plan on 1 and 24 terms
- Households that want mobile and a fibre line from one seller, with €49.99 to budget for at the start
- Travellers who need EU roaming included in 33 countries
Who should look elsewhere
- Anyone after unlimited data, since no unlimited plan appears among the reference plan prices
- Buyers who want the host network itself, where yesss! sells as a network
- People who need service beyond DE, with Lonestar Cell MTN listed as a network
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
PremiumSIM
What does the cheapest PremiumSIM mobile plan cost?+
The starting price across the range is €6.99, set on a small allnet plan. A second reference plan adds a much larger data allowance at a higher monthly cost, and no unlimited plan appears among the reference plan prices. Heavy data users would pay for the larger tier from the first bill.
How long is the contract?+
Plan contract months run 1 and 24, so a short rolling arrangement sits alongside a longer commitment. Billing is offered as contract or rolling, which lets you match the term to how long you expect to keep the line. Households that expect to move soon should read the longer term carefully.
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.
