Our verdict on each
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.
yallo
yallo suits Swiss readers who want a line costing nothing until they use it, on a rolling monthly setup over Sunrise's network with Europe roaming already covered. Entry is CHF 0 a month and the unlimited tier starts at CHF 21.90, and the free plan is the reason to look here first.

Pros and cons
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.
yallo
Pros
- yallo starts at CHF 0 a month on a pay-as-you-go basis, so a second line costs nothing until it is used.
- Billing is rolling and prepaid and the plan contract length is 1 month, so a reader can leave without a long notice period.
- Europe roaming is included and the host network is Sunrise, so travel abroad does not require a second provider.
Cons
- On unlimited data yallo ranks 87 of 173, far behind its 1 of 258 showing on entry price.
- yallo is an mvno on the Sunrise network, while getesa and yesss! are listed as a network in their own right.
- Service runs in CH only, so readers based anywhere else need a different brand.
Who each suits
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.
yallo
Who it suits
- People in Switzerland who want a spare or second line without a contract, starting at CHF 0 a month.
- Travellers from Switzerland who need Europe roaming already included rather than a separate roaming add-on.
- Readers who are happy with pay-as-you-go data but still want eSIM, 5G and WiFi calling on one prepaid plan.
Who should look elsewhere
- People who would rather buy from the carrier itself, since getesa and yesss! are both listed as a network while yallo is an mvno.
- Readers outside CH, where yallo does not run at all, should look at a brand built for their market, such as lonestar-cell-mtn.
- Anyone whose main goal is the lowest unlimited rate, since yallo sits at 87 of 173 on that measure.

Questions about each
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.
yallo
What does yallo cost at the start?+
The Prepaid plan starts at CHF 0 a month, so opening a Swiss number costs nothing on its own. Data on that plan is pay-as-you-go, meaning you pay for what you use. There is no minimum contract on the prepaid tier, so a line can be opened, used lightly and closed again without a long commitment.
How much is unlimited data on yallo?+
The Swiss Max plan, which carries unlimited data, costs CHF 21.90 a month with no minimum contract. A further unlimited tier costs more than Swiss Max and also comes without a minimum contract, so the rate you renew at is the rate you start at rather than a promotional step up later.
