1pMobile

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
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.
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
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.
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
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.
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.
