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
Astound
Pros
- Download of 5,000 Mbps matches upload of 5,000 Mbps, so sending a large file is as quick as downloading one.
- The setup fee is $0, and it ranks 1 of 86 on that measure, ahead of every other brand compared.
- Service runs on cable and fttp, so one provider can cover a cable street or a fibre to the home street.
Cons
- EU roaming is paid, so European travel is billed separately.
- Data rollover is no, so unused mobile allowance does not carry into the next cycle.
- A credit check is required on the mobile side, which adds a step before a line is active.
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
Astound
Who it suits
- Households in US whose street already has cable or fibre to the home and who want equal download and upload speeds.
- Families adding mobile lines to the same account, where a multi line discount and rolling billing apply.
- Renters and short-stay households, since No cancellation penalty; change or cancel anytime.
Who should look elsewhere
- Buyers who want a fibre to the home provider and nothing else, because cable and fttp includes cable while Abissnet and Kinetic list fibre to the home alone.
- Homes a wired network does not reach, where EarthLink adds fttp, 5G and satellite options.
- Travellers who expect European roaming to come included, since EU roaming is paid.
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
Astound
How much does Astound broadband cost a month?+
Plans start at $19.95 a month on the entry tier. The listed lineup then steps up through Gig and multi-Gig WiFi plans, and every plan shown is on no-contract terms, so the monthly figure is the whole commitment. Whole Home WiFi is included with Gig plans rather than sold as an extra.
Is there a setup or installation fee with Astound broadband?+
Setup costs $0 to add, and in this comparison the brand ranks 1 of 86 for setup fee, ahead of every other brand measured on that point. Equipment also counts: Whole Home WiFi is supplied with Gig plans, with the top tier hardware paired to the quickest speeds.
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.
