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.
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
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
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
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
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
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.
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.
