Pros and cons
T-Mobile Polska
Pros
- Two billing styles in one place: contract and prepaid covers both a prepaid card and a contract SIM, so a short month and a longer plan come from the same seller type of network.
- Unlimited data is priced at PLN 75 on the Abonament komorkowy plan, which also ranks 59 of 173 brands on that measure.
- Sim only is available, so you can bring your own handset and pay only for the network side.
Cons
- The contract plan runs 24 months, so the unlimited price is tied to a long commitment rather than a rolling monthly deal.
- EU roaming is on fair use terms, which is weaker than plans that include roaming in the monthly price.
- The range runs in Poland, so the plan, support and the prepaid card are aimed at Poland only.
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
T-Mobile Polska
Who it suits
- People living in Poland who want a plan sold by the network itself rather than a reseller, given network and PL.
- Shoppers who want both a prepaid card and a contract option on the same account, since contract and prepaid lists both.
- Households wanting a multi line discount, or travellers who want eSIM and Wi-Fi calling included.
Who should look elsewhere
- Anyone outside PL, where the prepaid card and contract plans do not reach.
- People who want EU roaming included in the monthly price, since fair use applies.
- Readers who need a short rolling commitment, because the contract option runs 24 months.
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
T-Mobile Polska
How much does a T-Mobile Polska plan cost at the cheapest end?+
Plans start at PLN 30 per month on the prepaid card. The reference tariffs add GO! S and GO! M, a smaller and a larger data bundle billed monthly on a short cycle, so entry pricing stays flexible rather than locked. Unlimited data sits higher, at PLN 75 on the Abonament komorkowy plan.
What does unlimited data cost, and how long am I tied in?+
The Abonament komorkowy plan carries unlimited data at PLN 75 per month and runs 24 months. That is the trade-off to weigh: a lower entry price on the prepaid card tariffs, or unlimited data on a long contract. On that measure the brand ranks 59 of 173.
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.
