Our verdict on each
OiSTER
OiSTER is a rolling Danish MVNO that suits households wanting a month-to-month bill, sim only plans and an unlimited option at DKK 49 a month. It is a weaker choice than the cheapest listings on entry price, so buyers shopping purely on the headline figure should look elsewhere first.
TalkTalk
TalkTalk is the pick for households in Switzerland that want unlimited mobile data without a device deal, with the Swiss Deal plan priced at CHF 12 a month on a contract term. The trade-off is that the lowest entry point, CHF 1.95, is a pay per use plan rather than a full monthly tariff.

Pros and cons
OiSTER
Pros
- The unlimited Fri tale Fri data plan is listed at DKK 49 a month, which ranks 13 of 173 on unlimited price.
- Rolling billing at 1 month, with Basic available pay-as-you-go and no binding period.
- Sim only, eSIM, wifi calling and a multi line discount are all available, on 5G technology.
Cons
- The DKK 18 entry price ranks 43 of 258 on the listings compared, so entry pricing is mid-table rather than the cheapest on offer.
- The Fri tale plans are published at a promotional rate before a higher standard rate, so the ongoing cost on the same plan name is the figure to budget.
- Coverage is limited to DK, so residents outside that market have nothing here to switch to.
TalkTalk
Pros
- The Swiss Deal plan gives unlimited data for CHF 12 a month, so there is no monthly cap to plan around.
- Sim only and eSIM are both available, so the tariff can be paired with a handset you already own.
- EU roaming is included rather than sold as an add-on, and the roaming package covers 37 countries destinations.
Cons
- The headline entry price of CHF 1.95 belongs to the A la Carte pay per use plan, so it is not the price of an unlimited tariff.
- Unlimited data comes with a commitment: the plan terms available run 1, 12 and 24 months, which suits a settled household more than a short stay.
- Home internet runs on 5G and fwa with a setup fee of CHF 99, so the first bill is heavier than the monthly figure.
Who each suits
OiSTER
Who it suits
- Households in DK that want a rolling monthly bill and can cancel mobile broadband with notice.
- Readers who want unlimited data at DKK 49 a month rather than the cheapest possible entry price.
- Families running more than one line, since a multi line discount applies alongside eSIM setup for a new handset.
Who should look elsewhere
- Anyone who wants to buy from the network operator instead of an MVNO: GETESA, Lonestar Cell MTN and yesss! all sell as networks.
- Shoppers ranking purely on the lowest price from, since DKK 18 sits at position 43 of 258 and yesss! or GETESA belong on the same shortlist for that column.
TalkTalk
Who it suits
- Households in Switzerland that want a single provider for a mobile line and a home internet line.
- People who already own a handset and only need a SIM, with eSIM available for a quick switch.
- Travellers who want EU roaming bundled in rather than bought per trip, with 37 countries destinations covered.
Who should look elsewhere
- Readers who would rather buy from the network itself: GETESA and yesss! both sell as networks, while TalkTalk is an mvno on Sunrise.
- Readers who want one predictable monthly figure for heavy use: the CHF 1.95 entry price belongs to a pay per use plan, so budget the CHF 12 unlimited plan instead.

Questions about each
OiSTER
What is the cheapest OiSTER plan and what does it cost?+
The entry price is DKK 18 a month. Basic is the pay-as-you-go option, billed on usage with no binding period, so it works for light use and for anyone who does not want to be tied in. The two Fri tale plans sit above it, one with a capped allowance and one unlimited, so the entry figure suits a phone that lives mostly on wifi.
What will I pay when an introductory price runs out?+
The Fri tale plans are published at a promotional rate first and a higher standard rate afterwards on the same plan name, so the ongoing cost is the standard rate, not the introduction. Basic sidesteps that because it is pay-as-you-go. The unlimited plan, Fri tale Fri data, is listed at DKK 49 a month on the published pricing.
TalkTalk
How much does a TalkTalk mobile plan cost?+
Entry pricing starts at CHF 1.95 a month on the A la Carte plan, which is pay per use rather than a set data allowance. The Swiss Deal plan is the unlimited one, priced at CHF 12 a month. Both are sold on a contract term, though contract, rolling and prepaid covers the billing styles TalkTalk offers more widely.
Which contract lengths can I choose?+
Terms of 1, 12 and 24 months are available, so there is a short option as well as a longer commitment. The Swiss Deal plan that carries unlimited data is sold with a longer term, while the A la Carte pay per use plan holds the entry price of CHF 1.95 down for lighter users. Pick the term that matches how long you plan to stay.
