Our verdict on each
EarthLink
EarthLink suits US households that want symmetrical fibre with no long minimum term, with upload speeds of 5,000 Mbps and plans listed at 1 month. The catch is what sits around the plan: Leased router $15.00 per month, plus data caps of 15 to 300 GB on the satellite tiers.
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.

Pros and cons
EarthLink
Pros
- Upload of 5,000 Mbps matches download of 5,000 Mbps, and that pairing ranks 7 out of 46 compared brands.
- Rolling terms at 1 month mean little to serve out if you move home, unlike a fixed minimum term.
- The entry fibre tier sits at $24.95 a month on month-to-month terms, with the gigabit tiers priced by address.
Cons
- Hardware is a recurring extra: Leased router $15.00 per month sits on top of the plan price every month.
- The entry rate is introductory only: 12 months consistent rates then full-price plan.
- Satellite tiers are metered, with data limits of 15 to 300 GB for heavier users to watch.
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.
Who each suits
EarthLink
Who it suits
- Households in US on fibre who send large files, back up to the cloud or run video calls upstream.
- People who prefer short commitments, with plans listed at 1 month.
- Remote workers and creators who judge a connection on upload, since 5,000 Mbps upstream matches the download figure.
Who should look elsewhere
- Astound, if cable alongside fibre matters, since Astound lists cable and fttp while EarthLink's list is fttp, 5G and satellite.
- Kinetic, if you want a straightforward fibre-only supplier, since Kinetic lists fttp.
- Abissnet, if a single-technology provider suits you better, since Abissnet lists fttp and EarthLink carries a wider fttp, 5G and satellite range.
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.

Questions about each
EarthLink
How much does EarthLink broadband cost at the entry price?+
The entry fibre tier is $24.95 a month on month-to-month terms. The gigabit and multi-gigabit tiers above it are priced by address, so what you actually pay depends on the fibre available at your street. Get a quote for your address before putting it against other offers.
Does the entry price stay the same after the introductory period?+
Not necessarily. The published rate is introductory: 12 months consistent rates then full-price plan. The figure you sign up on is therefore not the figure you keep, and the full-price plan rate takes over once the consistent-rate period ends. Budget for a higher monthly amount beyond that point.
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.
