Our verdict on each
Astound
Astound suits US households that want matching download and upload speeds, a low entry price and no contract to be tied into, and the same account can carry mobile lines. Entry pricing starts at $19.95 a month, Gig tiers arrive with Whole Home WiFi included, and the setup fee is $0.
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
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.
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
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.
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
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.
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.
