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.
BreezeSim
BreezeSim suits travellers and expats who want prepaid eSIM data rather than a handset contract, with plans starting at €4.95 and coverage across 190 countries. The trade-off is data that does not roll over and support running on chat, email and help centre, from a company registered in the United Kingdom.

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.
BreezeSim
Pros
- Sim only plans start at €4.95 on prepaid billing, with no handset in the bundle.
- Coverage spans 190 countries, and eSIM, 5G and hotspot sharing are all included.
- A multi line discount is available for extra lines on the same account.
Cons
- Data rollover is not offered, so unused data is lost when a period ends.
- Support runs on chat, email and help centre only, with no phone line listed for urgent problems.
- The Explorer pass is sold on 12 month terms paid upfront, which is heavy for a short trip.
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.
BreezeSim
Who it suits
- Frequent travellers who need data in 190 countries rather than on one home network.
- People who want a sim only eSIM and nothing tied to a handset.
- Households running extra lines, since a multi line discount is available.
Who should look elsewhere
- Buyers chasing the lowest entry price, since co:sim lists $0.99 against BreezeSim's €4.95.
- Shoppers who prefer to buy through a reseller, since ESIMZON and KnowRoaming list reseller and reseller where BreezeSim lists mvno.

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.
BreezeSim
How much does BreezeSim cost when I start a plan?+
Plans start at €4.95 on prepaid billing, and the cheapest option overall is a Europe eSIM bought as a monthly prepaid plan with 5G where available. There is no separate introductory and renewal split to weigh here: you pay for the plan you choose, while the Explorer pass is sold on 12 month terms and paid upfront.
Do unused data roll into the next period?+
No, data rollover is not offered, so anything left at the end of a period is lost rather than carried into the next one. That matters most on a longer pass such as the Explorer pass sold on 12 month terms, where a quiet month leaves you with less than you paid for. Size the pass to your heaviest travel period and treat the rest as gone.
