congstar

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.

congstar

Pros

  • Entry pricing starts at €2, well under the €9.30 site median, with prepaid billing available through contract, rolling and prepaid.
  • No price rise - price stays as agreed, so what you sign up for is what you keep paying at renewal.
  • Terms run 1 month, short enough to leave without a long tie-in.

Cons

  • The largest reference plan, Allnet Flat L, is a capped data allowance, so constant streaming or heavy hotspot sharing meets a ceiling.
  • The entry figure of €2 belongs to a prepaid bundle, so the monthly contract option Allnet Flat S sits well above the €9.30 site median.
  • Support reaches chat, phone and help centre, where email is not among the listed channels.

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.

congstar

Who it suits

  • Households wanting one bill option across contract, rolling and prepaid types, from prepaid to contract.
  • Travellers in the EU who want roaming at included rather than paying per use.
  • People on the Telekom network who would rather buy through an mvno than go direct.

Who should look elsewhere

  • Anyone who needs truly unlimited data, since the congstar reference plans stop at Allnet Flat L; GETESA, listed as a network, is worth reading if you prefer a direct network tariff.
  • Those wanting a single monthly contract price, since the cheapest figure belongs to a prepaid bundle while Allnet Flat S costs more each month.

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.

congstar

How much does congstar cost to get started?+

Entry starts at €2, which sits below the €9.30 site median for this kind of plan. That figure belongs to the prepaid option, Prepaid wie ich will, on a short prepaid billing cycle. The contract option, Allnet Flat S, costs more each month, so the cheapest headline price and the monthly contract are separate products.

Will my monthly price go up when I renew?+

The stated rule is No price rise - price stays as agreed. Nothing in that rule allows the agreed figure to climb, which is the main thing to check before signing a contract option. Contrast that with typical market behaviour, where the €43 site median for a post-contract price sits well above the €9.30 entry median.
