Our verdict on each
Frontier Communications
Frontier Communications suits households in the US that want top tier fibre speed without a long contract, and it undercuts many rivals on entry price at $29.99. The catch is a setup fee of $100 plus a charge for leaving early on some promotional deals.
sim.de
sim.de suits people in Germany who want a cheap sim only line with a monthly option and a fixed contract choice on the same tariff sheet. It runs on the 1&1 network, and its entry price of €6.99 sits well under the market median for entry pricing.

Pros and cons
Frontier Communications
Pros
- Entry pricing of $29.99 sits in the lower part of our price table, and the reference plans come with no fixed term
- Top download of 7,000 Mbps and upload of 7,000 Mbps put it near the front of the speed table
- A current Wi-Fi router is included, and Whole Home Wi-Fi mesh comes on the gigabit tier and anything faster
Cons
- A setup fee of $100 lands near the expensive end of the setup fees we track
- Some promotional deals add a charge for leaving early, and disconnecting soon after joining means paying back part of the installation cost
- Service is confined to a single market, US, so it is not an option outside the US
sim.de
Pros
- Entry pricing of €6.99 is below the site median of €9.30
- The Unlimited on demand plan costs €19.99, under the site median unlimited price of €23.19
- Contract terms run 1 and 24, so a plan can sit on a monthly term or a longer one
Cons
- The Unlimited on demand plan is tied to the longer of 1 and 24, so unlimited data is not offered on a monthly term
- Service runs in DE only, so the tariffs are not offered outside that market
- As an mvno, sim.de sells on the 1&1 network rather than owning it, unlike the network operators getesa, yesss! and Lonestar Cell MTN
Who each suits
Frontier Communications
Who it suits
- Households in the US inside Frontier's fibre footprint, willing to accept a setup fee of $100 for a lower monthly price
- Anyone who needs gigabit speeds for large uploads, remote work backups or shared media
- People who want to leave without a long lock-in, since the reference plans run on rolling monthly terms
Who should look elsewhere
- Households outside the US, since service is confined to a single market, US
- Shoppers who want a cable package rather than pure fibre, since Astound runs cable and fttp
- People hunting for the very lowest entry price, since cheaper options sit below $29.99
sim.de
Who it suits
- People in DE who want a data heavy sim only line without paying for a handset
- Travellers from DE who want roaming included and reach across 33 countries
- Households that want one provider offering both a short monthly term and a longer fixed contract
Who should look elsewhere
- Buyers outside DE, since the service is a single market
- People who want a handset bundled with the tariff, as the plans are sim only
- Buyers who want unlimited data on a rolling monthly basis, since the Unlimited on demand plan sits on the longer of 1 and 24
Questions about each
Frontier Communications
What is the entry price for Frontier fibre?+
Plans start at $29.99 a month, and the reference tiers step up in speed from there to a multi gigabit option at the top. Every one of them is sold on rolling terms, so the monthly figure is the number to compare against rival quotes. Speeds, not term length, are what separate the tiers here.
Do I have to sign a contract with Frontier?+
No. The reference plans, from the entry tier through to the multi gigabit tier, are all sold without a fixed term, and the listed contract length is a rolling monthly term. That leaves you free to cancel without counting out a period first, which suits anyone who expects to move or switch.
sim.de
How much does a sim.de sim only plan cost to start with?+
The cheapest way in is the entry data plan at €6.99 per month, and it can run on a monthly term rather than a long contract. The larger data plan and the Unlimited on demand plan sit on the longer of 1 and 24 instead.
How much is unlimited data on sim.de?+
The Unlimited on demand plan costs €19.99 per month, and it is tied to the longer of the contract options, 1 and 24. That price sits under the site median unlimited price of €23.19, but the commitment is the part to weigh.
