Our verdict on each
Eni Plenitude
Eni Plenitude suits Italian households that want electricity and gas on a single fixed deal with an energy exit fee of €0. The tariff is listed at 100% renewable on a certificate basis, and the fibre broadband sold alongside gives a second reason to stay with one supplier.
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
Eni Plenitude
Pros
- The €0 exit fee ranks 1 of 29 brands, the clearest advantage in the set here.
- Renewable share of 100% on a certificate basis, so the green claim names how it is certified.
- Electricity and gas on the same account, electricity and gas, with fixed terms of 24 months if you want rate certainty.
Cons
- The €144 standing charge is the weak point, ranking 16 of 16 and sitting above the €14.98 market median.
- The fibre line carries a €39 setup fee, where the median setup fee across the plans listed here is €0.
- Broadband-only new customers pay €25.90 rather than the €19.90 rate offered with an energy contract.
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

sim.de
Who it suits

Questions about each
Eni Plenitude
Is there an exit fee on the energy contract?+
No penalty charge applies to the energy tariff, where the exit fee is €0. Broadband is treated separately: the fibre line carries a deactivation charge if you cancel within the initial period, and that charge is reduced when you hold an energy contract with the same supplier. Leaving the energy side is simple; leaving the fibre side is not free.
What do I actually pay on the energy side?+
The unit rate is €0.17 and the standing charge is €144, and the standing charge applies whatever the household uses. Low-usage homes feel that fixed part harder, so the same tariff can look different from home to home. Both fuels, electricity and gas, sit on the same contract.
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.
