Our verdict on each
Enel
Enel suits Italian households that want a no-strings electricity plan and a single bill covering gas as well, and its €0 exit fee ranks at 1 of 29. The weaker measure is the standing charge, which places 7 of 16.
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
Enel
Pros
- Exit fee of €0 puts Enel at 1 of 29 on leaving early, so switching the energy plan carries no charge at all.
- Unit rate of €0.11 ranks 3 of 23, which keeps the cost of each unit low against the suppliers compared here.
- Tariff types run fixed and variable with fuels covering electricity and gas, so a household can take light and gas from a single supplier on one account.
Cons
- Standing charge of €12 places Enel at 7 of 16, so a light user pays more of the bill through the fixed charge.
- Tariff types are limited to fixed and variable, so anyone after a dynamic or green option can compare Powerpeers, which lists dynamic, fixed and variable.
- Fuels cover electricity and gas and the fixed and variable pairing carries no prepayment or electric vehicle option, unlike Electricity Ratings at fixed, ev and time of use.
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
Enel
Who it suits
- Italian households on IT who want light and gas from a single supplier
- Renters or movers who would rather leave a plan without an exit fee of €0
- Heavy users of electricity who gain more from a unit rate of €0.11 than from a low standing charge
Who should look elsewhere
- Households wanting a time-of-use or electric vehicle tariff, which Endesa offers through fixed, time of use and ev
- Buyers who want a dynamic or green option, which Powerpeers lists at dynamic, fixed and variable
- Anyone comparing only on tariff variety, since Electricity Ratings spans fixed, ev and time of use against the fixed and variable listed here
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
Enel
What does Enel charge to leave an energy plan early?+
The exit fee on Enel's energy plans is €0, so leaving before a term ends costs nothing on the light and gas side. That is unusual among the suppliers compared here, and it matters most to renters and to anyone who expects to move during a term. Broadband from the same company runs under its own separate terms.
How do the unit rate and the standing charge work together?+
The unit rate is €0.11 and the standing charge is €12. The rate applies to each unit of energy consumed, while the standing charge is a fixed cost added whatever the usage. A household using a lot of energy gains more from a low rate, and a light user is more exposed to the standing charge, so both figures matter.
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.
