Pros and cons

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
  • Roaming is included and covers 33 countries, with EU roaming part of the tariff
  • Sim only lines, 5G and an Esim are available, and support runs on email, chat and phone

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
  • Entry pricing ranks 132 of 258, so cheaper entry offers sit elsewhere on the site

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

What it does well

sim.de sells sim only lines, so you bring your own handset and pay for network service rather than for a phone. 5G is available on the tariffs, which puts the faster generation inside the offer rather than behind an upgrade. An Esim is available alongside the physical option, so a line can be activated without waiting for a card in the post. That suits anyone replacing a handset quickly, or carrying a spare device while travelling. Roaming is included, and the roaming reach covers 33 countries. EU roaming sits inside the tariff, so a trip inside Europe does not mean buying a roaming package or a second line. The same company also sells fixed line broadband, which is worth a look if you want one supplier for mobile and home internet.

Where it sits among rivals

Entry pricing tells one story and unlimited pricing tells another. On entry pricing, sim.de sits at 132 out of 258 brands, which places it well down the field. On unlimited pricing it ranks far higher, at 68 out of 173. The same pattern holds inside the categories sim.de appears in. The median entry price for sim only deals is €6.99, and the median unlimited price is €23.24. A middling rank on entry paired with a high rank on unlimited data suggests reading the whole tariff sheet rather than the cheapest line alone. That matters most for heavy data users, who feel the unlimited figure every month rather than the entry price.

Pricing

Reference plans are listed by data allowance. The entry data plan is €6.99 per month and can be set up monthly. The larger data plan costs more each month and sits on the longer of the contract options, 1 and 24. The Unlimited on demand plan is €19.99 per month, and it also sits on the longer term. That split is the trade-off to weigh. The smallest outlay comes with a monthly option, while the bigger allowance and the unlimited plan are priced across a longer commitment. The comparison that matters is the data allowance set against the length of the term, because the monthly plan and the longer term plans are not the same price. Billing is offered as a contract and as rolling, so the same tariffs can be set up with a fixed term or without one.

Who runs it

sim.de is run by Drillisch Online GmbH, which is based in Germany. The company was founded in 2014, so it is a young provider rather than one of the long standing operators in the market. It sells as an mvno on the 1&1 network, which is the usual route to tariffs priced below what a network operator charges. The trade-off is reach, since the service covers DE only. Support runs on email, chat and phone. Phone, email and live chat are all available alongside a help centre, so a question about a tariff or a bill can go to whichever channel suits.

How sim.de compares

Frequently asked questions

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.

Is roaming included on sim.de plans?+

Roaming is included on the tariffs, and the roaming reach covers 33 countries. EU roaming is part of what you get rather than an add on, so regular travellers from DE can keep the same plan instead of buying roaming credit separately.

Which network does sim.de run on?+

Service runs on the 1&1 network, and sim.de is an mvno, so the tariffs are priced by sim.de while coverage comes from the host. Coverage in DE only means the plans are not offered outside that market.

Can I get an eSIM from sim.de?+

An Esim is available, alongside sim only lines and 5G. It comes off the same tariff sheet as the physical option, so the entry price of €6.99 applies either way and there is no separate eSIM rate to track.

How long is the contract on a sim.de plan?+

Contract terms run 1 and 24, so a plan can sit on a short monthly term or a longer one. Billing is available as a contract and as rolling, which means the same tariffs can be set up with or without a fixed commitment.

Who is behind sim.de?+

The provider is Drillisch Online GmbH, based in Germany and founded in 2014. It is a young company rather than a long established operator, and it sells as an mvno on the 1&1 network from DE.

How do I get help from sim.de?+

Help is available on email, chat and phone, so you can pick phone, email, live chat or the help centre. Having a phone line and a chat option together is useful when a billing question needs an answer quickly.
