What Are the Best SIM Cards in Germany? (2026)

By Jules de Bruin, Market ResearcherUpdated August 17 2026 | Found helpful by 4 others

The best SIM card for most people in Germany is fraenk at EUR 10 a month for 25 GB on the Telekom network, because it bills by calendar month rather than every 28 days. The cheapest way in is a supermarket brand such as ALDI TALK at EUR 8.99 for 25 GB, and the most data per euro is SIMon mobile flex at EUR 9.99 for 50 GB on Vodafone. None of them needs a German address or bank account, but every German SIM needs an ID check before it activates.

Which SIM Cards Are Worth Buying?

Seven tariffs, spread across all three German networks so there is an answer whichever one covers your address. Every card links to the provider's own site so you can check the price before you buy. Watch the billing cycle line: five of the seven renew every 28 days, which is 13 payments a year.

fraenk 25 GB

4.5

Best Overall. 25 GB with unlimited calls and SMS on the Telekom network for EUR 10, billed by calendar month and cancellable monthly, so there is no thirteenth payment.

Every SIM Card We Compared

We compared 239 German mobile tariffs and eSIMs across Telekom, Vodafone, O2 and 1&1, their value brands congstar, fraenk, SIMon mobile, otelo and Blau, the supermarket brands ALDI TALK, Lidl Connect, Penny Mobil, ja! mobil, Kaufland mobil, EDEKA smart, NettoKOM, Norma Connect and ROSSMANN mobil, the international specialists Lyca Mobile, Lebara, AY YILDIZ and Ortel Mobile, and the travel eSIM brands. The full catalogue lives on the price research page.

How Should You Pick a German SIM Card?

No address yet

Every prepaid tariff here works without a German address or bank account. What none of them skips is the ID check: have your passport ready for VideoIdent, which runs 24 hours a day.

Best coverage

fraenk and congstar ride Telekom, SIMon mobile and Lidl Connect ride Vodafone, ALDI TALK rides O2. You get the host network's signal, so pick the network first and the brand second.

Most data

SIMon mobile flex gives 50 GB for EUR 9.99 on Vodafone. Telekom MagentaMobil Prepaid also rolls unused data into the next cycle, which the discounters do not.

Already have an address and a SEPA account

Contract tariffs open up: O2 Mobile S at EUR 19.99 for 15 GB is the cheapest network-brand contract, and 1&1 sells 50 GB for EUR 14.99. All of them run a SCHUFA credit check.

How Much Does a German SIM Card Cost?

The prepaid floor is EUR 8.99 for 25 GB at the supermarket brands and EUR 9.95 to EUR 10 at the value brands and the networks' own prepaid tariffs. Contract tariffs start at EUR 14.99 from 1&1 and EUR 19.99 from O2, and the Telekom and Vodafone ladders run from EUR 29.95 and EUR 29.99 up to EUR 84.95 and EUR 79.99 for unlimited.

Add the one-off costs. A prepaid starter SIM is usually EUR 9.95 to EUR 9.99 and normally comes with EUR 10 of credit, so it is close to free; fraenk, SIMon mobile and Vodafone CallYa charge nothing for the SIM. Contract tariffs from Telekom, Vodafone and O2 add a connection fee of about EUR 39.95.

Then check the cycle. A tariff billed every 28 days renews 13 times a year, so EUR 8.99 is really about EUR 9.74 a month and EUR 9.95 is about EUR 10.78. Only fraenk and SIMon mobile in this ranking bill by calendar month.

Which Network Covers Your Area?

Germany has three physical mobile networks: Telekom, known as D1, Vodafone, known as D2, and O2, run by Telefónica. 1&1 is building a fourth and falls back to Vodafone national roaming where its own grid is not yet up. Every other brand on this page is a reseller on one of those, so the network behind the SIM matters more than the name on it.

Telekom is the best-rated German network in the connect 01/2026 test and in Ookla's Q1 to Q2 2026 measurements. O2 holds the highest measured 5G availability in Germany (Ookla H1 2025), but its rural coverage still trails Telekom and Vodafone. If you live outside a city, that single sentence is the whole decision: buy a tariff on Telekom or Vodafone masts.

How We Compared These

What we scored

We ranked tariffs on ease of buying, which network carries them, price per gigabyte, billing cycle, contract flexibility and English support. The weighting favours tariffs a newcomer can actually activate in their first week, which rules out anything needing a SCHUFA check.

Where the prices come from

Every figure was read off the provider's own page or a dated German price source in August 2026, not from an aggregator. Network quality claims come from the connect 01/2026 test and Ookla's measurements, named on the product they belong to.

How we get paid

Some links earn a commission. The ranking was set before the prices were collected, and no provider pays for placement or sees the ranking before it publishes.

Sources: connect 01/2026 network test, Ookla Speedtest measurements Q1 to Q2 2026 and H1 2025, provider tariff pages, accessed August 2026. Next review: November 2026.

Frequently Asked Questions

What is the best SIM card in Germany for most people?

fraenk, at EUR 10 a month for 25 GB with unlimited calls and SMS on the Telekom network. It bills by calendar month and is cancellable monthly, so there is no thirteenth payment, it supports eSIM, there is no SIM card fee, and the catalogue rates its English support as full. The trade-offs are real: it is app-only with no hotline and no shops, data is capped at 50 Mbit/s, and international calls from Germany are blocked entirely.

What is the cheapest German SIM card with a real data allowance?

EUR 8.99 for 25 GB with unlimited calls and SMS, sold by the supermarket brands: ALDI TALK and NettoKOM on the O2 network, Lidl Connect on Vodafone, and Penny Mobil, ja! mobil, Kaufland mobil and ROSSMANN mobil on Telekom. All of them bill every 28 days rather than monthly, which is 13 payments a year and works out at about EUR 9.74 a month.

Do you need ID to buy a SIM card in Germany?

Yes. Every tariff in this catalogue requires identity verification before the line activates, so there is no anonymous prepaid SIM in Germany. VideoIdent works with any passport, 24 hours a day, and activation can take anywhere from minutes to hours afterwards. SIMs bought from a vending machine still have to be verified online before they work.

Do you need a German address or a German bank account?

Not for prepaid. Every prepaid tariff here is marked as needing no German address and no German bank account. Contract tariffs are the opposite: they need a registered address, a SEPA direct debit and a SCHUFA credit check, which is why almost no one gets one in their first week.

Why is a German prepaid tariff billed every 28 days?

Because the cycle is a period, not a calendar month. A 28-day cycle renews 13 times a year, so ALDI TALK at EUR 8.99 costs about EUR 9.74 a month and MagentaMobil Prepaid M at EUR 9.95 costs about EUR 10.78. Only fraenk and SIMon mobile in this ranking bill by calendar month, and that is worth roughly one payment a year.

Is EU roaming included?

Yes, and on every tariff ranked here the roaming allowance matches the domestic one, so 25 GB at home is 25 GB across the EU. Telekom and congstar additionally treat data used in Switzerland like EU data.
