# What Are the Best SIM Cards in Germany? (2026) > Best SIM cards in Germany for 2026: fraenk, ALDI TALK, SIMon mobile, congstar and the Telekom, Vodafone and O2 prepaid tariffs compared on price, data, network and billing cycle. By Jules de Bruin · URL: https://www.guide-germany.com/telecom/sim 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 4.5Best 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.

The full catalogue lives on the [price research page](/telecom/sim/complete-market-and-price-overview). [View all 239 plansThe tariff picker lists every named tier from every provider with its allowance, price and EUR per GB, filterable by situation and re-rankable.→](/telecom/sim/complete-market-and-price-overview) ## 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](/finance/open-bank-account). ## 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](/telecom/prepaid-vs-postpaid). 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](/telecom/best-mobile-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.

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. --- Source: https://www.guide-germany.com/telecom/sim Last updated: n/a Format: LLM-readable Markdown twin (.md) of the canonical HTML page.
