Germany’s mobile phone market has specific characteristics that differ from other European countries. Here is a practical guide for newcomers.
The Network Operators
Germany has three major network operators: Telekom (Deutsche Telekom — the best network coverage, largest 5G footprint, most expensive), Vodafone (second in network quality, wide coverage, slightly cheaper than Telekom), and o2 (Telefónica, competitive on price, coverage weaker outside cities). Virtual network operators (MVNOs) operate on these networks and typically offer cheaper contracts: 1&1 (uses Telekom network), congstar (subsidiary of Telekom, same network at lower cost), Aldi Talk (uses Telekom), Kaufland Mobil (Telekom), and Lidl Connect (Telekom) for Telekom network at budget prices. For the best network at the lowest cost: congstar (monthly contracts, €9–25/month for basic to unlimited data, Telekom network quality).
Contract Types
Laufzeitvertrag (fixed-term contract): typically 24 months, includes a new phone at a subsidised price, cancellable only at contract end. Vertragsmodell ohne Handy (SIM-only contract): 24-month contract without hardware, lower monthly price. Monatlich kündbar (month-to-month): cancellable monthly, no long-term commitment, highest flexibility, slightly higher monthly cost than fixed-term contracts. For newcomers without credit history or certainty about how long they will stay in Germany: month-to-month contracts are strongly advisable. Prepaid (Prepaid-SIM): buy a SIM, top up as needed, no contract required. Aldi Talk, REWE Mobil, and Penny Mobil offer reliable prepaid on the Telekom network for €7–15/month for basic plans.
What the Plans Offer
German mobile plans compete heavily on data volume. In 2024–2026, most plans offer: unlimited calls and SMS (standard in virtually all plans above €10/month); EU roaming at the same rate (legally required for all EU plans); and varying data: 5GB (€10–15), 15GB (€15–20), unlimited data (€20–35 for good plans). 5G speeds are widely available in cities on Telekom and Vodafone; less so in rural areas. When travelling in Germany: Telekom’s coverage map is the most accurate indicator of rural coverage quality. The DSL vs mobile decision: Germany’s landline broadband is often slower than expected; many people in cities use a mobile plan with unlimited data as their home internet (USB SIM router, €30–50 for the device).
Practical Recommendations
For expats who want flexibility: congstar (month-to-month, Telekom network, €12–25/month for solid data plans). For the absolute cheapest with reliability: Aldi Talk prepaid on Telekom (€7.99/month for 3GB, available in any Aldi supermarket). For business use or reliable rural coverage: Telekom direct (MagentaMobil L, unlimited data, €55/month without discounts — expensive but the best network). For checking coverage before signing: use the coverage maps at bundesnetzagentur.de (the official regulatory map showing all operators’ stated coverage).
