1&1 Mobile is a telecommunications subscription delivered over the operator's owned or wholesale network footprint. Its product surface covers mobile or fixed-line connectivity in the operator's coverage area alongside monthly billing with no per-incident charges within plan limits, with the recurring subscription paid through the operator's direct billing or App Store / Google Play / partner-billing surfaces. Customers buy a tier matching their usage profile; the entry tier is suitable for testing the product and higher tiers add features such as mobile app for account management and top-ups.

Why choose 1&1 Mobile

Operator and ecosystem context

1&1 Mobile is run by 1&1 Mobilfunk GmbH out of Montabaur, Germany (parent United Internet AG Karlsruhe), established 1997 (1&1 brand); mobile launched 2009. That matters because the mobile plans category is increasingly consolidated and the operator's ownership structure (public vs. private, parent group, regulatory footprint) shapes how aggressively the product is supported and how stable the subscription terms are over multi-year renewals.

Plan structure and pricing tiers

The tier ladder splits across All-Net-Flat for testing the service, Smartphone tariffs with device for everyday use, and Data-only for power users or households. Anchor pricing for 2026: All-Net-Flat from EUR 9.99/month (with 5 GB) up to EUR 39.99/month unlimited. Consult Subger's true-price tracker for 1&1 Mobile for all-in renewal costs after taxes and FX conversion.

Network and connectivity features

Beyond the headline features, the 2025-2026 differentiator for 1&1 Mobile is 2024-2025 continued rollout of own 5G network (1&1 5G O-RAN Open RAN) — fourth German MNO; partnered with Vodafone for national roaming until coverage matures. That gives the subscription a credible roadmap for the year ahead and distinguishes it from operators that are running their mobile plans catalog on autopilot.
