Unbeatably independent: with the prepaid SIM card without contract binding, stay flexible with full cost control. The triple SIM can be used with Standard, Micro & Nano formats. (Not for smartwatches, kidswatches.)
Starting credit and other options: charge online, via the MeinMagenta app or via charging code. Optionally, additional data volume can be booked. With your prepaid card, you will receive 10 € starting credit.
PERMANENTLY MORE DATENVOLUMEN AND AT THE SAME PRICE. Monthly 13 GB high-speed volume - always at maximum available speed and best network coverage (LTE Max/5G). The prepaid annual plan contains unlimited calls and texts in the Telekom mobile network and in all other German networks.
NEW ROAMING CONDITIONS INCLUDED: With EU-Basic Roaming, making calls and surfing abroad is now even easier. And even cheaper. Use your included volume for temporary stays in the EU, UK and Switzerland at no extra cost.
NEW AND SIMPLY FAIR: Because unused data volume is automatically taken into the next billing cycle and consumed fairly first. Simplified roaming at better conditions and a higher SSD speed of incredible 64 kbps make MagentaMobil prepaid rates even more attractive.
