About happy-sim.de
Happy SIM sells mobile phone tariffs in Germany. Each plan includes an all-network flat for calls and SMS, 5G internet of up to 50 Mbit/s and EU roaming, with data volumes from 25 GB to 100 GB per month. The service runs on the Telefónica mobile network.
Customers choose between a 24-month contract and a monthly cancellable plan, and can switch, upgrade or cancel tariffs. Tariffs are sold online, with a one-time connection fee on some plans and a monthly fee as the main revenue source. Customers can keep their existing phone number when switching and pick an activation date up to 90 days in advance.
The company states that monthly prices stay the same after the first 24 months of a contract.
