Kargono

Kargono is a German-language guide and comparison site focused on mobile data plans and connectivity. It helps readers assess internet-only SIM tariffs for smartphones, tablets, and other mobile devices, with practical guidance on data allowances, LTE and 5G access, network speeds, prices, and contract terms. Its articles compare selected offers across the Telekom, Vodafone, Telefónica (O2), and 1&1 networks, covering providers such as Deutsche Telekom, congstar, freenet, klarmobil.

de, Lidl Connect, and otelo. The site explains how to choose an appropriate data allowance, whether a short or long contract is preferable, and what happens when high-speed data is used up. Comparison tables list monthly costs, included data, maximum download speeds, and minimum contract periods, while highlighting restrictions such as fixed-address use or price increases after an introductory period.

Kargono also points readers to a tariff calculator for broader comparisons. Its content is designed to make mobile internet offers easier to understand and compare, rather than to provide the network service itself
