There are some changes to the Unlimited on Demand and All-Net-Flat tariffs.

1&1 Unlimited on demand

With 1&1 Unlimited on Demand, 1&1 customers can always surf, chat and email reliably, even with increasing data consumption. The tariff portfolio is now being expanded to include an XS and XL tariff. However, we would like to clearly point out that there is NO commission for marketing the 1&1 Unlimited XL tariff!

In the selected tariff, customers can simply click to access additional GB free of charge and as often as required. This means unlimited data volume and unlimited calls. If desired, the tariffs can be combined with a top smartphone.

1&1 All-Net-Flats

There are also changes to the 1&1 volume tariffs: The 1&1 All-Net-Flats XS-L now come with an increased data volume of up to 120 GB from €9.99/month in the first three months.

Tariff special: Do your customers already have a top smartphone and are looking for an attractive SIM-only tariff with a high data volume? Then 1&1 has the solution with the 1&1 All-Net-Flat 100: 100 GB for a permanent €19.99/month.
