Offer reserved for existing BASE customers 
Existing BASE customers are also entitled to this discount, but only if they have been a BASE customer for more than 3 months and if they can introduce a new BASE customer for a mobile contract of € 20/month, € 29 /month or € 39 /month. The discount applies to current tariff plans. If the existing customer has a different tariff plan, they will be transferred to one of the above tariff plans. Providing these conditions are met, the existing BASE customer will receive a € 5 discount on the monthly subscription fee in the case of a subscription of € 20 or € 29/month, or a discount of € 10 on the monthly subscription fee in case of a subscription of € 39/month, and this for the entire duration of the contract. The discount and, where applicable, the transfer will be allocated and/or implemented automatically as soon as the new customer’s SIM card has been activated. This must be completed at the latest 30 days after purchase.  If the new customer cancels their subscription, the existing customer won’t be automatically migrated back to the original plan. If the base price of the subscription is increased, the promotional price will also increase by the same amount. The existing customer loses his monthly discount if he cancels his subscription, migrates to a €15 or lower rate plan, or if the customer he introduced cancels his subscription. Action for existing customer cannot be combined with other offers and promotions, except with smartphone promo or the BASE+TADAAM discount.
