g On the basis of different rulings on the expiry of prepaid credit and the limited validity

of prepaid cards, T-Mobile Deutschland changed its terms of contract and thus also its

deactivation policy in the first quarter of 2007 in favor of its prepay customers. These

customers can now use their prepaid credit longer than before. As a result of the change

in the terms of contract, prepaid contracts no longer end automatically, but run for an

unlimited duration and can be terminated by the customer at any time and by T-Mobile

with one month’s notice. T-Mobile Deutschland reserves the right to make use of this right

of termination and to deactivate cards in the systems.
