No synchronization of contacts possible

But one point is incomprehensible for me: the Speedphone 50 can not synchronize contacts. It offered no functional purpose. Even a synchronization via the mail account with Telekom or a simple vCard Import is not provided. Thus, the manufacturer is actually assume (after consultation with the telecom customer) that all contacts are entered manually.

So this phone is unfortunately not very useful. Alternatively, you have some time to plan, (hopefully without typos) entered all contacts in the phone or router.
