  5. Under "Basic configuration" you can change the sender ID with the following four options: Changing the sender ID to an already verified FACT24 callback number (+44 20 35 64 98 55), to the FACT24 number for 2-Way-SMS (+44 78 60 03 70 21), to your own number or from July 26th 2923 on to an alphanumeric sender ID.
