Unexpected call from +255?
If you have no contacts in Tanzania, a missed call from +255 that rings once is the classic "wangiri" pattern: the callback is billed at international or premium rates. Do not call back; look the number up instead.
Messages from foreign numbers offering jobs, investments or "a wrong number" chat are another common opener. A real +255 number can also be spoofed, so caller ID alone proves little — check whether the number is valid, which network holds it and whether it is a mobile, landline or VoIP line.
