Llamadas desde un móvil Yoigo que llaman de forma repetida, cuelgan y piden que te añadan a WhatsApp alegando un supuesto sorteo de TikTok. Usuarios califican el número como estafadores y describen llamadas continuas (varias seguidas) y la táctica de pedir agregarte a WhatsApp. No hay empresa legítima identificada; parece un intento de captura para un premio falso.

Likely purpose: Captación para un supuesto sorteo (TikTok) y solicitud de añadir a WhatsApp (posible estafa)
