### 5/5 — La solución a mi sufrimiento: el spam telefónico

*2026-03-20*

En México hay muchas llamadas de spam de Telcel y ya me tenían mal pues era de todos los días.  Inician con 998 /999 / 983… las estuve bloqueando desde mi iPhone pero como tienen miles de números pues el iPhone solo bloquea cuando el número se lo doy completo y no por el prefijo como lo hace esta app. Y no podía bloquearlos tampoco a través de Profeco. Así que muy bien por esta app que hizo todo el trabajo. Ya puedo trabajar tranquilamente sin que me llamen a cada rato con su horrible spam.
