AI Analysis

Limited but indicative information of suspicious activity. The number +34621405851 has been reported by several users in Spain for making silent calls or calls with beeps, with no one answering on the other end. Some users mention that the number may slightly vary (changing the last three digits) and that when trying to call back with the number hidden, a voice message is received indicating that the number does not correspond to any customer. These patterns are common in spam or phone scam campaigns.

Likely purpose: Spam or phone scam. The pattern of silent calls or calls with beeps, along with the number variation and the automated response when calling back, suggests malicious activity aimed at deceiving or harassing users.
