Sometimes, an incoming call shows up as \u201cUnknown\u201d or \u201cHidden number.\u201d You can\u2019t call back, can\u2019t see the number, and have no way to identify the caller. These calls might happen once or keep repeating \u2014 but the question remains: how can you know who\u2019s calling? <\/p>\n\n\n\n
One way to reveal the caller is by setting up call forwarding \u2014 either to voicemail or to another number. In some cases, this can expose the original phone number, especially if the call isn\u2019t answered right away. In practice, forwarding to a number from a different mobile carrier tends to work more reliably. <\/p>\n\n\n\n
\u2757 Important: <\/strong>Most carriers charge for call forwarding. Always check the terms, including pricing and billing details, before activating the feature. <\/p>\n\n\n\n If the forwarded call reaches a phone with NumBuster installed, the number is instantly checked. The app shows how often the number has called, whether it\u2019s been flagged by other users, and what comments have been left. This makes it easier to tell whether the number belongs to a call center, a marketing team, a company employee \u2014 or someone with a questionable track record. <\/p>\n\n\n\nHow NumBuster helps <\/h3>\n\n\n\n
