Frequently asked questions about suspicious calls
How to know if a phone number is spam?
Identifying whether a phone number is spam can be complicated, but there are indicators that can help you. Generally, spam numbers tend to have prefixes you do not recognize and are not in your contact list. It is also common for the call to come from numbers that start with international or special prefixes. If the call is from a number you do not recognize and you have no reason to answer, it is best to let it pass.
What does it mean when they call you and say “possible spam”?
When your phone operator warns you that a call is “possible spam,” it means that the system has detected calling patterns associated with numbers that have been reported as potentially fraudulent. This warning is a precautionary measure, and it is advisable not to answer the call. If it is important, the caller will leave a message.
How do spam numbers start?
Spam numbers usually start with prefixes that are uncommon in regular calls. Some examples include prefixes corresponding to distant countries or premium services. They may also use numbers that appear to be local but are actually fraudulent. If you have doubts about a number, search online to verify its origin.
What happens if you answer a spam call?
If you answer a spam call, the scammer may try to trick you into sharing personal or financial information. In some cases, they may simply hang up, but in other instances, they may continue calling persistently. It is always advisable not to interact and, if possible, block the number immediately after the call.
