I received a text from one of my contacts and they swear that they did not send it. Is this possible? We both have a samsung s20 + if that helps.
Although Caller ID spoofing is possible, it is usually used for calls and not text messages.
It would also be quite the coincidence that the number used for spoofing would be one that is saved in your contacts.
Did the content of the message look suspicious (links, asking for personal information, etc.)?
