I received a text message yesterday and sent my bank card number and other personal information, and downloaded the software, but did not install and activate it. Will it cause financial losses?

Don’t believe it. Check the number that sent the message, and then call the bank to verify whether the number belongs to their bank. If so, ask for details. If the bank’s answer is different from The content of the text message matches and is basically credible. Otherwise, be careful, let alone downloading software. Opening this kind of text message may be dangerous
