If text messages come every day, if your critical illness insurance is not activated, is it a scam?

Not necessarily, unsafe, not necessarily a fraud trap, but it is possible and there are great security risks.

You must have a sense of fraud prevention at ordinary times, otherwise it will be too late to regret being cheated.
