Here, we expose the techniques Sim-swap fraudsters put and clarify how-to secure yourself.

How your number are hijacked

Is cellular networking sites undertaking adequate to end Sim-swap fraudulence?

Should you enter a phone store and request an alternative Sim card, staff members should request the passport or travel licence, although a 2018 BBC Watchdog research discovered that staff members don’t always stick to authoritative procedures.

We noticed furthermore dubious tries to access Ms Fowler’s membership and put an additional coating of security by requesting a computer program bill as more proof of ID.’

‘We instructed Ms Fowler to contact the lady bank immediately and that helped prevent unauthorised access to the woman banking account.
