Hack

Katiek2001 Said:

"I am concerned about somebody being able to hack into my phone , after almost being scammed[...] The only information the scammer had access too was my phone number and first 3 letters/numbers of my post code. Can somebody access my phone with this amount of detail?"

Modify your Credentials:

No one is viewing your screen. But, having fell for a scam, security is of high concern here. So, maybe use a new phone number. But most certainly, consider performing the following:

• modifying your login credentials (New eMail and New Password)
• associating a different method of payment to your account
• enabling Two-factor authentication for Apple ID and all other accounts, that have such an option

Can somebody access my phone with this amount of detail?

No. Absolutely not. You were not hacked and you will not be hacked, unless you give the phishing scammers all the necessary info. Just use common sense.

Recognize and avoid phishing messages, phony support calls, and other scams:
