Suspicious texts purporting to be from O2

[ChrisOsb]

I am getting texts from 020 3475 6613.  Message states this is a call alert from O2 and then gives instructions on how to disable this alert.   Is this a scam?

@ChrisOsb That is not an O2 number.

Block the number and report it free to 7726.
Don’t open any links or enter any information.
