Expert from the portal Niebezpiecznik have received messages from their readers in which owners of phones running Android and iOS were concerned that their smartphone “sent out SMS’ to a strange Polish number”.
In this situation, you would expect they are premium SMS’ or a virus.

Niebezpiecznik reassures that the phone had not been hacked in this case.

If the phone sends an SMS to one of the following numbers:
732232988, 732232988, 732232986, 732232984, 732100230 with the text:
- Google is verifying phone # of this device Learn more: https://goo.gl/LHCS9W

It means that it is standard verification of the phone number listed under user’s Google account to confirm ownership. This applies to users that gave Google permission to do so during the account setup process. The cost of the SMS falls under standard rate for your operator.
