I have an iPhone 6 running iOS 10.3.1. I use two sim cards and when I swap them, I noticed that the balance gets lower, every single time.
This looked fishy, so I contacted telecommunications company, and they sent me the last 5 deals and I discovered that they all were messages sent from the phone to an international number
447786205094, and I checked it many times, and every time I swapped the sim card the phone always sent a message to the previous number.
I made sure that
Facetime are disabled.
What is happening here?
