Why is my phone sending texts automatically?

[MrBander]

Why is my samsung galaxy s4 phone sending texts automatically (without asking) every time when i switch on my phone and reduce my balance?

Are those messages sent to some one in your contacts list or it's an unknown number?

 

[MrBander]

Unknown numbers, and every time about 10 messages

That's strange and a bit suspicious. First I would check with your network provider. Take it to their shop and see if they can find out what's going on.

Is it a personal phone or from your company?

A couple of thoughts. What kind of text is being sent in those sms? Have you noticed any other strange behaviour in your phone?

Personal phone. I called Vodafone customer service and they told I sent a lot text, but i did not find them in my mobile. They recommended to change phone. I did it. And with the Nokia N8 no problem. Working very well.*

I found the solution. It was a security program: Avast Anti-Theft. I set the program a long time ago, send me text message to my Hungarian mobile phone if somebody exchange the sim card. When I exchanged my sim card I got messages initially, but couldn't open it. I didn't know what is that and why. I uninstalled the program, and discontinued the problem.
Thanks your assistance.
