How can i know , if my phone is sending this sms. I havent been able to see these said messages. After buying the phone , i have travelled internationally and used it in at least two countries . I still havent noticed any drop in my account balance. If it was sending messages , i would have at least noticed when i was on international roaming. Is there any logs or sent messages folder which i can check to see if this is happening. Or is this occurring to only few phones?
