I have an android phone with Tre subscription. For last 3-4 months I see International sms cost in my invoice. When I investigated those sms, I found that I dont know those numbers where sms was sent. I also realized that I never sent those sms. We ran the anti-virus on my phone and did not find any virus. When we checked with telecom provider they also did not have any clue. I checked that my phone and apps all are updated. I don’t know if any of the apps sent those sms without my knowledge. Has anyone faced such an issue? If so, were you able to resolve this?
