Annoyed! Seeking help! Team Truecaller, please reply! I use two SIM cards. I don't use SIM 2 for a phone call and don't want others to know that number. However, on one occasion Truecaller automatically made a call from SIM 2 without letting me know as there was a network issue with SIM 1 at that time. I couldn't find any option to stop automatically switching the SIM card. Is there any option? Please let me know.
