I purchased a phone in the United States and gave it to my mother to use it in Hungary. She put her own Sim card in it from her other phone. I created an Avast account online for her. I set this new phone as a trusted phone, but still every time she turns on the phone her sister gets the text message about an untrussed phone and change of location which cost EUR 0.15 every time for my mother . I deleted her phone from the account . Now there is no phone on that account at all . But her sister still gets the text messages for EUR 0.15 each . I called customer service here . But the representative told me he won't talk to me only to my mother . I told him, she doesn't speak English and the representative doesn't speak Hungarian, I created the account and the device is mine, I just gave it to my mother to use it, but he didn't care. He was extremely rude, he even raised his voice at me . I have never experienced such a rude, horrible customer service . I don't know what else to do. When I created this account it didn't say that It won't support device in other countries . I deleted my mothers device from the account, but it still didn't help . And there is no help from overseas or here in the U.S. I have another account with 4 more devices on it , but I will delete my account because of the horrible customer service .
