Hi, I have traveled to South Korea, and my phone is not connected to any network service, including calls, SMS, data, everything. I haven't even received the automatic SMS from Odido ever since I arrived in South Korea. So I think no service is provided right now. I have several SMS to receive from the Netherlands, which is really important and urgent to me. Furthermore, due to this issue, I cannot even do the two-step authentication. I already tried restarting; my roaming is on; and I already tried connecting to another network provider too, but nothing changed. I did everything that I could try. Can you please help me to fix this situation? Please answer the question as soon as possible, because I really need to receive the SMS within a few days. Thank you in advance.
