I bought Samsung unlocked Note 9 N960U1. But it did not work in Indian network. It works on LTE. But not supporting VOLTE. I am really frustrated after trying for a month to Samsung service centers and network providers. I have tried using different sim of VODAFONE, JIO, AIRTEL and IDEA. But no results. A phone cost 1000$ without supporting a basic need. I need to install an app to call. My current IPhone SE which is US unlocked works fine here in India. I called customer care and he told, there may be software update which will resolve the issue. Will you be able to solve in coming update?
