Hello,
*I didn't contact my service provider
*The message poping up for no reason
*I didn't try to remove my sim, but i will definitely try
*I own galaxy S22 ultra
Thank you for your help
I am having a trip outside my country, and I bought a local sim in sri Lanka, since then my phone giving me a pop up message evrey few minutes that say Callback service is unavailable, very annoying.
