So I have used the Samsung Galaxy s5 for like the last 10 years. Mostly for the fact that you can you can replace the battery on its own and the battery lasts forever. For some reason I can't make calls. I cant even call 911(Yes i tried). It dials and drops the call. I thought maybe my phone was just screwed up so I bought another s5 and put my sim card in and it does the same thing.Part of me wonders if it isnt because of the VOLTE thing.
