In the morning I finally updated my L521 Nokia phone with the long awaited Black/Gdr3 update. Everything went smooth there was no problems. All the features worked well. No trouble until I restarted. My phone...at first I had WiFi calling on my front tile which was working beautifully. Until after the restart that it disappeared. So I went to settings and enabled it but it won't work or show WiFi calling on the front tile. It just sais no service! To top it off I only put it so that I use cellular network on the WiFi calling settings and even when I did that there's problems sending text messages it keeps saying can't send SMS. Aand when i try making a call it sais no service this totally sucks. Anyone have this problem?
