https://community.sony.pl/t5/z-series/xperia-z5-premium-signal-problem/m-p/3607101#M119268 <P>Hello. I recently bought a brand new Xperia z5 premium off eBay.</P><P>everything seemed to work great but I soon realized I cannot make or receive any voice calls. I could however send/receive texts. Every time I try to call, it hangs in calling until the phone drops the signal and the call ends itself. When I try to open the call forwarding/bar settings, it says network/SIM card error with loss of signal. In fact, the signal is lost most of the time. I tried different SIM cards as well but same symptom. I also tried Xperia Companion software fix and factory reset numerous times.</P> Sun, 27 May 2018 14:12:45 GMT Vertici 2018-05-27T14:12:45Z https://community.sony.pl/t5/z-series/xperia-z5-premium-signal-problem/m-p/3607101#M119268 <P>Hello.
