I've recently bought Xperia Z5 second hand and noticed that I can't send or recieve calls and texts. In Call barring settings all calls are disabled by default and can't be changed, Network or SIM card error. Problem is not in sim or network since any sim is not working in the phone but is working in any other phone. Sometimes I would be allowed to make a phonecall and then again blocked. It must be softwear problem. Tried reseting, restarting and PC Companion, nothing has helped. Any idea? Thanks
