Since installing the 48.1.A.2.50 update that was released a couple of days ago, my XA1's cellular service has been completely unusable, phone calls, text, and mobile internet. Wifi is fine, but I am unable to make or receive phone calls. Have tried manually entering the carrier's settings (GiffGaff), but to no avail. The sim card and its settings work fine in other phones, so I know it's my Xperia XA1 that is causing this issue. I've read through the forum, and seen similar issues, but they were for different updates, and different models (XA1 Ultra, XA1 Dual Sim, etc.,). Really need my phone service back asap, as I'm currently in the thick of job-interviews!
