How do i get o2 firmware installed on my Xperia Xa2 ultra? So I can use WiFi calling? Cos the signal is terrible, drops to no service all the time. But apparently its excellent indoors and out! So must be me and about 8 different phones that are not good enough
The best number to call on appears to be 0800 587 4005
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
