OK so I was on Plusnet for 3 years and moved to EE on their advice about a year ago. EE calls would often not work or the person calling me would go straight to voicemail. I noticed how 4G band would drop to E and I would require a network reset done by EE and things would temporarily work again. This has been done multiple times in the last year.
I called up tech support level two recently and they advised settings called IMS was not setup right which is required for 4G communication networking he advised me to factory reset the phone which I did and after this 4G calls were allowed to go through, confirmed several days later by the same tech guy. The phone stopped working again just days later and after doing some reading, I discover that the SIM card slot itself may have issues and so I tried using SIM slot 2. I now get success in that my phone calls work fine, except for the fact caller ID is not showing on incoming calls. It's been called by two mobiles and a landline multiple times and it does not show who is calling, despite that number being in the contacts list. When I called the phone with the SIM in slot 1 caller ID comes through but I cannot take the call as it drops out again from 4G to E. The handset is Xperia 10 III with Android 13, all updates applied.I have used the phone with my sisters 3G SIM in and it worked fine.
I find the tech support absolutely useless with EE, at least two level two techs have not responded to my emails and every time I speak to someone I have to go over everything again. I was told recentlty to replace the SIM and it temporarily worked again, why wasn't I told to try this last year? Another issue, the level two tech guy who noticed 4G coms wasn't installed their end, why didn't the tech guy I spoke to two months ago check this? I explained the whole 4G drops to E a year ago so why didn't they look at that in better detail back then?
Thanks in advance.
