Sudden Drop in 5G signal and performance

Cross post from broadband forum as affecting all my devices.

Hi all,

Looking for some advice. I have a ZTE home router and a few 5G enabled mobiles. Recently, the performance on all of them has fallen. Typically I used to get over 300/25 via my home router and similar, if not faster on my mobile, but now this performance has dramatically fallen, with typical speeds of 60/5, and now 40/2. The placement test on the ZTE has gone from "excellent" to "poor" without any change in its position. My 5G phones all never report the same speeds they used to

Looking at Cellmapper, I am connecting to a mast that is around 300m away (straight line distance) I am not sure if this is the mast I used to connect to, but I would be surprised if it was not. I think there is a mast further away that the devices sometimes flip to that then causes performance to dramatically increase. There are apparently working going on in that location.

My suspicion is that the mast is now oversubscribed and this is why my performance has dropped so significantly. I have also noted on cellmapper that the coverage fields projected from the mast now no longer cover my road. I think they used to before. Finally, my router now only seems to connect to a 4G network:

4G Frequency: 99
4G Connected Band10.0MHz@2100(B1) + 20.0MHz@ + 15.0MHz@1800(B3)
4G Signal Strength-99 dBm
4G ECIO/SINR2.6 dB
4G PCI4
4G Cell ID784967

All fields relating to 5G are blank.

Seeing as I am stuck in a contract that is now not delivering, is there anything that I can do to try and restore performance before I look into potentially having it out with Three. I have already submitted a complaints form. Any other ideas are welcomed

Ok, accepted the SIM number when I changed the drop-down option from Home Broadband, which is what I have the issues with, to pay monthly!

Although you may wish to, cancelling your Direct Debit in protest is likely to affect you more than Three as mobile operators will register it as a default which can cause issues if you are looking to apply for any sort of credit or a mortgage and they may even hand it off to a debt collection agency.

I was a moderator on a mobile related forum for a while and saw this happen a number of times so really don't do it.

Go through the complaints procedure instead.

All service providers are pretty dire when it comes to network issues as there seems to be no sort of communication  channel between the customer service bods that deal with you and me and their network operations, when they do acknowledge an issue it can be a case of them having to negotiate access to their equipment etc.

This is one of the reasons I tend to buy low end to mid range phones sim free and keep it PAYG so if the service gets unusable I can get my PAC and move which is what led me here as 3 seems to be offering the best service around where I live (at the monent at least)
