O2 Network Coverage very poor in North Prestwood

by Mark Wingrove

Around the beginning of December my mobile phone started to drop calls while in the house. I did not think much about it at the time, but it has become a bigger problem since that time, with complete loss of coverage sometimes and missed phone calls. Prior to the beginning of December 2021 I have always had great coverage at home for my mobile phone, it has never been a problem.

What happened

During December I checked my mobile service provider’s website for any issues. I am with GiffGaff who use O2’s network. A message popped up to say that there was some maintenance activity going on at a mast near my location and it would be fixed by January the 7th 2022. It was not fixed, the problems have persisted right up until now (Feb 2022).

I know that it is not just my phone because 4 other mobiles are affected in the house. That is indicative that the cellular coverage for my location has changed. I have not built a Faraday cage around my house, or had any other building work done, so it looks like a transmitter/ receiver problem in the cell I am in. While seeking support from GiffGaff I have been asked if my building has changed. 

Ground Hog Day

I seem to be stuck in the movie Ground Hog Day right now. It works like this: You complain to your provider (GiffGaff) they tell you to turn your phone on and off. So you go through all of the standard 1st level fault finding, nothing changes and they say we will flag this as a fault. They flag it on their coverage map to indicate that a fault has been reported in the area. You check 2 days later and they tell you no fault found. So you raise another ticket and we start again. I am on my 4th trip around this cycle now, it has even been flagged by GiffGaff to O2 and O2 reported on their coverage that a problem has been reported, and now it says it is all working. I was due to get a call from an O2 Guru and it never happened. So I am back at square one again.

How do we break the circle?

Over last weekend I placed a comment on the Facebook pages for Prestwood Village Association and Your Prestwood and Great Missenden. It appears I am not the only one, and several other people in the north side of Prestwood (Honor End Lane/ Kiln Road) are also affected. It also appears a few people have complained as well, and as with me, nothing has happened.

Nanfans Farm Antenna

Malcolm Appleby on Facebook pointed out that the coverage map for Prestwood no longer shows the antenna at Nanfans Farm on the maps. However the coverage for the north of Prestwood is still showing as 4 bars and 4G. It used to be, but outside I now get 1/2 bars and 4G and inside often nothing. Here is the print out for the status on the 5th of February for HP16 9HQ (Honor End Lane). The report suggests that I should have full coverage inside and out. 

Network Coverage map for Prestwood (North)

Below is a screen shot of the coverage map for Prestwood from The Chequers out towards the Sprinters Sports Centre on Honor End Lane. It shows good coverage and strong signals both inside and outside for all of Prestwood. The 1 marked on the map is the post code HP169HQ.

This map shows the mast serving Prestwood is located along Wycombe Road. (Pale blue balloon shaped marker). If you walk in that area the cellular coverage is quite good, particularly where the common is, to the south and the west towards the mast, but further north it weakens. Along Honor End Lane, and Kiln Road is now quite poor and not representative of this coverage map. Blue shading indicates Good Coverage indoors and out and good for mobile broadband with 4G selected.

What may have happened?

There is or was a cellular site at Nanfans Farm. The aerial is still there, and it is still transmitting but at low power. The O2/ GiffGaff signal gets stronger the nearer you are to the aerial, but power overall is very low. As pointed out by Malcolm Appleby on Facebook the site no longer appears on coverage maps as can be seen above.

If this is the case, then it is quite conceivable that O2 checks their cellular sites and confirms they are all working. Because they are not looking at the one at Nanfans because it is no longer on their map. That may account for why a fault gets raised and then nothing happens.

Are you affected?

This is highly speculative, but if you are on EE, Plusnet Mobile, O2 or GiffGaff, and you live in the yellow shaded area, then your coverage may have dropped from December. I know EE is the same because I thought I would get around the problem by switching to Plusnet Mobile, but it is exactly the same. 

The map below is interactive, you can see the allegedly decommissioned tower on the map inside the yellow area. The other mast; the only mast serving Prestwood seems to be located behind the Wren Davis Farm in the fields roughly adjacent to Lodge Lane entrance on the Wycombe Road. 

Possibly decommissioned mast at Nanfans Farm on Honor End Lane

The mast is still there, and there is some signal present at this location the closer you get to it, but the power is very low now. It is quite likely that this mast has been removed from the cellular network, that may be the reason why the service is now very poor. 

What can we do about this?

I, along with several other people seem to be getting stone walled by the big service providers. This is not a complex problem to resolve. Either the mast is decommissioned, in which case we would like it recommissioned because the cellular coverage map is no longer valid for our area, or it is faulty. I suppose one solution might be to increase the power from the one on Wycombe Road. But the bottom line is our service has been withdrawn. I did not see any notices about it, and I doubt you did either. I am still paying for it.  With many of us still working from home it is of greater inconvenience because many of us rely on the cellular network for work and staying in touch with colleagues. It also means if you back up your broadband data with cellular broadband, that will not work now for many people.

If you have been affected since December 2021, please add a comment below. I would like to point GiffGaff to this article and O2. If that does not work I will escalate it to the Ofcom Ombudsman for O2 and GiffGaff. If it is a lot of voices complaining it is more likely to get a result than just one or two. If you would like me to include you in any further communications please send a message to prestwoodmobilephone@wingrove-media.com 

Thank you

Mark. 

Update: 10/02/2022

Firstly thank you to everyone that has responded to this. I am relieved that it was not just me, but it is frustrating to see so many people complaining and yet not much seems to be happening. One thing has changed, which is a message on the O2 coverage site for our area, where faults are reported. The message, is the wrong message;  it is not because of over subscription (we would all have 4 bars of signal if it was over subscription), but it is a step in the right direction. Clearly someone is looking. O2 have agreed to send an engineer out on Monday of this week (info from Chris Huxtable, well done Chris).

What next?

The pattern so far has been typical of large organisations with incumbent customers who are already locked in, an individual denial that there is a problem is difficult to argue with and progress through the layers of support. With currently 21 people commenting on this thread, it is more difficult to deny.

If you are an O2 client and are affected by a poor signal, please complain directly over the phone to them and point them to this address: https://prestwoodva.org.uk/giffgaff/ and then they can see for themselves. Please keep the pressure up and we will get this sorted out, or escalated to Ofcom.

Thank you for supporting this initiative.
