It should be remembered that mobile microwave towers operate significantly line-of-sight. That means that users in ED - which is full of annoying hills, frequently are in microwave shadow. This will lose or attenuate signals. [signals will go through most buildings OK, but have a problem going through the ground, which hills are]. Additionally towers are limited in the number of simultaneous transmissions they can handle, giving priority to ongoing transmissions. So if you are in a location served by a tower with a lot of existing traffic being handled you will have a problem obtaining signal, even if otherwise you are in a good position to do so. If you are near busy roads (ie the EDT) you will find people passing (walking by and in cars) who are already interacting with the towers, so you will be competing more for signal. You may also find (for data) that you have grabbed WiFi access in some places (depending on your supplier and what deals they have done) and not others. By the way, the numbers of 'bars' shown is very unhelpful in judging signal strength - other than a 'no bars' condition.


For ED different service levels frequently reside in which network you are using and where their towers are. So if you are, at home, well situated for one service you will find that 'better' and be surprised that others (served by different towers) don't agree with you.


I live just under the brow of a hill and visitors on some networks can have problems getting service downstairs, but no problems on upper floors. Annoying, but physics.

Their are a lot more mobile cell sites than people realise - https://www.mastdata.com/37/37_map_mobile_mast.aspx?Table=15&AdTyID=43&ROName=SE22&Z=14


T-Mobile = EE.

I happen to know the cell site for EE on top of the Coop is being significantly upgraded.


Most operators have two frequencies 900Mhz and 1800Mhz. They started 4G rollout with one frequency and are now adding the other which has much better building penetration. So all operators are improving their networks but it does take time.

EE sent me a small femtocell for free because they recognise that the signal is poor in the East Dulwich area. This was about a year ago.

A femtocell (signal box) is a small box you connect to your router with a LAN cable so that it sends a 3G wireless signal. Vodafone used to charge for this (no idea what they do now). EE doesn't charge if they recognise the signal is poor. This thingy has improved the signal, but it's still not perfect, i.e. sometime I still get issues even when calling landlines.

On 4G? 3G/HSPA cuts out in a triangle from Belvoir Road to Melford Road with EE I've found where the signal from the cell site on the corner of Dulwich Common/LL (the big black pole that looks like a street light) doesn't reach.

I am with EE and am having problems. Just spoken to them again re drop out and was told they have 11 frequency settings they can try. Never get a straight answer from the different operators but have insisted that it is all detailed on computer so I don't have to go through the whole thing again. Yesterday operator said was to do with BT line that they share...!! Thanks for mention of femtocell might ask for one of those next call or maybe even a booster. Not sure if I left them, the service would be any better so will continue for a bit.

If you are having problems with any mobile operator after repeated attempts at contacting them then email the Chief Executive:


EE - marc.allera@ee.co.uk

O2 - mark.evans@telefonica.com

Three - david.dyson@three.co.uk

Vodafone - nick.jeffery@vodafone.com


None of them want unhappy customers. They will all have teams for complaints they receive.

You could also look into wifi calling. It means that the phone gets the signal from a wifi conenction; it's all seamless, you don't need to do anything other than enabling it once.

It typically works with most phones supplied by the network operator directly, and with some phones bought unlocked elsewhere. The EE and Vodafone websites have all the details. I have both the femtocell and wifi calling on EE; they're OK, but they're not perfect, and call quality can be a bit hit or miss at times.

James, and others. Many people take service not directly from the carriers but from Mobile Virtual Network Operators (MVNOs) such as Virgin, or TalkTalk etc, who lease capacity on a wholesale basis, from the network carriers you have listed. As such their contractual relationships are with their Operator and not the underlying carrier. It is their operator who has the relationship with the carrier. This makes determining who is 'at fault' more problematical, and CEO's may be less stimulated to meet the needs of someone who is not, directly, their customer.


On the other hand, complaints from an MVNO, who will have a significant financial relationship with the network carrier, may carry more weight. Ideally get your MVNO batting on your behalf with the underlying carrier. Which may mean writing to your MVNO CEO!

Hi P68,

Yes, but I couldn't list all the MVNO's. Between the main 4 operators they have over 85% of mobile customers.

But easy to Google for the CEO email address of any other operator.


For most problems just a mater of an operator adding a frequency better at penetrating building. They pretty much all have plans for this or adding transmission capacity. I happen to know for example that the EE site on top of the Coop on Lordship Lane recently took delivery of a new 1GigE pipe to replace 100Mbps pipe.

    • Yawn.. as I and others suspected the noticeboard is already looking shabby, has the details of local councillors who in my experience are of very limited help with anything at all (e.g. noticeboard took several years of writing to get back in working order and now isn't being kept up to date with any useful local info about food banks or any services as promised). So nothing at all in left hand side. Pointless and a real shame as could benefit so many small businesses.. and no I don't own a small business I just believe in supporting shopping locally where possible and know they often have little to no marketing budget.
