Manual network selection - dual EE signal listed

Just wondering what this other EE signal might be? The sim is a EE payg, if i put another EE payg sim into the same pixel device, again the handset shows the additional EE signal, as forbidden.

The pixel device's network settings have been reset a few times too.

It doesn't have any impact on the call/sms/mobile data experience, just curious!

EE forbidden

The image hasn't been approved however is the forbidden network 5G by any chance?

In response to the precious post, all radio access technologies use the same MCC/MNC

EE's network code is 234-30, but all radio sites are configured with the commercial network code and also the MCC for ESN which has its own core network and thus difference network code.

It's that which is shown here.

@bristolian - so you are saying that the additional EE signal is for emergency services?

Yes it would be, on my device it shows up separately as 23432 but I believe certain phones may convert this to a network name based on the code.

You can read more about the ESN here: https://business.ee.co.uk/large-business/esn/

This isn't really additional signal.

Telecoms networks - put very simply - operate in two parts. The "access network" allows your device to access the network, which will either be the physical cable to your premise (for landlines) or the radio site (for a mobile network)

The core network provides the centralised functions such as subscriber management and call routing.

Thus under ESN, blue-light users use the same access network as commercial customers but their SIM are provisioned onto a separate core network, and their traffic is routed via that core rather than the commercial one that you & I use.

The "alternate" EE you see on that network search is the ESN-core. Using the same radio network as you are.
