I have only "edge" signal almost all day now in london.

Is there a system problem or maybe my phone only?

Have you toggled flight mode, and - if that fails - restarted your phone?

[Hamyca]

Yes, I did of course. I have a double Sims phone. Other system (3) is working properly. Only the EE not.

Morning @Hamyca 

Thanks for coming to the community. 

Are you experiencing  Edge signal in multiple areas? 

If so, are you able to try the SIM in another phone to see if the same signal shows? 

Thanks 🙂

Leanne.
