This is quite a technical query. A relative was in my house recently and noticed that his MVNO phone (on 1pmobile which is EE) got no signal while right next to a “real” EE phone. Swapped sims and the problem swapped.
What I later discovered was that EE do not allow their MVNOs full unrestricted access to their entire spectrum. I think in this case the 1pmobile didn’t get the 800Mhz signal which was part of 5G, and there must be an EE 5G transmitter nearby. Hence the EE sim got great signal, the 1pmobile got nada.
My question is - does iD get restricted the same way on the 3 network? If I get an iD mobile sim will it get exactly the same signal strength and network as a genuine 3 sim in all areas?
thanks
