Hello all, I need the help of someone with some technical network knowledge.
I have an iPhone 6s on the Sky mobile network, which uses O2’s infrastructure.
When I am out and about, I have good 4G coverage and the phone works fine. When I am at home I have 2 or 3 bars of 4G coverage but I cannot receive calls, though I am able to make outgoing calls, and send & receive SMS messages. People calling me hear an outgoing ring tone, but then instead of getting my answer machine, they are connected to a range of odd, recorded messages saying things like ‘The subscriber you dialled cannot answer the call for the moment, please try again later’. The messages are in English but with a range of different accents including Chinese, American and British English. I can replicate this by calling myself from my home phone.
As I understand it, when the phone detects an incoming call, it should drop to the 3G network to receive it, and this is the behaviour I see when I am not at home. When at home, the phone seems to take too long to drop to 3G, the call never comes through, and for some reason the mobile network routes the call to the recorded messages instead of my answerphone.
Sky insist there’s nothing wrong with their network or my local mast. They sent me a new SIM which exhibits the same behaviour.
Apple say there’s nothing wrong with the phone as I can’t replicate the behaviour at their store. (I have not got ‘do not disturb’ or other such setting active).
If I change the phone mobile data settings and force it to use 3G, then it works fine even when at home.
I previously used the same phone on the Vodafone network without any problems.
Can anyone offer any suggestions? Any advice greatly appreciated.
Thanks. Andy.
