Weird roaming messaged

[Peter274]

I keep getting texts from EE telling me that I am roaming in Jersey when I am at Nolton Haven in West Wales. The linear distance between these places is 350 miles, so can anyone explain how this happens? Has anyone else had a similar experience?

your phone wouldn’t register if the distance between phone and mast was over approx 35km, due to time-coding on the radio signal?

You're thinking of TDD & FDD, and the timeout. If the OP received the "welcome to country" text, that's a strong indication that registration has happened.

where the OP is points to a freak anomaly on the EE network most likely…

The anomaly would be that an EE-radio-site is configured to identify as a foreign operator.

Peter strangely for the first time I also today received that very same welcome to Jersey roaming message while on the beach at Mwnt, just north of Cardigan where I live. Almost immediately followed by welcome back to the UK. Must be a world record for travelling West wales to Jersey and back.

Pretty unique weather conditions that a Jersey network was stronger than an Irish or Manx one, I'm not sure what the roaming selection criteria are when multiple MCC's are available.
