One of the frustrating things about international roaming in the UK is typically your plan does not include coverage on this neutral network on the underground
I had a fun situation when I had friends visiting me in Japan for a road trip. One friend's US-model Android phone didn't support the specific low bands used for sparse coverage in rural Japan, but the repeaters inside of the tunnels were all on standard 2100 MHz, so whenever we drove through a tunnel he rushed to his phone to get some messages through. Kind of the opposite to what you usually experience with loss of signal in tunnels :)
Source? As someone that comes back to London every month, I’ve been able to roam the same as anywhere else in the UK. I’d be shocked if this were true.
Did the UK stop people from just picking up a cheap SIM at the Airport? I always like a local number when traveling. Anyway, Indian Roaming plans are so cheap these days that it's much easier and cheaper to just subscribe to them as part of the plan. These days, I don’t even need to add/activate it or anything, the providers turn it ON when I start my phone outside India and turn it off when I re-activate back in India.
The main problem if you're roaming is that you're considered a lower-priority customer, and since the network is often saturated already, you don't get any bandwidth.
