Supporting a BG at the weekend, I noticed there was a huge variation between people who could get a mobile data signal and check the live trackers, and those who couldn't. My phone (PAYG O2) seemed particularly useless - I couldn't even load the tracker page in Keswick, let alone Threlkeld, or known problem spots like Wasdale & Honister!
A friend on EE seemed to have much more success, and another friend on Vodafone had a signal in Wasdale just a short distance back up the hill towards Scafell.
What about Honister? Where is the nearest place that actually gets a signal?
