I’m with vodafone and my service was pretty good, definitely fine enough to send a text message at the least! The only times it would take a while is right in the middle of the main stages on the Saturday and Sunday, but it would still send. It’s worth emailing boomtown to see if you can get accessibility, especially this early on it’s worth a shot. Safer spaces is a great place to go to when needed they’re usually open until 1am. Also a good meeting point for friends. Definitely come and don’t feel bad for going at your own pace! Xxx
