There doesn’t appear to any service whatsoever, on any network. The Ofcom checker states the same.
Although we’ll have Wi-Fi, some level of mobile service is required for 2FA for logging into some work things. These are text, not data, messages.
I read that O2’s boost box “works by connecting to a router and sending traffic over the broadband network to increase mobile signal.” But if there is no signal there to start with, will it do anything?!
Anyone have any experience of this and found a way to receive text messages at least?
