Suddenly I can’t dial UK landlines while in USA

[poc]

I’m roaming in the USA. Last week I could call the UK from my UK mobile but this week the calls fail. I have Bolt on and roaming all included with unlimited calls but nope, calls just drop now - what changed.

have I inadvertently changed a setting, has my Bolt on changed. WiFi calling is off as it should be according to O2.

 Of course no technical help from O2 🥹

Have you moved to a different city or state? Manually search for a mobile network, @poc - you can use any network, even if it shows as Forbidden in the list of networks, when roaming. Also there are limits on how long you can roam, 63 days at a time, from memory - in case you're on a long break there. Good luck!
