I've just returned from Italy where I was unable to access any data while roaming. I was able to make and receive calls and texts. My problem now is that I've no service at all (data, calls or texts) now that I'm back in Ireland.
When I turn-off auto-select of a network, my phone now shows "48 4G" as an available network (among all the usual ones (Vodafone, Meteor, etc) but if I select it, I get "the network service you selected is unavailable. we recommend turning on Auto Select". If I turn on auto-select, I get "cannot connect to this service at the moment - try again later".
My phone is a OnePlus 9. I've been on My48 for several months and the service was working fine until I left the country last week. My home page shows that i should have unlimited calls and texts. I tried the 48 SIM in my old OnePlus 5 and the same problem shows up.
I'll log a call with support in the morning - just wondering if anyone has seen a similar problem.
