Hey there, hope you can help as O2 and Samsung are unable too. I travel abroad (EU) quite often with work and after being with Vodafone for like forever, when they eventually stopped their inclusive roaming I was stumped. However, I saw O2s TV advert that they were still doing it and so I switched to them, PAYG, as I was with Vodafone.. My number was ported and all good. My first trip abroad, Spain and Gibraltar, and I couldn't receive calls. My phone would simply alert me, with an SMS, that I had missed a call. After this happened a few times, I got a colleague, who was literally sat next to me, to call, and put it on loudspeaker and the call doesn't even connect, just goes straight to my voicemail. I can call out OK, so it's not a "signal" issue, and this happens in multiple locations too.
Also, whilst I receive SMS OK I cannot send SMS. O2 and Samsung have tried everything, no joy. My phone was originally quite dated, an S8+ but I have since purchased the newer S20+ in the UK, only a few days before my next trip abroad however, arrived in Spain and again, same issue.
I am also aware of the fair usage policy but literally have had hardly any usage and so not related to the none access, and wouldn't make sense that I can still browse the internet fine and make outbound calls.
Thanks
