Last year I had a problem when traveling to the US with my Pixel 3a: I didn't have any network (no data, no call, nothing). Upon contacting O2 they said they needed to enable Wifi and 4G calling, but even after that, it never worked, even though my p...

I'm currently traveling in the US and just bought myself an iPhone 15 Pro. To my surprise, the US version doesn't have a Sim card slot, it only accepts eSim. I urgently need to know if O2 can provide me with an eSim for my phone number, and if so, wh...

I'm traveling in Rhodes, Greece. While I'm supposed to be able to roam free in Europe, I just realized that my phone has connected to Turkish operators from time to time and I have been charged for it. I have O2 Travel bolt on, so I see a 5€ extra ch...

Its' not finding any and gets back to automatic network selection, unfortunately.

Thanks for the explanation, @MI5 . O2 answered on Facebook and activated Wifi and 4G calling on my account. It's been nearly 24 hours now and I still don't have any network. I can confirm that on the O2 app, in Device details, 4G Calling is shown as ...

Is this 4G Calling requirement a recent change? I had no problem roaming in the US with this phone and tariff back in February, and in the past as well (I traveled to the US frequently until the pandemic hit, with this phone and a tariff with O2 Trav...
