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...

I have a Pixel 3a, with a 150GB tariff which includes O2 Travel Inclusive Zone. I was able to use 4G in the US back in February with this phone and tariff. I'm back in the US today and I don't have any network whatsoever (I'm at the same place as las...

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...
