Hi, I've flown to Poland yesterday and although my iPhone 4S has picked up the local T-Mobile signal, I am not connected to the Internet. I've had a similar problem last year when I went to Switzerland. I've got Clellular data on, Available 3G is on and data roaming on. The Web Chat told me the O2 p the APN to try is "mobile.o2.co.uk" This website uses cookies. By clicking Accept, you consent to the use of cookies. Hi, I’m currently in Germany and my data is not working even though it’s included in my contract. I’ve turned mobile data roaming on and changed the apn but it’s still doesn’t work. There is an E symbol on the top left of my screen when I turn the data on. I’m not sure how to fix this. Please help, If you have both an esim and a physical sim in your device, you will need to set one of them as your default data line in your device settings. You will only be able to receive one call at a time; during a call, any incoming calls to the other number will be diverted to voicemail. If you are using an O2 esim in a device from O2 and your device Y0pcV.
