*You will be charged for incoming calls if you're using your Equipment abroad outside of our Europe Zone (including the cost of receiving voicemail messages). If you use Services abroad outside of our Europe Zone, it will usually take longer to be billed. It's best to check the cost of using your Equipment abroad outside of our Europe Zone before you travel. Accidental roaming might occur if you are in an area close to national borders because your Equipment picks up a network across the border. If this happens, you may be charged as though you were roaming on an international network. You can prevent this if you are near a national border by setting your Mobile Phone or other Equipment (as applicable) to do a manual network selection and select the 'O2' Network.
