Yes, please remember your data allowances are only available within in the UK. When using the GPS/Maps function while abroad you will be charged for accessing data. Your iPhone will connect to the internet in order to access maps, as there’re not stored locally.

For example if using Maps/GPS function on ‘Satellite’ view, travelling for 10 miles whilst viewing this, will equate to about 1MB of data. This can be reduced when using ‘Map’ view.

Data within the EU is charged at £3.07 per MB, data outside the EU is charged at £6.00 per MB.

In most countries Visual Voicemail will work as it does in the UK. Where it doesn't work you can access your voicemail from another device by dialling your mobile number, pressing * during your greeting and following the prompts.

 

If Data Roaming (in Settings > General > Network) is switched off on your iPhone, Visual Voicemail won't work at all. Instead, to get your voicemail overseas, you can:

1. Call 901 (there might be a charge)

2. Switch on Data Roaming (in Settings > General > Network) while you look at Visual Voicemail, then turn it off again. We don't recommend this, though, because some of your iPhone apps might automatically send or receive data and you'll be charged. It's £3 a MB in the EU and £6 a MB everywhere else, so it's a bit risky if you don't want an unexpected big bill when you get back.

Some of our tariffs come with International Traveller Service(ITS) which means you will enjoy discounted rates compared to our standard prices, when you make and receive calls abroad. To check if your tariff has ITS log in to your account online at MyO2 and you will be able to see what services are included within your tariff within the My Bolt On’s Summary section Further information on International Traveller Services is available here: International Call Service Your inclusive data and Wi-Fi allowances only apply to usage in the UK. Downloading 1MB of data in an EU country will cost £3.07 and the same amount of data in a non EU country will cost £6. We will stop charging you for data abroad when your data usage reaches £40 (inc VAT) within any one billing period. You can then continue to use data until you’ve reached 50MB without any additional charges.

We'll also send you alerts when you've spent £20 and £40 on data, when you're nearing the 50MB limit and if you reach it. If you do reach 50MB your data service will automatically stop working, so if you want to use more you'll need to opt in to a higher spending cap (ideally before you go) by calling Customer Services.

To use your data on your iPhone abroad you will need to ensure that you have data roaming switched on, to do this you need to follow the below steps:

• Settings
• General
• Network
• Slide the Data Roaming switch across to yes

If you're abroad Wi-Fi will be subject to local charges.

Please note some of the unique features of this iPhone automatically use data services. You may wish to turn off some of these services before you travel e.g. automatic email updates if you do not wish to be charged. You can do this by selecting - Settings – General – Network – Data Roaming – switch button to 'Off'.

For further information about using your iPhone abroad, please go to www.o2.co.uk/international

If you are abroad when the call is diverted to Voicemail on no answer or busy, the caller is charged for a UK deposit call and you will be charged for a UK to roaming call and a roaming call to voicemail (this is as per 901). If the call is diverted to voicemail on unreachable, the caller is charged for a UK deposit call and you are not charged.

Note: If you do not wish to receive these charges we recommend that the Voicemail divert is disabled before leaving the UK.
To switch Voicemail divert off dial 1760. To then switch it back on when you are back in the UK dial 1750.

Simple, just tap "Settings" on your iPhone, select "General" then "Network" and simply slide "Data Roaming" to off.
