If you cannot connect to data while roaming:

1. Check data settings to ensure your mobile data roaming is enabled.
2. If you are roaming outside of the EU, make sure you have accepted all relevant T&C’s when prompted.

In the EU you will be charged for roaming if you exceed your allocated allowance of 16GB.

Data allowances if available at the time of roaming can be used while roaming in the EEA subject to fair use limits where applicable. EU roaming fair use allowance is calculated in line with Regulation (EU) No 531/2012 (as amended) and Data wholesale roaming price caps. Where the domestic data allowance has not been fully consumed but the fair use allowance has been fully consumed, a surcharge rate of €1.91 per GB/€0.0019 per MB (based on Regulated rate of €1.55 per GB excl. VAT) will apply until the domestic allowance has been fully consumed. Standard domestic rates apply thereafter.

You can use your calls, 10,000 texts and up to 16GB of roaming data anywhere in the EU while roaming.

If you are roaming within the EU, you will not pay to receive a call.

If you are roaming outside of the EU, you will pay for receiving calls.
