Important Information

- If customers use their mobile in the Europe Zone for more than 50% of the time in any 3-month rolling period, they will receive a notification requesting more moderate use of our roaming services
- If customers usage in the Europe Zone continues to exceed 50% as described above, over the 2-week period following the first notification, customers will either be charged for use or be barred from using our roaming service
- For unlimited tariffs with a monthly data allowance greater than 35GB, Global Roamer data usage is capped at 35GB per month. Data usage above the 35GB threshold is chargeable at £3.50 Ex VAT per 1GB until their monthly allowance renews
General

Inclusive EU Data Roaming of 35GB per month. Overage will be charged at 9.0p/MB. N.B. Unlimited Plan – A fair usage policy of 650GB domestic usage per month will apply.
If bundles are changed mid month then the allowance will pro-rate, for example if a customer is on a 20GB plan and upgrades to a 50GB plan on the 15th of the month the allowance calculates as follows. 20GB divided by 30 days (full month) multiplied by 15 (days the customer had the bundle) to give 10GB for the first 15 days. Then 50GB divided by 30 days (full month) multiplied by 15 (days the customer has left in the month for the upgrade) to give 25GB for the last 15 days, 35GB in total.
Fair Usage Policy
Unlimited Data – UK usage
- If a number regularly uses 650GB of data per month or tethers 12 or more devices, we may consider this to be non-permitted use and have the right to move the number to a more suitable plan and/or charge for the excess data usage
- UK to EU Minutes and text policy of 2000 mins and 2000 texts and then standard charges apply.
- For plans with Unlimited data, EU Data Roaming will be capped at 35GB per month. Once customers reach this, they can still use data in our Europe Zone and will be chargedat £3.50 Ex VAT per 1GB until their monthly allowance renews

Mobile Misuse
O2 reserves the right to suspend or terminate connections where it identifies usage which it believes is:
- Outside normal commercial practice.
- Made via automated means e.g. SIM Gateway.
- Damages or impairs our network.
- Fraudulent, abusive, illegal or a nuisance.
All of these activities would fall outside of the Fair Usage policy, and such will not be supported by the Mobile Bill Limit Regulation (mobile spend cap). Please contact our team for further detail.
