Unlimited UK data is intended for use only in mobile devices that operate independently and do not require constant connection to mains electricity. If a user regularly tethers to 12 or more devices or exceeds 650GB of data in a month on two occasions within a six-month period, we may review the usage to determine if it aligns with average use.
If we reasonably believe the data is being used for non-standard purposes, we reserve the right to take appropriate action. This may include changing your plan (including what’s covered in your monthly charge and the rates for out-of-bundle usage), reducing data speeds, or terminating your agreement.
In addition, when roaming outside the UK in standard inclusive or daily roaming destinations, unlimited data plans are subject to a fair usage limit of 25GB per month. If you exceed this limit, roaming restrictions and/or out-of-bundle charges may apply
