Welcome to the iD Community.
In relation to tethering, you can find the answer here
Tethering price information
Please note that we
do notallow tethering on any of our current plans. If you do use this service it is likely to use up large amounts of your data allowance very quickly, and you will be liable to pay any charge that may occur if you go over your allowance. Please check for updates on our website as this may change in the future.
If you get this to work, you would be using it at your own responsibility.
Since we do not support this, we're not able to provide Technical Support on this.
Let me know if you still have any questions.
