Three недавно отменили fair usage policy.
Возможно, но Terms And Conditions на сайте всё ещё говорят об ограничениях.
"The Service is available for use with your SIM Card in your handset only. Tethering or use of your handset as, or the SIM in conjunction with, a modem is not allowed, except in the case of Three customers who have subscribed to a Three handset and Tablet bundle offering. In the event that we identify that you have breached this condition, Three reserves the right to suspend, modify or restrict your use of the Service or to withdraw your access to the Service at its absolute discretion."
