Some streaming platforms allow you to register from anywhere. but prevent you from actually viewing any content if you're outside the broadcast area. Others limit their content libraries based on where you are. Using a VPN can solve these problems.
But, some services use more lock-in measures to prevent foreign users from signing up. For example, you might be asked for a local address or phone number. You may find that the payment method needs to be registered in the specified country/territory. These services are inaccessible to foreigners without local friends or relatives willing to help.
