I recently signed up for a telecom package in Guangdong, China that includes three phone cards and 500M of broadband service. However, I didn't realize at the time that this package did not come with IPTV. Now that I'm aware of this, I'm wondering if I can upgrade my current package to include IPTV without incurring any additional costs. I would appreciate any guidance or advice on how to go about doing this and if there are any specific requirements or qualifications I would need to meet to be eligible for this upgrade.
