All UN, PN and LN units (North American Units) will only have support for ATSC/QAM broadcasting systems and NA power systems. Since the NA TVs will not accept a PAL signal or Non-NA voltages, you will not only need a converter for the broadcast, but also for the power if you would like to use the TV in a PAL country or in a different power environment. Unfortunately, I will not be able to recommend a specific converter since Samsung cannot offer support for products we do not manufacture.

That said, I cannot provide any information on the UA55EH6000 since it is an international version and I cannot speak for international versions of Samsung products.

Thanks for being a loyal Samsung customer, and we sure do appreciate your continued support (and consideration!) of Samsung products.

You do have Allshare Play option, which allows you to play music saved on your devices, like your PC, Smartphone or NAS through the Wireless Audio with Dock and the a network connection.

You also have Dual Docking, which allws you to have a docking station to dock, charge, and play either Samsung Galaxy devices or select Apple devices through the system's built-in speakers.

Further, as more devices become Bluetooth enabled, this dock is ready for wireless connection to your other devices today, and that makes future use and future options wider and more robust, giving you the freedom to choose devices that use the popular Bluetooth standard.

On that note, it also has aptX, and aptX enables high quality Bluetooth stereo audio, delivering wired audio quality wirelessly.

Thanks for the question, and if you have any more inquiries, ask and we'll be happy to help answer them!

Although I cannot speak for carrier plans or policies, usually a SIM card can be purchased directly from your carrier or from Best Buy Mobile.

As a matter of fact, the UN32EH5300 should have access to the MLB.tv App within the Samsung Apps ecosystem.
