if you are going to buy an IPTV Package, you should be aware about the type of your product. if you have a single device for IPTV, then its OK, you can buy a normal IPTV Package and connect it to your device. Usually IPTV Accounts have a 1 device limit, that means Only 1 device can be using the service simultaneously. So, If you need to connect more devices, you have to purchase another account with the same time period. For example, if you have purchased a 6 months account ($45), you have to pay for another 6 months account in order to have 2 simultaneous connections for the same account ($90 total).
But, there is another option. You can buy multiroom service (at lower price), that provides IPTV service with limit of 2 device simultaneously. it means that you can have two devices working with same account. just buy a multiroom service, and connect it to your devices.
