The Slingbox M1 is only supported in the United States. You can still use it outside of the two country's listed but if anything happens, there is nothing that Sling Media can do for you due to the box is only supported in the United States and Canada.
Hope this helps!!

Thanks for your reply, I followed your instruction and was able to watch my tv using slingbox m1. My problem now is, I can't find the appropriate cable box manufacturer among the list provided by Slingbox. I have a Hathway Skyworth S7681 Digital TV box. My TV provider is a Cignal Philippines.
So I can't change channel remotely.
I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/message/10363#10363
Come back if it that doesn't help either.
