Instructions: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Input: Simply useless if you are not in a mayor city with 4G. Even outside of the LA area it started to disconnect. The subscription is very expensive 34.99 or more. It took me several tries to cancel my subscription, I had to call the credit card company to invalidate the charges after several expensive international calls. Their 800 numbers not valid outside the US
Output:
Will not work in areas without 4G, It will not work in Mexico either as advertised.
