Yes and no. Your camera works coverage or not. The internet service is spotty and slow depending on where you are in the Whites. It is all line of site with the closest tower in Twin Mountain (west), Gorham (north) and Conway (southish). So if you are in the Ravines, service is bad but if on a ridge with line of site, it works decent. But, it should be said that your provider is a bigger issue. If you are Verizon, can be a bit difficult to get a steady, useable signal but ATT is the better of the two major carriers. But with dopplar, be prepared to just get still images as trying to get a loop takes way too long and drains your battery (talking from experience). So, carrying it as a tool is ok.
