Wouldn't advise it. The ones that look like good deals are next to useless and the ones that do work are expensive. On top of that, depends where you are staying with respect to civilisation. Poor Internet in hotels is normally due to poor infrastructure in the surrounding area. You can therefore bet that mobile data coverage isn't going to be that much better. Instead choose hotels that embrace the 21st century and that realise you cannot service 200+ rooms with a single 1Mb connection!
