No, coverage is no problem with all the three major net providers: Movistar, Orange and Vodafone. But you should prefer a 4G-SIM rather than a 3G for data. There is generally good 4G in towns, falling back to 3G in some villages and sometimes only 2G in very remote areas.

Which one of the three is better, depends on your location. Orange's resellers are the cheapest at the moment.
