may be in pr are other cariers unlimited like t mobile but their signal is really bad there are a lot of places that they fail sprint to me has been one of the best carriers in the island i have been with all of them and all has their problems claro voice service stinks there are doop calls everywere att is to expensive and customer service stinks and open mobile isin't that great . sprint will be the first to have lte in all the island not only in the biggest cities. if sprint dosen't satisfy you go to another company an good luck
