We respect Frommer's but honestly wonder why they put subpar recommendations in their book, that in the end must have cost their readers a lot of money over the years. Just look at the link below and compare rates and service with the other company they recommend.
Their on line Frommer's Costa Rica website is still not current with Costa Rica Cellular Connection, but this is a start. We offer the best service in Costa Rica and plan on continuing to do this in the future, just as Frommer's offers the best in travel guides(Besides their slowness on getting their facts straight on mobile phone rentals for Costa Rica :)
Get your cell phone rental reservation in now, before we run out! Pura Vida. Thanks for stopping by.
