Wi-Fi during the cruise

The bandwidth for the Wi-Fi onboard Celebrity Equinox was not sufficient for voice or Facetime/Skype. It was acceptable for text and email.  The good news is that the Wi-Fi connection inside the cabin worked fine. 
In order to stay connected with family back in Denmark we did find cafe's when ashore where we for a purchase of coffee could get free Wi-Fi . Mostly acceptable for Facetime.

Cozumel, Mexico: Cafe Punta del Cielo just outside the terminal that had a hour free internet with $5 purchase of coffee/drinks.
Puorto Limon, Costa Rica: Just outside the terminal next to Parque Vargas we found Cruccero Coffee Shop with a good wi-fi for Facetime/Skype. Free wi-fi when buying drink/coffee.
Colon, Panama: At harbour/cruise terminal several Cafe's with free wi-fi when purchase coffee or dring. Fair connectivity.
Cartagena, Colombia: In the Souvenir shop at the cruise terminal with wi-fi area. $3 for an hour - fair to bad connectivity. Must find the right spot within the wi-fi area.
George Town, Grand Cayman: Southwest Collection Cafe located at first floor in Harbour Place in South Church Street. Free wi-fi when purchasing coffee - good connectivity.
