I'm not sure if it's been brought up much here but there is a cell phone
plane through Google
Fi. It's a world phone
that uses both types of towers cdma and gsm (or whatever they are called). Pretty basic billing and no crazy fees
. It's $20 a month for unlimited calls, texts, and voicemail. Then $10 per GB you use. If you only use 2.5 Gb then the extra .5 is forwarded to next month so you get to use everything you pay for. It also connects to Google Wifi
spots around the world. No roaming charges. Get on a plane in the US fly to Italy
turn it on and use it with no worries about any extra costs.
Me and my wife just switched from Verizon. Here in the states they use Sprint, T-mobile, At&t, and US cellular towers. We are saving about $60-80 a month over Verizon. The biggest downside is you have to use one of a few phones that are dual band like the new Pixels, the Nexus 6P, or 5X.
I just thought this might be helpful especially cruising the Caribbean
or I guess anywhere really. Check out their site for more details or chime in if you're already using it abroad. I'm not affiliated just a very happy customer! Great an easy customer service
too, just hit a button for help and someone picks up the phone!
