When on a recent trip to Cuba, I had phone data turned off and as well airplane mode, however, I noticed that my airplane mode what shut off for possibly for 2 days so am I going to have roaming charges? I checked my usage and do not see any charge there
To begin with if you don't have international data roaming add-on turned on, you won't be able to use any data. If you look and have it enabled in add-ons. Plus if your data was off, you're good on top of that. Great thing about multiple redundancies :) you should be fine.
