We're trying to figure out which electronic devices to take on our summer trip to Japan, and how we'll use them. We'd like access to the internet while we're out and about (google maps and such). Being able to make local calls or send texts would be nice (what do most tourists do?).
1) Hub has a locked smart phone. If we get a data SIM card for that, can he use it for anything (texts or internet)? Or if we have pocket wifi, can he use it just for internet?
2) ipad - If we got a pocket wi-fi, we can use this for internet anywhere, right?
3) We also have an unlocked smart phone that we take on international trips, and usually get a local SIM card. We've only used it for local calls abroad, so not really familiar with apps that might be helpful. Should we take this instead of the unlocked phone? Then data SIM or pocket wifi, or both?
Thanks for your help!
