HI, I'll be traveling to Taiwan and Japan for a month. I was wondering
1. If I just want to use my iPhone 6 plus like an iPod touch (I.e., using local wifi available to do email, using apps, etc, no calling nor text messaging), how can I set it up in my phone so that I can continue use it without causing any roaming charges? Do I just turning off everything in the roaming part and cellular data in the setting? I just want to be sure since I saw someone posted even they put it on airplane mode, it's still possible to cause charges.
2. I'm also considering purchasing a Taiwan SIM card to use in Taiwan, is that possible? And when I do that, I won't incur any verizon charges (except my usual monthly charges) while I'm using Taiwan SIM card, correct?
thank you for your help in advance!
