I am a bit confused. I want international access for two iPhones for about a month in Europe. I expect to use email, phone, and data. My understanding is that with a TravelPass I use the current data allowance on my plan, and there is a $10 fee each day I use the phone. If I used one phone 20 times, or each phone 10 times, that would be $200! My understanding is that with an International Travel 100 plan I pay a flat fee of $40 per phone per month, and get 100 calls and 100 MB of data per phone. $80 for two phones for the month seems a lot better than $10/day each.
However, when I examining the sign up for the International Travel 100 plan, it had an option of ADDING the TravelPass. I do not understand how these two programs would work together. Do you pay a flat fee of $40, but it uses your plan data? Do you pay $10/day in addition to the flat $40/month (and why would you want that)? Thanks for any info.
