2. 如果需要分开买， 西葡边境哪里可以买电话卡?怕一进葡萄牙就迷路了，如果没有GPS, 怕都不知道怎么开到里斯本了
Use offline map. Download Navmii Spain and Portugal. In my case, purchase a separate plug in microchip with whole europe map
3. 怎么取现金?是在银行还是ATM上?用信用卡还是debit 卡?
Can use Charles Schwab card. Deposit USD, and withdraw Euro.
4. 汽车加油是不是美国信用卡都可以用?是到里面付款吗?
Same as above or any american credit card without foreign transaction fee, like Capital One, Discover, Many Chase credit card; Yes, pay inside.
5. 西葡两国的tollway 都是怎么付款的?有booth 可以人工交费吗?
Some can use booth, some unmanned booth, you can insert euro; Some toll road don't have either. You will have to wait for the bill when you get home.
