You can get a prepaid hotspot plan with 5GB for $50 for 30 days, you will need to buy a Mi-Fi device, such as the AT&t Unite. Here are the plans: GoPhone Mobile Hotspot
You can activate your iPhone too and have calling and texting locally or internationally (for additional charge), and use data on the phone, but not share it with other devices.
Where are you staying? Wi-Fi Hotspots are very common here and most hotels and restaurants / coffee shops have them for free.
Thanks,
