1. Why Use Only WiFi on Your iPhone While Traveling?

Traveling with your iPhone can be a fantastic experience, allowing you to capture memories, navigate new cities, and stay connected with friends and family. However, using cellular data abroad can lead to significant roaming charges. According to a 2023 report by the Vietnam National Administration of Tourism, international tourists often cite unexpected mobile data costs as a major travel concern. By using WiFi exclusively, you can avoid these charges and enjoy your trip without worrying about surprise bills.

• Stay Connected: Access essential services like maps, email, and messaging apps without incurring extra costs.

2. Understanding iPhone’s Data Settings

Before diving into the steps, it’s essential to understand your iPhone’s data settings. Here are the key settings you need to know:

• Cellular Data: This setting controls whether your iPhone uses cellular data for internet access.
• Data Roaming: This setting allows your iPhone to use cellular data on foreign networks. It’s crucial to keep this off when traveling internationally.
• WiFi: This setting enables your iPhone to connect to available WiFi networks.
