How to Stay Connected Abroad: Your Guide to Hassle-Free Internet While Traveling

In today’s hyper-connected world, traveling without internet is like setting off without a map. Whether you're using Google Maps to find your way, translating menus with an app, or uploading stunning travel photos in real time—having internet access is no longer a luxury, it’s a necessity.

If you’re wondering, “How do I stay online while traveling abroad?”. We’ve got you covered. Here’s a simple breakdown of all the popular options, compatible with both iOS and Android, so you can choose what suits you best.

1. International Roaming

   Roaming allows you to use your existing mobile number abroad by connecting to foreign networks via your Thai provider, such as True or dtac. You can purchase roaming packages in advance through their apps.

   • Easy to use—no SIM swapping, just turn on your phone and go
   • Can be pricey if you don’t purchase a roaming add-on package but use standard roaming instead.
   • Ideal for those who want maximum convenience without fiddling with settings or SIM cards

   • More affordable than roaming, with a variety of packages
   • Requires SIM swapping, which can be inconvenient and risky if you misplace your original SIM
   • Great for budget-conscious travelers who don’t mind using a temporary number
