Staying Connected Before Your U.S. Trip: How to Buy a Prepaid SIM Card or eSIM in Advance So You're Online from Day One

Before you head to the U.S., making sure you can stay connected is an essential part of your travel plans. Whether you're a new immigrant who has just arrived or a traveler planning a visit, knowing how to buy a prepaid SIM card (Prepaid SIM Card) or eSIM in advance will help you get online as soon as you arrive and avoid expensive international roaming fees.

What are prepaid SIM cards and eSIMs?

  • Prepaid SIM card (Prepaid SIM Card): A physical SIM card you pay for in advance, usually with a set allowance of calls and data. You can buy one after you arrive in the U.S. or order it online ahead of time.
  • eSIM (Embedded SIM): A virtual SIM built into your device, so there's no physical card to insert or remove. You can buy an eSIM online before you leave, install it on your phone, and start using it once you arrive in the U.S.

How to buy a prepaid SIM card or eSIM before you leave

  1. Check that your device is compatible
    • eSIM: Make sure your phone supports eSIM. Most smartphones released in recent years, such as the iPhone XR and later models and some Android devices, support eSIM. To check, look in your phone's settings for a "Cellular plan" or "Mobile network" option.
    • Prepaid SIM card: Make sure your phone is unlocked (Unlocked) so it can use SIM cards from other carriers. You can contact your carrier to check whether your phone is unlocked.
  2. Choose the right plan
    • Aerobile: A company that specializes in international data solutions and offers a range of U.S. prepaid SIM card and eSIM plans. Before you leave, you can pick a plan from their online store and choose to have a physical card mailed to you or receive the eSIM by email.
    • Other online platforms: Travel platforms such as Klook and KKday also offer U.S. prepaid SIM card and eSIM plans, so you can compare and choose based on your needs.
  3. Buying and installing
    • Prepaid SIM card: After you order online, the physical card is mailed to your address. Before you leave, insert the card into your phone and follow the instructions to set it up.
    • eSIM: After you buy it, you'll receive an email with a QR code. Scan the QR code with your phone to install the eSIM on your device. It's best to do the installation on a stable internet connection so it activates smoothly.

Things to watch for

  • Choosing a plan: Different plans offer different amounts of data, call time and validity periods. Choose based on how long you're traveling and how you'll use your phone.
  • Network coverage: The major U.S. carriers are AT&T, T-Mobile and Verizon. Coverage can vary by region. If your trip includes remote areas, choose a carrier with wider coverage.
  • Customer service: Choose a provider with live customer service around the clock, such as Aerobile, so you can get help quickly if something goes wrong.

Getting your phone plan ready ahead of time not only lets you get online as soon as you arrive in the U.S., it also helps you avoid expensive international roaming fees and makes your trip smoother and more enjoyable.
