Types of USA sim cards for tourists

There are 02 main types of American SIM cards:

  • Local USA SIM cards: These sim cards are issued by major US-based mobile network operators such as T-Mobile, AT&T, and Verizon. They are designed primarily for US residents and long-term visitors. Tourists often choose prepaid plans due to their convenience and lack of long-term contracts.
  • International SIM cards (roaming SIM cards): These cards are designed specifically for international travelers and offer international global roaming features. This means you can use your phone in the USA and/or other countries, depending on the specific plan you choose. Keep in mind that some prepaid SIM cards for US travel do not include calls or texts, but data-only. However, you can still stay in touch with people back home by using voice apps like Skype, WhatsApp, etc.

For most tourists visiting the USA, international USA SIM cards are the recommended choice.

Upon choosing international USA SIMs, be noted that there are two types of international SIM cards for USA: physical SIM and virtual SIM cards (eSIM).

If your phone is unlocked and compatible with eSIM, it is recommended to choose eSIM USA for the most convenient experience.

But if your phone is of old models that do not work with eSIM, choosing a traditional SIM card for USA travel is still good enough.

III. Where to Buy a Tourist SIM Card for the USA?

Where to buy a SIM card for USA

You can buy SIM cards for US travel in 03 ways:

1. Buy at airports after arrival

You can buy SIM cards for USA in kiosks and shops upon arrival at the airports like LAX, SFR,… The shops of carriers like AT&T, T-Mobile etc. are often located near baggage claim or the arrivals area with staff who can help you navigate plans and activate your card. Then, the SIM card can be used right away. No shipping delays and also have chance to try before buying.

However, that convenience often comes with high prices and probably limited data.

For example, you will be surprised if you find yourself staring down a $50 SIM card with a measly 1GB of data

You may also encounter a wall of SIM card options, leaving you unsure which to choose.

On the other hand, if you fly into a smaller regional airport, you should have a backup plan since you cannot find a SIM card there.

Our advice is that if you do not need a SIM card the moment you get out of the plane, skip the airport kiosks to get better deals and a wider selection.

Important Note: In fact, buying a prepaid SIM card at international airports in the United States can be overwhelming. Some airports (like JFK in New York) do not have kiosks for mobile network operators. You just can buy SIM cards through vending machines.

2. Buy online before departure

You can be prepared before your trip by buying SIM cards for USA from online travel SIM providers or ecommerce platforms like Amazon, eBay, etc. They offer services to deliver the SIM to international addresses. But check if your address is of their supporting addresses

Buying SIM online helps you avoid the inflated prices found at airport kiosks and browse a wide range of carriers and plans at your leisure.

Notes:

  • Be aware of shipping time to ensure the SIM arrives before your departure or in time for your arrival in the US.
  • You will likely need to activate the SIM card yourself without in-person help.

This buying option is right for you if you like to have things organized before traveling and are comfortable with self-setup. To avoid waiting time of physical SIM cards, you can choose to buy United States eSIM online. The eSIM plan information will be sent to you via email within 5-10 minutes after payment. Just need to scan the QR code and you are good to go.

3. Buy in US cities at official stores, convenience stores

If you want to have a wide range of plan options, buying US SIM cards in retail stores in the United States is a good option. However, be prepared to invest a little time in the process.

Unlike airport kiosks, retail stores offer a diverse selection of SIM cards from major carriers, smaller providers, and everything in between.

The plan prices are also competitive. Supermarkets and electronics stores tend to offer particularly competitive prices.

For example, you can visit official stores of US mobile network operators like T-Mobile, AT&T, or Verizon for the most comprehensive selection of plans from that specific carrier.

Supermarkets like Walmart, Target, and Best Buy, pharmacies like CVS and Walgreens, or convenience stores like 7-Eleven often carry a variety of prepaid SIM cards and tend to offer particularly competitive prices.
