Can tourists get a SIM card in the USA?

Yes, you can easily get a SIM card as a tourist in the USA. SIM cards are available at airports, mobile carrier stores, and retail outlets like Walmart or Best Buy. You don’t need any proof of identification to purchase one.

The starting price for a tourist SIM card in the USA is $40 for 10 GB of data for 30 days and can go up to $50-$60 for unlimited data plans. These plans usually include unlimited calls and texts as well.

Can you buy a SIM card without a plan in the US?

Yes, you can buy a SIM card in the US without a plan. Typically, these prepaid SIM cards are available from major mobile carriers like T-Mobile, AT&T, and Verizon, or from retailers like Best Buy and grocery stores. 

However, you will usually need to purchase a plan when you activate the prepaid SIM first—to make calls, use data, or send texts.

Many prepaid SIMs come bundled with pay-as-you-go options, allowing you to choose a flexible plan without a long-term contract.

In other words, while you can buy a SIM card without a plan, it won’t be functional until you activate it with a plan afterward.

How to get a prepaid SIM card in the USA for tourists? 

If you want to get the best prepaid SIM card in the USA, you’ll first need to know how and where to get one. 

When traveling to the United States, getting a prepaid SIM card is relatively straightforward.

For example, if you’re in a last-minute rush when you land, there are vending machines located in most airports where you can buy prepaid SIM cards.

The thing is, a tourist sim card in USA comes with a basic plan. And, that might not be enough  data for your traveling, scrolling heart.

In fact, visiting physical stores may be your next best option for finding good SIM card deals.

When visiting a store, let’s say T-Mobile or Verizon, you’ll have access to a wider selection of SIM card plans to stay connected while in the United States.

Just keep in mind, these plans are often targeted towards residents—long-term plans—you’ll likely struggle to find a travel package for your trip.

Plus, postpaid plans aren’t available for travelers—no matter the carrier! We’ve done the research so you don’t have to. 

Prepaid SIM cards vs. Postpaid SIM cards

Now that we’ve discussed how to get a SIM card in the USA, let’s differentiate between prepaid and postpaid options.

Prepaid SIM cards require upfront payment for a specific amount of data, talk time, and text messages. They are generally more flexible and accessible to visitors.

Postpaid SIM Cards: mean you pay for services after usage, at the end of a billing cycle. These plans often require a credit check and are primarily for US residents.

Let’s make some comparisons between both:

Where to buy a data SIM card for the USA?

As a tourist, your best option is a prepaid SIM card. Major carriers like Verizon, AT&T, and T-Mobile offer these cards at their stores nationwide.

No contracts are required, making them perfect for short-term visitors.

Keep in mind, you’ll need to purchase the SIM card upon arrival in the USA. Here’s where you can buy from:

Buy a SIM card from an international airport upon arrival

Major airports like New York (JFK), Los Angeles (LAX), and Orlando (MCO) often have kiosks or shops where you can buy SIM cards, many with international roaming plans available too. 

These kiosks are located in the arrivals area or near baggage claim. These offer a quick and convenient solution for travelers eager to connect upon arrival.

While the convenience is undeniable, it’s worth noting that prices at airports often tend to be higher than other options on our list—plus, you’ll likely need to be battling lengthy lines. 

Buy a SIM card from authorized retail stores

Retail stores of major carriers like AT&T, T-Mobile, and Verizon are widely available across the USA. These stores give you the benefit of direct customer service, and a wider choice of data plans.

If you have specific needs or questions, or you’re not too tech savvy, visiting a physical store can be a great shout. These stores are typically located in major cities and shopping malls.

Consider shopping for a SIM card at convenience stores

For a quick and easy solution, convenience stores like 7-Eleven, CVS, and Walgreens offer USA prepaid SIM cards for tourists.

While not boasting the widest selection, they provide a convenient option for last-minute purchases—and plenty of snack options while you’re there too!

Try electronics stores

Some electronics retailers like Best Buy and Fry’s Electronics carry prepaid SIM cards, especially those specializing in mobile phones.

These stores might offer competitive pricing or bundle deals. They also may have pocket WiFi for USA options for you to consider. 

However, not all electronics stores stock SIM cards, so it’s advisable to check before you make the trip.

What’s the best SIM card to use in the USA?

Holafly offers one of the best virtual SIM cards for the USA, providing consistent 4G speed, unlimited data, and easy top-up options.

It also offers this advantage in prepaid, so being a tourist, the purchase is much more direct. You’ll struggle to find providers offering unlimited data with this versatility.

If you don’t have a phone compatible with the virtual SIM card, you can find local options in the USA with unlimited data packages. AT&T and T-Mobile have unlimited data SIM cards, but only in 30-day options. 

These carriers are looking for long-term customers, so you won’t enjoy benefits or discounts if you don’t renew your plan.
