How to get a prepaid SIM card in the USA?

If you want to get the best prepaid SIM card in the USA, you need to know how to get one when you travel. 

When traveling to the United States, getting a prepaid SIM card is somehow easy. There are different vending machines located in a variety of airports where people can get different prepaid SIM cards.

The thing is, these prepaid SIM cards come with a basic plan. And that might not be enough for what travelers need, that’s why visiting physical stores comes as a handy solution to get SIM cards.

When visiting a store, let’s say T-Mobile or Verizon, people will have access to different plans to stay connected while in the United States, but it will be harder to get a SIM card there.

Also, postpaid plans are not available for travelers. No matter the carrier, none of these actually provide postpaid plans to travelers.

Prepaid SIM cards vs. Postpaid SIM cards

Now that we have mentioned the overall process of getting a SIM card in the USA, what are the differences between the available data plans offered by carriers like Verizon or T-Mobile with a physical SIM card?

A prepaid SIM card USA already has an established price upon people buying one. As said before, these are available on vending machines in many places, such as international airports or even at convenience stores.

People can also get a SIM card from a physical store, but as travelers, the process will be more complicated. Only prepaid SIM cards will be available.

Postpaid plans are available for locals, which means there’s no way of getting SIM cards with any of these plans. 

Now that we have this clear let’s make some comparisons between both:

Prepaid PlansPostpaid plans
People can recharge these eSIMs to use it as a pay-as-you-go serviceUsually requires to get bundles to get a data plan
Accessible for travelers not only in physical stores but at convenience stores and vending machinesMore expensive compared to prepaid plans due to what it offers
Ideal for avoiding roaming charges when traveling to the United StatesNot ideal for avoiding roaming when abroad as it requires monthly payments to work
It’s hard to find unlimited data prepaid SIM cardsSome postpaid plans offer unlimited data packages

Where to buy a data SIM card for the USA?

Buying a USA tourist SIM card will keep you connected throughout your trip. Forget about paying excessive charges for international roaming services in the USA or renting Pocket WiFi. With the data SIM card, you can use your cell phone during your trip. And you’ll never worry about losing connection again.

When traveling to the USA, the local options you can buy as a tourist are prepaid SIM cards. Carriers such as Verizon, AT&T, or T-Mobile sell these SIM cards in their stores nationwide. You do not need to sign contracts to buy them; they are ideal for travelers. However, you will not have internet until you arrive in the country and find a store. Finally, to help you choose, you can review this checklist.

  • Physical stores: If you want to wait until you arrive in the United States to stay connected with a prepaid SIM card, physical stores are your go-to option. As said before, convenience stores are great places to find these SIM cards; the same goes for airports like LAX. Unlocked phones and valid IDs are a requirement in this case.
  • Online stores: If you want to enjoy similar benefits to using an AT&T, T-Mobile, or Verizon SIM card, online stores are a great option for travelers. These stores offer a variety of data plans, and the network coverage will be similar to using a local carrier.

AT&T SIM card USA

This is one of the most used mobile operators in the United States. So, with them, you can acquire a prepaid SIM card for free and recharge any data plan. This makes it one of the options when looking for the best prepaid SIM card USA.

You can not buy on their website as a tourist, so you must look for it when you arrive in the country. You can choose between different plans depending on your needs, and that can help you answer how much does a SIM card costs.

  • 5 GB high-speed data for 30 days at $30
  • 15 GB high-speed data for 30 days at $40
  • Unlimited data for 30 days at $65
  • 16 GB/Month high-speed data for three months at $99
  • Unlimited data for 12 months at $300

You also can share data with nearby devices if needed. If the plan you choose is not an unlimited data plan, the data you do not consume in one period can roll over to the next period as long as you renew it. Also, you can purchase AT&T prepaid SIM cards through their website, in a physical store, or even in supermarkets such as Walmart or Best Buy. In any of the cases when hiring their services, you will have additional benefits such as

  • Unlimited talk and text

3. T-Mobile

T-Mobile SIM card USA

On the other hand, we have T-mobile. With this local operator, you will need to pay for the T-Mobile USA prepaid SIM card, and you will need to purchase it through one of their physical stores or supermarkets, such as Walmart and Target. As for the prepaid offers:

  • 10 GB high-speed data for 30 days at $40
  • Unlimited data for 30 days at $50
  • Unlimited data plus for 30 days at $60

If you want to add services to neighboring countries like Canada or Mexico, you must pay an extra fixed amount between $5 and $15. The difference between the unlimited plus and unlimited plans is that one allows high-speed data sharing, and the other does not. Other services that are added to these data plans:

  • Unlimited domestic talk and text
  • Domestic 5G handset data on T-Mobile network
  • Caller ID
  • WiFi calling
  • Data Maximizer

4. Verizon

Verizon SIM card USA

Verizon is another well-known mobile operator in the United States. However, one particularity with this USA carrier is that their SIM card is not compatible with all types of phones. For this reason, to purchase a prepaid SIM card with them, you must bring your device and confirm that you can use one of their data plans. 

  • 15 GB high-speed data for 30 days at $45
  • Unlimited data for 30 days at $60
  • Unlimited data plus for 30 days at $70

Again, the difference between the two unlimited data plans is the amount of GB you can share a mobile hotspot at high speed. You can enjoy discounts for Auto Pay or loyalty after three months of use, but this is focused more on resident customers than tourists. Considering this, in addition to the discounts you have services such as

  • Access to 5G Verizon network coverage with compatible devices
  • Mobile hotspot to share data with other devices
  • Unlimited calling and texting in the USA
  • Unlimited text messaging from the USA to more than 200 countries and territories worldwide.
  • Coverage in Mexico and Canada 
  • Digital security with personal data anti-virus, anti-malware, and secure browsing.

Another option we have in the USA is Lycamobile, a virtual operator that works with the T-Mobile network in the country. To buy one of their prepaid SIM cards, you must access their website and enter the Zipcode of the city where you are. After that, it will tell you if they have coverage in the area and the New Lines deals they offer.

  • 250 MB for 30 days at $15
  • 2 GB for 30 days at $19
  • 3 GB for 30 days at $23
  • 6 GB for 30 days at $29
  • 9 GB for 30 days at $33
  • 15 GB for 30 days at $39
  • 40 GB for 30 days at $49
  • 60 GB for 30 days at $59

The connection speed is 5G if your device is compatible and you are within the network coverage. After you consume the data package, you cannot continue browsing unless you recharge your SIM card. Thanks to Lycamobile’s alliances in other countries with their data packages, it is also included:

  • Unlimited nationwide talk and text
  • You can use your minutes and messages from the USA to 85 different countries.
  • No contracts are required. Just have a US address to receive the SIM card.

Finally, we came across another virtual operator from the USA that uses the AT&T network to connect with their prepaid SIM cards. As in other cases, they do not require a contract to buy them, but we must have an address to receive the SIM card. They have four monthly plan options to choose from

  • 500 MB high-speed data for 30 days at $15
  • 1 GB high-speed data for 30 days at $20
  • 10 GB high-speed data for 30 days at $30
  • 22 GB high-speed data for 30 days at $40

There is no minute limit, but you can only call ten different numbers per monthly cycle. In addition to this benefit, you can add other services such as.

  • Unlimited local texting and messaging

On the other hand, if you do not 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. Also, these carriers are looking for long-term customers, so you will not enjoy benefits such as discounts if you do not renew the plan every month.
