List Of Best American SIM Card Companies

It’s not easy to find a SIM card that is not only compatible with your Samsung Galaxy or another phone model but also provides reliable service. That’s why we spent over 10 hours analyzing all of the budget-friendly options before selecting the top six SIM cards. Every SIM card on this list is prepaid, which means you won’t have to pay a monthly charge or commit to a contract. You simply pay for what you require upfront, and you can easily reload if you require more. In this day and age, a SIM card may be purchased for as little as $9.99. Furthermore, all cards are nano and micro-sized, making them compatible with today’s cell phones and smartphones. Finally, all cards are intended to work with 3G and higher networks. Everything we chose is also 4G compatible. You may also wish to invest in the best iPhone battery cases to increase your battery life. These SIM cards are simple to set up, and you’ll be making critical phone calls in no time. Check out our assessment of the best cell phone plans if you need a plan for your phone.

AT&T’s Prepaid SIM is the greatest choice since it has the finest coverage — in the United States, Canada, and Mexico — and it comes with unlimited calling, texts, and data for a set amount of time. Of course, it isn’t the only option on our list of the best SIM cards. If you want to discover more about our top pick and the other cards we chose, keep reading. You’ll have a phone that’s right for you at the conclusion of this list.

AT&T Prepaid SIM

Activating AT&T gives you unlimited call, text, and data throughout the United States, Canada, and Mexico (up to 30 total). AT&T’s GSM unlocked SIM supports 3G and 4G networks. All of this comes at a low cost, making it an excellent choice for everyone from travelers to temp workers to prepaid consumers.


  • Unlimited everything 7 to 30 days
  • Works in the U.S., Canada, and Mexico
  • International Roaming included within the above countries


  • Must be set up at least 3 days before a trip or activation
  • No international phone support outside the three main countries
  • Supports Nano-SIM size only

The AT&T network is not only well-known, but also trustworthy in many locations in the United States, Canada, and Mexico, making this temporary phone SIM an excellent choice for anyone traveling inside those boundaries. AT&T and Samsung are both well-known companies. (For more information, see our Samsung Galaxy S9 and S9+ Smartphone Review.) You get unlimited talk, text, and data for a set amount of time for a one-time fee. You can buy up to 30 days of access at a time, starting at 7 days. However, you must register the SIM through AT&T’s network at least three days ahead of time, so keep that in mind if you’re planning a vacation. Another must-have for travelers is the finest portable phone charger.

The SIM supports 3G, 4G, and 4G LTE on most bands and works with GSM and CDMA networks. If you stay within the supported countries, roaming is covered. Of course, that is the card’s major flaw: it doesn’t support international sim cards outside of North and Central America. Travelers who need access to a cell network while abroad will have to search elsewhere. Take a look at Google Fi instead if you want to compare this to another choice.

Verizon 3-in-1 Postpaid/Prepaid SIM

While the Verizon 3-in-1 postpaid/prepaid SIM card does not come with service out of the box, it is intended for Verizon cellular customers who are already or plan to become Verizon customers. Simply insert the SIM card, register on Verizon’s website (choosing whichever prepaid plan you like), and you’re ready to go. All cell phone plans include unlimited talk, text, and data usage. You can also subscribe to international plans, which cover over 185 countries outside of the United States.


  • International coverage support
  • Supports Nano/Micro/Standard-SIM sizes
  • All postpaid and prepaid plans offer unlimited talk, text message and data


  • Verizon only; not compatible with MVNO services
  • No plan/service included; just the SIM card (plans start at $35)

The Verizon 3-in-1 postpaid/prepaid SIM card is for consumers who do not have a current Verizon subscription, such as travelers or those who need temporary access to compatible mobile networks. The SIM card does not include service; instead, you must register and select a plan on Verizon’s website. It’s also incompatible with any other networks, including MVNOs (mobile virtual network operators) like Cricket, Boost, and others.

The good news is that all Verizon postpaid and prepaid plans include unlimited talk, text, and data on 4G LTE networks that are supported. Coverage is mostly available in the United States, Canada, and Mexico. International connectivity, on the other hand, is available for a fee, with support for over 185 countries globally.

Finally, the card may be customized to fit in nano, micro, and normal size SIM card slots. It comes with a larger card attached to it, which you punch out to the size you require.

SpeedTalk Mobile Preloaded SIM

While the SpeedTalk Mobile Preloaded SIM is only good for the United States, it does come with a free month of service — or 250 units in the company’s mobile currency. The card also connects to 3G, 4G, and 4G LTE GSM networks and supports Nano, Micro, and Standard SIM sizes.


  • Free month of service
  • Supports Nano/Micro/Standard-SIM sizes

  • Requires debit or credit card to activate

The SpeedTalk SIM uses GSM bands to connect to the company’s 3G, 4G, and 4G LTE networks. Unfortunately, it only supports service in the United States; however, a coverage map is provided to double-check which locations are covered. If you want access to foreign or non-domestic (Canada and Mexico) networks, you’ll need to acquire a new card. Even with low coverage, if all you need is a USA SIM card, this will work.

SpeedTalk’s SIM is the cheapest buy-in on the list, at just over $5, and it comes with the equivalent of one month of free service. A unit-based mechanism is used by SpeedTalk. The card comes with 250 units, each of which represents one minute of conversation, text, or data. One unit, for example, is one minute of discussion, one letter, or one megabyte of data. To use the card, there are no contracts, no credit checks, and no activation fees. To cover overages and maintain service, you will need to supply a credit or debit card at the time of activation. This is a compelling reason to learn more about the best smartphone plan.

Cricket Wireless Prepaid SIM Card Kit

Cricket Wireless’ Prepaid SIM has some of the finest coverage of any MVNO, supporting up to 99 percent of all Americans. In the United States, Mexico, and Canada, it also offers 4G LTE speeds, and you may load up units using Cricket’s mobile companion app.

The card does not feature any gratis services. However, unlimited call and text options begin at $30 per month. This is ideal if you require an unlimited plan but are on a tight budget. You can choose your subscription plan after you activate the card via Cricket’s Breeze-Thru mobile app. Cricket claims to cover up to 99 percent of the US population, which is astounding for an MVNO. Cameras are equally crucial, so check out our list of the top smartphone cameras.

SpeedTalk Mobile SmartWatch SIM

SpeedTalk Mobile’s SmartWatch SIM, unlike many of the other SIM cards on this list, is designed for wearable technology. As a result, it’s suitable for usage with GPS trackers, smartwatches, and other similar devices. For up to 30 days, it offers 50 minutes, 100 SMS, or 100MB of data as complementary units. The service is currently only offered in the United States.

A US phone number will be automatically produced when you activate the card, which requires a debit or credit card linked to your account. This also implies that if you already have a phone number, this SIM card will not sync with it. You’ll have to start from the beginning.

Each card comes with a 30-day subscription, but you can extend it using SpeedTalk Mobile’s services. Plan ahead of time because GPRS and data settings can take up to 24 hours to sync properly. You will be able to avoid roaming charges with this SIM card because it includes roaming. Some folks, on the other hand, simply want to use the best-unlocked phone available.

T-Mobile Prepaid SIM Starter Kit

T-prepaid Mobile’s SIM is remarkably similar to the others on the list in terms of functionality. It has some of the best prepaid unlimited data plans on the market, with options starting at $40 for unlimited talk, text, and up to 10GB of LTE data. Tmobile’s tourist plan, for example. It also works with Nano, Micro, and Standard SIM cards.

  • Meant for U.S. only, but works in Mexico and Canada if you have a credit card with a U.S. address.

T-Prepaid Mobile’s SIM beginning set includes a tri-compatible card that can be used with the wireless carrier’s 4G LTE networks and comes in Nano, Micro, and Standard-SIM sizes. As a result, the card is only compatible with GSM bands, ruling out CDMA-based phones.

It’s mostly for US coverage, although numerous Amazon reviewers have reported success in Canada and Mexico – you’ll still need a credit or debit card with a US address.

Furthermore, there is no service included with the SIM purchase. Activation will need you to select a T-Mobile subscription plan. There are no activation costs, no contract obligations, and unlimited talk, call, text, and data options are available if desired.
