We know that not many people are familiar with unlimited data plans. That is why we will be telling you what unlimited data plans are, the limitations that you may encounter, and of course, how to get one of these plans with one of the largest telecommunications companies in the United States, that is, AT&T. Additionally, we will also tell you a little bit about the new eSIM. The perfect alternative to having an internet connection in a matter of minutes. Let’s get started!


What is unlimited data?

Surely, it has happened to you that you are using the internet on your device, and suddenly, you run out of data on your plan. So, you have to top up your phone to continue enjoying the internet connection. Well, this ends with the new unlimited data plans. Many cellular providers have opted to offer their users plans with which they can surf the internet without limits.

Likewise, many companies also offer unlimited data plans for specific applications. For example, for some streaming applications such as Netflix or HBO Max or for social networking applications. This allows customers to use those apps that consume a lot of mobile data without worrying about suddenly running out of data. 

Is unlimited data really unlimited?

One of the main concerns that many users have about those plans that offer unlimited data is if it will actually be unlimited, no matter how much data they consume. 

While you can always have an internet connection when using one of these plans, most companies have consumption policies.  This means that if you currently have an unlimited data plan, and you exceed a certain data threshold at the highest connection speed, then your internet speed may decrease. So, before purchasing any unlimited data plan, we recommend that you check the usage policies of the provider. So that you are aware of any limitations you may have. 

How to get unlimited data with AT&T in the USA

AT&T currently offers a number of plans, including those that offer unlimited data. As a tourist, you will be able to purchase those plans that are prepaid because, with these, you will not sign up for any subscription contract, annual contract or credit check.

To purchase one of AT&T’s unlimited data plans, you will first need to purchase a prepaid SIM card or eSIM from the company. You can do this through one of their physical stores. Through their online site or through certified providers, such as Best Buy. 

After getting the AT&T prepaid SIM card or eSIM, you can add one of the unlimited data plans through MyAT&T. And you will start enjoying the benefits of the purchased plan. Later we will explain in detail the unlimited data plans that AT&T offers and that you, as a tourist, can buy. 

AT&T SIM card

This company offers prepaid and postpaid SIM cards. However, as a tourist, you will only be able to get a prepaid SIM card, with which there will be no need to sign a contract. This can be purchased through an AT&T physical store, ordered online, or purchased from a local retailer.

If you purchase one through a physical store, it will usually be priced at $4.99. However, through the website, it is free. Remember that once you purchase a prepaid SIM card, you will be able to log into MyAT&T and set up the unlimited data plan you want to get. 

Finally, remember that in order to use one of these prepaid SIM cards in the United States, your cellphone must be unlocked. That is, it must be able to work with different carriers than the one in your country. 


On the other hand, if you currently have an eSIM-compatible cellphone and prefer to use this type of service, then with AT&T, you will also be able to do so. You will simply need to visit an AT&T physical store to purchase it, where you will be given all the information to activate it on your device. 

As with the prepaid SIM card, after purchasing an eSIM, you will need to add the prepaid data plan that you will be using with the virtual SIM card. This can be done through the AT&T website. Also, it is recommended that if you only use the plan for one month, make sure you don’t have the autopay option activated. 

How much does an unlimited data plan from AT&T cost?
