  • Buy local SIM card in USA: If your question is "where can I buy a SIM card in USA?", the answer is simple. You can do it in international airports, supermarkets and pharmacies with electronic section or in stores of mobile operators. T-Mobile, Verizon or AT&T are the most popular brands in the United States. This may be the best alternative if you are looking for the cheapest prepaid SIM card USA. The disadvantage is that you will not have internet as soon as you arrive in the North American country.
  • Tourist SIM card USA: If you feel panic thinking about not having internet from the first moment you set foot in the US, the best option is to buy a SIM card for USA online.

Roaming in USA: can I roam in the United States?

Roaming in the USA is available in almost all UK mobile tariffs, so you can easily roam in the United States with your actual phone without the need to switch SIM cards. This means you can use your data connection or make phone calls if you need to, which we can all agree is really convenient.

Data roaming charges in the USA vary greatly from carrier to carrier, as some companies offer bundles to roam overseas, while others charge you according to the data or minutes that you actually use during your stay in the United States.

Phone companies have different roaming partners, that is why the network used by your phone provider to roam in the USA can be different to the network used by other UK provider. All in all, you will have no problems with your connection in the States.

What is more, you do not even need to change anything, your phone will automatically connect to the North American mobile network, which according to your carrier or the State you are planning to visit will be different. This also happens when roaming in Mexico, its neighbouring country.

Is roaming in the USA free?

Roaming in the USA is not usually free, however some carriers like Vodafone or O2 offer free roaming in the USA, usually in their more expensive data plans which include different roaming bundles for free.

Our expert opinion

This is a piece of good news if you are a heavy user and you are going to take advantage of the GB and benefits included, however if you do not use your phone that much and you are choosing one of these deals just for the free roaming, you may be paying a lot for a service that is not really used on a daily basis.

Roaming in USA: How much does it cost?

Some carriers like EE, O2 or Three offer roaming bundles which help you roam at the United States at a lower price. Here you have some prices:

  • Vodafone roaming USA: For instance, Vodafone offers free roaming in the USA to their Xtra Plan customers, but only to those who have the most expensive Xtra deal, Unlimited Max + 4 Xtra benefits.
  • O2 roaming USA: On the other hand, O2 allows you to roam in the United States with the O2 Refresh tariffs over 90GB or SIM only tariffs over 100GB.
  • EE roaming USA: With EE company you will pay around £5 per day and you will have 500MB to spend during your travel to USA.
  • Three roaming USA: If you have a local tariff with Three you will pay £5 each day for using your mobile data.

As you can see, roaming in USA is not free in most UK phone companies, you will be charged up to £5 for every MB and up to £2 for every phone call. On the other hand, carriers like O2, EE or Three offer roaming bundles which allow you to roam overseas for a lower price. However, opting for a fixed price data plan, like an Holafly eSIM card, is one of the best options.

Wifi in USA: public or portable?

If you think the best way to connect to the internet while traveling in the United States is to use a Wi-Fi network, first think about what type of connection you are going to use.

Everyone knows about public wifi networks, but have you heard of pocket wifi? These are devices that companies usually rent to users so that they can connect to the internet from abroad.

The main advantage of portable wifi over public wifi is the security it offers. However, when compared to a international eSIM for the US, there are several disadvantages:

  • It is not a cheap option (it costs around £6/day).
  • You will have to wait for the company to send the device to your home address.
  • You will have to carry the device with you during your trip.
  • If you lose it or it breaks, you will have to pay compensation.

You won't have calls included either, that's why we at Roams think that the alternative offered by Holafly and its eSIM USA is more interesting. If you choose this option, the virtual card will arrive in your mailbox and to activate it you only have to scan a QR code. And now you can get it with a 5% discount if you enter the code ROAMS.

As for public wifi, the best thing about it is its price, as connecting to the internet via this means will cost you 0 euros. In addition, there are areas in the US such as New York where you'll find many free hotspots, but what are you going to do where there aren't any?

Public wifi is a method that can get you out of a jam at a moment's notice, but we don't think it's the best way to get internet in the US while you're visiting the country. We recommend that you only use it if you absolutely have to.

However, for us, the biggest limitation of this type of network is its vulnerability and danger. Be very careful if you use public wifi because the risk of having your data stolen is very high. Also, be aware that their speed and connectivity can be very unstable.

Mobile Internet in the USA: recommendations

At Roams we are here to help you, so we would like to take this opportunity to give you some recommendations before travelling to the United States. With these tips in mind and a good internet connection, you will be able to make the most of your stay in the United States:

  1. Carry a printed copy of the ESTA (Visa to enter the USA) or your travel reservations in case of any problems at immigration control. If you are asked for papers to corroborate your stay, you will be able to hand them in quickly.
  2. In the USA, electricity runs at 120V. Make sure your devices, including your mobile phone with US data, support this voltage.
  3. If you use a USA eSIM for tourists or any other method of internet connection, use the Yelp application to find the best accommodations or restaurants.
  4. Pay with your smartphone whenever you can. It's a good alternative to using credit cards, which are sometimes subject to fees.
  5. Check road conditions if you plan to rent a car to get from one state to another.
  6. Adapt your trip on a day-to-day basis. Even if you have planned your adventure, having internet on your mobile phone will allow you to check the tourist attractions in each area at all times, solve any accommodation problems or re-plan your route.
