eSIM for Argentinians traveling to the USA — Internet without roaming

If you're traveling from Argentina to the United States, you already know that roaming from your local carrier can be a very unpleasant surprise when you return: bills for tens or even hundreds of dollars/euros for just a few days of data. There's a much smarter solution: a dedicated eSIM for the United States.

In this guide, we'll explain exactly how it works, how much you can save compared to roaming from your Argentine carrier, and how to activate your PuraSim eSIM before boarding the plane.

With PuraSim, you'll have local data in the United States from the moment you land, at local prices, with no commitments and without changing your physical SIM card.

Roaming from Argentina to the United States: what it really costs

Argentine carriers offer international roaming packages for the United States, but prices are rarely competitive. Depending on your carrier, a day of data in the United States can cost you between 15-25 USD/EUR per day.

Let's look at a real example: if your trip to the United States lasts 10 days and you use data moderately (maps, messages, social media), with traditional roaming you could pay between 150 and 250 euros/dollars just for connectivity. With a PuraSim eSIM for the United States, that same usage would cost a fraction.

In addition to the cost, roaming has other limitations:

• Reduced speed often to 3G or even 2G
• Very low daily data cap before your speed is cut
• You need to activate the service before leaving (and pay for it even if you don't use it)

A PuraSim eSIM eliminates all these problems: you pay once for the GB you need, you get real 4G/5G speed, and you activate it only when you need it.

How an eSIM for the United States works

An eSIM (embedded SIM) is a digital SIM that lives inside your phone. There's no physical card to insert: you download the carrier profile via a QR code, and you're all set. Your phone can have several eSIMs installed simultaneously and switch between them in seconds.

For travelers from Argentina to the United States, the process is as follows:

1. Purchase your data plan on purasim.com before you leave
2. Receive the QR code by email
3. Install the eSIM on your phone from home (in 5 minutes)
4. Upon landing in the United States, activate the eSIM and you'll have local data
5. Your Argentine SIM will still work for receiving calls and SMS

No need to go to any store. No need to wait in line. No need to look for a phone shop upon arrival at the US airport. You arrive, and you already have internet working.

How many GB do you need for the United States?

For a trip from Argentina to the United States, our recommendation is 15-20 GB for 10 days. This is sufficient for most common uses: Google Maps throughout the day, WhatsApp with family and friends in Argentina, Instagram, occasional searches, and some occasional video calls.

Breakdown of typical daily consumption:

• Google Maps actively navigating: ~150 MB/day
• WhatsApp with messages and photos: ~100 MB/day
• Instagram and social media (no video): ~300 MB/day
• Searches and websites: ~100 MB/day
• Estimated total: 600-700 MB/day for moderate use

If you're going to work remotely, make frequent video calls, or upload real-time content, consider a higher plan. PuraSim plans have top-up options available if you run out, so you can always extend.

Tip: Roaming from Claro or Personal Argentina in the USA can cost double the airfare; an eSIM is the most obvious travel saving.

How to activate your eSIM before your flight

The best part about PuraSim eSIMs is that you can have it ready before leaving Argentina. The installation process takes about 5 minutes and only requires WiFi:

1. Check compatibility: ensure your phone supports eSIM (iPhone XS or newer, Samsung Galaxy S20+, Google Pixel 3+ and many more).
2. Purchase your plan on purasim.com. Select the United States as your destination and the GB plan you need.
3. Install the eSIM: open the email with the QR code and go to your phone's Settings to scan the code and download the profile.
4. Configure the eSIM: give it a recognizable name (e.g., "PuraSim United States") and make sure it's configured for data but NOT for calls or SMS (keep those on your Argentine SIM).
5. Activate upon arrival: on the plane, you can have the eSIM installed but inactive. Upon landing in the United States, go to Settings → Mobile Data and activate the PuraSim eSIM.

In less than 5 minutes after landing, you'll have full data in the United States without even leaving the airport.

Tips for travelers from Argentina to the United States

Beyond connectivity, here are some specific tips for travelers from Argentina:

• Download everything before you leave: offline maps of New York, Miami, Las Vegas, and Los Angeles on Google Maps, playlists on Spotify, Netflix episodes for the flight. You won't have data during the first few hours of your flight.
• Notify your bank: many Argentine banks block transactions in the United States for security reasons. Inform them of your trip to avoid having your card blocked at the most inconvenient time.
• WhatsApp will work perfectly: with the active eSIM, you can call and talk to family and friends in Argentina without additional international call charges.
• Keep documents offline: scan your passport, travel insurance, and reservations and save them on your mobile. If there's a moment without data, you'll still have access.

And remember: Roaming from Claro or Personal Argentina in the USA can cost double the airfare; an eSIM is the most obvious travel saving.

With PuraSim connected, your trip from Argentina to the United States starts seamlessly from the very first moment.
