eSIM for the USA for 10 Days – Which XOXO WiFi Plan Should You Choose? Comparison of Options, Prices, and Step-by-Step Activation Guide

A 10-day trip to the United States usually means intensive sightseeing, traveling between cities, and frequent smartphone use. Google Maps, Uber, restaurant searches, accommodation bookings, messaging apps, and social media quickly make internet access in the USA one of the essential tools during your trip.

One of the most convenient ways to get internet abroad is an eSIM. You do not need to replace your physical SIM card or look for a mobile operator’s store after arrival. You can install the profile before departure, and the plan activates after the first connection to a supported network in the destination country.

If you are planning a 10-day trip, however, an important question arises: which eSIM for the USA should you choose, and how many GB will you actually need? Below, we compare the available XOXO WiFi plans, their prices, and explain which option best suits different ways of using mobile data.

eSIM for the USA – how does mobile internet work without a physical SIM card?

An eSIM (embedded SIM) is a digital version of a traditional SIM card. Instead of inserting a plastic card into your phone, you install a mobile operator profile directly on your device, usually by scanning a QR code provided after purchase.

For a trip to the United States, this solution is particularly convenient. You can buy an eSIM online before leaving Poland, install it before your trip, and switch your mobile data to the USA profile after landing. What is more, you can store several eSIM profiles on one device, making it easier to use different data plans on different trips. The eSIM module itself is built into the device and cannot be physically removed like a traditional SIM card, which also improves security.

This means you do not have to:

• look for a local SIM card at the airport,
• remove your Polish SIM card,
• sign a contract with a US mobile operator,
• rely exclusively on hotel or public Wi-Fi,
• use standard roaming without checking the costs beforehand.

XOXO eSIM for the USA uses the infrastructure of networks including T-Mobile and Verizon, and where the relevant technology and coverage are available, 5G connectivity may also be available.

How much mobile data do you need in the USA for 10 days?

There is no single data plan that will suit everyone. Someone who mainly uses Google Maps and WhatsApp may consume several times less data than a traveler who regularly uploads videos to Instagram or uses a mobile hotspot.

Before buying mobile internet abroad, it is therefore worth considering how you normally use your phone.

3 GB – for light data users

A 3 GB plan may be enough for 10 days if you mainly use your phone for:

• Google Maps and navigation,
• checking routes,
• Google searches,
• WhatsApp and Messenger,
• email,
• checking attraction opening hours,
• occasionally ordering an Uber or Lyft.

That gives you approximately 300 MB per day if the data allowance is used evenly.

A good way to reduce mobile data usage is to download offline maps before departure and use Wi-Fi for app updates and uploading larger numbers of photos.

5 GB – the best balance for most tourists

For a typical 10-day holiday, 5 GB is a much more versatile option.

In addition to maps, messaging apps, and web browsing, you can use Instagram more freely, check Booking.com, browse photos, use airline apps, and occasionally watch short videos.

That gives you an average of around 500 MB of data per day.

Another advantage is the relatively small price difference compared with the smallest plan. If you want greater peace of mind, 5 GB will often be more practical than constantly trying to save every megabyte.

10 GB – for active users

If you expect to use your phone intensively throughout your trip, it may be worth choosing a 10 GB USA eSIM.

This package is particularly suitable for:

• frequent Instagram and Facebook use,
• uploading photos and short videos,
• watching online content,
• regularly searching for accommodation and attractions,
• using mobile internet during a US road trip,
• occasionally sharing your connection via hotspot,
• working with email and online documents.

For a 10-day stay, this works out at approximately 1 GB of data per day.

50 GB – for heavy use and hotspot sharing

The largest package mainly makes sense if your smartphone will partially replace a regular internet connection.

A 50 GB plan may be worth considering if you intend to:

• regularly share your connection with a laptop,
• work remotely,
• participate in video calls,
• use streaming services intensively,
• upload large numbers of photos and videos to the cloud,
• use mobile internet for many hours every day.

For the average tourist on a 10-day holiday, however, this will usually be far more data than necessary.

XOXO WiFi USA eSIM – plan and price comparison

The current offer includes several options that differ in their data allowance and validity period.

For a trip lasting exactly 10 days, the first three options are particularly relevant.

3 GB for PLN 37 is the budget option. 5 GB for PLN 45 provides a larger safety margin for only a small additional cost, which is why it may be the most cost-effective option for most tourists. 10 GB for PLN 75 is a better choice if you expect to use mobile internet intensively.

Which eSIM plan should you choose for a 10-day trip to the USA?

The simplest recommendation is:

Choose 3 GB if you mainly use mobile internet for maps, messages, and basic web searches.

Choose 5 GB if you want to use your phone normally without constantly monitoring your data allowance. For the average tourist, this is the most versatile option.

Choose 10 GB if you use social media intensively, frequently upload photos, are planning a road trip across the USA, or expect to occasionally share your connection with another device.

Choose 50 GB if you are planning to work remotely, frequently use a hotspot, or consume large amounts of mobile data.

In practice, for a standard 10-day holiday, 5–10 GB should provide enough data for the vast majority of travelers.

eSIM for the USA – step-by-step activation guide

One of the biggest advantages of eSIM is that you can prepare your mobile internet before your trip even begins.

Step 1. Check whether your phone supports eSIM

Before purchasing a plan, make sure your device supports eSIM technology and does not have a SIM lock that prevents it from connecting to another mobile operator.

Step 2. Buy the right XOXO eSIM plan

Select the USA as your destination and choose the amount of data you need.

After placing your order, the QR code and installation instructions will be sent to the email address provided.

Step 3. Install the eSIM before leaving Poland

It is best to install your eSIM before departure while connected to a stable Wi-Fi network.

The QR code is unique, so once the profile has been installed, you should not delete it from your phone.

Step 4. Select the eSIM for mobile data after arrival

In your mobile network settings, select your USA eSIM as the source of mobile data.

If you want to reduce the risk of your Polish mobile operator charging you for data usage, disable mobile data on your primary SIM card.

Step 5. Enable data roaming on the eSIM

This is a particularly important step.

Data roaming must be enabled for the XOXO eSIM, because the profile may connect to partner networks in the USA.

Enabling data roaming on the eSIM does not mean that data roaming is enabled on your Polish SIM card. These are two separate profiles.

Step 6. Wait for the phone to connect to a US network

The plan activates automatically after the first connection to a supported network in the destination country.

Once your phone has connected to the network, you can start using the internet according to your selected package.

eSIM for the USA on iPhone – key settings

On an iPhone, the setup usually looks like this:

Settings → Cellular / Mobile Service → Add eSIM → Use QR Code.

After arriving in the USA:

• enable the eSIM profile,
• select it as your mobile data line,
• enable data roaming for the eSIM,
• disable “Allow Cellular Data Switching” if you want to prevent the phone from automatically using data from your primary SIM.

The exact names of individual options may vary slightly depending on your iOS version.

eSIM for the USA on Android – how to enable mobile internet

On Android, the exact path depends on the device manufacturer. In most cases, go to:

Settings → Connections / Network & Internet → SIM Manager → Add eSIM.

Then scan the QR code.

After arriving in the USA, set the eSIM as the SIM responsible for mobile data and make sure that data roaming is enabled for this profile.

What should you consider when choosing an eSIM for the USA?

Price should not be the only factor. Before purchasing an eSIM, check:

• how many GB are included,
• how long the package is valid,
• when the validity period begins,
• whether top-ups are available,
• whether hotspot sharing is supported,
• which networks the eSIM uses,
• whether your phone supports eSIM,
• whether the package is data-only or also includes traditional calls and SMS,
• whether customer support is available.

With XOXO WiFi, hotspot sharing is available, and top-ups are also available for most packages. Customer support is provided in both Polish and English.

Hotspot with an eSIM in the USA – can you share your internet connection?

Yes. XOXO eSIM allows internet sharing with other devices on supported plans.

You can therefore use your smartphone as a hotspot for a laptop or tablet.

However, remember that a computer can consume mobile data much faster than a smartphone. Cloud synchronization, system updates, and video calls can use several GB within a short period of time.

If you plan to use a hotspot regularly during your 10-day trip, 10 GB will be a safer minimum than 3 or 5 GB. For intensive remote work, you may want to consider a larger package or a mobile router.

What should you do if your eSIM does not connect to the internet in the USA?

In most cases, connection problems are caused by phone settings rather than the eSIM itself.

If the internet does not work after arrival:

1. Check that the eSIM profile is enabled.
2. Set the eSIM as your mobile data line.
3. Enable data roaming on the eSIM profile.
4. Turn airplane mode on for several seconds and then turn it off again.
5. Restart your phone.
6. Check whether the device has connected to a supported network.
7. If required for the specific package, check the APN settings.

Do not immediately delete the eSIM profile. The installation QR code is unique, so deleting an installed profile may prevent you from using it again.

eSIM or roaming in the USA – is it worth it?

The USA is not covered by the EU Roam Like at Home rules, which means the terms of using a Polish SIM card are different from those in countries such as Spain, Italy, or Greece.

Before departure, you should therefore check your mobile operator’s roaming rates and available roaming packages.

One of the main advantages of an eSIM is predictability. You purchase a specific amount of data at a fixed price and do not have to rely on standard roaming from your Polish operator throughout the trip.

For someone traveling alone for 10 days, PLN 37–75 for a 3–10 GB plan can be a convenient way to secure enough mobile data for navigation, communication, and sightseeing.

How can you reduce mobile data usage while traveling in the USA?

Even with a 5 GB or 10 GB package, it is worth configuring your phone properly.

Before departure:

• download Google Maps for offline use,
• disable automatic app updates over mobile data,
• limit automatic photo and video cloud synchronization,
• lower the quality of music and video streaming,
• download playlists, podcasts, and TV shows before your trip,
• perform large updates over trusted Wi-Fi,
• monitor your data usage in your phone settings.

These simple steps can significantly extend the life of your data allowance.

US phone number – when do you actually need one?

When choosing an eSIM for the USA, it is worth checking whether the package includes data only or also provides a local phone number, traditional voice calls, and SMS. These are separate services, and simply using an eSIM does not automatically mean that you receive a US phone number.

Most travel eSIM packages, including XOXO WiFi, focus on mobile data. For a typical 10-day trip, this is usually enough because you can make calls and send messages using internet-based apps such as WhatsApp, Messenger, or FaceTime. At the same time, you can keep your Polish SIM card in your phone and retain your existing number.

Some eSIM providers do, however, offer plans that include a US phone number as well as traditional calls and SMS. This option may be useful if you need a local number for:

• contacting a hotel, apartment, or host,
• booking local services,
• contacting companies operating in the USA,
• receiving traditional calls and SMS messages,
• using services that require a US phone number,
• certain forms of two-factor authentication.

However, it is important to remember that not every phone number provided with an eSIM will be accepted by every verification system. If you need a local number for a specific service, check its requirements before purchasing a plan.

For most tourists visiting the USA for 10 days, a local number is not essential. If your main priorities are navigation, apps, ride-hailing services, messaging, and general internet access while traveling, a data-only package will usually be the simpler option.

Does an eSIM for the USA include a US phone number and calls?

Most travel eSIM plans, including XOXO WiFi, are primarily designed for mobile data and do not include a US phone number for traditional calls and SMS. For communication, you can use internet-based apps such as WhatsApp, Messenger, or FaceTime.

Some eSIM providers do offer packages that include a local phone number as well as traditional calls and SMS. A US number can be useful for booking local services, contacting hotels or businesses in the USA, and in certain cases for two-factor authentication.

If you specifically need a local number, check whether your chosen offer includes voice + SMS, because the phrase “eSIM for the USA” alone does not mean that a phone number is included.

FAQ – eSIM for the USA for 10 days

How much mobile data do I need in the USA for 10 days?

For basic use of Google Maps, messaging apps, and web searches, around 3 GB may be enough. For the average tourist, 5 GB is a safer choice, while intensive social media use, hotspot sharing, or heavier online activity may require at least 10 GB.

When does the XOXO eSIM package for the USA activate?

The package activates automatically after the first connection to a supported network in the destination country. This means you can install the eSIM profile before departure.

Does data roaming need to be enabled?

Yes. For the XOXO eSIM to connect correctly to a partner network in the USA, data roaming should be enabled for the eSIM profile.

Can I keep my Polish SIM card in my phone?

Yes. Phones that support Dual SIM allow you to keep your primary SIM card while using an eSIM for mobile data. However, make sure mobile data is assigned to the eSIM and that automatic mobile data switching is disabled.

Can I make regular phone calls with XOXO WiFi eSIM?

Travel eSIM packages are primarily designed for mobile data. You can make calls and send messages using internet-based apps such as WhatsApp, Messenger, or FaceTime while keeping your primary SIM card active in your phone.

Can I top up my eSIM while staying in the USA?

Top-ups are available for most XOXO eSIM packages. Check the detailed conditions of your chosen plan before purchase. If you expect higher data usage, you can also choose a larger package from the start.

Summary – which eSIM should you choose for a 10-day trip to the USA?

For a 10-day trip to the USA, you do not necessarily need a huge mobile data package. The most important thing is to match the number of GB to the way you use your phone.

3 GB for PLN 37 is suitable for maps, messaging apps, and basic web searches. 5 GB for PLN 45 is the most versatile option for a typical tourist because it provides more flexibility for only a slightly higher price. 10 GB for PLN 75 is worth considering if you frequently use social media, are planning a road trip, spend more time online, or occasionally use a hotspot. The 50 GB plan for PLN 235 is mainly intended for travelers who use large amounts of data or work remotely.

The biggest advantage of eSIM is convenience: you can buy and install it before departure, and after arriving in the USA, you only need to select it for mobile data and enable data roaming.

If you want to have internet access in the USA from the moment you arrive, check the current XOXO eSIM packages and choose the amount of data that best matches your travel plans.
