Planning your trip to the United States and wondering how to stay connected without breaking the bank? You've likely heard about eSIM and SIM card solutions, but how do you choose the one that best suits your needs? You're in the right place. At GoMoWorld, we've reviewed and tested the various offers available on the market to help you make the best decision. In this comparison, we detail eSIM and SIM card plans for the United States in 2025. You'll discover why our GoMoWorld solution clearly stands out from the competition.

Today's travelers primarily seek ease of activation, extensive network coverage, and competitive pricing. Several operators now offer eSIM or SIM card solutions for fast and reliable connectivity during your time in the US. Before diving in, here are a few things to consider when comparing these offers:

• Network Coverage: Ensure your solution covers the entire US territory with access to major networks like AT&T, T-Mobile, or Verizon.
• Data Volume Offered: Depending on the duration and your browsing needs, an unlimited plan or a plan with an adjusted data quota might be suitable.
• Validity Period: Most offers range from 7 to 30 days, with some operators offering renewable options.
• Additional Benefits: Some offers include features like built-in hotspot or even a VPN to bypass geographic restrictions.

Among the tested operators, GoMoWorld stands out for its ease of activation, an efficient French mobile app, and unbeatable prices. We present a detailed comparison below.

At GoMoWorld, we offer flexible plans for travelers wanting quality mobile connectivity in the United States. Here are the flagship offers:

• 25GB for 30 days at €19.99: For heavy internet users who want optimal data speed without interruption.
• 12GB for 15 days at €10.99: An ideal formula for a short stay or for those who mainly use their smartphone for browsing and checking emails.
• 2.5GB for 7 days at €3.99: Perfect for testing the service or for travelers with limited needs (checking emails, occasional browsing).

What makes GoMoWorld strong is our commitment to offering coverage in over 200 destinations worldwide, with connectivity ensured by an average of two local networks per country. Furthermore:

Note: Our activation takes less than 2 minutes via an intuitive mobile app, and we offer 24/7 customer support in French to assist you every step of the way.

Our eSIM plan is aimed at modern travelers who do not want to physically change their SIM card. It allows you to keep your usual number on your physical SIM card while accessing an ultra-fast internet connection via the eSIM.

For many travelers, the choice is between using a local SIM card and opting for an eSIM. Here are some key points to help you understand the difference:

• Ease of Installation: The eSIM is downloaded directly to your smartphone without needing to visit a physical store. This saves you time upon arrival.
• Flexibility: With an eSIM, you can keep your native SIM card for calls and receive international offers without changing your equipment.
• Space Saving and Simplicity: The eSIM eliminates the need to physically handle a chip. Plan management is done directly via an app, allowing you to top up or extend your plan online in a few clicks.

However, it's important to note that eSIM requires a compatible and unlocked smartphone. If your phone dates from before 2019 or doesn't accept multiple profiles, a local SIM card might be an alternative solution.

Warning: For users unfamiliar with this technology, it is recommended to check their device's compatibility before ordering an eSIM. Many online guides are available to help you check this easily from your settings.

To help you quickly check the strengths of each solution, we have created the comparison table below. This table highlights key features: price, data volume, plan duration, and additional benefits. In this comparison, GoMoWorld is presented first because it offers both the best value for money and unparalleled flexibility.

It is essential to note that while Airalo and Ubigi offer very good value and excellent coverage, and Holafly stands out with its unlimited plans, no solution matches the flexibility and ease of use of our GoMoWorld offer. Our plans, tailor-made to meet travelers' needs, offer not only competitive prices but also an optimized user experience.

It can be useful to compare not only the offers from different operators but also to consider the general advantages of an eSIM compared to classic SIM cards:

Pros of eSIMs

• Ease of Activation: Downloadable online, no need to visit a store.
• Centralized Management: Multiple plans can be installed and managed via a single app without physically changing cards.
• Time Saving: Almost instant activation upon arrival.
• Flexibility: Ability to use your eSIM on multiple subscriptions without losing your usual number.

Potential Cons

• Compatibility: Not all smartphones support eSIM technology yet, especially older models.
• Lack of Traditional Voice Calls: Most eSIM plans only offer internet connectivity; calls are made via VoIP.
• App Dependency: Plan management relies on a mobile app, which can be problematic in case of failure or technical difficulties.

Note: For the majority of modern travelers with recent devices, the advantages of eSIMs largely outweigh their few drawbacks.

Activating your eSIM is very simple. Once the plan is purchased, you receive a QR code via email or the app. Then simply:

1. Open your smartphone's settings.
2. Choose "Add eSIM Card".
3. Scan the QR code.
4. Confirm activation and wait a few minutes for the connection to stabilize.

This process, which takes only 2 minutes, secures your connection upon arrival in the United States. Thanks to our app's user-friendly interface, you can track your data consumption in real time.

For travelers who also want to make calls, know that you can use VoIP apps like WhatsApp, FaceTime, or Google Messenger. This allows you to fully utilize your data plan even if it doesn't include traditional voice minutes.

Many travelers who have tested our services confirm the simplicity and effectiveness of our GoMoWorld solution. Here's what they say:

"I tested several solutions to stay connected in the USA. The ease of activation and reliability of GoMoWorld's coverage really won me over. Plus, I saved nearly €10 compared to other offers." – A frequent traveler

"The mobile app is intuitive and the customer service, always available, helped me quickly resolve any questions. For me, GoMoWorld is the benchmark for connectivity in the United States." – A digital nomad

To help you quickly visualize the differences between eSIM offers on the market, we provide a second table that also includes rates, data volumes, and validity periods offered by major operators. Note that in this comparison, GoMoWorld remains the optimal solution.

This table clearly demonstrates that, although several solutions offer attractive prices and good coverage, GoMoWorld stands out for the diversity of its plans, ultra-fast activation, and quality customer service, all at very competitive prices.

When choosing your mobile plan, it's essential to consider several aspects to avoid unpleasant surprises once you arrive. Here are some expert tips from our experience at GoMoWorld:

Tip: Always check your smartphone's compatibility with eSIM technology, especially if you own a model older than 2019. It's important to ensure your phone is unlocked to use any operator.

• Compare Options: Use comparison tables and read user reviews to determine which offer provides the best balance between price, validity, and data volume.
• Pay Attention to Commitments: Most eSIM offers are non-binding. This allows you to easily change or top up your plan based on your evolving needs during your stay.
• Examine Hidden Fees: Some offers may include top-up or overage charges. Ensure the communicated price includes all costs to avoid surprises.

Note: The QR code activation method and management via mobile app are generally very secure and optimized for international use. If in doubt, don't hesitate to contact customer support.

If you're still hesitant between these two technologies, here's a brief reminder of their main differences:

• eSIM:
  • Digital installation: faster and without physical travel.
  • Centralized management of your subscriptions.
  • No need to change cards to switch between different plans.
• Physical SIM Card:
  • Requires purchase in-store or via local distribution.
  • May be preferred by those whose smartphone is not eSIM compatible.

For the vast majority of travelers, the eSIM offers the undeniable advantage of simplicity and speed, thus providing a seamless transition upon landing.
