Roaming in the United States: 2026 Prices and Alternatives

You land at JFK airport. You turn off airplane mode. Your home carrier connects to a local US network. Two minutes later, an SMS arrives. You just spent €50 on background app refreshes.

Using a French mobile plan outside Europe is a financial trap. Standard data rates are exorbitant. Add-on travel packs offer very little data for a high price. You need a better way to stay connected.

GoMoWorld fixes this. You get 15GB of 4G data for €10.99. No hidden fees. No surprise bills. Let us look at the exact carrier roaming fees in the United States and how you can avoid them entirely.

Price of Carrier Roaming in the United States

Your standard carrier plan covers Europe and French overseas territories. The United States falls into a different billing zone. Without a specific add-on, you pay standard out-of-plan rates.

These pay-as-you-go rates are aggressive. French carriers typically charge between €13 and €16 per single megabyte of data in North America. To put that in perspective, opening a single high-resolution photo on Instagram uses about 2MB. That is €30 gone in one second.

To prevent bill shock, carriers offer specific travel packs. The most common is a USA/Canada/Mexico travel pack. It costs €30. It lasts for 30 days. But the data allowance is incredibly small. Some older versions of this pack offered a measly 200MB. Even updated versions rarely provide enough data for a modern smartphone user.

You can also buy a €5 international option. This lowers the per-minute cost of phone calls. It does not give you cheap data. If you use Google Maps or WhatsApp on 4G, you still pay full price.

What It Really Costs for a Trip

Let us ground this in a real scenario. You plan a 15-day road trip in California. You need data every single day.

You need Google Maps to drive from Los Angeles to San Francisco. You need Spotify for the Pacific Coast Highway. You need to check hotel reservations. You need WhatsApp to text your family.

A modern smartphone uses about 1GB of data per day with moderate use. Over 15 days, you need 15GB.

If you rely on the €30 carrier travel pack, you will run out of data on day one. Once the pack is empty, your data is blocked, or worse, you start paying out-of-plan rates. You cannot buy the €30 pack 15 times.

If you do nothing and leave data roaming on, your phone will generate hundreds of euros in charges before the carrier blocks your line. This happens fast. Background apps download emails, sync photos, and update software without you touching the screen.

This problem is not unique to one carrier. Other French operators charge similar premiums. You can see this clearly when looking at carrier roaming in the United States or budget carrier roaming in the United States.

You need a solution designed for high data consumption at a low fixed price.

Comparison Table: Carriers vs GoMoWorld in the United States

Numbers do not lie. Here is exactly what you get for your money when traveling to the US.

For the price of a single coffee in New York, GoMoWorld gives you 4GB of data. For a third of the price of the carrier pack, you get 15GB. The value proposition is clear.

Alternatives to Carrier Roaming in the United States

You have four options to get internet in the US. Three of them come with major drawbacks. One solves the problem completely.

1. The GoMoWorld eSIM (The Smart Choice)

GoMoWorld provides a data-only eSIM tailored for the United States. It runs on local 4G and 5G networks. You get high-speed internet without the roaming markup.

Here is why it works better than carrier packs:

• No Overage: GoMoWorld uses a prepay system. You buy 15GB. You get 15GB. You cannot spend a single cent more by accident.
• App Installation: Everything happens inside the GoMoWorld app. There is no QR code to scan. You do not need a second screen to set it up.
• Manual Activation: You control when the plan starts. You buy the plan today in France. It never expires while waiting. You tap "Start" in the app only after your plane lands in the US.
• Keep Your Number: GoMoWorld is data-only. No calls. No SMS. Your home SIM stays active for receiving important texts, like bank authentication codes.
• Hotspot Included: You can share your 50GB plan with your family. Turn on your hotspot and connect their devices at no extra cost.

To fix your connectivity upfront, get your eSIM United States → now.

2. Buying a Local US SIM Card

You can buy a physical SIM card from AT&T or T-Mobile at the airport. This gives you local data.

The downside? It is expensive and inconvenient. Tourist SIM cards at US airports often start at $40 or $50. You also have to physically remove your home SIM card. If your bank sends a security SMS to verify a credit card payment, you will not receive it.

3. Relying on Public Wi-Fi

You can turn off mobile data entirely and hunt for Wi-Fi. Starbucks, McDonald's, and your hotel will have free networks.

This fails when you actually need connectivity. You cannot order an Uber from the sidewalk. You cannot use Google Maps on the highway. Public networks are also unencrypted, putting your personal data at risk.

4. Comparing Other French Carriers

Maybe you are considering switching carriers before your trip. The reality is that traditional roaming is expensive across the board. The pricing models are identical whether you go to North America or South America. You can verify this by checking roaming costs in Argentina or roaming costs in Brazil. The only real bypass is using a dedicated travel eSIM.

How to set up GoMoWorld for the US

The process takes two minutes. Do this before you leave for the airport.

1. Download the GoMoWorld app (iOS or Android).
2. Create an account.
3. Select the United States.
4. Choose your plan (e.g., 50GB for €19.99).
5. Follow the on-screen prompts to install the eSIM directly via the app.
6. When you land in the US, open the app and tap "Start".

Your data connects immediately. You are ready to navigate, book, and browse.

FAQ

Which countries are included in my carrier plan?

Your standard plan covers European Union countries and French overseas departments (DOM). This includes Germany, Spain, Italy, and Portugal. The United States is not included. Using data there triggers heavy out-of-plan charges immediately.

How do I activate my voicemail abroad?

If your voicemail does not trigger automatically, dial 123. If the local US network blocks this shortcode, dial +33 6 12 000 123. You will need your secret PIN code to access your messages. Note that calling your voicemail from the US will incur roaming voice charges.

How do I get internet in the US?

You can buy a carrier travel pack for €30, which gives you a very small data allowance. Alternatively, you can leave data roaming on and pay per megabyte, which is financially dangerous. The safest and cheapest method is to buy a GoMoWorld eSIM for the US, giving you up to 50GB of data starting at €3.99.
