Telephone and Internet in the USA: The guide to staying connected

Traveling to the United States is an incredible and unforgettable experience. But staying connected can quickly become a headache.
Between the different options for Internet packages and calls, technical problems, potential overrun costs, GPS navigation, photo sharing or e-mail exchange… it’s essential to anticipate this aspect of your trip as much as possible to ensure a reliable connection and avoid unpleasant surprises in the middle of a road trip in the middle of the USA.
We’ve put together a complete guide to all your connection problems during your stay.
5 problems you may encounter when traveling in the USA and how to solve them
1. Phone incompatibility
The USA mainly uses 4G and 5G standards, but beware: not all smartphones are compatible with their frequency bands. Before you leave, check whether your device is unlocked and compatible with US networks by consulting the specifications on the manufacturer’s website or directly with our tool.
2. High costs
Roaming charges can be exorbitant. There are many ways to avoid them, including choosing a prepaid plan adapted to the USA.
3. Limited coverage
In rural areas, the mobile network can be weak or non-existent. It’s not uncommon to see “no service” displayed in remote areas.
Check the U.S. operator to which your phone is connected. For example, in Page, Arizona, the downtown area is covered by T-Mobile. AT&T doesn’t have its own antennas; its network uses domestic data roaming to operate.
Be careful, too, if you use a virtual operator, which may not have a domestic data roaming option.
The easiest way is to check which operators cover your road trip and choose a suitable package.

4. Insecure public WiFi networks
Cyber attacks are rare, but they can be a problem on unsecured networks.
To prevent hacking, use a VPN to protect your data.
5. Difficulties recharging devices
In the USA, electrical outlets are different. As in England, you’ll need an adapter to recharge your phone or computer.
The easiest way to do this is to equip yourself before you leave. Universal formats are easily found on the Internet or in specialist stores. You can also carry an external battery to make sure you don’t run out of GPS in the middle of a large park.

It’s the ideal solution for those who don’t particularly want to call or text.
You can use your applications such as WhatsApp or Messenger, or load your GPS maps.

Anticipation: the key to all Internet problems
The best way to avoid problems is to plan before you go.
Buy a prepaid package
Purchasing a specific package for the United States before you leave will save you a lot of trouble. Several websites offer prepaid SIM cards to order online and receive before your trip.
American issue: Why is it useful?
Getting a local number can come in handy, especially for booking activities or contacting local services. American SIM cards often include unlimited calls within the United States. Ask yourself what you’ll need on site?
Choosing a good after-sales service
In the event of a problem, good customer service can make all the difference. Choose operators or service providers with a good reputation for technical support.
Tips for saving on data
- Download your GPS maps offline via Google Maps or an equivalent application before you set off.
- Plan your days to take advantage of WiFi in public places.
- Use data management applications such as Data Usage or My Data Manager to monitor your consumption.
For a short stay, your French operator’s roaming options or an eSIM may suffice. On the other hand, for a road trip or a long stay, an unlimited American prepaid SIM card or a WiFi hotspot hotspot are more economical and practical solutions.
