Do you know what data roaming is and why it can become a financial nightmare for your company? In fact, a three-day business trip can generate a four-figure international roaming bill once employees submit their expenses.

There have even been extreme cases, such as a man from Florida who received a $143,442.74 T-Mobile bill after a trip to Switzerland. These excessive costs occur because mobile operators typically charge high fees for using another carrier’s network.

International mobility for executives has become a structural component of corporate growth, and connectivity is no longer a complementary service but a direct extension of a company’s technological infrastructure. In this article, we’ll explain what happens if you activate data roaming and, more importantly, the best alternatives to prevent your business trips from becoming a budget disaster. Let’s get started!

What is data roaming and why is it a problem for executives?

Data roaming allows mobile devices to connect to the internet when you are outside the coverage area of your usual mobile operator. It works through agreements between operators in different countries, allowing users to connect to foreign networks. When an executive crosses borders, their phone automatically connects to local networks, enabling them to make calls, send messages, and access the internet.

The problem is that most devices have roaming enabled by default, which creates two simultaneous negative effects. On one hand, many employees avoid using mobile data during international trips due to fear of high fees, directly affecting their productivity. On the other hand, finance departments face unpredictable expenses that complicate budget planning.

In 2026, international roaming remains one of the fastest ways to lose control of corporate travel expenses. Corporate roaming agreements were designed when mobile usage abroad was occasional and limited, but today’s business travelers are heavy mobile users. The biggest challenge is unpredictability: roaming costs fluctuate based on employee behavior, vary by country, and are billed after the trip rather than before.

Best alternatives to data roaming for traveling executives

Fortunately, there are specific solutions that eliminate the financial risks of roaming without compromising connectivity.

✅ eSIM Technology
Digital SIM cards represent the most significant shift for corporate travelers. Unlike physical SIM cards, eSIMs are activated via QR code and allow users to switch between local carriers without additional hardware.

For example:

• GlobalTech reduced communication costs by 40% during the first year after implementing eSIM technology.
• InnovateCorp recorded a 30% increase in productivity, as employees spent less time solving connectivity issues.

Companies can save up to 70% on telecommunications costs compared to traditional roaming, and some providers report savings of up to 90%.

✅ VoIP Services
Internet-based calls eliminate roaming charges completely. Companies can reduce monthly communication costs by up to 50%, and many providers offer unlimited calls to more than 26 international destinations.

✅ Portable MiFi Routers
These devices create private WiFi networks using data SIM cards, allowing up to 10 devices to connect simultaneously. They operate with built-in encryption and security protection.

How to implement an effective connectivity solution for business travel

Corporate data security should be your top priority when implementing any connectivity solution for business travel. The protocols you establish will determine whether your company’s information remains protected or becomes exposed to unnecessary risks.

Avoid public WiFi networks for sensitive operations. Cybercriminals can intercept confidential information in airports, hotels, and cafés through man-in-the-middle attacks. When accessing critical company data, always use a virtual private network (VPN) that fully encrypts your connection.

Corporate VPNs create a secure tunnel between employee devices and the company network, allowing remote access to internal resources from anywhere in the world. Additionally:

• Disable automatic connections to WiFi and Bluetooth when not needed
• Keep all devices updated with the latest security patches

HOLASIM simplifies this implementation with a solution that activates in just two minutes using a QR code. The platform provides coverage in more than 180 destinations with 4G/5G connectivity, transparent pricing with no roaming charges, and flexible plans from 1 to 90 days with unlimited data.
