How to Avoid Roaming Costs? eSIM While Traveling

Business travel is now a daily reality for many entrepreneurs, managers, and professionals. Along with it comes one key challenge: how to ensure stable internet abroad without generating huge roaming costs? In the era of remote work, video conferencing, and cloud access, lack of internet while traveling is not an option. A reliable connection is now the foundation of effective communication and fulfilling professional responsibilities. Without it, even a short trip can mean downtime and financial losses.

Unfortunately, despite EU regulations, roaming outside Europe (and sometimes even within it) can still be very expensive. That’s why more and more people are turning to alternatives such as eSIM, mobile internet abroad, or LTE/5G routers. In this article, we’ll show how to realistically reduce costs while maintaining full freedom to work. Modern solutions not only help save money but also improve comfort and security when using the internet while traveling.

Why is roaming still expensive?

Roaming in the EU vs outside the EU

Within the European Union, the “Roam Like at Home” rule applies, however:

• it mainly covers calls and SMS
• data packages often have FUP (Fair Use Policy) limits
• outside the EU, prices can increase even dozens of times

Hidden roaming costs

In practice, users are often unaware that:

• data transmission in roaming can cost even dozens of PLN per MB
• background apps generate data usage
• automatic system updates can “consume” the entire data package

👉 That’s why finding a solution that provides internet without roaming is crucial.

Best ways to get affordable internet abroad

1. eSIM – the most convenient solution for business

eSIM is a digital SIM card that you install on your phone without physically replacing a card.

Advantages of eSIM for business travel:

• no need to buy a local SIM
• instant activation (often within minutes)
• ability to use multiple numbers at the same time
• flexible data packages tailored to specific countries

Why does eSIM minimize roaming?

Instead of using your operator’s roaming, eSIM works like local mobile internet abroad, which means:

• lower prices
• no unexpected charges
• more stable connection

eSIM activation

Activating eSIM is much simpler and faster than with a traditional SIM card, making it an ideal solution for travel. The entire process is digital, without the need to insert a physical card or visit a store.

• scan the QR code received from the eSIM provider
• download and install the eSIM profile on your device
• enable eSIM in your phone settings
• set it as the data source
• connect to the network and start using mobile internet abroad

2. Local SIM card

An alternative to eSIM is buying a local SIM card.

Pros:

• often cheap data packages
• good network coverage

Cons:

• requires registration
• phone number changes
• time spent purchasing

👉 Compared to eSIM, this is less convenient—especially for business travel.

3. Mobile router (MiFi)

A mobile router is a device that creates a private Wi-Fi network.

When is it worth it?

• you travel in a group
• you need internet for multiple devices
• you work intensively (e.g., data uploads, VPN)

Disadvantages:

• extra device to carry
• requires power

4. Public Wi-Fi – only as backup

Although free Wi-Fi is tempting, it has serious limitations:

• low speed
• instability

👉 For business travel, it should not be your primary internet source.

👉 In practice, eSIM is usually the best choice for business.

What to consider when choosing mobile internet abroad?

✔️ Coverage and destination country
Check whether the plan includes your destination country (or multiple countries if you travel frequently).

✔️ Data package size
Recommended for business travel:

• light use: 1–3 GB
• standard: 5–10 GB
• intensive: 20 GB+

✔️ Internet speed
Some plans have limitations (e.g., LTE instead of 5G).

✔️ Validity period
Plans may be valid for 7, 15, or 30 days.

✔️ Hotspot support
If you want to share internet with other devices—check this option.

How to reduce data usage while traveling?

Business traveler checklist:

✅ disable automatic app updates
✅ use data-saving mode
✅ download documents offline
✅ limit high-quality streaming
✅ monitor data usage on your phone

Is eSIM and internet without roaming worth it?

Cost example

Roaming (outside the EU):

• 1 GB = even 200–500 PLN

eSIM:

• 5 GB = approx. 50–100 PLN

👉 The difference is huge.

When does the investment pay off?

• even after one trip outside the EU
• during frequent business travel
• with intensive internet use

👉 In practice, mobile internet abroad via eSIM can be several times cheaper.

Internet while traveling and data security

In business, security is essential.

Why is eSIM safer than public Wi-Fi?

• no risk of interception
• encrypted operator connections
• greater control over the network

Additional recommendations:

• use a VPN
• avoid logging into banking on public Wi-Fi
• update your system before traveling

FAQ – frequently asked questions

1. Does eSIM work on every phone?
No. Mainly newer models (iPhone, Samsung, Google Pixel) support it. Always check compatibility before purchase.

2. Does eSIM replace a traditional SIM card?
Not necessarily. You can use both at the same time (e.g., business number + eSIM for data).

3. Does eSIM work without roaming?
Yes—you use local networks, so you avoid roaming costs.

4. How much data do I need for business travel?
Typically:

• 5 GB – basic use
• 10–20 GB – intensive work

5. Can I share internet from eSIM?
Yes, most devices allow hotspot usage.

6. Is public Wi-Fi abroad safe?
Not entirely—public networks are often unsecured, which means a risk of data interception, password theft, or impersonation attacks. For business travel, mobile internet or eSIM is a much safer option, providing encrypted and private connections.

Summary: how to avoid roaming costs?

If you travel for business, traditional roaming is the most expensive option and often generates unpredictable costs—especially outside the EU. Better alternatives include modern solutions such as eSIM, mobile internet abroad, or LTE/5G routers, which provide greater cost control and stable connectivity. The biggest advantage comes from eSIM, combining convenience, savings, and security, allowing you to use the internet while traveling without stress or unexpected bills. Additionally, eSIM can be activated before departure and easily tailored to a specific country, significantly improving work comfort.
