How to Stay Connected While Traveling: eSIM, Roaming, Portable WiFi or Local SIM Card?

Share on social networks:

Travel takes us to amazing places – sometimes literally in the middle of nowhere – but these days, being offline is less of an exotic perk and more of a source of stress. Whether it’s an urgent e-mail, the perfect sunset for Instagram, or simply trying to find your way using Google Maps, internet access often becomes essential.

Luckily, there are several ways to stay connected while abroad: roaming, eSIM, portable WiFi devices, or local SIM cards. Each option has its pros and limitations – here’s a brief overview to help you choose the best solution for different travel scenarios.

🌍 1.Roaming – Convenient, but Check the Fine Print

Roaming allows the use of your domestic mobile plan while abroad – no need to change SIM cards or adjust phone settings. Within the EU, this is often very budget-friendly thanks to the “Roam Like at Home” rule, which treats calls, messages, and data usage the same as back home.

Outside the EU, however, things can get complicated quickly. Service charges in the US, Asia or Africa can be surprisingly high – sometimes a FaceTime call ends up being the most expensive “dinner” of the trip. It’s worth checking your operator’s roaming options in advance – many offer daily or weekly packages that can ease the blow to your travel budget.

💡 Business tip:

For frequent business travel, it’s worth considering mobile plans with international roaming included – many corporate options already cover this.

📱 2.eSIM – A Digital SIM for Those on the Move

eSIM is a virtual SIM card that can be activated by scanning a QR code, through an app, or a website. It’s a great option for those who want to keep their current number while using a local data plan – all without physically swapping cards.

The ability to use multiple numbers and the flexibility of switching between destinations make eSIM especially convenient. However, it’s important to check in advance whether your device supports eSIM technology and if it’s available in the country you’re visiting.

🧳 Travel tip:

Platforms like Airalo, Holafly, and GigSky offer eSIM packages for nearly every country, often cheaper than standard roaming.

📶 3.Portable WiFi Devices – Pocket Internet for Multiple Devices

For those who just need internet access (without calls or texts), portable WiFi – also known as MiFi – can be a practical solution. These small devices share an internet connection across multiple gadgets, making them ideal for couples, families, or anyone carrying several devices.

These devices can be purchased or rented, and are widely available at airports and through online services. They’re particularly cost-effective for longer trips or group travel.

⚠️ Note:

In more remote areas, signal strength can be weak – a great excuse for a digital detox (even if the device stays on).

📶 4.Local SIM Card – Budget-Friendly and Efficient

For longer stays and high data usage at a good price, a local SIM card remains one of the most practical choices. It’s usually available at airports, shops, or kiosks, often offering large data packages at very reasonable rates.

An unlocked phone is required, and in some countries, a passport may be needed when purchasing the SIM. While frequent switching between countries can make swapping cards a bit tedious, this option is ideal for extended stays in one place.

📍 Especially useful for digital nomads, students, or anyone staying longer than a week.

📴 When None of the Above Works – Welcome to the "Signal Wilderness"

Technology is great – until it stops working. For example, in Namibia, signals can be found near main roads, but once you head deeper into nature, all options go out the window.
In such cases, the best thing to do is simply to embrace the situation. Silence, nature, no pings or notifications – that’s luxury. Just make sure Google Maps is downloaded for offline use. Getting lost without signal and orientation isn’t exactly charming.

So, Which Option Is Best?

There’s no one-size-fits-all answer – it all depends on the destination, length of stay, travel style, and specific needs (internet access, calls, multiple devices…).
With a little planning and the right information, there’s no need for that panicked roaming activation at the airport. From now on, staying connected can be smart, efficient, and not the most expensive souvenir of the trip.
