Internet in 100 countries – eSIM and internet without roaming

Traveling has never been as accessible as it is today. Remote work, digital nomads, spontaneous trips – all of this makes internet in travel an absolute necessity. Access to the network today is not only a convenience, but often a requirement for work, navigation, or staying in touch with loved ones. However, one key question arises: is it possible to have a single service that provides internet abroad in over 100 countries?

Just a few years ago, the answer was: no. Today, the situation looks completely different thanks to solutions such as eSIM, modern mobile internet, and global data packages. The dynamic development of technology has caused the boundaries between telecommunications markets to begin to blur, and the user gains greater freedom of choice. In this article, we will analyze whether it is actually possible to have internet without roaming, how such services work, and whether they are cost-effective.

What is eSIM and how does it change mobile internet abroad?

1. eSIM – a next-generation digital SIM card

eSIM (embedded SIM) is a SIM card built into the device that eliminates the need to physically replace a card. Instead, you install the operator profile digitally – in just a few minutes.

The most important features:

• no physical SIM card
• the ability to use multiple operators at the same time
• fast activation (even before departure)
• an ideal solution for people who travel

2. Which phones support eSIM?

More and more devices use eSIM technology. Most often these are:

• iPhones from model XS, XR and newer (including series 11, 12, 13, 14, 15)
• Samsung Galaxy S20 and newer, as well as selected models from the Fold and Flip series
• Google Pixel from version 3 and above
• selected Huawei, Xiaomi, Oppo models, as well as iPads and smartwatches

However, it is worth remembering that eSIM availability may differ depending on the region and device version, so you should always check the specifications of a specific model.

3. How to install eSIM step by step?

The eSIM installation process is quick and intuitive. It usually looks like this:

• You buy an eSIM package from a selected provider
• You receive a QR code or activation link
• You go to phone settings → mobile network → add eSIM
• You scan the QR code or install the profile manually
• You activate the data package

The whole process usually takes a few minutes and is best done before departure, while having access to Wi-Fi.

4. Why is eSIM the future of internet in travel?

Thanks to eSIM you can:

• have mobile internet abroad without visiting a store
• avoid high roaming costs
• use local rates in many countries
• change data packages depending on your needs

It is eSIM that enables access to the internet in over 100 countries within one service, giving the user full freedom and independence from traditional operators.

How does internet in over 100 countries work?

Global data packages – the key to mobility

eSIM operators offer so-called global data packages that work in many countries at the same time.

Instead of buying a separate plan in each country:

• you activate one package
• you use the internet in different regions
• you do not worry about changing the operator

Roaming technology vs internet without roaming

Traditional roaming:

• high price per MB of data
• speed limitations
• risk of a high bill

Modern eSIM solutions:

• work like a local operator
• offer internet without roaming
• provide predictable costs

Comparison of solutions

The biggest differences

eSIM wins because:

• it works in many countries without changing the card
• it can be activated remotely
• it offers different data packages tailored to travel

Mobile internet in travel – what options do you have?

Choosing the right solution depends on your travel style, length of stay, and data needs. Each option has its advantages and limitations, so it is worth matching it to your needs.

1. eSIM (the most universal solution)

• works globally – one eSIM can provide internet abroad in many countries without changing settings
• quick configuration – activation takes a few minutes and is done entirely online, often even before departure
• no physical cards – you do not need to look for points of sale or replace SIM cards, everything is digital

2. Mobile router (MiFi)

• the ability to connect many devices – an ideal solution for families, teams, or working with a laptop and tablet at the same time
• requires a separate SIM or eSIM – it is necessary to purchase a data package or configure the device before departure
• additional equipment to carry – means the need to charge it, keep track of it, and it takes up space in your luggage

3. Local SIM card

• often cheap – local operators offer attractive prices, especially for longer stays
• requires registration in the country – in many places it is necessary to show ID or complete formalities
• problematic for short trips – purchase and activation may take time, which is inconvenient for short travel

4. Phone hotspot

• convenient, but dependent on the main data package – you use internet from your phone, which can quickly consume available data
• fast data consumption – connected devices (e.g. laptop) use more data than typical mobile use

In practice, more and more people choose eSIM because it combines convenience with global coverage and eliminates the need to organize internet on site. On the other hand, a mobile router or local SIM card may be a better choice in specific situations, e.g. for longer stays or traveling in a larger group.

Example solution – eSIM from XOXO WiFi

There are already specific services on the market that implement the idea of global internet in practice. One example is the XOXO WiFi offer, which provides access to mobile internet in up to 108 countries within one eSIM solution.

What distinguishes this offer?

• wide coverage covering most popular travel destinations
• affordable data package prices compared to traditional roaming
• fast activation and no need for a physical SIM card

Additionally, users can choose from different package variants tailored to their travel style. In addition to global plans, there are also:

• World 70 and World 84 packages (covering selected groups of countries)
• regional packages such as Europe or Asia
• single-country packages from around the world
• flexible options tailored to short and long trips

Thanks to this, you can choose a solution perfectly suited to your route, instead of overpaying for coverage you will not use. This shows that internet in over 100 countries is no longer just a concept, but a real service available to every traveler.

What to pay attention to when choosing internet abroad?

Choosing the right service is not only a matter of price, but above all matching the offer to your travel style and real needs.

Before choosing a service, check:

✔️ Coverage
does it work in the countries you visit – make sure the operator covers all points of your trip
does it include regions (e.g. Europe, Asia) – regional packages are often more cost-effective

✔️ Data package
how many GB you get – match the package size to your needs
whether there are speed limits

✔️ Validity period
7 days, 15 days, 30 days – choose according to your stay
whether it can be extended

✔️ Internet speed
LTE / 5G – check available technologies
possible limits after exceeding the package

✔️ Price
cost per GB
no hidden roaming fees

Can one internet service really be enough?

When yes

• you have a stable connection – LTE or 5G access

This solution is especially appreciated by:

• digital nomads
• business travelers
• frequent flyers

In practice, this means that internet without roaming stops being a marketing slogan and becomes a real standard.

FAQ – frequently asked questions (FULL VERSION, NOT SHORTENED)

How do I activate an eSIM?
Activation usually involves scanning a QR code or downloading the operator profile in the phone settings, which takes only a few minutes and does not require visiting a store.

Can I top up an eSIM data package during travel?
Yes – most operators allow quick purchase or extension of the data package online, without interrupting mobile internet usage.

Does eSIM work without internet during first installation?
