Mobile Internet for iGaming Conferences: eSIM and SIM Services

Publication date: 3 December 2025

For participants and organizers of iGaming conferences, stable and fast internet is not just a convenience but a critical necessity. Mobile connectivity through eSIM and SIM services is an excellent solution for professional betting and gambling affiliate events where speed, reliability, and mobility are crucial to success. In this case, virtual international SIM cards and corresponding SIM services provide the optimal balance between convenience and efficiency.​

Internet at iGaming Conferences: How to Avoid Connectivity Issues

At large-scale iGaming conferences, networks often become overloaded as thousands of attendees connect simultaneously to the same Wi-Fi, resulting in reduced speeds and unstable connections. 

Connecting to the local mobile internet is one of the most common and frustrating problems for travelers. Difficulties with cellular connection and network access in different countries arise due to a combination of technical, legal, commercial, and sometimes even cultural reasons: 

• In many countries, strict laws against fraud and terrorism are enforced. To purchase a SIM card, you may need a passport or even a local ID document. Without these, you will simply be denied service, for example, in Turkey, China, Germany, Brazil, or Saudi Arabia.
• Expensive roaming tariffs: telecom operators benefit from your use of your home number while roaming, generating significant revenue. Therefore, they have no interest in making it easy and affordable for tourists to switch to a local operator.
• Not all countries allow purchasing a SIM card at supermarkets or kiosks. Often, you must visit an official operator’s store, which might only operate on weekdays until 6 PM.

Even when connected and paid for, mobile connectivity can suffer due to tower overload and roaming restrictions.

Now imagine arriving in Malta or Barcelona for an iGaming conference, turning on your phone — and that’s it, you’re connected. The internet works immediately, Telegram loads chats, and navigation guides you to the meeting point.

This has been made possible thanks to eSIM services that enable pre-connecting to local internet without leaving home.

How to Solve the Problem: eSIM for Travels and Conferences

1. Research Before Departure: Check which frequencies (LTE bands) your phone supports and what operators are available in your destination country.
2. Or Choose eSIM: eSIM technology drastically simplifies the process. You can buy and activate a virtual SIM card online before departure via apps like Airalo, Nomad, or Holafly. This eliminates the need to search for a communication shop and show your passport.

What is eSIM: An International Card for Travel? 

An eSIM (embedded SIM) is a virtual SIM card that can be activated directly within your smartphone settings. No plastic, no slot swapping, and no trip to a carrier store required.

You choose the country, traffic volume, and validity period, then receive a QR code for activation. Within a few minutes, you’ll have local internet access.

How Does eSIM Work?

1. A built-in chip in your device (smartphone, tablet, smartwatch) is configured programmatically to work with a telecommunications provider.
2. Activation via QR code or app: You scan the operator’s code or install a profile through an online request, and the plan activates within minutes.
3. The ability to store multiple profiles simultaneously (for example, for different countries or providers) with quick switching between them.

Advantages of eSIM for Travelers 

Using eSIM is convenient because it offers several advantages:

1. Quick Activation: It takes only a couple of minutes to activate without searching for physical SIM cards or visiting stores. There’s no need to look for local SIM cards at airports or retail outlets; you can purchase plans online from local operators (e.g., through apps like Airalo, Holafly) before departing.
2. Affordable Purchase and Payment: Local eSIM plans cost less than roaming charges and help save money on internet usage.
3. Convenient Virtual Card Setup: Multiple plans can be stored on a single device, allowing easy switching between them. It’s simple to toggle between your primary number and temporary internet-only rates.
4. Secure Connection of Travel eSIM: Your data and traffic are protected, eliminating the risk of losing a SIM card, and providers ensure encrypted connections.
5. Easy Management: All configurations and plans can be changed directly through the application, eliminating paperwork and visits.

Before traveling, check the list of operators in your destination country that support eSIM and compare tariff prices. For occasional trips, international SIM services are often more cost-effective than roaming.

Before traveling, make sure your phone supports eSIM. Phones compatible with eSIM include models such as iPhones starting from iPhone 12 up to iPhone 17 Pro Max, devices by Xiaomi and Redmi including Poco X7, as well as most Samsung Galaxy smartphones and other Android-based phones.

Advantages of eSIM compared to Physical SIM Cards:

1. Convenience and Flexibility: eSIM doesn’t require physical insertion or replacement — it’s managed remotely through device settings. Operators and tariffs can be easily switched within minutes without visiting a store.
2. Multiprofile Capability: One eSIM can store multiple operator profiles, ideal for those who use separate numbers (e.g., business vs personal) or frequently travel internationally.
3. Time and Space Savings: Eliminating the physical slot frees up internal space, enabling smaller, waterproof, and dust-resistant designs. Tariff activation takes mere minutes.
4. Security: eSIM is harder to lose or counterfeit, secured by modern encryption technologies, enhancing user data security.
5. Global Compatibility and Roaming Savings: Users can connect to local operators worldwide without buying new SIM cards, particularly beneficial for frequent travelers and digital nomads.

Thus, eSIM provides greater convenience, multifunctionality, and flexibility compared to traditional physical SIM cards, making mobile communications simpler and more modern. The main drawback is that not all devices and operators fully support eSIM yet, although compatibility continues to grow.
