Introduction to Using eSIMs for International Events
What is an eSIM and How Does It Work?
An eSIM (embedded SIM) is a digital SIM profile that lives on your phone instead of a physical card. For event travel, a travel eSIM provides data-only access to local mobile networks so you can use maps, ticketing apps, messaging, and mobile wallets without swapping SIM cards. Activation typically involves purchasing a plan, scanning a QR code, and installing the profile in your phone settings.
Why Choose an eSIM for International Events?
Using an eSIM for international events can save time at arrival, reduce the need to hunt for local SIM sellers, and make it easy to switch between plans when you travel to multiple locations during the same trip. Travel eSIMs are especially convenient when you want reliable data for maps, live updates, mobile ticketing, and remote work during busy event days.
Note: travel eSIMs are data-only plans for travel use and are not intended to replace a home mobile carrier. VAYO offers prepaid travel eSIM data for 190+ destinations.

Planning Your eSIM Data Plan for an International Event — eSIM for international events
Checking Device Compatibility and Requirements
Before you buy, confirm your phone supports eSIM and is unlocked for travel use. Compatibility depends on phone model and OS version; check VAYO’s guidance and the latest compatibility list in the FAQ: https://usevayo.com/faq. If you plan to use mobile tethering, verify your device supports that feature with a data-only eSIM.
Choosing the Right Data Plan: Country, Regional, or Global
For event travel, choose a plan type based on your itinerary:
- Country plan: Best when your event is in a single country (e.g., conference in London). These plans focus data on one destination and can be cost-efficient for short stays.
- Regional plan: Good for multi-city events within the same region (e.g., week-long festival tour across several neighboring countries).
- Global plan: Useful when your trip includes several non-adjacent countries or last-minute changes.

When selecting data amounts, estimate usage for maps, streaming (if needed), video calls, and background app updates. For practical tips on avoiding roaming fees and reducing surprises, see: https://usevayo.com/blog/avoid-roaming-fees-esim-vayo
How to Purchase and Activate Your VAYO eSIM
- Browse plans and pick country/regional/global options on the site or app.
- Pay online with card or Apple Pay.
- Receive a confirmation email with your QR code and install instructions.
- Open the QR code on the device you plan to use and follow the phone settings flow to add the eSIM profile.
You can also manage installation and usage through the VAYO iOS app, where you can install the QR, top up data, and contact support.
Best Practices for Staying Connected During International Events
Managing Your Data Usage Efficiently
- Prioritize essential apps (maps, ticketing, communication) and restrict background data for less critical apps.
- Pre-download schedules, maps, and any event materials when on Wi‑Fi.
- Use lightweight versions of streaming or switch to audio-only for calls and sessions when possible.
- Monitor usage in the VAYO iOS app or your phone settings to avoid running out mid-event.
Using Dual SIMs to Keep Your Number and Stay Connected
Most modern phones support dual SIM (physical + eSIM). A VAYO travel eSIM is data-only, so you can keep your primary physical SIM active for calls and SMS while using the eSIM for data. This is useful when you need to receive two-factor authentication (2FA) texts on your main number but want local data for apps.
Steps to use dual SIM effectively:
- Install the VAYO eSIM and label it (e.g., "Travel Data").
- Leave your primary SIM enabled for calls/SMS and set mobile data to the eSIM profile.
- Disable data roaming on your primary SIM to avoid unexpected roaming charges.
Troubleshooting Common Connectivity Issues
If you lose data or experience poor connectivity at an event:
- Toggle Airplane Mode on/off.
- Reboot your phone.
- Confirm the eSIM profile is active in Settings and that mobile data is set to the eSIM.
- Check APN settings only if instructed by support (most VAYO profiles configure automatically).
- Move to a different area of the venue or step outside—large crowds and indoor venues can affect signal.
If issues persist, consult VAYO Help: https://usevayo.com/help or the FAQ: https://usevayo.com/faq for device-specific guidance and support options.
Note: Local network coverage and speeds vary by location and device; check local conditions and plan accordingly.
Comparing eSIMs to Traditional Roaming for Event Travel
Challenges of Carrier Roaming During International Events
Carrier roaming can be convenient but may bring higher charges or require purchasing an international pass from your home carrier. During major events, visiting networks may be congested and roaming prices can add up quickly if data usage isn't monitored.
Advantages of Prepaid Travel eSIMs Like VAYO
Prepaid travel eSIMs let you buy a set amount of data for a destination or region, making costs predictable. With a VAYO travel eSIM you can:
- Activate data before you land so you're connected immediately.
- Use local network access through a prepaid plan rather than relying on roaming rates.
- Manage usage and top up via the VAYO iOS app.

When to Consider Carrier Roaming or Other Options
Carrier roaming or local physical SIMs may be worthwhile if you need voice and native number service and can't use dual SIM setups, or if your carrier offers a temporary low-cost roaming package for the exact destination and dates. Balance convenience, expected data needs, and cost when deciding.
Additional Tips and Resources for a Smooth eSIM Experience
Using the VAYO iOS App to Manage Your Plan
The VAYO iOS app lets you install the QR code, track data usage, top up plans, and contact support. If you want on-device management, download the app and follow the in-app install flow. Download on the App Store for iPhone users.
Preparing for Event-Specific Connectivity Needs
- Pre-register accounts and download event apps or e-tickets on Wi‑Fi.
- If you're presenting or working remotely, consider a higher-data plan or portable hotspot options.
- For multi-city events, plan whether a regional or global plan makes sense to avoid switching plans frequently.
