What is an eSIM, and how does it work for global travel?
An eSIM (embedded SIM) is a digital SIM card built into your phone, tablet, or laptop. Instead of swapping a physical card at every border, you download a network profile from a provider, which connects you to a local network in each destination. For global travel, that means one plan can cover dozens or hundreds of countries, so you buy once, install in minutes, and arrive already online.
When you buy a global eSIM plan the provider sends a QR code or an in-app install link. Scanning it loads the profile onto your device, and from then on the eSIM behaves just like a normal SIM for data. You can keep your usual SIM active at the same time, so your home number still works for calls and texts.
Is a global eSIM better than local SIM cards in each country?
For most travellers, yes. Buying a local SIM in every country means finding a shop, dealing with language barriers, and starting over each time you cross a border. A global travel eSIM installs before you fly and stays with you as you move between countries. You keep your home number on your normal SIM for calls and codes, and use the eSIM for data. Roaming on your home plan is usually expensive once you leave your region, so for multi-country trips and rolling travel a global eSIM is the faster and cheaper option.
Global coverage and how it works
Global and regional eSIM plans connect to the strongest available local network in each country you visit, so you get dependable data without changing anything at the border. Ubigi offers both regional and worldwide plans and connects to trusted local operators for fast, steady data, while Holafly covers 200+ destinations on a single unlimited plan. Coverage is strongest in cities and along main routes and can ease off in very remote areas, so it is worth checking each provider's destination list and downloading offline maps before heading off-grid.

How to choose the right global eSIM
A few quick checks make it easy to pick the right plan before you travel:
Check the destination list: Confirm that every country on your route is included in the plan's coverage. Ubigi and Holafly both publish full destination lists.
Check your data needs: For maps, messaging, and browsing a small to mid bundle is usually enough. For video calls, remote work, or streaming, choose a larger plan or an unlimited option.
Match your trip length: A short multi-country trip suits a small bundle or a shorter Holafly day plan, while months of rolling travel are better with a larger Ubigi plan or a longer unlimited plan.
Verify device compatibility: Most recent iPhones, Google Pixels, and Samsung Galaxy phones support eSIM. Check under Settings, then Mobile Network, then Add eSIM.
Customer support and setup help
Both providers offer support to get you online quickly. Ubigi has an in-app help centre and email support, plus clear install guides for iOS and Android. Holafly offers 24/7 multilingual chat support and a simple app. Whichever you choose, install and test the eSIM before you fly so you land already connected.
How to set up your global eSIM
Setting up your global eSIM takes just a few minutes:
1. Check compatibility: Confirm your phone supports eSIM (most recent models do). Ubigi and Holafly both list supported devices on their sites.
2. Choose your plan: Pick a plan that covers your destinations and matches your travel dates.
3. Install the eSIM: After purchase you receive a QR code or in-app link. Scan or tap to load the profile onto your device.
4. Activate on arrival: Turn on your eSIM line and enable data roaming when you land in your first destination. Activation usually starts automatically.
5. Test your connection: Open a map or browser to confirm data is working. If not, restart your phone or toggle airplane mode.
