A SIM card, without the card

An eSIM is the digital version of a SIM card. It lets you add a travel data plan to a compatible phone without inserting or swapping a physical card. You get mobile internet for your trip, while your existing SIM can stay in place.

Most modern smartphones support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many more. Your phone also needs to be carrier-unlocked. If you're unsure, check your phone's settings for an option like "Add eSIM" or "Add Mobile Plan". If it's there, you're good to go.

An eSIM is a digital SIM built into your phone. No plastic card, no swapping. You tap an installation link, follow a few steps, and you're connected to a local network. It works just like a regular SIM, except there's nothing to carry or install physically.

Your plan activates the moment you first connect to a mobile network at your destination, not when you purchase. You have up to 180 days to activate, so you can buy well before your trip and activate when you land.

Yes! You can top up in seconds through your personal dashboard, the same secure link we email you after purchase. No need to buy a new eSIM or create an account. Just pick a top-up plan, pay, and your data is extended instantly.

After checkout, you'll receive an email with an installation link and clear step-by-step instructions within 5 minutes. Tap the link on your phone and follow the prompts. The whole process takes about 2 minutes. We also have a detailed installation guide if you need extra help.

Absolutely. Your eSIM runs alongside your existing SIM. You'll use the eSIM for data and keep your regular number for calls and texts. Most phones let you choose which line to use for what, so you stay reachable on your normal number while browsing on local data.

Our support team is available 24/7. You can reach us anytime at support@travelsimasia.com. We typically respond within minutes, and we'll walk you through any issues, whether it's installation, activation, or anything else.
