What is an eSIM?
An eSIM (embedded SIM) is a small chip built directly into your smartphone, tablet, or smartwatch. Unlike a traditional physical SIM card that you insert and remove from a tray, an eSIM is permanently soldered onto the device's motherboard. It stores your mobile plan information digitally, which means you can activate a cellular plan without ever handling a tiny plastic card.
The technology behind eSIM has been standardized by the GSMA since 2016, but it has only become mainstream in the last few years as major manufacturers adopted it across their flagship and mid-range devices. Today, most smartphones sold worldwide come with eSIM support built in.
How Does an eSIM Work?
When you purchase an eSIM data plan, you receive a QR code or an activation link via email. Scanning that QR code with your phone's camera downloads a digital profile onto the embedded chip. This profile contains all the information your device needs to connect to a mobile network — just like a physical SIM would.
The key difference is speed and convenience. There is no waiting for a card in the mail, no fiddly SIM trays, and no risk of losing a tiny piece of plastic in an airport. The entire activation process takes under two minutes.
Here is how the process works step by step:
- Choose a plan — Select a destination and data package from an eSIM provider like CheapereSIM.
- Receive your QR code — After purchase, you get an email with a QR code within seconds.
- Scan and install — Open your phone's settings, go to the eSIM section, and scan the QR code.
- Activate at your destination — The eSIM installs immediately but only starts using data when you connect to a network abroad.
You can install your eSIM days before your trip. It sits dormant until you arrive and connect, so there is no wasted data.

Benefits of eSIM for Travelers
For anyone crossing borders, eSIM technology solves the biggest pain point of international travel: staying connected affordably. Here is why millions of travelers have switched:
- Instant activation — Buy before your flight and activate the moment you land. No queuing at airport kiosks.
- No roaming charges — Use a local data plan at local prices instead of paying your carrier's extortionate roaming rates, which can reach $10–15 per megabyte.
- Dual SIM convenience — Keep your home number on the physical SIM for calls and texts while using the eSIM purely for affordable data.
- Multi-country plans — Regional eSIM plans cover entire continents, ideal for multi-stop trips across Europe or Southeast Asia.
- No SIM card to lose — Everything is digital and stored securely on your device. One less thing to worry about.
- Eco-friendly — No plastic card, no packaging, no shipping. A small but real reduction in waste.
How Much Does a Travel eSIM Cost?
Travel eSIM prices vary by destination and data amount. Here are some typical prices from CheapereSIM:
| Destination | Data | Duration | Price |
|---|---|---|---|
| Turkey | 1 GB | 7 days | from $0.64 |
| Japan | 1 GB | 7 days | from $0.98 |
| USA | 1 GB | 7 days | from $1.26 |
| Thailand | 1 GB | 7 days | from $0.98 |
| Italy | 1 GB | 7 days | from $0.80 |
These prices are significantly cheaper than carrier roaming, which typically costs $5–15 per day for a fraction of the data.
Common Questions About eSIM
Can I use eSIM and my regular SIM at the same time?
Yes. Most eSIM-compatible phones support dual SIM, meaning you keep your regular physical SIM for calls and texts while using the eSIM for data. This is the recommended setup for travel.
Do I need WiFi to install an eSIM?
Yes. You need an internet connection (WiFi or mobile data) to download the eSIM profile. That is why we recommend installing the eSIM at home or your hotel before heading out.
Can I reuse an eSIM?
It depends on the provider and plan. Some plans allow top-ups and reactivation, while others are single-use. CheapereSIM plans can be reinstalled if deleted, as long as data remains on the plan.
Does my phone need to be unlocked?
Yes. Your phone must be carrier-unlocked to use a travel eSIM. If your phone is locked, contact your carrier to request an unlock before your trip.
What happens when my eSIM data runs out?
When your data is depleted, you simply stop having mobile data. You will not be charged extra. You can purchase a new plan if you need more data — the process takes just a couple of minutes.
