When couples or friends travel together, it’s common to look for ways to save on mobile data. One question often comes up: “Can two travelers use the same eSIM?”
The short answer is no – one eSIM cannot be used by two different travelers on two separate devices. However, there are practical alternatives that can help you stay connected without breaking the bank. This guide explains why eSIM sharing doesn’t work and what options are actually available for traveling pairs or groups.

No, one eSIM cannot be used by two travelers on separate devices. Each eSIM is designed to work on only one device at a time. Once an eSIM profile is installed and activated on your phone, it becomes locked to that specific device and cannot be transferred or shared with another person’s phone.
Even if you try to scan the same eSIM QR code on a second device, it usually either fails or deactivates the first phone’s connection. So for technical and security reasons, eSIMs cannot function across multiple devices at the same time.
There are a few key reasons why you can’t share an eSIM with someone else:
In simple terms, eSIMs are built to serve one traveler per plan, ensuring security and reliability across international networks.
If two or more travelers want to stay online, there are smarter ways than trying to share one eSIM.
This is the most reliable solution.
Each person activates their own eSIM plan on their phone. Many eSIM providers offer similar plans at competitive prices, making this option more affordable than you might think. You can buy separate eSIMs from Gigago for different destinations or even choose plans from the same provider to enjoy similar coverage.
One traveler can turn on mobile hotspot or tethering to share their data connection with others nearby.

Consider buying one larger eSIM plan for the traveler who uses more data (for navigation, social media, or work) and a smaller, cheaper plan for the other person who mainly needs connectivity for messaging and emergencies. This balanced approach can save money while ensuring both people have independent access when needed.
Some eSIM providers offer discounts when you purchase multiple eSIMs at once. Check if your eSIM service has bundle deals, group discounts, or promotional offers for buying two or more plans together.
When traveling as a pair or in a group, buying two eSIMs might seem like an extra expense – but it’s usually worth it when you compare the real costs and benefits.
| Option | Details | Estimated Cost | Pros | Cons |
| Option 1: Two separate Japan eSIMs (1GB/day each) | Each traveler activates their own Gigago Japan eSIM with 1GB/day high-speed data. | $15 total ($1.5 per day per person) | – Independent access for both travelers – Fast, stable network for each phone – Freedom to explore separately | Slightly higher upfront cost |
| Option 2: One Large eSIM (10GB shared via hotspot) | One traveler activates a 10GB plan and shares data through mobile hotspot. | $14.5 total, but potential extra costs | – Slightly cheaper upfront – Simple setup on one device | – Faster battery drain – Limited mobility — must stay close – Slower speeds for the second device – Risk of running out of data quickly |
| Hidden Cost | Description | Extra Expense / Drawback |
| Emergency Top-ups | Extra 5GB top-up when data runs out faster than expected. | $10–$25 per top-up |
| Battery Use | Hotspot drains the main phone’s battery up to twice as fast. | Requires power bank ($20) or frequent charging stops |
| Lost Flexibility | Can’t separate for different activities without losing connection. | Limits travel freedom |
To sum up, while sharing one eSIM may seem cheaper at first, the real-world costs — both financial and practical — make buying two eSIMs the smarter option. For a trip to Japan, the difference is roughly the price of one coffee a day, but the convenience and independence are worth much more.
If you’re planning a trip with a companion, consider your travel style. Will you stay together constantly, or do you value the flexibility to split up? Do you both need regular internet access, or will one person use data minimally? Your answers will guide you to the right solution.
