- Airport transfers & navigation
- Translation apps

Adding Japan, Vietnam or another Asian destination? A multi country esim may be simpler, so you can keep one travel data setup as your journey continues.
Hanoi: a fast-rising favourite
Hanoi brings together atmospheric old streets, lakeside walks, incredible food & easy access to wider northern Vietnam.
A Vietnam eSIM can help you stay connected while moving between airport transfers, hotels, cafés, day trips & local attractions. No searching for a physical SIM after landing... no worrying about expensive home-plan roaming... just prepaid data for your trip.
For Southeast Asia routes, check the Asia Southeast 7 eSIM, which is listed for Vietnam, Singapore, Malaysia, Indonesia, Thailand, Cambodia & the Philippines.
Planning a wider route? The Asia 20 eSIM lists Vietnam, South Korea, Japan, China mainland, Thailand, Singapore, Australia & other destinations in one regional plan.
One Asia trip, one simple connectivity plan
Imagine this:
Maya is travelling from New York to Seoul, then Hanoi, with a few days in Tokyo before flying home.
Instead of arranging separate connectivity for every stop, she chooses a regional international eSIM that covers her route.
Her travel hack:
- She checks that her phone is unlocked & eSIM compatible.
- She purchases a suitable Asia plan.
- She installs the QR code before flying.
- She keeps her home SIM active for banking texts and 2FA.
- She turns off home SIM data roaming.
- She selects the travel eSIM for mobile data after landing.
- She monitors usage & tops up if needed.
That’s the beauty of a prepaid esim... one digital profile, no physical SIM swapping & no contract!
Fall 2026 data habits: travellers are buying smarter
The biggest connectivity trend isn’t simply travelling more. It’s planning better!
Recent industry data suggests that the median travel eSIM purchase is around 3GB, while approximately 63% of travellers buy 5GB or less. For many ordinary holiday trips, a practical planning guide is roughly 1GB per day.
That can cover everyday essentials such as:
- Google Maps and navigation
- Messaging
- Ride-hailing apps
- Light social media
- Travel bookings
- Occasional video calls
A recent traveller data usage study also suggests that many people use less data than expected... although heavy streaming, hotspotting and remote work can change everything!
How much data might you need?
Use this as a helpful starting point:
- Short city break: 1GB–3GB
- One week of regular sightseeing: 3GB–5GB
- Two weeks with daily navigation and social media: 5GB–10GB
- Digital nomad or business travel: 10GB+, depending on video calls, cloud work & hotspot use
- Frequent streaming or laptop hotspot: choose a larger plan or check top-up options
These are planning estimates, not guarantees. Your usage depends on your apps, phone settings, video habits & whether you use Wi-Fi.
The Asia 20 plan is listed with options including 1GB, 3GB, 5GB, 10GB, 20GB & 50GB plans, with different validity periods. Always check the live product page for the latest plan details before buying.
Why digital nomads are choosing eSIM more often
Digital nomads need flexibility... but they also need their home number.
An eSIM lets many travellers use a travel data plan while keeping their regular SIM available for important SMS messages, banking alerts & two-factor authentication. That means:
- Home SIM stays available for identity checks
- Travel eSIM handles mobile internet
- No need to remove a physical SIM
- Easier switching between data lines
- Top-ups can be added when required
This setup is especially useful for remote workers, freelancers & business travellers moving through several countries.
Just remember: myesims.com data eSIMs provide mobile internet data. Voice calls and SMS are not included as standard, although you can continue using internet-based apps such as WhatsApp, Zoom, Teams, Skype & other data services.
Practical eSIM data saving tips for fall 2026
Want your plan to last longer? Try these simple habits!
1. Install before flying
Install your eSIM while you still have reliable Wi-Fi. You can then arrive ready to connect instead of trying to scan a QR code at the airport.
Check the validity rules first... some plans begin when they first connect to a supported network, while installation deadlines may apply.
2. Disable home SIM data roaming
Keep your home SIM available for calls or banking SMS if needed, but turn data roaming off on that line.
Then select your travel eSIM as the default mobile data line.
Important: your travel eSIM may require Data Roaming to be switched on. Follow the instructions in your activation email and myesims.com FAQs.
3. Use Wi-Fi for big downloads
Download films, podcasts, maps and large files before leaving your hotel or café Wi-Fi.
Streaming video and automatic app updates can use data quickly... especially when travelling with family!
4. Monitor your usage
Check your phone’s cellular data settings regularly. Some plans may also include a usage link in the eSIM email.
A quick daily check can help you spot an app using more data than expected.
5. Turn off background refresh
Restrict background data for apps you don’t need while travelling. Cloud photo backups, social media refreshes and automatic updates can quietly use your allowance.
6. Top up before you run low
Don’t wait until your data reaches zero. If your plan supports top-ups, add more while you still have a connection.
Travelling with family? You can also explore options for topping up data eSIMs for your loved ones.
