Essential Tips for Using an eSIM Mainland China During Your Trip to China
Share
Last year, when I traveled solo to Xi’an and Beijing, one of my biggest concerns was: How am I going to stay connected once I land in China?
I tried international roaming before — too expensive and often unstable. Local SIM cards were another option, but they required real-name registration and long queues at the airport.
Eventually, I discovered that using an eSIM Mainland China from Chillaxsim solved all my problems — and more.
Today, I want to share the practical tips and tricks I’ve learned during my travels, so you can stay connected without stress and enjoy your journey with confidence.
Tip 1: Install Your eSIM Before You Even Board the Plane
Many travelers don’t realize that you can install your eSIM Mainland China even before departure!
This means as soon as you land, you’ll already have internet access — perfect for checking maps, booking rides, or confirming hotel details.
Here’s what I did:
- Three days before my trip, I ordered the plan on the eSIM Mainland China product page .
- Minutes later, I received an email with a QR code.
- Scanned it and activated the plan under Settings > Cellular.
- Checked if my phone was compatible by visiting the device compatibility list .
The entire process took less than 10 minutes — no need to swap physical SIM cards, and no risk of losing them.
Tip 2: Use Dual SIM Mode — Keep Your Original Number Active
A lot of people worry that using an eSIM will disable their original phone number — but that’s not true!
Whether you use an iPhone or Android, you can keep both your primary line and the eSIM Mainland China active at the same time. Just switch between them easily in your settings.
On my iPhone XR, I simply went into “Settings > Cellular” and chose which SIM to use for calls and data — super intuitive and hassle-free.
Tip 3: WeChat, Didi, Meituan — All Work Perfectly
Some travelers worry that they won’t be able to use local apps like WeChat, Didi, or Meituan — but rest assured, they work perfectly with the eSIM Mainland China from Chillaxsim.
Even better? I could also access global platforms like Facebook, Google, and Instagram — no extra tools or “special apps” needed. This made sharing travel moments much easier!
Tip 4: Signal Still Works in Rural Areas (Mostly)
You might think only big cities have good signal coverage — but during my trip near the Great Wall, I still had basic connectivity.
While speeds weren’t always full strength, I could still send messages, upload photos, and check location-based services without major issues.
Of course, deep in remote areas, signal may drop — but unless you’re heading far off-grid, you should expect stable connection most of the time.
Tip 5: What to Do If You Lose Connection
Although the eSIM performed well overall, there were occasional hiccups — like sudden disconnections or slow loading.
Here are some quick troubleshooting steps I recommend:
- Restart your phone – Sometimes a simple reboot fixes temporary glitches.
- Toggle Airplane Mode – Turn it off and on again to help reconnect to the network.
- Check eSIM status – Go to Settings > Cellular > eSIM Status for any error messages.
- Contact support – If nothing works, reach out to Chillaxsim’s customer support via the official contact page . Their team is fast and helpful.
What If I’m Also Visiting Hong Kong or Macau?
If your travel plans include more than just Mainland China, you should check out the China, Hong Kong & Macau eSIM plan . This package covers all three regions, so you won’t have to switch SIMs or risk losing connection when crossing borders.
A friend of mine tested this plan during a multi-city trip from Guangzhou to Macau, and he said the connectivity was smooth throughout — perfect for posting travel updates on social media without interruption.
