Hi there. I‘m a local Chinese living in Guangzhou, and over the years I’ve helped dozens of foreign friends, colleagues, and travelers figure out one simple but frustrating problem: how to get reliable internet in China.
I've watched friends land at Baiyun Airport, pop in a SIM card they bought online, and breathe a sigh of relief when Google Maps loads instantly. I've also watched others spend 45 minutes at a China Unicom store, sweating through translation apps, only to realize they forgot to turn on data roaming.
This guide is my honest, practical advice based on what actually works in China in 2026. No fluff. No marketing. Just straight talk from someone who lives here and helps foreigners stay connected every single week.
First, Understand the Two Paths
Before we compare providers, you need to understand your two basic options:
Now let me walk you through each option in detail – from a local‘s perspective.
Option 1: Trip.com esim – The “No VPN, No Hassle” Choice
What It Is
Trip.com Esim is a digital SIM card that routes your internet traffic through Hong Kong. That means you can use Google, Gmail, Instagram, WhatsApp, and Facebook without turning on a VPN. For many foreign travelers, this alone is worth the price.
Why I Recommend This to Short-Term Visitors
I've told every friend visiting for 3–5 days: just get this. Here's why:
It works the moment you land – no hunting for a store, no language barrier, no passport photocopying.
Setup takes 2 minutes – scan a QR code, turn on data roaming, done.
Saves your battery – VPNs drain about 30% of your battery. This eSIM doesn't need one, so your phone lasts all day.
No contract, no commitments – use it for 3 days or 30 days, then it expires.
The Catch (Be Honest With Yourself)
No local phone number – you can’t register for Meituan, Taobao, or most Chinese apps that require SMS verification.
Your phone must support eSIM – not all phones do. Check before you buy

Speed: ~23.8 Mbps download – plenty for maps, social media, video calls.
My Verdict
Perfect for: Tourists staying less than a week, business travelers, or anyone who wants zero hassle and doesn't need a local number.
Not for: People staying over a week, or anyone who wants to use local delivery apps and restaurant discounts.
Option 2: China Unicom Local SIM – The “Real China” Experience
What It Is
This is a physical SIM card you buy from a China Unicom store with your passport. It gives you a real Chinese phone number and connects to China's 5G network at full speed.
Why I Tell Long-Term Visitors to Get This
I lived in Shenzhen for years, and my foreign coworkers all switched to China Unicom within their first week. Here's why:
Insane speed – we're talking 496 Mbps on 5G. That's faster than most home Wi-Fi.
A local number unlocks real life in China – with a Chinese number, you can:
Order food delivery on Meituan for a fraction of Uber Eats prices
Get restaurant discounts and vouchers
Use Didi (China's Uber) without issues
Register for museum tickets, train bookings, and more
Cheapest data – at ~$0.34/GB, it's the best value by far.
No fair-use policy – you get exactly what you pay for.
The Catch (Be Honest With Yourself)
You MUST have a VPN – without one, Google, Gmail, Instagram, WhatsApp, and Facebook are all blocked. I recommend Astrill – This is the most reliable one I've used for many years, but it's a bit pricey.
Language barrier – most store clerks speak basic to zero English. But I'll give you a script below to make it easy.
Takes 15 minutes – not bad, but it's not instant like an eSIM.
Physical SIM only – if your phone doesn't have a SIM tray (some newer phones), this won't work.
How to Buy One (Step-by-Step)
I've done this with at least 10 foreign friends. Here's the exact process:
Find a China Unicom store – they're everywhere. Look for the red logo with “中国联通”.
Bring your passport – this is non-negotiable. They need it to register your number with the government.
Point at the plan you want – they usually have a price chart on the counter. The 69 RMB (~$10 USD) plan for 30GB is the sweet spot.
Say “Wo yao zhe ge” (I want this one) – or just point and nod.
Hand over your passport – they'll scan it and take your photo.
Choose your phone number – they'll give you a list of numbers to pick from. Pick one you can remember!
Pay and leave – they'll install the SIM for you. Walk out with working 5G in 15 minutes.
Pro tip: Don't ask complicated questions. The clerk isn't being rude – they just don't speak much English. Keep it simple and you'll be out fast.

My Verdict
Perfect for: Anyone staying more than a week, digital nomads, students, or people who want to actually live like a local.
Not for: Short-term tourists who don't want to bother with a VPN and don't need a local number.
Option 3: Global Yo – The “Backup for Border Crossings” Choice
What It Is
Global Yo is a cheap eSIM that works in many countries. I recommend it for one specific use case: crossing the border into Hong Kong or Macau.
Why I Suggest This as a Backup
You need data at the Hong Kong border – just to set up an Octopus card on your phone to exit the train station. Global Yo saved you from a major headache there.
It's cheap for 1–3 days – $3.89 for 1GB/3 days is hard to beat.
Works as a safety net – if your main SIM fails upon arrival, this gets you online immediately.
The Catch
Terrible speed in mainland China – 0.24 Mbps download. Basically unusable.
Expensive per GB – ~$1.00/GB compared to $0.34/GB for local SIMs.
My Verdict
Perfect for: A 1-day backup when crossing into Hong Kong/Macau, or a safety net for your first hour in China.
Not for: Your primary data source in mainland China. It's just too slow.
You need a local number for apps like Meituan, Didi, Taobao
You're okay with setting up a VPN
You want the cheapest data available
Keep Global Yo as a Backup if:
You're crossing into Hong Kong or Macau
You want a safety net for your first hour in China
Frequently Asked Questions
Q: Do I need a Chinese phone number as a tourist?
A: For a short trip (under a week), no. You can use Didi with an international number, and most hotels work fine. For longer stays, yes – it unlocks local apps and makes life much easier.
Q: Can I use the Trip.com eSIM for AI tools like ChatGPT?
A: No. ChatGPT and Gemini are still blocked on eSIMs because they detect your roaming location. You'll need a VPN for AI tools.
Q: How do I check if my phone supports eSIM?
A: Dial *#06# on your phone. If you see an EID number, your phone supports eSIM. If not, you need a physical SIM.
Q: Is it safe to use a VPN in China?
A: Yes, for personal use. Millions of foreigners and locals use VPNs daily. Just avoid free VPNs – they're unreliable and often don't work.
Q: Can I buy a local SIM at the airport?
A: Yes, but airport stores often have limited plans and higher prices. I recommend going to a regular China Unicom store in the city for better options.
Q: What if I don't speak Chinese?
A: Don't worry! Just point at the plan you want, hand over your passport, and say "yes." Most stores have a price chart on the counter. Keep it simple and you'll be fine.
Final Thoughts From a Local
Look, I've seen every combination of SIM setup fail and succeed. Here's my honest bottom line:
If you're here for a week or less: Get the Trip.com eSIM. It just works. No VPN, no language barrier, no store visit. You'll be online before you leave the airport.
If you're here for more than a week: Bite the bullet and get a China Unicom SIM. The 15 minutes in the store is worth it. You'll get 5G speeds, a local number, and access to local apps that make life in China genuinely easier.
Either way: Install Mullvad VPN on your phone and laptop before you arrive. You might not need it with an eSIM, but if you switch to local Wi-Fi or need AI tools, you'll be glad you have it.
