Traveling Xi’an as a Foreigner: My Tips on China SIM & ID Check

Landing in Xi’an for the first time, I was buzzing with excitement to explore the Terracotta Army, cycle on the ancient city walls, and lose myself in the Muslim Quarter’s street food. But before I could even grab my backpack, I hit my first hurdle: China’s strict SIM card and ID check rules. As a foreign traveler, I’d heard whispers about “real-name registration” but had no idea how much it would shape my trip. After a week of fumbles, fixes, and figuring things out, here’s my no-BS guide to navigating SIM cards and ID checks in Xi’an—so you can skip the stress and start exploring.

First Things First: Why China Cares About Your ID

Let’s get this out of the way: China requires all SIM cards to be registered with a real name and ID (for foreigners, that’s your passport). This isn’t just bureaucracy—it’s a national security measure to prevent fraud, spam, and illegal activities. For travelers, it means you can’t just buy a prepaid SIM at a convenience store like you might in Europe or Southeast Asia. You’ll need to go to an official carrier store (China Mobile, China Unicom, or China Telecom) and register on the spot.

Pro tip: Don’t skip this! An unregistered SIM will either not work at all, or get blocked within 24 hours, leaving you without data or calls—bad news when you’re trying to book a taxi or find your hotel.

Traveling Xi’an as a Foreigner: My Tips on China SIM & ID Check

Step 1: Get Your SIM Card at Xi’an Airport (Easiest Option)

I landed at Xi’an Xianyang International Airport (XIY) and decided to grab my SIM card right there—genius move. The airport has dedicated counters for all three carriers, with English-speaking staff (though they’re sometimes busy, so patience helps).

Which Carrier to Choose?

• China Mobile: The biggest carrier, with the best coverage in rural areas (useful if you’re planning day trips to places like the Terracotta Army or Mount Huashan).
• China Unicom: Cheaper data packages, and great in cities like Xi’an.
• China Telecom: Less common for travelers, but solid in urban areas.

I went with China Mobile because I knew I’d be heading out of the city, and their “Tourist Package” was perfect: 20GB of high-speed data for 30 days, plus 100 minutes of calls, for ¥98 (around $13).

What You’ll Need at the Counter:

1. Your passport (they’ll scan it).
2. Your visa (sometimes they ask to see it, though not always).
3. A Chinese phone number (they’ll help you pick one on the spot).

The whole process took 15 minutes. The staff activated my SIM, put it in my phone, and even helped me set up mobile data. Bonus: They gave me a little booklet with English instructions for checking balance and topping up.

Step 2: The ID Check—It’s Not Just for SIM Cards

Here’s the thing: China’s “real-name system” isn’t just for SIMs. It pops up everywhere, and if you’re not prepared, it can derail your day. I learned this the hard way when I tried to buy a high-speed train ticket to Luoyang.

What is the ID Check?
Nearly every service in China—from booking train tickets to using ride-hailing apps (Didi) or even entering some tourist sites—requires your passport number linked to a “real name.” For locals, this is their national ID card; for us, it’s our passport.

Where You’ll Encounter It:

• Train/Bus Tickets: When buying tickets on apps like 12306 (China’s official railway app) or at the station, you’ll need to enter your passport number + name (exactly as it appears on your passport). Double-check spelling—one wrong letter, and you won’t get on the train.
• Ride-Hailing (Didi): When you book a Didi, the app asks for your ID to verify your identity. Don’t worry—they don’t store your passport details, but you must enter it to use the app.
• Hotel Check-In: Hotels register your passport with the police (this is mandatory). They’ll take a photocopy, so keep your passport handy.
• WeChat/Alipay: To use these apps for payments (super useful in Xi’an, where many places don’t take cash), you need to link your bank card and verify your identity. Alipay has a “Foreigner Registration” feature—just follow the prompts, enter your passport, and upload a selfie.

My Mistake (and How to Avoid It):
I tried to buy a train ticket at the Xi’an North Railway Station without the 12306 app set up. Big mistake. The ticket agent asked for my passport, then told me I needed to “register” first. I had to stand in line for the “Foreigner Registration” desk (separate from the regular ticket lines), where they helped me create a 12306 account. Added 30 minutes to my trip. Lesson learned: Download 12306 and register before you need to buy a ticket.

Step 3: Topping Up & Troubleshooting

Once you have your SIM, keeping it active is key. China SIM cards don’t “expire” in the Western sense—if you don’t use them for 3-6 months, they might be deactivated. But for a short trip, you just need to make sure you have enough data.

How to Top Up:

• WeChat/Alipay: Link your foreign card (Visa/Mastercard) to WeChat Pay or Alipay, then go to the “Recharge” section for your carrier (search “China Mobile” in WeChat, for example). You can add as little as ¥30 (around $4) for extra data.
• Carrier Stores: If you’re not comfortable with Chinese apps, pop into a China Mobile/Unicom store—they have English-speaking staff who can top you up.
• Airport/Convenience Stores: Some 7-Elevens or airport kiosks sell top-up cards, but you’ll need a Chinese phone number to use them (so this is less useful for travelers).

What If Your SIM Stops Working?
I was exploring the Muslim Quarter when my data suddenly cut off. Panic! I went to a nearby China Mobile store, and the staff told me my “tourist package” had expired (I’d been there 31 days). They helped me switch to a new 30-day plan on the spot—cost another ¥98, but I was back online in 10 minutes. Moral of the story: Check your expiration date (you can do this in the carrier’s app, like “China Mobile” on WeChat).

Step 4: Bonus Tips for a Smooth Trip

• Download VPN Before You Come: Google, Instagram, and Facebook are blocked in China. If you use a VPN, download it and set it up at home—once you’re in China, you can’t access the app stores to get it.
• Bring a Power Bank: You’ll be using your phone nonstop for maps, translations, and photos. Xi’an’s ancient walls have limited charging spots!
• Learn a Little Mandarin: Basic phrases like “Nǐ hǎo” (hello), “Xièxiè” (thank you), and “Wǒ xūyào bāngzhù” (I need help) go a long way. Google Translate’s camera feature is a lifesaver for reading signs or menus.
• Keep a Copy of Your Passport: Hotels will take a photocopy, but it’s smart to have a digital copy on your phone (in case you lose the physical one).

Final Thoughts

Xi’an is an incredible city—ancient history, amazing food, and friendly people. The SIM card and ID check rules might seem daunting at first, but they’re just part of the travel experience. Once you’ve got your SIM registered and your apps set up, you’ll feel right at home.

I spent my week cycling the city walls at sunset, slurping yangrou paomo (mutton soup) in the Muslim Quarter, and marveling at the Terracotta Army—all without a single SIM hiccup (after the first day, anyway). So pack your passport, grab a SIM at the airport, and get ready to explore. Xi’an is waiting—and now you’re ready for it.
