Staying connected in China as a foreigner is easier than ever in 2026. You have two main options: buy a physical SIM card after arrival (at the airport or a carrier store), or activate an international eSIM before you depart. This guide compares both options across cost, convenience, and compatibility, so you can choose the best fit for your trip.

Overview

China has three major mobile carriers: China Mobile, China Unicom, and China Telecom. All three offer short-term prepaid plans for foreign visitors, available at major airports and official carrier stores. In addition, international eSIM providers such as Airalo, Holafly, and Nomad offer China-specific or Asia regional data plans that you can activate before boarding your flight.

The key trade-off: a Chinese SIM gives you a local phone number and is cheaper for longer stays, but requires in-person registration. An international eSIM is instant and requires no paperwork, but typically costs more per GB and may not include a Chinese phone number.

Airport SIM Cards

Buying a SIM card upon arrival is the most reliable way to get a local Chinese number. Here is what you need to know:

• Where to buy: Carrier kiosks in the arrivals hall of major airports (Beijing PEK, Shanghai PVG, Guangzhou CAN, Chengdu TFU). Also available at official carrier stores in city centers. Note: Airport kiosks typically operate from 6:00 AM to midnight. For late-night arrivals, use airport Wi-Fi to contact your hotel or purchase an eSIM as backup.
• Required documents: Your passport. The SIM card must be registered under your real name as required by Chinese law.
• Cost: Typically RMB 100-200 (USD 14-28) for a prepaid plan with 20-50GB of data and a local number, valid for 30 days.
• Setup time: 10-20 minutes at the kiosk. The staff will help you activate the SIM and set up your phone.

International eSIMs

An eSIM is a digital SIM that you install on your phone before traveling. It is the most convenient option for short stays. Here is what you need to know:

• ⚠️ Compatibility check: Before purchasing, verify your phone is unlocked and supports eSIM. Many carrier-locked phones (e.g., AT&T, Verizon) and older Android models do not support eSIM. Use your provider's IMEI checker or dial *#06# to confirm.
• Where to buy: Through eSIM provider websites or apps (Airalo, Holafly, Nomad, etc.). Purchase and install before departure.
• Required documents: None. You purchase online and activate with a QR code or app installation.
• Cost: Typically USD 10-50 for 5-30GB of data, valid for 7-30 days. Prices vary by provider and data volume.
• Setup time: 5-10 minutes to purchase and install. No airport visit required.

How to Choose

Here is a simple decision guide based on your trip length and needs:

• Short trip (1-7 days): Get an international eSIM. It is instant, requires no airport visit, and is perfectly adequate for maps, messaging, and basic browsing.
• Medium trip (1-2 weeks): Either option works. If you need a Chinese phone number for food delivery apps or bike sharing, get a physical SIM. Otherwise, stick with eSIM for convenience.
• Long trip (2+ weeks): Get a Chinese SIM card. The cost savings add up, and a local number is essential for many daily services.

What about using your home carrier's roaming?
International roaming from your home carrier usually costs USD 5-10 per day and routes data through servers outside China, which may allow access to blocked sites without a VPN. However, the cost adds up quickly for longer stays. For a two-week trip, roaming can cost USD 70-140 — far more than any local or eSIM plan.
