GUIDE TO CHOOSING & ACTIVATING, USE WECHAT/ALIPAY IMMEDIATELY

Are you going to Guangzhou, Shenzhen, or Yiwu for business or sourcing trips? Stable connectivity is a “must-have weapon” to use WeChat, Alipay, book DiDi, Meituan, navigate maps (Baidu/AMap), and communicate with logistics. Below is the latest guide to choosing China SIM/eSIM, with support services from Viet Trung Company.

China SIM Service

1) What types of China SIMs are there?

a) Travel SIM (prepaid/visitor SIM)

  • Valid for 5–30 days, mainly 4G/5G data, sometimes with local calling minutes.

  • Suitable for fairs, short-term sourcing trips, without long-term registration.

b) Travel eSIM (QR code, no SIM tray needed)

  • Receive QR code via email, install in 1–2 minutes, convenient for dual-SIM phones or SIM-tray-free iPhones.

  • Flexible top-up/extension online.

c) Local SIM (prepaid/postpaid – requires “real-name” registration)

  • Requires passport information and face scan at carrier/agent counter according to 实名制 regulations.

  • Suitable for long-term stays, receiving Chinese bank OTP, and activating cheap monthly services.

Popular carriers: China Mobile (移动) – wide coverage; China Unicom (联通) – flexible pricing/plans; China Telecom (电信) – strong in many cities.

2) Should you choose SIM or eSIM?

  • Short trips (3–15 days), quick setup → choose eSIM: no need to remove SIM, keep your Vietnam number; 3GB/5GB/10GB/20GB/30GB packages valid daily or 7–30 days.

  • Need local calls, frequent SMS, long stay → choose local SIM and complete real-name registration at carrier counters.

  • Multiple cities/fairs: prioritize high-speed 5G/4G 10–30GB packages, downgrade to low speed after quota to ensure messaging/navigation.

5) Activation & Usage Guide

a) With eSIM

  1. Check if your device supports eSIM (iPhone XS and newer, many Android models).

  2. Enable Wi-Fi, scan eSIM QR code (Settings → Cellular/Mobile → Add eSIM).

  3. Set Data SIM to China eSIM, enable Data Roaming as instructed.

  4. APN: usually auto-configured, Viet Trung provides APN if needed per carrier.

  5. Restart device, enable mobile data → check 4G/5G icon.

b) With physical SIM

  1. Insert SIM upon arrival in China.

  2. Enable mobile data; if no network, select carrier manually (Mobile/Unicom/Telecom).

  3. Send activation SMS as instructed (if required); configure APN if needed.

Stability tip: keep 1 Vietnam SIM for OTP, 1 China eSIM for data. For iPhone, set Voice & Data → 5G Auto/4G.

6) WeChat/Alipay – Verification Notes

  • WeChat/Alipay often require an active phone number for OTP; eSIM/SIM with SMS-capable numbers are more convenient (not all packages provide numbers).

  • Policies may change; Viet Trung offers consultation before departure.
