Connectivity strategy that works

For those arriving now, travel eSIM is usually the quickest start.

For longer stays, local SIM tends to complement with better cost and integration.

  • Confirm phone unlock.
  • Activate eSIM before takeoff.
  • Map where to buy local SIM at destination.
02

App stack for first week

Without the right apps, simple tasks become operational bottlenecks.

Prioritize payment, transport, map, translation, and communication.

  • Alipay and WeChat for services and payments.
  • DiDi for app-based transport.
  • Amap/Baidu Maps for local navigation.
  • WeChat and translator for daily support.
03

Risk of losing access

Losing connectivity during initial travel costs time and money.

Always keep an offline layer with receipts and addresses.

  • Screenshots of booking and route.
  • Emergency contact saved locally.
  • Power bank in carry-on.
