判断
中国のSIMを買うべきか、旅行者向けeSIMを使うべきか？
中国でデータと電話番号が必要なら ― 现地SIM vs 旅行者向けeSIM。
おすすめ
10日以内の短期滞在、または food デリバリーや注文アプリに現地の電話番号が必要な場合は旅行者向けeSIM。それ以外ならeSIMのほうが速く、安く済む。
The options
| Option | Best for | Tradeoff |
|---|---|---|
| 中国の現地SIM | 14日以上の滞在、+86番号が必要な方（アカウント認証やフードデリバリー用）。 | 携帯ショップでパスポート登録が必要。本人確認連動型。初期費用は約¥100。 |
| 旅行者向けeSIM | 短期旅行（10日以内）、eSIM対応スマホ、空港での設定を避けたい方。 | データ通信のみ。現地番号は非対応。$5〜$30。単独ではGFWを回避できない。 |
The verdict
10日以内の短期滞在、または food デリバリーや注文アプリに現地の電話番号が必要な場合は旅行者向けeSIM。それ以外ならeSIMのほうが速く、安く済む。

Other Internet & Connectivity decisions
eSIM or portable WiFi in China?
Pick eSIM for solo/couple travel. Pick pocket WiFi for groups or laptop-tethering needs.
Is a VPN worth paying for in 2026?
Yes if you need any Western service daily. No if you only need the China-native apps (which is most of the trip).
Which VPN actually works in China in 2026?
Astrill for serious use (and reliability); LetsVPN for budget trips; NordVPN if you already have it.
Do I really need a VPN in China?
Yes if you need any Western app daily; No if you can live without Gmail/Maps/WhatsApp for the trip duration.
Do I need a VPN before flying to China?
Yes, install and test it at home. You cannot reliably download VPN apps once inside China — set it up before landing.
