You Cannot Receive Bank SMS in China

Last checked: 2026-06-05 Source links listed below Use with a backup path

Short Answer

Section titled “Short Answer”

Keep the original number reachable, set up app-based approvals before travel, and avoid payment paths that depend only on SMS once you are already at a counter.

Situation

Section titled “Situation”

Your bank, card issuer, or payment app sends a code to your home number, but the SMS does not arrive in China. A payment or login may be blocked.

Before You Start

Section titled “Before You Start”
  1. Turn on roaming for the home number if needed for SMS.
  2. Install and log in to the bank app before departure.
  3. Add app-based approval or backup codes where supported.
  4. Bring a second card from another issuer.
  5. Keep a cash reserve for payment failures.

Steps

Section titled “Steps”
  1. Check whether the home SIM is active and selected for SMS.
  2. Move to a place with better signal before requesting another code.
  3. Use bank-app push approval if available.
  4. Check email or authenticator alternatives.
  5. Call bank support only from a secure setting, not a checkout line.
  6. Use another payment method if the purchase is urgent.

If It Fails

Section titled “If It Fails”

Watch for these signals:

  • SMS never arrives after a cooldown.
  • The bank blocks foreign roaming SMS.
  • The payment page times out waiting for approval.
  • You cannot log in to the bank app after arrival.

Stop Retrying When

Section titled “Stop Retrying When”
  • The payment is time-sensitive.
  • You have requested two codes without success.
  • Another payment method is available.

Backup

Section titled “Backup”
  1. Use a different card already approved.
  2. Use Alipay or WeChat Pay if they do not require a new bank challenge.
  3. Use cash for small transactions.
  4. Contact the bank from the hotel before trying again.

What Not To Assume

Section titled “What Not To Assume”
  • Do not assume SMS works just because data works.
  • Do not remove the home SIM if it receives bank codes.
  • Do not rely on one bank for all China payments.
