Temporary Chinese Number for Xiaomi Hey+ Plus App

November 5, 2025 / Guides / By / 7 minutes of reading

Introduction

The Xiaomi Hey+ Plus smart band, distributed by Xiaomi in China and manufactured by RYEEX, requires a Chinese phone number to unlock its companion app, Hey+ Plus. This presents a challenge for international users who don’t have a Chinese phone number. (Updated November 2025)

The Hey+ Plus smart band offers impressive features including heart rate monitoring, sleep tracking, NFC payments (in China), and up to 18 days of battery life. However, without access to the companion app, these features remain locked and unusable for international users. This guide will show you exactly how to bypass this restriction safely and easily using temporary Chinese phone numbers.

Challenges with Registration

International users face challenges registering for the Xiaomi Hey+ Plus app due to the hardcoded Chinese phone number requirement.

The Hey+ Plus app mandates that users enter a Chinese phone number to receive an SMS verification code. Unfortunately, the country code is hardcoded, meaning international numbers cannot be used. This renders the band practically unusable for those without access to a Chinese phone number.

Common registration obstacles include:

  • Region Lock: The app automatically detects and requires Chinese mobile numbers starting with +86
  • SMS Verification: The app won’t proceed without successful SMS verification from a mainland Chinese carrier
  • Language Barriers: Initial setup screens may appear only in Chinese, adding another layer of complexity
  • App Store Restrictions: The Hey+ Plus app may not be available in international app stores, requiring APK sideloading on Android

Why Does Hey+ Plus Require a Chinese Number?

Understanding why this requirement exists can help you navigate the solution better. In 2025, Chinese tech companies like Xiaomi implement phone number verification for several reasons:

  • Regulatory Compliance: Chinese law requires real-name registration for many digital services
  • Regional Services: Many features like NFC payments and local health data syncing are China-specific
  • Anti-Fraud Measures: Phone verification helps prevent unauthorized account creation and device cloning
  • Market Segmentation: Different regions may have different app versions with varying features and pricing

Despite these restrictions, international users can still access the full functionality of their Hey+ Plus devices using the temporary number solution detailed below.

  • If the first number doesn’t receive a code within 2 minutes, try a different Chinese number

Troubleshooting Common Issues

Even with the right tools, you might encounter some challenges. Here are solutions to the most common problems in 2025:

Code Not Received:

  • Wait up to 3 minutes as Chinese SMS can sometimes be delayed
  • Try requesting the code again after 60 seconds
  • Switch to a different temporary Chinese number
  • Ensure you’re entering the number without spaces or dashes

App Won’t Accept the Number:

  • Double-check you’re not including the country code if it’s pre-filled
  • Clear the app cache and try again
  • Reinstall the Hey+ Plus app and start fresh
  • Try using a VPN connected to a Chinese server

Verification Code Invalid:

  • Enter the code exactly as shown, including any spaces
  • Ensure you’re using the most recent code received
  • Check that the code hasn’t expired (usually valid for 5-10 minutes)
  • Request a new code if the current one isn’t working
