How to turn off data when roaming
Follow these steps:
- Open WhatsApp and go to Options > Settings > Network > Cellular when roaming.
- Choose Disabled (use WiFi) if you do not want your phone to connect to your data network when roaming.
Your mobile service provider may charge you extra for using data while roaming. Thus, we recommend you configure WhatsApp so that it only connects to Wi-Fi networks when your phone is roaming. However, with this configuration, you will not receive messages while you are roaming and without Wi-Fi.
