before you start to play Tu Tu Gourmet Run with Big Ears, you need to make sure that your mobile phone is connected to the Internet. Here are some common ways to connect to the Internet:

1. Wi-Fi connection: Turn on the Wi-Fi function in the phone settings and select an available Wi-Fi network to connect. After entering the password (if any), you can connect to the Internet.

2. Mobile data connection: If your mobile phone package contains mobile data traffic, you can connect to the Internet by turning on the mobile data option in the phone settings.

Please note that the game may take some time to download and update the game resources, so please make sure that your network connection is stable and fast enough. If you can't connect to the Internet or encounter other network problems, you can contact your Internet service provider or mobile phone manufacturer for help.
