COMECheck a usable connection before COME APK download
Before starting a file transfer, confirm that the phone has usable internet access through the connection you intend to use.
Check more than the icon
A Wi-Fi or mobile signal indicator does not guarantee that a web request will succeed. Open a trusted ordinary page and inspect any network sign-in or connectivity message. Do not enter app credentials into an unrelated portal.
Understand the connection terms
Review your own data plan or the network's conditions. A download may pause under a data rule or unstable connection. Do not assume that a small listed file means there can be no additional traffic or retries.
Start one transfer
Once the connection works, use the known app entry and let one intended download finish. Check the browser's status rather than repeatedly pressing the button. If it fails, retain the exact message and time.
A useful next step
Continue to Android installation only after the browser confirms completion.
