Quick answer
You can read CBZ comics offline if the file is stored on your Android device and the reader supports it locally.
Open the file once while online, then test it in airplane mode.
Offline checklist
Prepare these items before travel.
- Keep a full local copy of the file.
- Open the file once and move through several pages.
- Download any optional fonts, voices, or dictionaries.
- Add a bookmark so you can confirm progress is saved.
- Turn on airplane mode and open the same file again.
Cloud-storage warning
Seeing a file in Google Drive, Dropbox, or another cloud app does not always mean the file is stored on the phone.
Use the cloud app’s download or make-available-offline option, or save a copy to Android storage.
What may still need internet
Cloud sync, online dictionaries, web search, online translation, covers, and optional downloads may need a connection.
The file itself should not need internet if it is truly local and the reader works offline.
If it fails offline
Reconnect, download the file again, and confirm it appears in local storage. Then repeat the airplane-mode test.
If only one file fails, try another file of the same type before changing the reader.
If the first fix does not work
Try another known-good cbz comics example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
Detailed troubleshooting checklist
Work through the problem in this order: first check cbz comics itself, then the app, then Android or the device. Keeping that order prevents you from changing many things when only one part is wrong.
