Quick answer
For ebooks stored on your phone, keep the file on your phone, open it before you need it, and check which optional features require the internet.
Offline ebook reading keeps the book usable when Wi-Fi or mobile data is unavailable.
Store a real local copy
A file visible in a cloud app may still be online-only. Download it to the device or mark it available offline.
Test in airplane mode
Open the book, move to another page, search, and add a bookmark while airplane mode is on.
Check privacy settings
Read the app’s privacy page. Look for account requirements, cloud sync, analytics, and whether books or notes are uploaded.
Keep backups separate
Local reading protects against network problems, but it does not protect against losing the phone. Back up important files separately.
Reader option
Readream is offline-first. Books, notes, progress, highlights, saved words, and Writer data stay on the device. Pro uses the internet only when you choose to download an optional voice model.
If the first fix does not work
Try another known-good ebooks stored on your phone 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.
