# What does offlineConnectionError (code 35) mean in the purchases SDK?

The purchases SDK raises offlineConnectionError (code 35) on iOS when a request fails because the device is not connected to the internet.

## Quick facts

| | |
|---|---|
| Error | `ErrorCode.offlineConnectionError` (iOS), no Android member, code 35 |
| Where | Purchases SDK (iOS, Android and the hybrid SDKs built on them) |
| What the vendor says | Error performing request because the internet connection appears to be offline. |

## Cause

- A request failed with the system's "not connected to the Internet" error, which the SDK maps to this error. It differs from `networkError`, which covers every other network failure.
- Airplane mode, no signal, Wi-Fi without internet, or cellular data blocked for the app.
- Android has no member for this code; the same situation raises an `IOException`, which becomes `NetworkError`.

## Fix

1. Show an offline state and keep the app usable with cached data.
2. Retry offerings or customer info when your platform's reachability callback says the network is back.
3. Keep gating features on the cached entitlement state the SDK already holds.
4. On iOS, check that cellular data is allowed for the app in Settings.

## Example

```swift
// The purchases SDK throws `ErrorCode` values; match the one you handle and let the rest fall through.
func handle(_ error: Error) {
    guard let code = error as? ErrorCode else {
        print("Not a purchases SDK error: \(error)")
        return
    }
    switch code {
    case .offlineConnectionError:
        // Offline is not a purchase failure: keep cached access and retry when the network returns.
        print("You appear to be offline")
    default:
        print("Other purchases error: \(code.description)")
    }
}
```

## How the RevenueDot SDK reports it

Customers who already paid keep the access the SDK cached, and a device that is offline never reaches RevenueDot. Deep dive: [revenuedot.app/errors/offline-connection-error](https://revenuedot.app/errors/offline-connection-error).
