Simcity Buildit 1100.7 Error 🔥 No Survey
Unlike generic "connection failed" errors, the 1100.7 code is specific to SimCity BuildIt’s client-server authentication handshake. When you launch the game, your device sends a "handshake packet" to EA’s servers. Error 1100.7 occurs when the server receives that packet but finds it malformed, expired, or conflicting with a previously saved state.
In plain English: Your phone and the EA server are speaking different versions of the same language, or your local save file has a timestamp mismatch with the cloud save.
Common symptoms include:
Error 1100.7 typically points to a synchronization or connection issue between the game app on your device and the game’s servers. It often appears when:
You may see a message like:
“Unable to save your city. Please check your connection and try again. (1100.7)”
Final note: The 1100.7 error rarely means your city is lost. It’s almost always a temporary handshake problem between your device and the server. Stay patient, follow the steps above, and your city will be back online.
Happy building, Mayor! 🏙️
