Ready to catch Pokémon, only to see “GPS Signal Not Found (11)” or “Failed to Detect Location (12)”?
Both errors can prevent the map from loading correctly. Your Trainer may remain in one place, while nearby Pokémon, PokéStops, and Gyms disappear. However, these two errors do not always have the same cause.
Error 11 is usually related to GPS signals or location permissions. Error 12 is more commonly associated with invalid location data, outdated location changers, or incompatibility with Pokémon GO’s location detection.
This guide explains the differences, provides quick iPhone troubleshooting steps, and shows how iFlowGo can provide a more stable location-changing experience.
Pokémon GO Error 11 vs. Error 12
| Error | What It Means | Common Causes |
|---|---|---|
| GPS Signal Not Found (11) | Pokémon GO cannot receive a GPS signal | Location Services disabled, Precise Location turned off, weak GPS signal, or network issues |
| Failed to Detect Location (12) | Pokémon GO cannot verify or correctly read the location | Invalid location data, outdated spoofing tools, modified apps, or compatibility problems |
| Blank map or frozen character | The game is not updating your position | Poor network connection, game lag, or an iOS/Pokémon GO version issue |
If you have never used a location changer, start by checking your iPhone’s permissions, GPS signal, and internet connection.
If Error 12 appeared while using an older location tool, that tool may no longer be compatible with the current version of Pokémon GO.
Why Can’t Pokémon GO Detect Your Location?
1. Location Permissions Are Not Enabled
Pokémon GO is a location-based game. Without access to your iPhone’s location, it cannot load nearby Pokémon, PokéStops, or Gyms.
Go to:
Settings → Privacy & Security → Location Services → Pokémon GO
Then confirm that:
- Location Services are enabled
- Pokémon GO can access your location while using the app
- Precise Location is enabled
2. The GPS Signal Is Weak 🛰️
Underground stations, basements, tall buildings, and dense urban areas can block or weaken GPS signals.
Move closer to a window or go to an open outdoor area. Wait a few moments, then reopen Pokémon GO.
3. Your Internet Connection Is Unstable
Pokémon GO needs both location data and an internet connection. Even when GPS is working, an unstable Wi-Fi or mobile connection may prevent the map from loading.
Try switching between Wi-Fi and mobile data. You can also enable Airplane Mode for a few seconds, turn it off, and reconnect.
4. Pokémon GO or iOS Is Outdated
An older version of Pokémon GO may not work correctly with the current version of iOS. Temporary problems can also appear shortly after a game or system update.
Check the App Store for Pokémon GO updates, then restart your iPhone.
5. Your Location Changer Is No Longer Compatible
Pokémon GO’s location-detection system changes over time. Older tools may rely on outdated GPS methods or modified game clients, making Error 12 more likely after an update.
In this situation, restarting the game may not be enough. You may need to stop the old tool and switch to a solution that supports the current Pokémon GO environment.

How to Restore Pokémon GO Location with iFlowGo
The basic process is straightforward:
- Open iFlowGo on your computer.
- Connect your iPhone through Bluetooth.
- Wait for the location to initialize.
- Select a destination or movement route.
- Open the official Pokémon GO app and check the map.
If you previously used another location changer, close it completely and restart your iPhone before connecting to iFlowGo. Running multiple GPS tools at the same time may create conflicting location data.
For detailed setup instructions, follow the iFlowGo video tutorial.
What Does iFlowGo Virtual GO Plus Do? 🤖
In addition to changing your GPS location, iFlowGo includes Virtual GO Plus, which simulates a physical Pokémon GO Plus accessory.
Once connected, it can:
- Detect nearby Pokémon automatically
- Attempt Pokémon catches automatically
- Spin nearby PokéStops
- Collect Poké Balls and other items
- Reduce repetitive tapping and manual throws
- Accumulate Stardust and XP while following a route
Virtual GO Plus does not require you to purchase a separate GO Plus device. According to the iFlowGo Virtual GO Plus guide, the first setup requires pairing, while future sessions can reconnect more quickly.
Automatic catches are not guaranteed to succeed. Virtual GO Plus also consumes Poké Balls, so make sure your Item Bag and Pokémon Storage have enough available space.
Quick Troubleshooting Checklist 🔧
If Pokémon GO still cannot detect your location, try these steps in order:
- Confirm that iPhone Location Services are enabled.
- Enable Precise Location for Pokémon GO.
- Switch between Wi-Fi and mobile data.
- Close and reopen Pokémon GO.
- Check for Pokémon GO and iOS updates.
- Restart your iPhone.
- Close any other location-changing tools.
- Reconnect iFlowGo and initialize the location again.
- Reinstall Pokémon GO only if the previous steps fail.
Following this order helps you avoid unnecessary network resets or game reinstallation.
Frequently Asked Questions
Are Errors 11 and 12 the same?
No. Error 11 usually means Pokémon GO cannot obtain a GPS signal. Error 12 is more commonly related to invalid location data, an incompatible location changer, or a location that cannot be verified.
Can a VPN fix Pokémon GO Error 12?

No. iFlowGo works with the official version of Pokémon GO downloaded from the App Store.
Does iFlowGo require jailbreaking?
No. You can use iFlowGo without jailbreaking your iPhone.
Is using a location changer completely risk-free?
No third-party location changer can guarantee zero risk. Players should follow Pokémon GO’s Terms of Service and avoid unrealistic behavior, such as repeatedly jumping between distant countries or moving at impossible speeds.
How do I restore my real location?
Stop location simulation in iFlowGo and restart your iPhone. The device should then reconnect to its real GPS location.
Final Thoughts 🎮
Pokémon GO Errors 11 and 12 do not always mean that something is wrong with your account.
