The Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!).
Maps not updated in real-time. Don’t worry though, we log the information you share with us to improve our coverage maps and signal information. We’re working hard to make sure the data you contribute to the project is available to everyone as quickly as possible.
- Not all towers and wireless routers are in our database - we’re working on it!
- Verizon & Sprint (CDMA) users will see only one connected tower at a time
- Moving in the direction of your cell tower (the signal compass) will not always improve reception due to interference effects/local geography.
- For GSM, cell tower are identified via cell id and location area code (CID and LAC)
- For CDMA cell towers are identified via Network ID, Base sub-station ID and system ID (NID, BSSID and SID).
