?Notes:

Data accuracy is dependent on the device implementation of Android APIs. Not all manufacturers/devices implement fully/correctly Android APIs.
For Android < 5.0, Dual SIM is not supported for non-MediaTek devices, due to Android/device limitation.
You may use Mozilla Stumbler app to update the Mozilla MLS database in your area.
