Hello, I am just looking for some advice, I recently purchased: SIM808 GPS/GPRS/GSM Arduino Shield(Product Code : RB-Dfr-665), but I have not been able to collect any GPS data? I am getting the “Open the GPS power success” in the serial terminal when I connect to an external power source. But nothing else is happening.
Another query I am wondering about…I have purchased a GiffGaff SIM card that says it is 2G/3G/4G compatible. Should this be okay for the device? Also I am in the UK.
Any advice would be great for a newbie.
Did you follow the instructions indicated in the product’s Wiki ?
What is the external power source that you are using ? (voltage and current)
Also, please note that the GPS antenna of the SIM808 GPS/GPRS/GSM Arduino Shield should be as near as possible to a window and it will take approximately 10 minutes for the satellites to lock.
The Shield works with Quad-band 850/900/1800/1900MHz 2G GSM network. Please verify if your Sim card is within these specifications.
Hello there, I did follow the instructions on the wiki page, I am using a normal cable to connect the Arduino to my PC and then a separate external 9V battery into the jack.
At one point I left the antenna on the edge of a window for over 5 hours but no data was received.
Could I ask for some advice as to how I would check if the SIM card is within these specifications?
Thank you for your help

Could you post a picture of your SIM808 GPS/GPRS/GSM Arduino Shield ?
Here is few points to verify :
]Please try to use an external power supply (7V to 12V) that can supply at least 2Amps./:m] ]Connecting the GPS antenna the uFL SMT antenna connector./:m]
*]Try to use the shield outdoor. In the product’s Wiki :
/*:m] ]The switch on the shield should be in “None” position while uploading the sketch. After uploading the sketch, the switch should be in “Arduino” position. Press the Boot button./:m]You would need to communicate with your SIM provider, they should be able to provide you with these information.
Hello,
Above is a picture of the exact model that I have, obviously I have connected the GPS antenna to the shield.
-Yes I am using a 9V power supply
-The antenna is attached
-I have taken my laptop outside to try to receive GPS
-I will keep trying, but I have been using the “NONE” and “Arduino” switches as instructed
Okay I have asked them, they stated that their SIM cards are backwards compatible with 4G/3G/2G.
Should the GPS data come through on the Arduino serial monitor? as so far this is what I am receiving from the Arduino serial monitor…
AT
Sim808 init error
AT
Sim808 init error
AT
AT+CFUN=1
AT+CPIN?
AT+CGNSPWR=1
AT+CGNSTST=1
Open the GPS power success
Can you try the AT Commands in the product’s Wiki to get GPS data through USB debugging ?
Please don’t forget to put the switch to **USB_DBG **and to place the GPS antenna outdoor.
Please let us know how it goes by posting screen-shots of the result.
I know this post is old, but recently I bought this board as well , board have manufacture bug as programing swich positions mix 1 with 3. Arduino dosnt give any error just to program use position 3- arduino, to see serial monitor use 1- None.
My question: how I can use serial monitor with this board as they on same port with Sim808 ? I don’t want use dedicated library as no tutorial how to make Gps GSM tracker
You can use the switch position 2 (USB_DBG) to communicate and debug directly the SIM808 chip through the serial port. The Arduino board will act as a pass-through.
You can’t use the serial monitor while the Arduino is communicating with the SIM808 module.
