We are working to get the CELLID from AT Command called AT+CREG? its return's a wrong cellid some times its working inconsistently.
We convert the return cell id hexa decimal to decimal and check the mcc,mnc,lac & cellid with the google services to get the latitude and logitude while getting the latitude and logitude the google service says its a wrong cellid.
Issue is very critical to us.
We need to fix it soon can any please respond quickly why its returns wrong cellid.
