Hi, can you give me other cells?
Could be that they are wrong or that this cell is not in Google database.

Halo Boris,
Iam tested my cellId and LAC is worked.
Iam interested with this script.
But iam newbie and want to learn it.
Can you upload one bundled all script php and html, so i can upload to my hosting to runing it.

many-many thanks

logbor said:

And for you info:
i was upload to my hosting: celltrack.html and cell.php
But when i click “send”, not open the result.

I guess i need the right html.

Thanks
