AT Commands


and then


This should give you a result like:

+CREG: 2,1,"1030","639E"

Working through the 4 returned values, the "2" reflects the
current "+CREG" setting (2 means "Enables unexpected network
registration and location information messages" ), "1" indicates
that the phone is registered with the network, "1030" is the
Location Area Code (LAC) in hex (4144 decimal), and "639E" is the
CellID (CI) in hex (25502 decimal).

If the cell name itself is being broadcast as a Cell Broadcast
message, it can be read in PDU format and decoded. Assuming
channel 50 is being used for this, the composite command to read
it is


The PDU results (unsolicited for each new broadcast) can be
decoded according to GSM 03.38. Please let me know if you need
further info.

Hi Tommy,

That could tell you what cell your modem is connected to ... but it won't tell you what cell someone who is sending you an SMS message is connected to.

I'm not aware of any way to query this location information over a GSM modem. Some operators sell access to be able to query for this type of information as an LBS service, but when it is available, it involves a lot of legal agreements with the mobile operator regarding privacy issues.
