Hi,

To find out the CLI (Caller ID) of the requesting device refer to the http header of the request.
It will appear in fields like HTTP_X_UP_SUBNO or HTTP_USER_AGENT depending on the WAP gateway.

The thing is that not all WAP gateways and not all carriers send this information. There all kinds:
1. WAP gateways that will never send any information on the cellular device.
2. WAP gateways that will send only to sites which appear in a "trusted list". This is a method to make sure that only WAP sites which are known/paid/signed a contract to (with) the operator get the information.
3. Gateways that always send the information.

In order to handle privacy issued some gateways do not send the actual phone number but instead a identifying number which is always the same for a specific device. This will allow you to personalize content for the user without actually knowing his phone number.
