An Indian regional context driver for SMS::Send to send SMS text messages via eSMS Kerala gateway in India -

This is not intended to be used directly, but instead called by SMS::Send (see synopsis above for a basic illustration, and see SMS::Send's documentation for further information).

The driver uses the eSMS's HTTP GET API mechanism. This is documented in the Developer documentation available to customers of the service.



Constructor, takes argument pairs passed by SMS::Send, returns an SMS::Send::IN::eSMS object. See usage synopsis for example, and see SMS::Send documentation for further info on using SMS::Send drivers.

Additional arguments that may be passed include:-


The HTTP API endpoint. Defaults to


Whether debugging information is output or not.


Send the message - see SMS::Send for details. Briefly it requires two principal parameters to function:


Used to supply the 160 character message body.


Destination mobile phone number in India. Numbered as per NNP 2003 i.e. 91XXYYYZZZZZ.


Recipient phone number checks

Additional checks have been placed into the code for ensuring compliance with Indian National Numbering Plan 2003 (and its subsequent amendments). This measure is expected to prevent user generated errors due to improperly formatted or invalid mobile numbers, as noted below:

Example 1 : "819XXXXYYYYY"

81 is an invalid country code. As an India specific driver, the country code must be 91.

Example 2 : "9XXXXYYYYY"
Example 3 : "8XXXXYYYYY"
Example 4 : "7XXXXYYYYY"

As per National Numbering Plan 2003, cell phone numbers (both GSM and CDMA) have to start with 9XXXX / 8XXXX / 7XXXX series (access code + operator identifier). A phone number that does not fit this template will be rejected by the driver.

Example 5 : "12345678"
Example 6 : "12345678901234"

A phone number that is less than 10-digits long or over 12-digits long (including country code prefix) will be rejected as invalid input as per NNP 2003.

Example 7 : "+91 9XXXX YYYYY"
Example 8 : "+91-9XXXX-YYYYY"
Example 9 : "+919XXXXYYYYY"
Example 10 : "09XXXXYYYYY"

Phone numbers formatted as above, when input to the driver will be handled as "919XXXXYYYYY"

Driver development cost was sponsored by State Librarian, State Central Library, Trivandrum, Kerala. Also noted thankfully the facilitation done by KELTRON and other individuals associated with the project who made it possible to write and release this driver as Free Software.

Severel existing drivers both international and regional, were inspiration and source for liberal copying.
