Installation
Preparation
Before installing the i-gsm02, please consider the type of network
account and the physical location of the unit and its antenna.
Choosing a network account
Avoid using a pay as you go account. If you must, then be aware
that the i-gsm02 cannot warn you of low credit. Set up regular top-
ups for the account or manage it through the internet (if the
provider gives you that option).
Note: This module is not currently compatible with 3G sim cards.
