emergency access numbers (for example, 911 or 112).

If your wireless service plan includes text messaging, you can also send text messages to contacts that appear in your fixed
dialing list.
To use fixed dialing, your wireless service provider must set up your SIM card for this service and provide you with a SIM
card PIN2 code. Depending on your wireless service provider and wireless network, this feature might not be supported.
