Yes. Uptime Infrastructure Monitor can send a regular format email to an SMS-enabled address by using the pager address field within the UIM user settings. For example: 123456@pcs.myphonecompany.com.
You also can use the script alert option to send a true SMS message via an SMS modem or an online SMS service. This option allows you to customize a script that sends alerts in your defined format and transport mechanism.
An example script to utilize an SMS modem can be found in Creating custom alert scripts in UIM Alert Profiles.
