Note the following considerations before you set up SMS (SMPP) text message notification:
SMS (SMPP) notifications are for use with GSM mobile phones and other SMS-compatible devices. SMS notifications are generally much faster than (SMTP) text pager notifications, and some SMS service providers offer the additional benefit of replacing a previous notification with the latest one.
SMS service providers often charge for each SMS message or group of messages that Cisco Unity Connection sends. To reduce costs to your organization, consider limiting the number of notifications that you receive by a particular message type or urgency (for example, only urgent voice messages or only voice messages from specific callers or phone numbers).
Some SMS service providers replace the phone number that you enter in the From field on the SMS (SMPP) Notification Device page in the Messaging Assistant web tool with their own phone number. For an alternative way to include a callback number, see the Tip in Step 5 in Setting Up or Changing an SMS Notification Device.
The time stamp for an SMS (SMPP) notification on some phones reflects the time that the SMS message was sent by the SMS service provider to your SMS device. For this reason, the time stamp may not reflect your local time zone or preferred time format.
