If you have a mobile phone signal in your data centre, the usual way is 
to get a GSM modem or similar device hooked up to the serial port of 
your monitoring server, so it can send an SMS. However, this doesn't 
help if commercial power is out as some mobile base stations might not 
have much/any battery backup.

Although it's possible to use gnokii with a mobile phone to do the same, 
most phones write to the SIM card every time they send an SMS, and a SIM 
card being flash memory has a finite number of read/write cycles before 
it dies.
