SMS 3G modem

Haven't really tried it but should be fine for SMS.

Similar RS232 device:

Both USB and RS232 use GSM modules from the same manufacturer (SIMCom). RS232 version might be bit better because of separate power supply though USB has an advantage of power control via scripts on LM5 so you can reboot the device if needed.
