Low power GSM module for sending sms

you should use AT+CFUN=x  command

look on datasheet,

Hi Lukasz,

Wavecom GSM module supports only AT+CFUN = 0 or 1.At setting current comes down to 30mA. But still not enough.

1. Is there any such complete GSM module which can be operated at low voltages like from Li-ion & can be send to sleep also when required.

In my previous job I used telit and quectel modules

both have at+cfun=9 mode

in this mode quectell have current less than 1mA

in CFUN=9 mode modem GSM waiting for SMS/GPRS data

incoming SMS or GPRS package wake up mode, and modem start working with full speed

P.S.

telit is very stable during work

but quectell is also good (quectel is very similar into simcom)

try find some of this modems but before choose check cfun modes,

on the market are many device:  "modem terminal"
you will found good for you
( telit modem terminal, quectel modem terminal, etc. )

but, when you want use very deep sleep mode CFUN=9
you must be careful during you choice,,,

I wrote that wake up from CFUN=9 is when sms or gprs data occur, but when you want wake up modem alone you must
change state on modem I/O pin, so you terminal must have
connection between this pin and uart pin (dtr for example)

of course you can use less deep sleep mode and wake up
modem using at command, (check it in modem app notes)

No soldering & other stuff required.

I need such a complete module

How about one of the many Arduino GSM/GPRS shields?
