On some of the newer documentation, SIMCom left the resistors off of the schematic, but clearly indicate in the text that they should be included. The attached image is the correct schematic for connecting a SIM Card to the SIM340.

Thank for your help and the last question,what is the last AT commands set manual of sim340DZ vesion? 1.02 is the same that Sim300D??I'm confused.
I have AT command Sim340DZ V1.02 and AT command Sim300D V2.0 but I'm not sure if the same, the seller tell me that is the same but I don't trust that the seller knows the topic

Thanks for you help

Hi, Wilasn, I think the AT Command sets are the latest. For there is no need to change the AT Command offenly. :). But different version SIM340D may have different spec.
