Again, it was wrong tag! Fixed it for good this time. ------------------ I have looked at the site suggested by Lucian and also by Ake Hedman). These products seem very usefull for my purposes. Thank you. I have some questions (I am very new to GSM). They seem to have 3 versions GSM, GPRS, PCS. They seem to be having the same features. If I would like to use these products with a regular SIM card and be able to send data as well SMS, which one I should be choosing, it is not clear? I will be connecting these units to a PIC or another MCU and send some data at defined intervals. Also, I could not find information about data sending, although they all clearly send data. How do I send data, after dialing a number and making a connection? Do you suggest any of their evaluation kits? Any suggestion is appriciated.
