Review on Wireless Quad-Band GSM/GPRS/GPS Shield Based On SIM808 Onboard CP2102 MIC29302 Phone Talk Speaker Module @XYGStudy by Kyle Earley
Works very well Works well in weak signal locations.
I use this to allow my house to send me text messages about certain events. I don't use the data portion, I'm only planning on spending $5 a month to send text messages. With an additional antenna for outdoor mounting, it was reliable. The included antenna was fine too, but while I was in my garage messages were sometimes delayed as the radio reestablished contact.
