I received it in three weeks. It communicates with Arduino without problems. Please, bear in mind to: define the SIM card without PIN and define the connection to be 2G (or GSM) networks, only. You can make these definitions by putting the SIM card in a cellular phone and go to telephone settings..... Otherwise, it will not register to Mobile Phone networks even if the SIM card is functional in this cellular phone.

Ainda não testei o modem mais a aparência e a construção física da placa estão ok. Alta qualidade e as soldas estão perfeitas. a antena e o cabo "pig tail" também são de qualidade. Recomendo.

Works very fine. Tested with Atmel atmega328p, very easy to implement it with AT commands.

Got exactly what is on the photo. I have chosen Type 2 Glue stick antenna version, but there was no antenna.

Pas identique à la photo car le module n'est pas livré avec l'antenne !! je pensais qu'il fallait choisir l'option mais pas que l’antenne était en option !! donc attention ce n'est pas livré avec l'antenne!! sinon de bonne qualité mais pas encore testé !! car pas d'antenne !! N'oubliez pas de relever le SKU de vos articles en cas de soucis !!

Long delivery time. :( I thought that the principle has been set ... but no! Compact design! Use of purely Transmission Center.
