Topic: GSM Shield V2 stops receiving messages (Read 294 times) previous topic - next topic


I have a GSM Shield V2 connected to Arduino Uno. I've created a project where I can control the pins of the Arduino either with SMS or with a button. The strange thing is that SMS control works for about a week, afterwards it seems the Arduino stops receiving the SMS, cause control with a button is still possible. I've contacted the network provider and they claim the SMS have been received and are marked as read so my question is what could I check and if anyone has experienced the same issues.
