I have been trying to figure out what is the problem in GSM shield telephonic , but does not send response and when i go the serial port I see SMS messages sender and does not change it stay forevery. I tried scan network example and the same problem . Any help please


I suggest you you try the TestModem program
The interest is to try if the modem of your shield is working properly
If it doesn't (as mine!) I am afraid it is hopeless...
