FAQ of Industrial Cellular Modem USR-G785-E

Question:
Hi, I bought an indutrial cellular modem, the product model is USR-G785-E. I tried the new firmware to support PIN code.Even though the AT+CPIN command is useful, I would have especially wanted direct access to the cellular modem.
For example, for the moment the modem does not connect (+CIP='blank'), I guess it's related to our SIM card which is a card that is roaming...An AT+CREG would give me the information.
I noticed that communication (UART) was slowed down from the moment I entered the APN.

Answer:
Hi. What kind of SIM card are you using?
Can cellular modem USR-G785-E establish a connection and transfer data?
Is the transmission data slower?
Can a roaming SIM card work properly in a mobile phone?
 
Question:
We use an M2M SIM card, which works on the German network.
Since we are in France, the SIM card is used in roamming.
For the moment, the modem does not connect to the network, so there is no data transfer.
Yes all is OK in the mobile phone.
 
Answer:
Enter the command AT+UCPIN=pin code. Then restart the device.
