Frequently Asked Questions

How do I change the baud rate on this modem?

Send the AT command AT+IPR=<rate> (e.g., AT+IPR=115200) over the serial interface. The modem will respond with “OK” and switch to the new baud rate immediately.

What power supply should I use for reliable operation?

Use a regulated 3.4–12 V DC supply capable of delivering at least 2 A peak current to handle GSM transmission bursts. The onboard regulator ensures stable voltage for the SIM800C chipset.

Can I use this module for GPRS internet connectivity?

Yes. After registering on the network, configure APN settings using AT+CGDCONT and initiate a TCP/IP session with AT+CIPSTART to establish a GPRS data link for internet access.
