I am working on sim module SIM700E-h and using Sakura Sim Card. I want to use this sim module for data(internet).So according to me we need to check 3 things.
-
International data roaming is enabled in the module
-
Make sure that the module is set to ONLY connect to 4G LTE networks
-
Make sure that the APN of the module is set to 'sakura'
So, i am using Arduino IDE for making serial communication with the module.
(2)I have set the module to LTE only by using the AT Command AT+CNMP
(3) I have set the module APN to sakura using AT Command AT+CGDCONT
But i am unable to enable data roaming I checked command AT+CREG which gives output (0,3) but I want output to be (0,5) So you help me to enable data roaming to make AT+CREG to (0,5) i have attached the sim module manual too.https://www.waveshare.com/w/upload/6/6d/SIM7600E-H-4G-HAT-Manual-EN.pdf
I have Arduino Nano too , so if there is any so;ution using Arduino it would be helpful.
