Hope someone can help me. I have searched through the Forum, and have not found an answer.
I have developed 3 products using the GR64, a GPS tracker, Alarm Auto Dialer and people counter, all using SMS and GPRS to communicate with the owner, and post data to a website.
They work a treat, only problem is to switch between different SIM providers, we have to change the Service centre number and Access point name within the script, (or use an NVR setting). Is there a way the module can request these from the service provider the same way a mobile phone does?
How does everyone else set the service center number and APN?
Thanks in advance
