Hi...are both modules reliable for industrial applications? Have u ever tested these GSM modules by running them for some weeks or months?

[nellynfedejuan]

Great!❤❤ By the way, I wanna ask if it can send message without a Load specifically here in the Philippines. The case is I wanted to inform the receiver using sensor. If the device detects a sense, it will send a message to a mobile phone. I only want arduino to send message and thats it. I am a student and I wanted to include this onto my research device. I hope someone will notice me po. Thank You 🤗🤗
