SIM 800L expert wanted

Hola, Puedo tratar de ayudarte pero necesito mas informacion sobre tu projecto actual y de esta manera ver si es algo con lo que ya este familiarizado, tengo experiencia con el SIM 800L. Cualquier duda me escribes, Saludos John

Hello. I have a large experience in SIM 800/900 modules. Can you provide a link to the GSM library that you will use for your project? I will send you a code that will be compatible with that library

Hola. En primer lugar me gustaría saber que tipo de microprocesador estas usando para controlar la Sim800L. Tienes el codigo editable para modificar los comandos? . Si es así podemos usar un comando AT para modificar que operador va a seleccionar el microprocesador. Saludos Darwin Pardo

Hi! My name is John Stratakos, I'm a professional Arduino developer with great hands-on experience. Please see my profile and reviews for more details. For your project, I would recommend two ways to solve the network issue. 1) Provide me with your existing code to modify it so that the modem selects the desired network. 2)Provide you with the appropriate AT commands to insert them before the network registration. After that, you can test the code and pay me. Feel free to contact me for further discussion of your project. At modems can become really nasty, I know. Best regards, John

I want to know more about your issue. Can you please elaborate ?
