I am looking for international postpaid SIMS for calling. For demo initially I just require 1 SIM. I will deliver a device also. You will have to put that sim in that device and use it for call masking. Payment will be made monthly for sim and for monitoring. Once the demo is passed I will buy 10 to 20 more sims and you can be my partner. Payment will be made monthly and handsome also
Note: I will handle everything remotely you just have to change the sim if it is blocked and keep checking the device that it doesn't turn off so it's a easy task.
