Hello,
My name is Rui Pimentel and I have more than 10 years of experience in development of all kinds of IT applications.
I completely understand what you need, and I can set up a VM for you with a 4G connection tethered from my phone. I have multiple MEO cards I can use with 200MB of data to use, and I won't charge you for the data, only the setup.
I'll be waiting to hear from you, can set it up quickly for you.
Thanks,
Rui Pimentel
