Networking assistance in Guatemala

we are a service provider specialized in the Telecommunications Field.
We are looking for someone who can support us in buying prepaid SIM Cards.

We have a QoS project that requires being able to make some tests with local SIM cards / subscription. The purpose of our work is strictly to evaluate the quality of services (inbound and outbound).

Please let me know when would be a good time to discuss this subject.

Of course, we will give a compensation for this support.
