Most telecom companies use a variety of 'carriers', the companies who own and manage actual networks that your calls are made through. Many calls go through a variety of carrier networks before they reach their final destination.
maxSIM™ uses advanced VOIP (voice over Internet) technologies to send and receive calls through the state-of-the-art maxSIM™ global network.
This allows us to offer the most competitive rates. Furthermore, because maxSIM™ is dedicated to international travellers, it focuses on providing high quality services for such, at realistic affordable rates.
This is as opposed to conventional mobile service providers who take the opportunity to make high margins via roaming charges in order to offset the less attractive margins they make offering domestic services which are more competitive and more openly regulated.
