SIMSHIELD provides groundbreaking bandwidth optimization services for VoIP call termination which uses complex cloud communication technology, voice compression algorithms and tunnel encryption modules to provide high quality voice even in low internet bandwidth. We make it possible to run a call at as low as 8 to 10 kbps data usage which enables a staggering 5 fold call increase with the same bandwidth or internet data usage. Our VPN is compatible with any standard softswitch and all major analog/digital termination devices (gateways). Its ‘self-managed’ feature enables users to reduce cost of having technical or support team as well as reducing the dependency.

An unlimited VPN account costs just $65.00 USD per month.  Save $5 per month with an annual account.
