One SIM for all the networks allows you to remain connected at all times.
No single network has flawless coverage or service and so when it comes to complex or mission-critical connectivity solutions, basic SIM cards leave you exposed. You need the best connectivity possible, no matter where you are.
Why do I need a multi-network voice SIM?
If you rely on cellular coverage to communicate using voice, text or data and your network is not giving you a signal, you have a significant problem. At V12 we offer a solution to that problem with our multi-network voice SIM.
