SIM Card overlay…quick…what comes to mind? I bet….eh…nothing.
Here is why this technology is so cool and so important to VelaTel. In keeping with their 4G carrier insurgent strategy—SIM overlay is PERFECT. Most every digital device—phone, tablet, Mi-Fi card or dongle has a SIM card (Subscriber Identity Module).
The SIM holds personal identity information, cell phone number, phone book, text messages and other data. It can be thought of as a mini hard disk that automatically activates the phone into which it is inserted.
