The SIM card is so you CAN easily change your identity / phone. Without a SIM, how does the network verify your identity? A simple username and password are not as secure, and tying your identity to your phone is exactly what SIM cards were introduced to avoid.
- latch 15y agoA username and password is secure enough for things more important than this.
- jasonlotito 15y agoNo. They aren't. That they can be used as such does not make what you said true.
- bnegreve 15y agoHum ... like what ? It is quite critical, someone with your username/passwd would be able to call for several hours without you knowing it.
- latch 15y agoA lot of banks don't support two-form authentication. A lot of online merchants keep credit card information on file and allow for quick check-outs.
