Frequently Asked Questions
Frequently Asked Questions:
Q: Can I update the firmware of the Sigma Card?
A: Yes, the firmware is completely updateable; we provide a tool and the newest firmware for FREE. Check our download section on our website for updates.
Q: Do I need a special dongle to use the update tool?
A: No, there is no special dongle needed, only a smartcard / simcard reader!
Q: What smartcard or simcard reader do I need to upgrade the firmware of the Sigma Card ?
A: Any USB or comport based 3.57 MHZ clocked Phenix or Smartmouse smartcard reader will work. You can purchase from our online store.
Q: You claim your product is MUCH faster than others, can you explain why?
A: Yes, we can, other cards base on forwarding traffic, means they are between the phone and the original card, so even if they make full use of the speed enhancement they will need to collect data and than send the data again and this applies for both directions... - so even if they make full use of the speed enhancement we will be 50% faster than them
Q: You claim your product is better than others on the market, can you explain why ?
A: There are many similar products on the market that claim to be as good or even better than the SIGMA, they all base on forwarding traffic between the phone and simcard - that is the main difference between them and us.
A: YES, you loose performance (speed) as well as you open the door for a lot of secondary problems because of frame or timing errors ! Even if those products are looking to work well in the beginning a lot of issues can arise later !
Examples:
- Phones that restart because of bad or incomplete implementation of the protocol
- Freezing phones because of bad or incomplete implementation of the protocol
- Phones that loose connections because of bad or incomplete implementation of the protocol
- Certain features of the simcard are not working well or not at all (GPRS, 3G, Edge...)
