How can I change registered card from CDMA to gsm in Samsunggalaxy ace duos?
you use unlock att .com they did my iphone there but i noticed they do samsung phones too
Why do CDMA phones doesn't require sim cards?
The network operator has all the serial numbers of their phones in their data base. The serial number is also written on the phone themselves under the battery. For whatever reason, CDMA carriers are too concerned about what phone you're using unlike GSM carriers that don't monitor your every move. In GSM the carrier is only concerned about the SIM card and not the phone. In CDMA the operator doesn't have a SIM to track, so they worry about the phones themselves. CDMA is a very restrictive, oppressive technology. They lock down their phones to the carriers so you can't take your phone to a different carrier, unlike GSM. GSM is the way to go if you like freedom.
Can you unlock a phone that doesn't have a SIM card?
You should have no problem using the BSNL modem with any Sure BSNL modem ( likely to be ZTE manufacturing) may be used with any other broadband connection and the same is applicable for other companies too.
What is the wavelength of a blackberry?
By wavelength do you mean the wireless frequencies? If so this is not a brand dependent thing, it is carrier and phone model dependent. There are Far too many variables to list everything here but you can find the info you are looking at here: For GSM Band Cell Phones Or For CDMA/UMTS Band Cell Phones

I had that too and the correct answer is spectrum.

What is spectrum in telecom?
Wireless communications make use of the radio portion of the electromagnetic spectrum. Simply put, telecom operators send and receive signals at various frequencies to enable communication. This radio spectrum contains only a limited number of frequencies. Signals can be sent on different frequencies all at the same time, however, if frequencies are the same or too close they can interfere with each other. As the number of frequencies is limited, they need to be allocated to different service providers. Therefore, spectrum is allocated for various communication purposes world-wide. Is spectrum being given free to telecom operators? Contrary to popular perception, spectrum is not available for free. Currently, spectrum charge has two components - the entry fee charged is inclusive of one-time spectrum charge, and an annual spectrum charge based on a percentage of the Adjusted Gross Revenue (AGR) of the telecom company. The percentage of annual spectrum charges for GSM operators, for instance, varies with spectrum usage. Currently, the ceiling for annual spectrum charge is 6% of AGR. Trai, though, has recommended that the ceiling be lowered to 4%. Now, Trai's recommendations only say that there will be no one-time spectrum charge for allocation of IMT-2000 spectrum (meant for 3G) for existing service providers. The regulator has explained that the allocation to the existing operators should be viewed as extension of 2G spectrum allocations. However, a contrary view is that spectrum is a scarce resource and that additional allocation should be priced. Regards, Kanak New Delhi

Is the visible light spectrum between radar waves and xrays?
No, the visible light spectrum falls between infrared and ultraviolet light on the electromagnetic spectrum. Radar waves have longer wavelengths than visible light, while X-rays have shorter wavelengths.
