yes...absolutely
CDMA phones only allow certain sim....and tata indicom is one of them
people usually take CDMA phone for tata indicom and its converse is also true
CDMA and GSM are Radio technologies and mobile Phone is just an Antenna to receive these Radio Signals. Since both the technologies work on different frequency range and has different modulation shemes therfore the mobile phones for both are different.Apart from this 3G tehchnology which is combination of both GSM and CDMA (WCDMA) is compatible with both GSM and CDMA. So a 3G mobile can serve for both GSM and CDMA radio signals.SIM (Subcriber Idendity Module) is consists of Credential for network authorization. Since Both GSM and CDMA technologies has different Authorization functions and parameters hence both SIMs are different. Note: In CDMA technology SIM is often called as RUIM (Removable User Idendity Module).CDMA uses Different Frequencies than GSM. CDMA also does not require a SIM card.Now some companies do provide SIM cards for CDMA connections also, such as Reliance communications and TATA Indicomm in India.CDMA can hold more calls per channel on their towers, while GSM drops alot of calls. That is why people are always complaining about T-Mobile and At&t dropped calls. GSM is used internationally while CDMA is mostly used in the domestic United States. CDMA carriers are Verizon, Alltel, Sprint, Cricket....while GSM carriers here in the U.S. are T-Mobile and At&t.
as we say cellphone is very important for everybody.we can used of gsm,cdma sim in cellphone and depend on your mobile model
CDMA is a type of network that cell phone company's use. There are to meager types of networks that are used CDMA and GSM. Cell phone are usally made to work on one or the other network. The Iphone is GSM and Verizons Dare is CDMA but some phone can work on both like the new Blackberry storm.
does cdma work in egypt
The full form of SIM is Subscriber's Identity Module. The SIM card is used into mobile phones to make calls, send messages, use internet. There are two types of SIM card. One is GSM and another is CDMA. The full form of GSM is Global System for Mobile communication. The full form of CDMA is Code Division Multiple Access. The CDMA Technology is superior than GSM.
Tata the Indian Enterprise used the slogan - Improving the quality of Life...
same pattern becaus same gsm plan launch and cdma and tarrief is near about equall and both company pay the vsnl and both is used in dcn and fiber opticle pair
No, T-Mobile is GSM and Verizon is CDMA so you can't switch between those two networks. Unlocked T-Mobile can be used on AT&T though.
Probably not. The Sprint Nexus S is a CDMA device. Simple Mobile uses GSM devices. An unlocked Nexus S that can run on GSM networks will work however.
UIM is CDMA sim card which is used for mobile services like GSM. It can use with netconnect for internet surfing.. Enjoy.....
3G is Radio technologies for Wireless mobile networks. Its an evolution above GSM technology which is widly used all round the world. In short We can Say that 3G is combination of various Mobile technologies like GSM and CDMA. The main advantages are 1. Convergence of GSM and CDMA as a single entity 2. Better Bandwidth and Security Aspects.
- CDMA800 (low band) is at freq 800MHz whereas CDMA1900 (high band) is at 1900MHz. - TX power of CDMA800 is lower than the CDMA1900.
