Yes, phones with WCDMA (Wideband Code Division Multiple Access) and multi-band GSM (Global System for Mobile Communications) typically use SIM cards. The SIM card is essential for connecting to mobile networks, allowing users to access services such as calls, texts, and data. Both WCDMA and GSM technologies rely on SIM cards for user identification and authentication on the network.
No, 3G GSM phones cannot work on a WCDMA network, as they use different technologies. GSM (Global System for Mobile Communications) operates on a circuit-switched model, while WCDMA (Wideband Code Division Multiple Access) is a packet-switched technology. Although both are part of the 3G family, they require different hardware and protocols, making them incompatible with each other. To use a WCDMA network, a phone must specifically support that technology.
There is no such thing as a CDMA SIM card.CDMA is a technology which doesnt use SIM cards.And WCDMA is evolved from gsm and uses SIM cards for 3g.
GSM was created for cell phones in the early 80's. GSM allows you to swap out SIM cards to change your cell phone number, which is an extremely convenient feature.
In short, no. WCDMA is designed to enhance GSM networks, even though it's technology is similar to CDMA, it uses different language.
AnswerYES !!! GSM Phones, CDMA Phones will work in India
a phone with these two facility can work in GSM with sim card and can work without sim card in cdma mode
The short answer is no. Boost's newer iDEN phones do use a SIM card that can be used in GSM devices for international roaming but they will not work in GSM devices in the US. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
You cannot use a WCDMA phone on a CDMA network. Wideband Code Division Multiple Access (WCDMA), despite its name, is different from and not part of Code Division Multiple Access (CDMA) networks. WCDMA is one type of 3G technology and is an extension of Global System for Mobile Communications (GSM) networks.
i need materials too thta how simulate inter system handover between wcdma to gsm.......
Samsung phones that can support GSM 850/1900/ 3G 1700/2100 are the ones that will work in America. Also, make sure that the phone is already unlocked so you can just insert any American GSM SIM cards.
The phones cellular radio would have to be compatible with the network you wanted to use it with, plus unlocked so that you can connect it to what ever network it's compatible with. T-Mobile uses GSM 850/1900 and UMTS/WCDMA 1700/2100 A quick google search resulted in this: Other cools specs the NEC 931N Slider features is the 1Seg TV tuner and GPS function. There is also Bluetooth Connectivity, Infrared Connectivity, WiFi connectivity, supports microSDHC cards and WCDMA and GSM networks. It might work, but you'd have to check the frequency range the radio operates in. GSM is just a transmission standard and can operate on any radio frequency.
Nearly every manufactturere produces at last one GSM cell phones. You can find GSM cell phones like the LG GT365 ,or the Tmobile sidekick
