Wakuu nisaidieni. Je naweza ku2mia cdma line kwenye nokia 6720c ambayo inauwezo wa 3.5g hsdpa 10.2 mbps. Na cdma 10.2 mbps. Simu ni mpya ya mwaka 2009 mwish0‹2ni?

Mkuu, Simu yako haina uwezo wa kubeba line ya CDMA,kwani simu yako imetengenzewa kwa kutumika kwenye mitandao ya GSM.

2G Network GSM 850 / 900 / 1800 / 1900

3G Network HSDPA 900 / 1900 / 2100 HSDPA 850 / 1900 / 2100 http://www.gsmarena.com/nokia_6720_classic-2686.php#

Mkuu una maana CDMA ipi? CDMA2000 au WCDMA, kama una maana ya CDMA2000 kama ya Zantel au TTCL basi hiyo simu yako haiwezi kutumika, ila kama una maanisha WCDMA basi waweza kuweka line ya Zantel, Tigo, Voda

Asante

Nadhani itakuwa vizuri ukisoma soma soma hizi terminological terms ujue zina maana gani

Global System for Mobile Communications (GSM, around 80–85 % market share) and IS-95 (around 10–15 % market share[1]) are the two most prevalent mobile communication technologies. Both technologies have to solve the same problem: to divide the finite RF spectrum among multiple users.
TDMA (Time Division Multiple Access-underlying technology used in GSM's 2G) does it by chopping up the channel into sequential time slices. Each user of the channel takes turns to transmit and receive signals. In reality, only one person is actually using the channel at a specific moment. This is analogous to time-sharing on a large computer server.
CDMA (Code Division Multiple Access-underlying technology used in GSM's 3G and IS-95's 2G) on the other hand, uses a special type of digital modulation called spread spectrum which spreads the voice data over a very wide channel in pseudorandom fashion. The receiver undoes the randomization to collect the bits together and produce the sound.
For comparison, imagine a cocktail party, where couples are talking to each other in a single room. The room represents the available bandwidth. In GSM, a speaker takes turns talking to a listener. The speaker talks for a short time and then stops to let another pair talk. There is never more than one speaker talking in the room, no one has to worry about two conversations mixing. In CDMA, any speaker can talk at any time; however each uses a different language. Each listener can only understand the language of their partner. As more and more couples talk, the background noise (representing the noise floor) gets louder, but because of the difference in languages, conversations do not mix. .....

HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. It is an evolution and improvement on W-CDMA, or Wideband Code Division Multiple Access, a 3G protocol. HSDPA improves the data transfer rate by a factor of at least five over W-CDMA. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps (megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA. ......

NAdhani it all depend in Provider( Simcard provider) anatumia Teknology gani but Nokia 6720 ina support WCDMA
