UMTS (3G) and EDGE are rival technologies just like CDMA and GSM respectively. By launching pairs like W850/W830 and K800/K790, what SE is doing is offering you a choice of which data technology you want to use instead of trying to cram more technologies into the same phone. When you are with a service provide, you are going to get either 3G or EDGE, not both at the same time.
SE gives us technology which works flawlessly, unlike the leading Finnish manufacturer who tries to give you the impression that it is giving you a feature-rich handset but fails miserably in everyday use in terms of implementation of the technology. It tries to give you impression of being Master of all Trades but actually is Jack of None.
So I hope this stops the endless ranting about no 3G/no EDGE and let us applaud SE for being practical in their application of technology.
EDGE = Enhanced Data rate for GSM Evolution or enhanced GPRS, 115 Kbps in data speed, it could be considered as 2,5g
UMTS = Universal Mobile Telecomunication System, 384 Kbps in data speed, it is the famous 3g
HSDPA = High Speed Downlink Packet Access, now with speeds of 3-4 Mbps, this is the 3,5g
The main difference between W850 and W830 is the UMTS and videocall camera in W850, while W830 only has EDGE, except for this both are exactly the same phone.
Please suggest which one is better w850 or w830..i think w850 is more advanced as it also has 3g technology..please advice
NOT a cheaper version of W850. Just some diff features. And only for some countries. same price. much rather go for W850
if se have taken k790/800 and turned it into slider then it would have been the best phone to buy.
And who was to say that Nokia is the ONLY manufacturer whose models look the same... :P
If SE is unable to put 3G & EDGE into the SAME phone, one can hardly say that they are innovative or professional... ;)
ma god , i just luv the sonyericsson more and more each day , this phone just seems to be the phone of ma dreams , but ma god will it be cheaper than the w850 or what ???
