3g is a type of mobile network that supports broadband internet access & digital clarity of voice along with features like Video Calls & other Value added services like Live TV on phone.
High Speed Packet Access, or HSPA, is a cellular network data standard. It is the fastest network speed available using 3G technology as defined by the Global System for Mobile communications Association, or GSMA. HSPA requires compatible hardware in the cellphone and the cell network, so only some phones can use it and only when within suitable cellular coverage.
First of all, there is 2G (or EDGE), 3G, 4G, or 4G LTE. Many people just call 4G LTE 4G because regular 4G seems more like 3.5G. Keeping up? AT&T's 3G network is known as HSPA and their regular 4G network is known as HSPA+. Because the iPhone 4S supports HSPA+ but not LTE, it is a 4G phone, but not a 4G LTE (real 4G) phone. Luckily all this confusion is over now that the iPhone 5 supports LTE.
When you are in a Vodafone 3G network area & if your handset shows "3G" or "H" on the top of the screen next to the network signal bars means that your phone is 3G compatible & you can use the services. You must also ensure that the phone settings are not set to '2G only'. WCDMA or R99 devices are 3G devices but support low 3G speeds upto a max of 384kbps HSPA devices are high speed devices & support anything from 3.6mbps to 7.2mbps depending on the device. We recommend that a user should upgrade the handset from WCDMA to HSPA for better speeds & experience
First of all, you need a 3G supported handset and a 3G supported Sim card (some 2G Sim cards also allow to use 3G networks) then activate 3G by contacting customer care of the SIM's manufacturer. Then you may make use of HSPA or other network connections to connect to the internet.
The Nexus S is a 4G capable phone. This means that it is capable of running on your carriers 4G network. However, it can also fall back and run on the 3g or 2g network as well, so it supports them all!!
the easiest way to disconnect from the 3G or HSPA network is to get the application for the market called "APNDroid." Once downloaded you can check off "Disable all APN's" which will turn off the network connection. Hope this helps, Joweejaw
You can access 3G data if you are in an area where there is a tower that supports 3G. All about the coverage. you can call and ask your cell phone provider if you get 3G coverage. Often it will even be displayed on your phone as 3G or HSPA.
AT&T is a network and they do have a 3G network. They are not considered a 100% 3G network because they have a lot of different options.
The AT&T USBConnect Momentum 4G is is one of three modems available that can connect to AT&T's new, 4G LTE network. The device only support AT&T's 3G HSPA network and its new 4G LTE system.
You need to have a GSM/HSPA cellphone. you have to put a sim card inside the phone. But it's not all phone will work on the koodo network because it's a new network, HSPA.
No we can't use different network 3G sim in Vodafone 3G sim.
The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
