No. A 4G phone typically is compatible with 3G networks, especially since 4G networks are not entirely established. 3G however is a lower generation technology that was created prior to the 4G so there just isn't a way to have the technology already in place for the newer.
NO
Yes, it is backwards-compatible.
No, This phone only supports GPRS(2G) and EDGE(2.5G) and have no support for 3G and 4G LTE.
3g and 4g are terms to define the internet speed on a smartphone. 4g internet speed is slightly faster than 3g and 4g service is a little more than 3g service.
3G and 4G are types of internet connection. 3G is older and slower than 4G. While 4G is faster, there are also many variants of it, it's not as much a standard as 3G is. 4G is also not as widespread yet as 3G is. If you need access to both, you'll need a phone with both 3G and 4G radios built in.
Yes 4G is better. The download speeds are much faster on the 4G compared to the 3G. You will also be able to see streams and videos clearer on the 4G compared to the 3G.
4G can get internet underground much faster than 3G can, and you can e-mail on an underground train.In a simple answer, both describe the speed of your Internet. Thus, 4g is faster than 3g.
No a 3g phone cannot be modified to run on 4g. The reason it cannot be modified is that the 3g runs on a different operating program than the 4g does.
once 4G is as popular as 3G
4G can get internet underground much faster than 3G can, and you can e-mail on an underground train.In a simple answer, both describe the speed of your Internet. Thus, 4g is faster than 3g.
4G and 3G are just the speed of the internet on the phones. 4G is slightly faster than 3G. I would recommend just waiting for your contract to end before buying another phone.
Unfortunately your phone will not work with the 4G service. You will need to buy a 4g phone to work with the 4G service. Some 4G phones will work with 3G service, but not vice versa.
Possibly, when at&t upgraded to 3g it was just them increasing their network speeds alot like what Verizon may do and seeing as all it runs on 3g it should be able to do 4g. Verizon is promising a 5mbps to 10 mbps increase just to give you an idea verizons current 3g is around 3.5mbps
