Question
i have a phone that is 2g gsm 900/1800/1900 compatible, my question is, the place im planning on going to, has only 3g 1900mhz, but offers no 2g, will my phone be able to work in that area? isnt it suppose to be that a 3g network be backward compatible with 2g?

thanks!

Answer
Hi

Actually the technology used in 2G is totally different from 3G. regarding my word, it depends on your mobile phone if could support 2+3G or not.

2G technology is either CDMA or FDMA/TDMA when 3G is WCDMA. one tech-support phones can not work in another networks.

Best,
