If you wish to change your handset to LSI 110, then you can definitely go for it at the cost of Handset Change charges (800/- probably + other formalities) and the DATA Cable for your new set.
The Peak R-Connect speed would be arround 152kbps(momentarily) with ocassional auto disconnect due to dormant connection.
Further the set LSI 110 is just like a cordless, but its handset feature is not liket that of other LG Mobile sets.
