BSNL WLL
Handset and general queries

The BSNL WLL mobile handset which I have got from BSNL after getting new connection is very old and bigger in size. The name of the set is YUNDAI CURITEL.

Please suggest me some smaller and good brand handset like Nokia, LG, Samsung, Sony ericson, Panasonic etc. with powerful signal which I can purchase by my own from market and configure it from the BSNL office...

I have few more question&

1. What is the specification/type required in the handset which i can purchase from the market??

2. Is WLL and CDMA phone similar??

3. Can i use any CDMA like tataincom etc. and get it configured from BSNL??

3. How to get internet connection from WLL handset??

4. Is the BSNL Tower (for Signal) of the WLL and GSM mobile phone (like cellone) same??
