Out of 1GB 512MB can be used in both 3G and 4G network while the other 512MB is to be used in 4G network only.

If a user having 3G only handset on Idea Maharashtra or Idea Goa network would recharge with Rs.169 then he would get only 512MB data benefits. This is because the other 512MB can only be used on 4G network which can’t be accessed with a 3G handset.

Additional 100MB 4G/3G data can be availed if recharge is done on My Idea App. So that makes it

1.25GB in Rs.169 valid for 28days for a 4G handset user &
750MB in Rs.169 valid for 28days for a 3G handset user.
