Hello Guys,I am MTNL user from last 6 months. Initially I have taken MTNL's DSL Unlimited 999 Plan & I was staying at some place in Mumbai. Now recently I have shifted to some other place in Mumbai & opted for MTNL's DSL Unlimited 599 plan. Few of my family members still stays at same place & I visit there frequently. Now my problem is that can I use these two connections form either of the places? If yes than how & if no than why?
