OLD AND EVERGREEN JOKE OF R.K.LASKHMAN ON WHY HE HAS 5 PHONES ( NO MOBILES THEN )

On one phone, you can hear but cannot speak. On the second, you can speak , but cannot hear. On the third phone, you can neither speak nor hear. The fourth phone occasionally works. Hence, the fifth phone. I hope that the national telephone operator BSNL will make this joke obsolete. The joke really applies to others in a different sense, call drops, lack of connectivity. Sometimes, pre-paid sim works better than post paid. In some areas, bsnl is better than air-tel. Within Air-tel, post paid works better than pre-paid. Calculate the number of sims you should have.
