Is there a way to save my uncle from jail??

Hi,

    I am coming straight to the case that has occured with my dear uncle. Recently a group of Theives selling goods worth of 3 crore selling for only 50 lakhs was caught by police. The arrested group member when inquired by police for their Boss gave police a cell number. When police got name and address of person on whose name the card is registered they found that he is the resident of my Uncles village.

    they caught that person. Now the person is saying that he never bought that SIM card. The SIM card is activated from my Uncles LAPO card. that means the SIM has been sold by my uncle. Now the person whom police has caught is for sure not guilty and innocent. That means the SIM card has been sold by mistake to some other person by my uncle (By mistake- coz my uncle is really a truth speaking person and never does illegal acts and has good repute in society). If the Boss of the thieves get caught and says that he has bought SIM from my uncle, he will get jailed. 

Please guide me in this matter:

1) what should my uncle say to police? has he sold or not sold the sim card? coz he really thinks he never makes mistake in attaching documents.

2) can he take a anticipatory bail in this case?

3) what is the maximum punishment he is liable for?

4) If the innocent person who is caught says that he has bought sim from uncle and then it got lost and received by the boss of theives then will my uncle be saved?
