What phone do you have? The price varies by phone. Did it break physically from a drop or something or did it just stop working? If it has just stopped working and you have had your phone for less than one yyear, you can use the warranty to get it replaced/repaired.
If it comes to you needing to pay for a repair, you should search for cellphone repair shops in your neighborhood and online and get quotes. If you want a new phone and use your tab you will have topay off your tab. usually it gets put on your next bill or you can pay it ahead of time and then use it.
