Since she is really into her phone, would she read on another electronic device?  At her age, she will read if she finds something she is interested in.  Help her find books that are interesting to her.  Take her to a library and see what she looks.  Most libraries have a computer that patrons may use to find interests without having to ask someone.  If you are paying for the phone, I don't see anything wrong with putting the phone to rest an hour before bedtime so she has the opportunity to indulge in the books she has available.

At the age of teen most of children take the reading as a burden only. Only parents can teach them how to read the books in an interesting manner. Children also learn how to deal with the social problems and negative consequences. Attend different seminars with your children. In this way, parents play an important role for developing reading habits in their children.

Introduce your daughter to the creator Jehovah God, when someone learns the real truth of our existance, it gives us the yearning to want to know more which in turn puts in us, a desire to read. Many of our young ones (some age 3 and 4 years old) are at a third grade reading level and they really enjoy reading and learning about of creator's near future plans for those who follow him closely. There is no better solution on this planet then to turn to him. John 17:3 says "This means everylasting life, their taking in knowledge of you the only true God and of the one you sent forth Jesus Christ". There you have the keys to everlasting life, which will require reading and taking in knowledge of our creator. I hope this helps you.

Reading is a skill that needs to be practiced regularly, especially in the teen years.  Without practice, a teen will not continue to develop the vocabulary skills and comprehension skills necessary for higher level reading activities on tests, textbooks, high school and college coursework.    During those teen years the media and electronic gadgets, friends and lots of drama - start taking over.  It is important to continue the routine of reading throughout the school year and summer too.  

Try Audiobooks.  Download some books onto your daughter's ipod and have her listen each evening in bed until she gets drowsy and tired.  Audiobooks are a fantastic way to strengthen those auditory skills plus gain vocabulary and concepts at the same time.

Read a book together and discuss.  When we adults read books we enjoy, we like to talk about them.  After reading a book, we don't necessarily want to write a summary, book report or make a project of it.  We just want to discuss it with someone else.  Look interested in what your child is reading and ask questions and have your daughter tell you about it.  Laugh with your daughter about the funny parts or cry together about the sad parts.  Help her feel good about reading.

Go to a play - yes the kind in the theater that is also a piece of literature.  Read the book together before the play and then see it live!  Check out all your local universities and community colleges.  They have fantastic plays and very reasonable prices.

Find an author that your daughter likes and stick with it.  If your child loves reading the Twilight series, then you have found a writing style which stimulates her interest.  Go through the entire series.  Don't worry if she is reading below grade level - she is reading for pleasure and for practice.  Also remember, just because you loved a certain author or series when you were a kids, this doesn't mean that your daughter will love the same books you did.  Browse the bookstore or library and find the newest, most modern series.  Usually these books contain language and themes to motivate the most reluctant reader.  Also keep in mind that not everything needs to be a history lesson or educational lesson.  Even if the book is NOT educational at all its OK.  She is reading.  That includes Tiger Beat and other Teen Magazines.

Hope some of these ideas helped you.  Good Luck and enjoy your time reading together!
