I am using reliance's Jio sim since I have buyed Lyf flame 8 last month. It come with Jio preview offer given by reliance Jio. The internet speed provided by Jio is just amazing, I have never surfed so fast before using reliance Jio's service, It's true 4g. Free calling, unlimited sms, unlimited data all are working good. The only problem sometime occurs is call drop, specially calling to idea. Otherwise so far is so good and the time limit of use is also sufficient enough. Now reliance Jio's offer is available on all 4g smartphones.
