Mcent is very goog app that gives free talktime recharge. the referal program is so good for the users. I also earned rs1200 from this app. some a few days ago it gives rs 200 for refer but this days it is reduced at rs 40. I think the referal amount should be increased to rs 200 as earlier for increasing app users. some oter features like messaging to other mcent user is so good.
Now you can send message to other mcent user easily without any additional cost.
