If you are having a reliance sim than you should have an alternative sim with you . As it promise, but do not provide good facility. I used its sim but my personal is not good . it sometimes do not make call to costumer care and many times they put off the call . many time the signal get weak any where and in usual its signal is weak .
They cut money from your account without information and do not take up call on calling and after 24 hour take call and argue.
DO NOT GO WITH ITS GADDU OFFER as by my personal experience an flash massage shown . after recharging first they given me extra balance and then after 7 days they cutted the balance back . on contacting with costumer they told that due to technical problem they proceeded an extra balance on it .
I strongly recommend that do not use this sim as an alternative to.
