I used this T24 sim 6 months back, in Hyderabad big bazaar I purchased some products that time there given this sim free so I used this, main problem with sim was signal mostly I never receive signal for this sim, and there is T24 recharge centers we have to recharge with tata docomo recharge, and there is no customer care center if we face any problem with sim nobody can response for this network, so please guys don’t use this sim if they given free.
