Tata Docomo is the very popular mobile operator service.Recently I bought this sim after I rejected my old sim.this sim is best sim I seen ever.i know many people said to me this is very bad sim, bad network . but in my home this sim working totally good. 100rs for first time purchased and I got 100mb net free and charge power 4months all local call 25p/mint
now I use this sim, I am total satisfy about its service.when my power end then only 74rs recharge and I will get 4months 25p/mint.so recently I use this sim and also use in future if they will provide good service as same as right now.
