HMMM .THE LARGEST 4G PROVIDER.NETWORK.I WOULD RATE IT 4 BECAUSE ITS BEEN USEFUL AS USED A LOT VOICE CALLS AND DATA.GOOD SPEED DEPENDS UPON THE LOCATION U ARE AT
GIVES SUPER SPEED SOMETIMES BUY GETS WEAK AT SOME PLACES .BUT SPECIALLY U GET GOOD NETWORKS WHILE TRAVELLING ON HIGHWAY OR TRAIN.LIKE THIS PRODUCT AS USED IT FOR FREE AND QOULD CONTINUE BY PAYING 99 + 303 .FOR RECHARGE CHEAP AS COMPARED TO OTHERS .I WOULD RECOMMEND THIS SIM TO MY FRIENDS HAVR USED FOR MORE THAN SIX MONTHS FOR FREE.GOOD ONE
