Its been more than two weeks that I am using it, it is an awsom device with a great speed of more than 3 mbps and connects more than 30 devices at the same time, and it is having a good battery backup which is enough for the whole day to remain connected to the internet, it is very slim in design and can be carried easily, any 3g phone can be connected to it and can also make voice calls from this device, it is also very cheap it bought it for just 1999 only. Any jio sim can be connected in it and there are many support centers for any problem.
