Well, this is the best sim nowerday. And as it ig givimg free calls forever it is doing a great job.
The network coverage is good. And it is quite a lucky things that u get 4GB of 4g data every day.
Now come to its speed. The speed of the sim is highest at the time when less people are using it, means at the night after 1am. If you want to download a file of 1gb or higher you can start it after 1am. And in morning you will find it completed.
I say use this sim till it offers you free Internet, video call, phone call, sms. And from 1 January when it starts it services for cash. You decide and compare prices from other 4g network and use.
Thanks. ??
