I m using this uninor network from last 3 month just for the cheap net pack and call rate I switched to this network from tata docomo but all went wrong its 2g speed is so slow that you can even open the page.Getting 4/5 call from company many time I reject the call but by chance I picked up the phone some service get started automatically.If u done a rechage of 100 and not done a single call from that as using this phone for mobile net and end of month I came to know that call tune as automatically assign and daily rs 1 is deducted from my account.I sugget dont buy this cheap N/W buy whichever you want but dont go with uninor.There is no problem in nwtwork covergae problem is that they will start the services without informing to you when u see the balance then you will came to know about the service And if you are planning to buy for internet, dont buy just bu seeing its monthly rest or tariff because its speed is too slow.
