Vodafone network in Dehradun is slowest network whenever I have I use data it doesn't work and then everytime I have to reboot my Phone and then it works and it is the problem of every time so I called to customer care of Vodafone and they doesn't response to my call everytime and the network is really really slow and the customer service of Vodafone is worst so I will personally recommend you to not use Vodafone supernet 4 g and use some other network.
