MTS is a very poor company with a very poor network they don’t have any coverage in all places of India even the Data Services are not working properly I live in Delhi but there is no MTS network coverage area where I can find full networks of mts they just promote their self but in reality MTS has a very poor Customer team whenever I use mts the called starts dropping the call cuts down while talking so in my opinion use Vodafone as your network never use mts my personal experience
