Vodafone .it’s one the best network for me.I am using vodafone since 6 years.during these years vodafone done more service at less cost.like data, callimg sms, mms etc.Vodafone provide talktime morethan your recharge ( like rc.70 gives 80 and rc46 gives 1gb 2g etc) .
These offers validity is also high.when compared with airtel, idea they provide offer for 1time recharge but its not vodafone.vodafone mpesa also attractive for customers , they provide cashback also in mpesa.their service for customers also very attractive.Overall I vote for vodafone keep it up.
