I'm currently with VZW & thinking of switching to Sprint. I love VZW coverage but I have a family plan with unlimited data but my wife & I split so now I have two phones & only use one & pay around 220 a mo. & is getting a bit expensive with just my income so if I cancel one line I have to sign a new contract & don't want to lose my unlimited. So? Is how good is sprints coverage in TX compared to vzw . I live in Houston but travel to West Tx for work so will I get charged for roaming if I get the unlimited everything plan... Thankyou
