I currently have a Droid Razr Maxx, which, if I understand correctly, can use both CDMA (3G) and LTE (4G) data service. I am thinking of upgrading to a new phone, but notice that Verizon is now moving to LTE only phones. In many of the areas I go for work, I have noticed that I ONLY get 3G service. I am assuming that this means that I'm accessing CDMA service there. If I upgrade to a Galaxy S5 or other LTE only phone, will I not get ANY data service in those areas?
