Erica and her family are Sprint customers who are eligible to upgrade their phones in a few months, but they have a dilemma. In the market where they live, Sprint’s 4G service is the older WiMax network. An upgrade to LTE is coming…sometime in the next year. They have their choice of phones that can use one network or the other, but not both. Yes, this is the very definition of a first world problem, but it’s a gamble. Do they choose faster data now and being forced to use 3G after the upgrade comes, or the other way around?
