[iMore Question]

I am having problems using my apps like GPS and Uber while talking on the phone or if someone calls me. How can i use data and make telephone call at the same time on my sprint iphone 6 plus?

I could be wrong, but I don't recall Sprint supporting simultaneous voice and data transmissions.
