Okay, so at my work we have someone that pretty much needs a portable hotspot with them out in the field. We'd rather use a phone's hotspot instead of a dedicated hotspot device, for convenience and cost. Currently they have a Galaxy S6. With the hotspot enabled, whenever they receive a phone call(not answer it, receive it) it cuts out the hotspot. I tried putting the phone in Do Not Disturb, but all this does is silence the call. I tested on my personal iPhone 6+ with Verizon. When in Do Not Disturb it sends the call straight to voicemail, no call pops up on the screen at all. However, I don't have the hotspot feature. Essentially, what I need to know is this. Can anyone using an iPhone on the Sprint network with the hotspot feature, tell me if you can use the hotspot without calls cutting it off? Can you do this using Do Not Disturb? Does it matter if you are on 3G or 4G? Someone else here says their sister who has an AT&T iPhone is able to talk on the phone and use the hotspot at the same time.
