My phone frequently loses it Cellular connection. I can reconnect by turning Cellular Data off and then back on. I have had my iphone 6 for six months, but this problem started about two weeks ago. Any help would be appreciated.
Have you checked to make sure that the SIM card is properly seated in the holder? If it is, and since your iPhone is still under warranty, you should take it in for a Genius Bar appointment at the nearest Apple Store, if it's close enough. If the problem is hardware related, it would be fixed at no cost to you. If an Apple Store is too far away, an authorized service centre is the next best choice.
