Has anyone's iPhone ever just stopped working all together out of nowhere?

Question

NEEEEEEEED HELP.

Answer 1

Im in 79707. So to recap my whole case: I upgraded my device using the verizon wireless website. I received my phone and switched my old SIM card from my Droid Razr Maxx HD into the new Galaxy S5. Everything worked fine until the next morning (May 31st) when I woke up and the phone wouldn't turn on. I took the phone to the local Verizon store and they were also unable to turn it on. They issued me a new Galaxy S5 (referred to as phone 2) and switched my SIM card into that one.
With PHONE 2 i was able to make calls and receive calls, along with text and data for approximately four hours. After that, i was unable to use the phone function of the device, but text and data were still functioning. I took PHONE 2 back to the Verizon store where they attempted to hard reset the phone twice, they also installed two new SIM cards at the store. After this they would get the same error, which is the phone just reading "Dialing..." after attempting to make a call. The Verizon associate declared the phone "DOA" and issued me another Galaxy S5 (referred to as PHONE 3).
PHONE 3 worked well, with phone text and data featured intact from when I received it on the after noon of the 31st until approximately 2:30PM on June 1st. I contacted Verizon Tech Support via Gmail phone to attempt the correct the problem. They reset the connection, had me do a battery pull, had me close the "phone" application, and erase the data and catche, then restart the phone. All of which had no effect. My phone is still able to receive texts and use data (even with wifi off) it simply cannot make or take phone calls. all it says is "dialing..." when I attempt to make a call. When other phones call my device it rings once on their end and directs them to voicemail, PHONE 3 does not ring on my end.
I have made sure my old phone is completely powered down.
