IPhone 4 does not make or receive calls/text at a location it used to.HELP!

Question

I started experiencing this sometime last week. It does not make any sense to me so I ask you. My phone does not make or receive phone calls and texts while I am at my workplace. It had worked find from when I got the phone (Late August) through January. If it stopped working completely I'd figure it was a dead zone or something, although they do not just pop up out of nowhere. But it works sporadically. Like if i got to send a text maybe 1 out of every 4 will work, same with receiving them. And this is the same with phone calls. I will receive a call, get through maybe 15 seconds of it, then the call gets dropped. Then for the remainder of the day (as I do not use it much during work) it will not receive a call, it goes right to voicemail. I have tested this by repeatedly calling my phone from my work landline. It rings fine on that end, so others wouldn't suspect I am having an issue, and goes to voicemail. I left a voicemail and my phone did not alert me to it for over 10 minutes (it never told me I had a missed call) During this timeframe I also attempted to make phone calls from my iPhone, they would not ring, it would immediately drop. But again, it is sporadic. So after 5 or 6 times of attempting making phone calls one goes through. I had made an appointment at the Apple Store the first day that this happened but once I was on the road to the store I got all my texts, voicemails, pictures that I had attempted to send earlier, so I thought it pointless since I had no real proof of this happening. But now it seems to happen everyday, it just happened which prompted me to write this. Again, its only at work, and only recently started happening. There is no cell tower issue, everyone elses phone works here. I have turned off the phone, both a soft and hard reset, reset network setting, turned off/on 3G, Cell Data, taken out the SIM, moved it, etc. Everything short of getting another phone, but it works perfectly fine everywhere else. Any ideas???

Answer 1

I ended up taking my phone in to the Genius Bar, but we were unable to diagnose the problem. The genius said she had never seen anything like this before. We tried everything to figure out if it was hardware or software related, but never concluded anything. Instead of paying >$150 to fix/replace, I bought the iPhone5. iPhone5 is amazing. Maybe it was fate.
