I was on the cell that's on top of one of the high-rises in Seagrove, can't remember which. That's the cell with the problem. I could receive calls just fine in Rosemary or Grayton, just not on my home cell. Never had any problem with outbound calls or dropped calls. I missed half or more of my inbound calls, texts, and voice mail.
They sent me an Airrave but I never hooked it up, expecting exactly the same sort of glitches you've experience. Besides, I didn't want VOIP. If the DSL goes down, there's no phone service. Same reason I've still got a real land line.
I have called, emailed, Tweeted and chatted with Sprint for 6 weeks, just about daily. Can't tell you how many hours went into it. It took 3 weeks just to get them to realize that it was neither downtime on the tower nor the (non-existent) 4G upgrade. Their internal organization for taking trouble calls isn't flexible enough to allow them to define a problem other than the routine stuff like a tower that is dropping calls. They also don't have a way for anyone to take ownership of your problem, so you're constantly starting over from scratch.
One of the aggravating things was this: Their network techs checked out the tower, found good uptime, and said "problem solved". So, a person from Sprint calls me to confirm. Can't connect, goes straight to voicemail. EXACTLY the problem I'd defined over and over to them. The Sprint person hasn't even looked at my file, or the lack of a ring-through would have tipped them off. But no, they just leave a message - "your problem's been solved, have a nice day". Equine exhaust.
We went to the Verizon store Sunday and solved the whole thing. It was disappointing to have to do that, because we'd been with Sprint since 1997 and generally had very little to complain about.
Moral of the story - If you're on Sprint and live between 395 and Eastern Lake, you're hosed for now and may be hosed for quite some time, unless someone at Sprint wakes up.
