Verizon Wireless coverage in 18034 zip code / Center Valley is very poor - expect at least a 50% probability of being unable to receive or make calls in this area and also a 50% probability of a call in progress being dropped in this area. Using the same phone, as soon as I go over the hill into Allentown, or over the hill into Bethlehem performance goes from poor / abysmal to absolutely reliable so its not my phone. Numerous conversations with Verizon reps have taught me that the reps you will talk to have no technical knowledge and that you have about a 1 in 10 chance of being taken seriously. On rare occasions your problem is passed on to to folks who can speak knowledgeable manner - when this happens cellular performance improves (usually takes 1 to 2 days) and they actually call you back to confirm this - problem is the performance improvement seem to last for 3 to 6 months then it degrades again - problems are independent of season of year, weather, and trees having or not having leaves.
