The inability of both AT&T and Sprint to provide a reliable signal to customers who live and work in Center City Philadelphia high rises is appalling. Whether in my 25th floor office or my 23rd floor home, my Sprint service is constantly dropping calls, having no reception, and draining the cell phone battery like mad. My prior AT&T service was no better. There should be sufficient towers within the city to serve higher levels in buildings. There clearly is not.

It is rare that you would ever get reception in Center City with Nextel, which in my personal opinion is dumb considering that downtown Philadelphia has the highest cellphone usage in the City. Nextel needs to fix this problem... immediately!

Dead zone, Wynnefield Rd is dead from Belmont Ave to Cardinal Ave. Just hang up and wait!

reception is fine. but NO CALLS GET THROUGH. sometimes I have to dial 7+ times to reach someone, and texting is a nightmare of holding the phone in my hands and constantly resending mssgs over and over. lately it's been especially bad, dropped calls and network failures.

Clear signal, no dropped calls... even works in my basement. Verizon is pricy, but worth it in my experience.

I had Sprint before and it was terrible--constant dropped calls. Verizon reception is fairly good in my apartment and all through Center and Old City.

Terrible reception with numerous dropped calls. Frequently lose signal while talking to people. Cannot get any reception in my own apt.

Nextel has been and remains the worst of all carriers. Every call that lasts more than two minutes gets dropped and that's standing OUTSIDE! Inside a building... you can forget about it. Just wish they would get the message and upgrade. I'm leaving Nextel after 5 years... maybe if more people jumped ship, they might get the message.

I work on the 38th floor, and reception always cuts in and out.

I get no reception in my apartment and basically have to step out every now and then find out if I've received a call or to make a call. I would not recommend T-Mobile to anyone.
