The only issue I have with AT&T is that I do not get any service in my work building and the phone I want to get has a locked boot loader so I can't root it. I was thinking about going to T-Mobile but their monthly bill would have been a lot more than what I'm paying now, they wanted around $180 for 2 phones a month with a $260 up front payment.
I would like to borrow/rent a sprint phone for a week and check out their service before I commit. I don't want to switch services and lose my unlimited data if their service sucks.
My husband would get barely any service at work and had trouble in the surrounding area with AT&T. This was not too far from Madison Square Park.

I don't think Sprint is much better. My uncle had Sprint before he switched to Verizon and whenever he went to my parents' house in Brooklyn, he had zero service as soon as he stepped in the door.
Sprint and Verizon use CDMA technology and are the only carriers in the world that do. CDMA has problems penitrating brick and concrete walls. Every other carrier in the world uses GSM so that's why there's issues getting a signal indoors with sprint and Verizon.

This is simply 100% wrong.
The network protocol (GSM or CDMA) has absolutely nothing to do with how effective the signal is at penetrating a building (or anything else, for that matter).
That is determined by the frequency at which the signal is broadcast. The lower the frequency, the greater the range and the better the signal can penetrate objects.
T-Mobile and Sprint both have primarily used high frequencies (1900Mhz) up until quite recently. AT&T and Verizon have used lower frequencies (800/850Mhz) but do add in some 1900mhz stuff in densely populated areas.
I pressed *2 on the phone and the Sprint customer service rep said: Our CDMA phones have trouble penitrating bricks, high rises, and cement.
I guess you better press *2 and get that person fired cause he's bringing Sprint down with him.
@Deeken - you must have really bad credit because 2 lines is only $80.00 and depending on what phone you get the installments plans for 2 lines could be an extra $50.00 on top of $80 which is $130.00. Of course, you can always get a low end model phone and save the most money.

This is extremely basic physics. The fact that some guy working in a Sprint call center says otherwise does not change that fact. A big red flag that he's wrong is the obvious fact that the phone doesn't penetrate anything, the signal from the tower does. An 800Mhz signal transmitted from the same location and at the same power as a 1900Mhz signal will always have greater building penetration and range. It makes absolutely no difference whatsoever what the network protocol involved was (CDMA or GSM).
Physics 101: The lower the frequency, the longer the propagation wave.
Look at it on the extreme end. Communications to nuclear submarines operating in the depths of the oceans take place as low as 3hz. The wavelength of something like that will be tens of thousands of miles long. It will have insane range and be able to penetrate entire mountain ranges or thousands of feet of seawater.
It's same principle comparing any two signals, where keeping all else the same, one has a lower frequency than the other.

Sprint and Verizon should hire you as chief engineer. Your techno wisdom is second to none.

Except that my husband had AT&T (trouble with signal indoors) and my uncle had Sprint (trouble with signal indoors) and the only service that has had zero issue with Verizon. Both ended up switching to Verizon.
