Not sure what all the complaints about T-Mobile are about but in my experience my old 2 year old Nokia (am about to upgrade for Christmas) gets great reception throughout Valencia and down the 5 to my work. I had AT&T and Cingular for over 8 years and was constantly calling them for billing errors, but with T-Mobile they've been nothing but kind and courteous the few times that I have called and haven't made a single mistake on my bill in the 3 years I've been a customer.

I have read a great deal of complaints about Cingular. I have recently switched from Nextel to Cingular and am very happy. I called Cingular customer service once about a bill and the Rep was more than pleasant. One other call about dust collecting underneath the screen and the next day I had a brand new phone on my door step! As for the reception, (Santa Clarita and SF Valley) Cingular is 100% better than Nextel. So far I am extremely happy with Cingular...

T-Mobile only one with 5 bars at this location (home) and at office in LA! Cingular was <1. Verizon was around 3 bars but <1 at work. Sprint was around 3 bars but <1 at work. T-Mobile is the service for me and am very happy..finally.

Verizon is pretty excellent all throughout Southern California. I get a minimum of "Average" to "Perfect" for reception in the Santa Clarita Valley for Verizon ^^

Full signal but sometimes interference in parts of the house. Outside almost perfect 24 / 7. Recently changed to iPhone 3GS / ATT for the hardware. No issues with VZW.

Just got the 3GS. Five bars of signal and 1.2 / 700 Mbps 3G internet speed. One dropped call, a couple no ring voice mails. All in all not too bad.

I have had no problems with cell phone reception on the ground and inside my apartment (3rd floor).

Great Reception. Company is horrible to deal with though. They constantly make billing errors and you spend hours on the phone trying to resolve them with no appology.

Most areas in Santa Clarita have good to excellent coverage on AT&T GSM and my phone will roam over to Cingular in the few poor areas that there are (inside my house). The only poor area for both AT&TWS and Cingular GSM is on Seco Canyon road from Bouquet Canyon to Copper Hill drive. Cingular and AT&TWS have signal ratings worse than -105 dBm on GSM 850 and 1900.

Call-in - very poor: A caller trying to contact me connects directly on 1st attempt 50% of the time vs. caller leaving voice mail message. Call-out - very poor: I receive "no network coverage" message more frequently than making connection when attempting a call. 2nd attempt to contact required.

Very inconsistent... 1 to 4 bars in a matter of seconds.

My calls always drop and fail beginning with 2-3 bars at start of conversation. Receiving end always says I am breaking up. Microcell 3G unit seems to be the best option from ATT. Most frustrating thing - Should not have to purchase for their problem - cell phones are expensive enough!

I'm replacing my LG phone I've had for 1 1 / 2 years. It's been a dud since I got it (lousy reception most anywhere), so this isn' a real test of Verizon's call quality. I have the same problems all over So. CA (especially inside office bldgs.). Very frustrating phone, but Verizon is good to work with.

Got 2 bars at most inside the house, though coverage outside (even on the front porch) seemed to be better. Great coverage around Valencia in general. Just not inside the house for some reason.

Will Routinely Drop calls... better downtown

worst phone don't buy one I have had to have five replacements sent all of them stop working after about 2 months screen stops working worse phone don't buy

At&t drops my calls daily and most of the time my phone does not ring when I receive a call. The reception stinks because if you move around when you talk your call is dropped. Not what we pay for.

I have Verizon Wireless and have changed 3 phones to get good reception and it doesn't matter which phone I get. My reception used to be great but in the last 5 months reception has deteriorated with me getting dropped calls for almost every phone call. I'm done. I'm switching to another carrier, probably Sprint.

Can only get reception in one part of our house. Even in that location, breaks up from time to time.

I have had great service for years but in the last 6 months it has gotten worse every day in every area don't even think about making a call on the 5 anymore
