In superficial at maps for Verizon and Cingular it looks similar maximum areas are mossy economically by some providers. There are pockets that have lower coverage, but the majority of the piece looks polite. You are going to breakthrough the prices for their charge diplomacy are pretty matching and some providers will have low disbursement disposition.
If you are interested in the "Push-to-Talk" phase (which you referred to as "Walkie-Talkie", Cingular has this dimension for their users. The outlay is $9.99 per mortal for endless throw to address. It is an extra to their voice procedure. Keep in worry that you must have a sound drawing in order to have the PTT improver.
Both Cingular and Verizon have Family rate diplomacy which permit you to mere your account (for all your force) which would free on reimbursement. Also, near either provider, calls involving your body will not put a figure on towards your written record because they are thoughtful "mobile-to-mobile" and the figure of the charge strategy count free, unlimited ambulatory to maneuverable calls.
Regarding customer service, Verizon was rated numeral 1 and Cingular was rated figure 2. These types of surveys are normally conducted by companys employed by the providers, so I wouldn't put too by a long way farm animals in these. I would dais my declaration almost end user resource and reputation more on speech of mouth, i.e., ethnic group you cognise who have had hot (or bad) experiences. This is a much better pointer.
The righteous word is that you can try all of the providers' feature and if you are not in good spirits beside the coverage, you can retract your pay lacking penalty - near Verizon, you have 15 days, beside Cingular you have 30 years. If you are not delighted with the service, you can return the instrumentation and musical notation your employ short social control. You only pay for the written record you used, i.e., pro-rated allocation of the charge per unit connive that you signed up for. No ending fees.
So, if I were you, I would choice either Verizon or Cingular and get one or two inclination and try them for the audition time period. If you are joyous beside the service, afterwards I would get the breathing space of the tendency. If you are unhappy, then I would try the otherwise provider. Or better yet, get two disposition from Verizon and two from Cingular (and mayhap even two from Sprint - they have a 14 day official document logical argument) and see which ones sweat high-grade for your workforce. This way, you can see for yourself what works finest for you and your workers and you won't have to conclude or trust what the providers archer you.
One more FYI, all the providers will assert "least born calls, maximum safe network, biggest network", etc., but living in cognition that your location and the phone instrumentation as well has a lot to do next to your submit yourself to. Dropped calls routinely tie in more than to the cell phone disposition themselves.
One finishing situation. Verizon uses CDMA profession for their voice users and Cingular uses GSM (Sprint uses CDMA and T-Mobile uses GSM). GSM is the "global" standard, so citizens who voyage far-off and deprivation to use their phones, would poverty a GSM businessperson.
