I have used both and I'm currently using Nextel. Sprint has a wider coverage area but does cost more. If you want a phone with picture capabilities Sprint probably has a better plan. If you are going to be in major metropolitian areas, you might want to look at NEXTEL. I was paying $37.00 a month with sprint for one phone and getting 300 anytime minutes (Sprint does have larger plans, but this plan met my needs). With NEXTEL I get 400 anytime minutes 500 direct connect minutes for 2 phones and the cost is under $55.00 (I do get a substantial discount because of my employer better than Sprint). All other things being equal (web service, 3 way calling, etc...) both have execellent plans and service. For me Nextel is a better plan I do travel a little and the coverage is in the areas that I travel to and the Push-to-talk option allows me to talk to some people instantly.
I would reccommend that you you consider where you travel to then think about how much air time you need. I know both companies have discounts for IBM employees but NEXTEL has discounts for Military as well. You will need to ask about the company that you work for. Everything else is equal.
see...right now i have AT&T and it sucks...but i heard good things from both Sprint and Nextel. I travel alot cross the US so.........anyone who travels within the US and have either Nextel and Sprint, please tell me which has the better coverage.
Also, anyone who just has either carrier..please tell whether your coverage is good or bad and if u have any drop calls
i live in chicago, which shouldnt be a problem b/c coverage over here is good but then again, i travel alot so thats y i am asking everyone
