That's too bad about AT&T; I see what you're talking about. If you look at the map on AT&T's "coverage viewer", there's an almost 100% chance you're currently using someone else's towers in the northern half of the state, but you're not getting charged for roaming because of the national family plan you have. I suppose their setup with the prepaid coverage makes some kind of sense for them.

The zip code entry coverage maps for Net 10 denote roaming as literally anything outside the home area. I see they only charge 10 cents a minute for local/roaming/long distance, which I guess is a good deal for prepaid if that's actually the case (so to speak) and the service provided in roaming areas is reliable. Home area coverage from Tracfone is indeed apparently identical to Net 10, see their Jackson Pollock style national coverage maps in comparison:

EDIT: Now the Tracfone isn't working, maybe it will later. Go
here, type in a zip code where you know there's no chance of getting coverage, and it will give you a national coverage map.
as well as their zip code entry coverage maps in comparison, which look the same for any given zip code (from what I saw). Note: if they don't look the same, I swear on my mother's grave that they look identical most of the time; it's changed on me three times already. Sometimes the green areas on the Net 10 map look all bloated, and sometimes it looks exactly like the Tracfone map. I'm not making this up. Not saying they're trying to be tricky, maybe the spidery one is their GSM 1900 home area and the fat one is their GSM 850 roaming somehow. That would be interesting if that were the case.

FWIW "Net10" and "TracFone" have the same parent company, and I think have the same coverage map. The difference is in the pricing plans.
I agree. Net 10 has
a little snippet about this on their website. Telcel is apparently a subsidiary of América Móvil, which has a roaming agreement with Smith Bagley, Inc. (CellularOne) for GSM 850/1900 coverage according to
this website, so: "super-theoretically" Net 10 and Tracfone have a roaming agreement with Cellular One under those bands, assuming the site is updated regularly and I'm not reading into it incorrectly.
This is from a section in the Tracfone website after you pull up a coverage map using the zip code entry method (I added the bold highlights):
Quote:
The coverage map above is for your general information only; it should not be relied upon by you and does not form a part of any agreement between you and TracFone Wireless, Inc. The coverage map shows an approximation of outdoor coverage and is not a guarantee of coverage in any area whatsoever. In general, your TracFone handset should be able to make and receive calls in both the green and white shaded areas of the maps shown. However, actual coverage area may differ substantially from map graphics, and coverage may be affected by such things as terrain, weather, foliage, buildings and other construction, signal strength, customer equipment and other factors. Your ability to place or receive calls (including 911 calls) may be temporarily interrupted. In addition, there are some areas where there may be no wireless coverage available. The roaming rate of two units per minute will generally apply in the white shaded area, but may apply even in the green shaded area under certain conditions. Charges will be based on the location of the site receiving and transmitting the call, not the location of the person making the call. Please read the sections entitled "Coverage Maps" and "Roaming" by clicking on the link for "Terms and Conditions of Service" below for a complete description of roaming and roaming charges.
I'm willing to believe you're safe in the green areas with Net 10 or Tracfone, and by appearances at least, you can get roaming almost anywhere else within reasonable constraints, which "generally" costs you double with Tracfone and 10 cents a minute with Net 10.
If you do happen to do all your calling on the northern corners, you might want to also look at prepaid from Alltel:
http://www.alltelu.com/plans/pay-per-minute.php
From the
coverage map on Alltel's site, it seems like you're alright if you do most of your calling there, but the north central part of the state still gets the shaft and they stick it to you at 59 cents per minute for roaming, which seems more believable to me. Alltel has $100 refill cards with 1 year expiration periods and $55 – $99.99 refills with 180 day expiration periods, but their price per minute is a little higher at 15 cents.
Have fun sorting through this, hope you can find something that works for you.
