The Straight Talk Samsung Galaxy Precedent coverage area map shows that it uses the Sprint network as the carrier, but the question came up in regards to roaming.
This map gives a general idea of the service, but you can click here to go to the Straight Talk website where you can enter your zipcode and see if the Precedent is available in your area.
Also, to get a closer look it's helpful to look at the Virgin Mobile coverage maps, since they also use Sprint.
But will the Straight Talk Samusung Galaxy roam when it leave the Sprint coverage area? I did a little test today to find out.
According to the Virgin Mobile map, the Sprint network should not cover the little town of Everton, MO, which is a half an hour or so away from my home.
My 4 year old daughter wakes up at 6am every day, without fail, no matter how late I got to bed the night before. Sigh. Anyway, today we got up at 6, packed some snacks, and hit the road for Everton. What I found was that on HWY 160 between Ash Grove and Everton, I could still get coverage when I was up on the hills, but in the low spots and in the town of Everton itself I got this:
Alas, no roaming. So far, I've been happy with the Galaxy. Everything I've tested so far seems to work as expected with nothing locked down, but the limited Sprint coverage area may be a show stopper for some of you.
For others, however, it might not be that big of a deal. Many people don't regularly venture outside of population areas and highways, and sometimes it's a blessing that your cell phone just won't work when you're on vacation or at the lake. $45/month for a no contract Android phone with unlimited talk and text and (mostly) unlimited data is a pretty sweet deal, and if it has coverage in 99% of the places that you normally go, then it may be worth it.
It's also important to mention that other stuff on the phone works, even when you're outside the coverage area. For instance, you can still take pictures and videos, you can still play all of your music, and you can still run apps that don't require an internet connection. The GPS works too, though Google Maps won't be able to download the higher resolution maps as you travel through an area with no coverage.
Anyway, you'll have to make the call on how much the coverage area will impact your usage of the phone.
One last thing. I may be aging myself here, but in my day we didn't worry about coverage maps because we didn't have fancy cell phones at all. We talked using tin cans and string, and we LIKED it! Now, get off of my lawn. :)
