Please let me know how that works out for you, I am in the exact situation that you are in. I currently have Sprint and the data speeds are terrible. I have been doing a lot of reading about Straight Talk and the AT&T Sim. I am curious if the coverage matches that of the contract based AT&T service. I am all for paying a bit more money upfront for the $45 per month that they offer along with the AT&T data speeds.
Keep me posted if you would. BTW, I live in NC. I am sure area makes a difference.

I'll give you my opinion....I've had ST for about 6 months now and was previously with Sprint for about 5 years.
I would say that Sprint had exceptional voice quality and signal while the data was pathetically slow and when I traveled(Even on major highways)it was nearly non-existent. Now with ST, building penetration is a bit of an issue. I had the same problem when I briefly went to T-Mobile but ST is much better then T-Mo was.
The data is much faster with ST but it also seems sort of a wash since it is limited indoors. Also, you have to watch your data and make sure you don't go over what is considered the invisible limit. Which is roughly 200mb a day or 2gb a month.
Since I am a cheap person I do love my plan though. $45 a month is a great deal in comparison. I pay for 2 phones so my total is about $97 after taxes, instead of $110 on my EPRP from Sprint plus the taxes and fees with Sprint that add up to more like $130 ish.
I am from a non popular town so none of the carriers here work perfectly. I will say for the price I am paying its certainly worth the trade off of being locked down to a contract.
Hope it helps and GL with your decision.
Edit - I would also like to point out that when I was with Sprint(and now) I was always wanting to change up phones and try something different. I went with an iPhone recently to see what the fuss was about. Since it was just a sim I just cut my old one and put it in new phone and I am good to go. Unfortunately now that I cut it I can't get it back so I had to order a new one. But my point is if you like to switch phones a lot and try new things out then this service is perfect imo.
