Back in Feb, Straight Talk started a new service called "Bring Your Own Phone" (BYOP), where ANY sim phone will get a sim to be on the Straight Talk AT&T & T-Mobile networks.
It's NOT the "regular" Straight Talk from Wal-mart with bargain bin phones. This new "division" even has its own URL: StraightTalkSIM.COM
If you bring an HSPA+ phone, you will get HSPA+ speeds on AT&T and/or T-Mobile. "Regular" Straight Talk uses all four major carriers and they sell phones at Wal-Mart tied to one of those carriers (Verizon, Sprint, AT&T, etc.) This is NOT regular Straight Talk.
This BYOP sim plan is only for AT&T and T-Mobile network. When you sign up you choose which sim you want. ST "AT&T" or ST "T-mobile". If you are bringing an AT&T phone, best to sign up for the "AT&T" sim and vice versa. Because AT&T and T-Mobile use different frequencies for their HSPA+ signal. (Just like Verizon and Metro use different frequencies for their LTE.)
HOWEVER, if you sign up for AT&T sim and you come into an area that has no AT&T but has T-Mobile, you will "roam" for free on T-Mobile towers. But it's not really roaming, you just switch over to T-Mobile towers per ST's agreement with T-Mobile. If you are using a phone that gets AT&T HSPA+ and does not have the T-Mobile HSPA chipset, normally you would drop down to EDGE speeds.
But if you have a phone that has ALL the necessary chipsets (a pentaband phone), then when you "roam" on the other towers you will still get HSPA+ speeds. The GSM Galaxy Nexus IS such a phone. It's an "international" phone and can receive both AT&T and T-mobile HSPA+ signals.
I signed up, ordered the sim ($15 one-time fee). I ordered Galaxy Nexus from Google ($349 + tax and shipping). I put sim in phone. I activate account. I am happy. $45 + couple dollars in taxes per month. About $47 per month. Cheaper than Metro, I have very good speeds, I have a dual core, 4.65", 4.1 Jelly Bean phone.
Did the same for my wife. We both have Galaxy Nexus on Straight Talk, using the ST "AT&T" sim -- and can use T-Mobile towers with HSPA+ speed when necessary.
Unlimited talk and text -- and true nationwide coverage.

Cons: not a con for me but for some. They claim unlimited data, too but after 2GB in many areas, but not all, they impose a 2GB data cap per month over the mobile network. After 2GB, they throttle you. Not 2GB total, just over the mobile network. They also don't like it if you use over 100MB per day. Others say they go to 5GB regularly, no big deal. Still, enough warn of the 2GB cap and being throttled that's it seems real. Some say it depends on the area you are in.
Anyway, doesn't matter to me. So far n 3 weeks I've used 1.4GB over wi-fi and only 500MB over mobile. All together I will use over 2GB this month, but all that counts is the "mobile" part.

So, bring any phone you want -- just has to be a sim card phone. Great speeds if you have an HSPA+ capable phone, and only $45 per month.
If you pay for multiple months, they discount. 3 months, 6 months, even a year in advance gets you in to the low $40s. Also when you pay each month if you give a non-tax state zip code like Oregon, taxes are waived.
When I found out about this deal, especially being able to get the phone I wanted RIGHT NOW, I was intrigued. After a couple days researching and trying to figure out the "catch", I decided to go ahead and do it already!

Now I just need to figure out if the unlocked S3 can get HSPA+ on both T-Mobile and AT&T...


Left Metro earlier this month, after a dozen years. Got two Galaxy Nexus with 4.1.1 Jelly Bean.
