[Q] Straight talk - AT&T Samsung Galaxy S II Skyrocket SGH-I727

ok so i learned today that you can roam on the tmobile side of straight talk. With a ATT sim card and get data. how do we do this i read the thread about the aws band and tmobile radio and i read the recent unlock thread free method. if i put the tmobile modem on and unlock will i be able to achieve this?
the tmobile side gets way faster 3g than att ive noticed.
I have a spring galaxy s3 and it uses roam control an app to force roaming. how do i do this running aokp.on the skyrocket

[Q] Force Roaming on ATT (from Tmo)?

Hi All,
Is it possible to force data roaming to pick up an ATT 3g signal? I have Tmo but only edge where I live, and for $30/month data edge just isn't going to cut it!
I have messed around with "service mode" to select a specific band frequency, but I either get edge or no service at all.
On a side note, my sgs4g is unlocked and I was able to get 3g when using a straighttalk sim (again ATT signal). Is it possible to get connected when using a Tmo sim?
This could save me a HEFTY E.T.F. .... :/
Not sure or it's possible, but my suggestion is that you flash modems from this thread http://forum.xda-developers.com/showthread.php?t=1192436, lemme know if anything.

[Q] How to get 4g on my Sidekick 4g with at&?

So I bought a sidekick 4g thinking I could use my at&t sim card for it and got it unlocked but have one problem. I can only get 2g at the most on my network and asked the service provider who provided me with the unlock code for a solution to this. They told me something about T-Mobile running a different network than at&t and how at&t was updating there network so that I could get 4g on my phone and how it was going to be ready before the end of this year... Is it possible to get 4g yet or any other way around this?

Nope, that person lied to you as well.
AT&T and T-Mobile have different HSPA (4G technically) bands. I think AT&T uses the 850mhz HSPA Band, while T-Mobile uses a different one. Since thats the case, your SIM Card is looking for a band that the phones modem dosent have. Thus, knocks you back to EDGE. Forever.

That gsm setting is only edge on vzw phone, no highspeed data. It may be possible to get high-speed data though, what carrier is the sim from straight talk on?

OK...that might be a problem. As I said with gsm its only edge. The LTE on at&t vs vzw uses a different frequency AFAIK. There is a possibility of getting 3g connectivity. There is a thread where someone got 3g on T-Mobile with a vzw gs3, I'll drop a link, might be a good starting point.

[Q] VZW SAMSUNG GS3 4G LTE ON Straight Talk?

Is LTE CDMA and GSM?

Hi folks,
I live in a black hole of cellular signal. The only provider that has towers where I live is Verizon. I drive 45 minutes to work every day and over there both Verizon and AT&T have towers. I'm currently using a small, local carrier that uses Verizon towers and phones. I bought a Nexus 6 and want to activate it on straight talk. I thought I could use the IMEI from my existing phone, since it's a Verizon phone, but they say it's not compatible. They say they can activate it as a GSM phone, but I've read that if I activate it as a GSM device, it will not connect to Verizon towers so would basically be useless where I live. However, that doesn't really make sense to me since the Nexus 6 has both CDMA and GSM radios in it.
Does anyone know if I activate a GSM sim and pop it in my Nexus 6 if it will connect to Verizon towers? We do have LTE here, if that makes a difference Thanks for any help you can provide!.
Verizon network will only use CDMA but you could still use it in roaming
