As long as you are using Straight Talk "AT&T" nothing needs to be unlocked. You are still on AT&T, but just using a high-lag MNVO.

WHICH carrier is your Straight Talk SIM card using? Straight Talk resells service from all four major carriers.

If you're using Straight Talk "T-Mobile", then you've got a problem.

I have already pre-ordered Samsung Galaxy S8 and S8+ for me and my wife, will get it on 29th April. The both phones are from AT&T and I want to ask. Can I unlock them same day for Straight Talk carrier usage? I have a plan with straight talk with a cheap calls so I want to switch to them at the same day. found this this service where S8 already supported for sim unlocking. have somebody used this service before ? just want to be sure before making order there

You probably dont need a pay service or any service at all to sim unlock it. AT&T has a website to unlock phones if they meet the criteria you just enter the info and they unlock it if you qualify.

Should have bought a Verizon model in that case since they come sim unlocked.

They unlock it only if you do not owe any money of the phone

just a quick experience share. I've tried the service from the first post (Mod Edit). my s8+ was locked with a highest level of encryption (hard locked) by carrier, so delivery time was around 12 hours. price was 26 $ ( 13 $ first charge + 13 $ pending amount for hard locked phone). unlock code worked well from the first try and phone is unlocked now (switched from t-mobile to vodafone because they have better mobile data speed). thanks for the link. cheers

Did you just say t-mobile? They use their own device unlock app right? I wonder how you were able to unlock t-mobile Samsung Galaxy S8.

He's using T-Mobile Europe, not T-Mobile USA. Did you not see the Vodafone reference?

Looks like I skipped that part

Deutsche Telekom is the parent company of T-Mobile and that brand is used in some European countries, besides the U.S. At one point, 13 countries had "T-Mobile".

This really sucks for me. I contacted them before ordering sim Unlock for T-Mobile USA. They said since all the services are down for T-Mobile through the official app they are doing it differently where I will have to use an app made by them to enter the unlock code. Everything was fine until today when I got email from them with unlock code and Network Unlock app. I followed there instruction but their app does nothing. its useless, its like a dummy app.
App says "Connecting to server..." while it doesn't even have internet access permission. I checked by disabling the wifi and mobile data, it was still functional (as expected because it had no internet excess) it prompted me to enter unlock code but it does nothing except for saying Permanently Unlocked it literally does nothing else after entering the code. Later on I tried entering wrong codes as well and it would still say Permanently Unlocked. I have sent them multiple emails and messages but no reply yet.

I am guess the unlock code they provided might be correct but there is no way to enter it on phone since it is T-Mobile variant and only Device Unlock App can enter the unlock code.

I bought a ATT version on day one of release and paid full retail at Best buy. Figured I can unlock via their site. Nope, in fact the IMEI # wasn't coming up at all. Kept saying it was not in the system. I called ATT but they couldn't help so I returned it and bought the Verizon version and works fine on Tmo via MintSim. Only bad thing is I have to use desktop software to update since it's not on the Verizon network.

Mod Editis having a 2 day sale 30% off for $13 (vs $19). How can you tell if your phone is "hard locked"?

I'm assuming the VZW version is sim unlocked out of the box?

Correct, all their LTE phones are unlocked but they may not have the bands required for whichever provider one is looking to use it on. The S8 has the most bands that I read of the US releases though

Only cost £10 on eBay for a unlock code

I tried androidsimunlock.net who are my usual go to guys and they couldn't do it. So I paid at samsungsimunlock but haven't heard anything back yet. It's been over 12 hours, I've even emailed to follow up but heard nothing.

Anyone else used these guys successfully?

yes, my phone is from t-mobile. do you mean pre-installed t-mobile device unlock app? I have tried to unlock my phone using that app too but with no success. every time I hit the unlock button the phone just displayed an error.
samsungsimunlock com provided Network Unlock app and after I've completed all steps from the step by step guide it said "your device is permanently unlocked". I've rebooted the phone with my vodafone sim card and the phone accepted it. also I have tried orange and three carrier sim cards, they all are worked well also. 4g/LTE is working well too :victory:

I followed their steps too but no luck yet. I have no idea why it does not work for me. After I was frustrated I decided crack down their app a little bit. It doesn't have any phone permission, I am guessing it cant put Unlock Code for the phone and the other thing is I tried some random numbers and it still said Permanently Unlocked.
Do you need to have the app installed all the time or is it fine to remove afterwards?
