trying to unlock AT&T s8+ - Samsung Galaxy S8+ Questions & Answers

I've already gotten the unlock code from AT&T. The unlock instructions say to use a non AT&T Sim card. What Sim card do I use? And where can I buy it? Thanks!!

US phone, you can use any other company. Go hit up a cell store at your pick. Where r u located?

In in the US, Virginia specifically. So since VZ is the other major option in my area I can go to a store and buy just a sim card with no hassle?

Indeed. Don't buy a new one, no need to pay for it. You need the non-AT&T SIM card for only a few minutes so you can perform the unlock process.

So I just use the non AT&T Sim only as long as the unlocking process takes, eh? So that means I put my current Sim back in it? And if that's the case, will I be able to use my phone in areas with little or no AT&T coverage without having to swap out Sims?
Did I mention that this is my first time unlocking a phone? LoL

yea you have to Use another carrier sim to get the popup to come up to enter the unlock code. Then u can put att sim back in..
You will have to swap the sims to use each carrier......
I am in a the wonderful state of vermont now lol

So if you have to swap Sims, I may as well buy the non AT&T Sim and use it for the unlocking process, as well, right?
Vermont, you say? Never been. I'll take your word that it's wonderful.

You could yes as if u want [email protected] network u have to use their sim and say if u want to use T Mobile You insert their sim
So yea if you say want to use theirs as if you dont have signal and plan on purchasing their "plan"

So, technically, if you use the non AT&T Sim you would have to pay to use their network? Wow, should have saw that coming. Lol Nothing is free. Well now I feel kind of stupid. Oh well, live and learn I suppose.

u dont need a different SIM to test if is unlocked.
simply, open the dialer
dial: #7465625*638*#
enter the code u received thats specific to your device, then it should say unlock successful.
hope this helps ya.

yes. now, keep in mind, as this is the AT&T variant, its unlocked for GSM only .so if ur switching carriers, make sure it says GSM. Sim cards that use CDMA wont work like Verizon or Sprint.

Well, I can't switch carriers. Not sure I'd want to anyway. But other than being able to switch to any carrier (and have to pay to do so) is there no other benefits of unlocking a phone?

Not really. It just allows other carriers to work. And it will have a higher resale value as it's not just tied to AT&T.

Oh ok. Thanks for the info. I can say I learned something, if nothing else.

Well, it it's unlocked, able to use any other GSM networks now, functionally it is now a 'universal' phone, as most out of US carriers are GSM. That is one important need for me.

So are all verizon Rhodium phones CDMA with GSM only when out of country?
Which meaning at the moment have no HARD-spl and are able to flash?
I've added some custom apps to my phone which is from verizon and is not flashed. So i was just curious.
Thanks,
Alfredo

If you call Verizon (and have their service for awhile, in good standing) they will guide you to unlocking the SIM slot 'for use outside of the country'. Once unlocked, it will work with TMobile, AT&T and any other GSM provider in the US that doesn't do IMEI checking, or that allow the TP2 on their network, in which IMEI checking wouldn't be a problem.
Anyways, get the unlock code for your device (specific to your device) from Verizon, scroll to SETTINGS on the homescreen, click ALL SETTINGS, click PERSONAL, click SECURITY and enter the unlock code they gave you and your phone will SIM unlock itself.
As for Hard-SPL, I haven't seen anything about it yet.. but I haven't been searching, since the phone already does what I'd like it to with simple cab installs.
I hope this helps!
-mak
Yeah ive had verizon for a good amount of years now. So i might give that a try. and yeah. I agree about hard SPL.
Are there any other advantages to unlocking the sim card other then being able to change services?
I am still new with all this, and unaware the advantages of unlocking the SIM card.
Curious for In Country and Out of country.
Like what are benefits of it while still in the states?
and what are the benefits if i go to canada? does this mean i don't have to pay extra for the plan while in canada to make phonecalls/texts/data?

I believe you may be incorrect on that, check this out, I have yet to verify this my self but from what I have read here and other places the GSM will be unlocked for use overseas. This way you can use another country's SIM card instead of Verizon's SIM (expensive rates) while overseas for an extended period of time.
There are now several threads in several forums about this.
What people often leave out when they talk about what their phone can do is what carrier they have it on.
With Verizon, when you SIM Unlock the phone you can toss in any SIM and it'll work. I personally have a UK SIM and works fine in the US on my Verizon TP2 unlocked. Others have reported using TMobile (US) or AT&T (US) SIM's just fine in their Verizon TP2's after unlocking.
Sprint TP2's come unlocked but will NOT register at all on US carriers (even with a foreign SIM).

Oh so i have to somehow get a hold of another sim card?
nowwww i get it.
so unless i plan on actually going out of country there really is no point in unlocking my phone.

I unlocked mine, just in case I ever decide to leave Verizon to go to Tmobile or AT&T (yeah, right lol).. or for when I upgrade, it makes it more universal when it comes time to sell it.
It costs you nothing if you're a Verizon customer in good standing, I'd unlock it just in case
-mak
Yeah good point. I was more curious on flashing purposes, but TBH i have no use to flash it. Though once the markeplace comes out, im assuming its going to be like the iphones appstore? and hoping in time we find ways to "jailbreak" or something to get them free, thats always fun lol.
Now i do travel to canada a lot. But unlocking it has no use unless i actually pay for the plan and a sim card? I know verizon offers a plan for it, but i dont got that much to where il pay extra for the plan was just curious.

some folks over at PPCGeeks pointed out that in some situations, it might be cheaper to just buy a prepaid sim card when traveling abroad, as the prepaid cards could prove to be a cheaper alternative to verizon's international roaming rates through verizon's sim card, included with the Rhodium.
Alright, thanks i'll look into that.
the problem with going to canada is the sim card has nothing to do with their network. it is still CDMA in canada and while you may have an unlocked phone and different sim card, verizons network will still pick up your phone and charge you accordingly.

If you have an unlocked phone and a different SIM card in, if you set it to GSM mode Verizon won't/can't charge you for using it in Canada.
Hope thatyour right iamrobk, elsewise im confused.

That depends, As CDMA doesnt uses sims for anything other then LTE data here. You should be able to unlock them easy enough but I would not expect it to be 100%

Ok then most Verizon or Sprint phones will work as they are the only CDMA carriers really left in the states right now. Until they upgrade to GSM networks.

Look your issue is that the one with a sim card on cdma use the sim for data only. They don't use it for calls as the dialer only works with one or the other. As for easily unlockable that depends on if the carrier is willing to unlock it. It sounds like you are trying to do this on as a business and if that is the case you will find no help here.

[Q] SIM unlock for Canadian GSM carrier

I used to be with Verizon but switched to Sprint 2 months ago. I have a friend who is visiting from Canada and I figured they'd get more use out of this phone since I don't plan on going back to Verizon anytime soon and this phone is quite old. I tried putting their SIM in the phone and the phone asked for an unlock code. I've been doing some research on here but it seems like no one can guarantee a good solution for unlocking.
If I ask Verizon nicely, will they give me the unlock code?
Or do I need to search for a third party? How reliable are those? And there are apparently SIMs I can purchase that will unlock the phone? Which is better?
Honestly, I'd prefer a free option, but I want to make sure when my friend heads back to Canada next week, the phone will work without any further action required.
Thanks for your help.
The only guaranteed ways are either contacting Verizon Global Support (and you must have an active account in good standing with them for at least 6 months) or using a hardware dongle called SigmaKey which is $120.
Online unlocking services are “unreliable” as in, it depends on whether you're lucky enough to have a device with its unlock code unchanged.

turbo sims may work fine for calls and texts, but burn out very fast using data.

Is this referring to mobile data only? I.e. wifi is okay to use? My buddy doesn't have a data plan so this could be ideal.
Very thorough response. Thank you for your help!
yes, wifi does not use the sim card

[Q] Motorola Droid Ultra XT1080M on ATT

Just a quick question I hope I can get a quick reply on.to help a friend. From what I can tell this phone should work on ATT with a carrier unlock. Just want to be 100% sure before I tell him to go ahead and buy one. But from what I can tell it should be fine (Although may or may not have 4G on ATT, but thats not hugely important).

Thats what I thought. Just wanted to be sure. Ive never had to deal with bringing a phone from one carrier to another before. I know it needs to be carrier unlocked. Just wasn't 100% sure if GSM was ATT compatible. Also thanks for the advice on the ebay protect. Will let my friend know about that.

Method to move phone from Fi to Verizon?

My wife and I got the Google Fi BOGO deal. My wife is staying on Fi, but work pays for a Verizon line for myself. So we bought both phones, and are going to pay for 1 month of Fi for my line, and keep hers going on Fi. Phones just arrived. Wondering what order I should do things to bootloader unlock & root. Hearing some of the horror stories with switching carriers, so I wanted to see if someone has the correct order I should use to do my unlocks, swapping out SIM, etc. I already got charged for the phone, so it shouldn't be carrier locked.
Do you already have an active Verizon SIM? If so, you just put it into your phone and you're good to go.

I didn't buy from Fi but Google Store. I had an active VZW SIM in my Pixel 2 XL and popped it into my 3 XL, simple as that. Unlocking the bootloader and rooting is still possible after using a VZW SIM. Only the IMEIs sold by VZE/BBY should be locked/disabled.
Unlocking the bootloader wipes the device, so it's usually best to do that first at a minimum before setting anything up so you don't have to set everything up twice.
