use a gophone?

I am visiting US for a month.
I bought an AT&T gophone cheap phone with unlimited text, data and calls.
The sales rep at bestbuy told me that I can use that SIM with any other unlocked mobile phone.
Now the sim is only working in the gophone. Any other unlocked phone is not recognizing the sim.
Is there any workaround for this? In S4 or any other android phone is possible to use that SIM?
I tried returning but the set can be returned not the packgage(calling minutes etc).
Thanks in advance.

Your should be able to use that sim with any unlocked phone or any att phone. Go to an att store and have them check your sim card. Also, did you apply any locks to your sim card?
Tapped from the Shear Galaxy Near You!

There was a change to the way these Sims work. ATT has them locked to the phone they are shipped with. You will have to have them unlock it before it will work. The person at Best buy probably wasn't aware they changed this about a year ago.

If I take it to an AT&T store, Will they unlock it?

If I remember the policy right it has to be activated for a certain amount of time before they will. You could give it a shot.

"Invalid SIM" - first hand experience while outside the US

So I learned it finally the hard way.
I was told the phone is unlocked.
Tried to to verify it by inserting a foreign SIM card while in the US.
Got invalid SIM message.
Called sprint about 50 times, literally. Got the same answer, it is showing as unlocked in our system, it will work just fine when you are outside the US.
Wen to Germany, and no surprise, it doesn't work, says invalid SIM.
Sprint is absolutely helpless and hopeless, I called them while in Germany and they said the same thing, it shows as unlocked.
The phone never got any OTA for unlocking and Sprint claims there is none for this purposes.
If anyone knows any magic words I should use with them I'd appreciate the help.
I'm stuck here without phone practically.

Have you tried to go into settings /system update then hit "UICC unlock"?

Yeah I wondered what that did.

only a 100 times maybe

told you so
despite what Sprint says... they are not always correct. When properly unlocked, even with a domestic sim, the sim error will go away.

So even though I will never leave the country, what should one do? Never buy a phone that claims international? Buy a cheap throw away if you travel?

Never treat what Sprint says as actual fact.
If you are a GSM-only user, never buy a Sprint device.. even if it claims to be unlocked. Even if unlocked it will never support as many GSM/WCDMA(HSPA) bands as a true GSM version. This may change in the future.. but applies to all current Sprint devices besides maybe an iPhone(ew).
Use wifi as much as possible when traveling to avoid unneeded charges. If you do decide to use international GSM service... buy a local pre-paid SIM card and NEVER use your own carriers international roaming plans unless you like being ripped off.
Don't give up on unlocking the GS4. A method will be out eventually.

So you want to unlock your S IV...

You can't.
You can call Sprint and they can unlock it for you or you can purchase an already unlocked phone.
YES Sprint phones ARE international CAPABLE but have a CDMA CARD. Get it unlocked through SPRINT.
The carrier must unlock your SIM to have GSM capabilities. Period.
There's no magical code, no night gnome who can give you international capabilities, there is no work around. Your card defines your capabilities.
Glad we got that cleared up. Lets stop asking now, shall we? Please?

This is wrong. You can. Just won't work on AT&T and T-Mobile USA. Every other SIM(international) is unlocked for use as long as the SIM slot itself is unlocked.

Interesting. I'll let my co workers at Sprint know

If that was the case more people would be saying "Go into settings and unlock UICC and bam all set international."
The very first releases from Samsung to Sprint - like mine - were actually international, however most of the employees scooped the oops devices. Those purchased at Best Buy still have intermittent unlocked devices 1:20). In the chance you got lucky then NO we don't need to unlock it but yes, for 90% of the S IV population yes, unfortunately there's a very good chance we do. If this was the case the threads would have ceased to continue resurfacing.
So either tell the people so they stop asking or continue ignoring them.

after 90 days Sprint unlocks them when you ask the international department. My phone came sim locked. Had the invalid sim error and everything. It was then unlocked. I have had multiple GS4's unlocked. No more sim error. International sims confirmed working.
the issue is that not everyone asking has waited 90 days. There's a good number of people that have this phone and are't even using Sprint as their carrier. This is where most of the questions and confusion comes from.. those two groups. Then there are the last two groups... those who have been but (incorrectly flagged as unlocked but no true unlock was performed OTA... and those who are just like me that have unlocked and used the device overseas.
Since there's not a ton of Sprint users that have used their device overseas... after waiting 90 days... and being unlocked properly OTA... we arent seeing lots of posts about success... but they exist. Also, you aren't accounting for when the device's unlock method goes public and Sprint is no longer needed. That's the real goal behind all of the unlock questions. How can the phone be hacked to bypass the sim lock. Then everyone can unlock at their own free will. Then the next project will come... getting the unlocked GS4s working on ATT/TMO(something I've already started working on). If you've been paying attention to the HTC forums.. they have just figured out unlock method without needing Sprints help. This was after 80+ pages of people saying it wasnt possible and failed attempts.
You mention Best Buy devices... is there something in the system not allowing anyone that purchased a phone there to not be unlocked? You mention a first batch of phones maybe working... but my most recent GS4 is 2 weeks old.. so surely thats not from the first batch... yet still unlockable.

@autoprime
so if I want to check if my phone came unlocked as you say one of your many gs4's did. All I would have to do would be to buy an international sim from eBay, or amazon if available and pop it in. Then if I don't get the sim error notification, I am unlocked?

none of my phones came unlocked out of the box. they were all unlocked after. then tested with GSM sims... unlock confirmed working. That was my point in responding in this thread... so people knew an unlock was possible.. despite what the OP suggests.
you can use any non-sprint sim card to test if you are unlocked... even AT&T or Tmobile. If you are unlocked.. you wont get a sim card error after booting up with the new sim in. if you get the error, youre not unlocked.

sprint variant?

Can I just change the Sim and use the phone on t mobile or Verizon?

I have the Sprint variant, but right before I turn it on for first time I remove the sim and pup in my Tmobile one and is working perfect

That no longer works with they do now is when you're in the store they turn it on to verify it on their network even if you factory reset with the Sim no longer of a option

so update if you change sims prior to activation in sprint it remains unlocked. However unsure what happens when you put the sprint sim in

If the sprint sim is in, I am pretty sure it locks the phone to their network until you call and request to have it unlocked. I will know soon enough, even though I got the pre-order discount, I hate having phone payments and pay them off as soon as possible.

Some one knows if sprint stores sells screen protectors?

Keep me(us) posted but for testing purposes sake when you open up a sealed box try it with a different carrier first T-Mobile AT&T Orange River you happen to be located verify that it works and then try to put in the Sim card in and see if maybe that doesn't autolock it I'm kind of reaching in granted I don't have a lot of knowledge about these things but again thank you

I know people have been successful, when buying it from Sprint directly. You just have this make sure the phone isn't powered up with a print sim in it. Also Amazon had them back in stock as of a couple days ago.

The next question would be, if someone out right bought an unlocked version and they popped a sprint sim into it what would happen....

Traded in my LG G6 from Sprint on September 13 for the PH-1(Directly from Sprint)..Phone was setup when I walked out of the sprint store..A hour later after a couple of calls and texting I switched over to T-Mobile with no problems..The phone comes unlocked out the gate..Reports told you that before the first phone ever shipped..Factory unlocked with all U.S. LTE bands..

Have you tried putting the sprint sim back in
Here was the first phone that they set up in store

Isn't that saying a locked bootloader, not carrier locked SIM?

I have a essential ph-1 from Sprint and cannot unlock bootloader... Any help?

Moviestar career from Mexico? You failed to mention what model phone you have exactly since everyone knows the US models can't be unlocked.

The model is SM-G9750U, yes Movistar from Mexico. I found this guide: https://forum.xda-developers.com/ve...ow-to-carrier-unlock-stock-sm-g955u1-t3778162 and also this another one: https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657.
Do you think this could work?
Thank you!

He's asking for a SIM unlock, not bootloader unlock, and the Verizon device (as he mentioned, just added a 0 to the model #) gets unlocked naturally after you insert an active SIM into it. Do you know anyone in the US with a Verizon account? It should take a few minutes.

Yes, probably... Do you have any guide to do it? I understand that login to the portal of Verizon and put the IMEI to get the unblock code, correct?
Thank you, I really appreciate your help!

No. You put an active SIM into the device and it unlocks. There's no code request.

Excellent! Thank you, I will give it a try when I have the device. When does it request an unlock code?

It doesn't. You put an active Verizon SIM in, and it unlocks. Then you can use any SIM you want in it. That's it.

So first I need to boot with a Verizon SIM and then power off and put the Movistar sim?

Hello,
Once I put my Movistar Sim, I receive a message "Sorry your device can´t be activated on another carrier´s network right now. For help, contact Verizon at ....."
Any suggestion?
Thanks in advance!

I honestly thought this guy was going to Mexico to pursue his career by becoming a movie star.

Hi,
An update from unlockunit.com:
Hi Hackerjj,
Unfortunately, if you cannot find your Phone Model, Country or Network listed on our website, we are unable to generate the unlocking codes for your device.
If you get the message ‘’Unavailable’’ after entering the order details on our website, one of the below situations may occur:
1. Your phone is locked within a CDMA and not a GSM network (you can check on www.gsmarena.com if your phone is a CDMA model)
2. Your phone is not part of the networks/countries that we currently unlock
In order to receive the correct unlock code, it’s very important that you select the correct country and network you originally bought your phone from. In case you place an order with the incorrect order details, we will not be able to refund your payment.
We are constantly improving our service and we hope that very soon we will start to offer unlocking codes for devices locked to Verizon, U.S.A. such as yours.
Thank you for your collaboration and we apologize we couldn't help you this time.
Have a great day!
Kind regards,
Ionut Z.

I don't believe it would change your IMEI.

It needs an active Verizon sim in it for 24 to 48 hours before it will umlock. Once unlocked it should receive a message saying so.

not true.. i never understood why people will come in here and trust anything anyone says when it comes to sim unlocking lol..
verizon unlock policy states to prevent theft/fraud users are required to activate the device with verizon then after 60 days the device will be unlocked..
if his verizon purchased g975u was never activated on verizon then he hasnt even started his 60 day wait period.. verizon specifically implemented this policy because of people doing what the op is doing... purchase a phone for cheap somehow then use it on some other carrier/network without ever using verizon..
i am sure they had lots of theft and fraud going on with users scamming vzw devices for cheap then reselling for profit since they were unlocked theyd work anywhere out thebox so thisis their way of trying to combat that..

Thanks! I had bought a Verizon Sim, it is on the way, I think I will receive it in 2 weeks, after that we will know it the cellphone is unlockable. This is the last thing I can do, I think this cellphone is un-rootable also a pain. Another way is to use this provider, but I have not completely trust and is very expensive. https://store.unlockboot.com/remote-unlock-service/
