"Invalid SIM" - first hand experience while outside the US - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

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"?

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.

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.

SIM card is not from Verizon...

I bought a Verizon unactivated HTC 10 recently, for my AT&T SIM card (AT&T is not selling HTC 10, and I have a Best Buy gift card, so I had to buy either Verizon or Sprint. Verizon is cheaper.)
The AT&T SIM card works just fine, but there's an annoying notification saying that "SIM card is not from Verizon..." that won't go away.
Other people online (using different phones) suggest disabling "activation manager", but no such app exists.
I already disabled & force stopped any Verizon/Amazon apps.
Does anyone know how to get rid of the notification?
sim unlocking service like this http://www.htcunlockingservice.com/htc-model-unlock-code/htc-10.htm ? there is other companies also. I have no experience with any.
Use any SIM on any GSM Network
With an unlocked HTC 10 you can change carriers without buying a new phone. This means you can take advantage of the best service package for your current needs. Then if your needs change, you can change providers any time.

Or try calling Verizon and see if they'll give you your SIM unlock code for free. They did it for me a few years back when I was preparing for some international travel, but I am also a long-standing customer with a good history on Verizon.

FYI, all of Verizon's postpaid LTE phones have been SIM unlocked since ~2012, including for GSM usage both in the US and internationally. No SIM unlock is needed for the Verizon-branded HTC 10 or any other modern Verizon postpaid LTE device.
It's totally normal for a Verizon ROM to state that an inserted SIM is not a Verizon SIM, it doesn't affect usage of that non-Verizon SIM.

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.

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..

Here was the first phone that they set up in store

Sprint V20 users. Don't waste money on unlock scams

From personal experience i can tell you that anyone claiming to unlock your phone is scamming you. I had to get my credit card involved to get my $20 back. There are those that will GSM unlock with a computer but the moment you update your FW you'll lose that unlock.
Sprint devices NEVER unlock with a code. If you have a fully paid off device then Sprint will have to legally unlock it for you. You chat with their international team for some reason to get this done.
It's easier if you have a phone active with Sprint. Do not waste your money elsewhere. FYI.

Try this as it may work. Make sure the GSM SIM card is "live". INsert the GSM Card. Go into settings and System Updates. Update PRL, Profile and then UICC unlock. I had to do it on one of my V20s as Sprint instructed and it worked.

Make sure you have enabled "Developers Options" and set the "OEM Unlock" to "On".
The only way you can truly unlock it is with the UICC unlock. Are you a Sprint customer? That helps. However if you are not and you phone is still fully paid off, go on the following website and initiate a chat:
https://sprintworldwide.custhelp.com/app/chat/chat_launch/
Tell them that you HAVE TO get it unlocked and ask them to reset and refresh the unlocking process from their end. I had to do this with an LG X Power. They made me wait for almost 10 minutes after which my phone rebooted by itself after they reset it. Once I restarted the phone and connected to wifi, I was able to UICC unlock it. Good Luck!

That is BS on Sprint's part. I just helped my niece UICC unlock her V30 literally yesterday using that same link I provided. You have to keep trying and be patient with them.
Also, being a "current" Sprint customer helps. I just tell them I have to travel to places where Sprint offers spotty coverage and I don't want to lose my customers. YMMV!

Spotty coverage isn't even a lie for me. I had a couple sprint phones. My house is in a absolute dead zone and my whole area is spotty at best, unless im smack dab in the middle of town not one bar. Im on the west coast and looking at theyre coverage map their network is almost non existent.
I don't have a sprint account period though. My other phones were on Sprint mvnos and like i said i bought this phone used and obviously have no contact with the seller. Sprint wants account pin. I don't know why they can't just keep resending the signal until its unlocked.
I asked on their support forum and the rep said when the phone becomes eligible for unlock they automatically send signal to unlock it once. If the phone is roaming or off at the time they sent the signal your sol.

My unlocked Verizon S10+ is somehow locked

Alright, got a pretty wacky situation here. Trying to see if anyone has any ideas of how to fix this.
I bought an S10+ Verizon firmware from Swappa a few days ago. I intended to use it with T-Mobile. Good deal, good transaction, all good right? Wrong...
It was my understanding that most Verizon phones were unlocked and that I could just flash the Unlocked or T-Mobile firmware to get full T-Mobile functionality.
On receiving the phone I got a "This phone is locked, contact Verizon at etc etc" message. I shrugged and flashed it over to unlocked firmware, where I was met with an "Invalid SIM card. Network locked SIM card inserted." and "PIN to unlock SIM service provider" window. So the phone was locked. Here's my troubleshooting steps from there.
Contacted Verizon support online. They said they lock all their phones for 60 days now as of late July. I said I'd bought it used, they said it had been bought at Walmart recently and there was nothing they could do.
Contacted the seller. He gave me his proof of purchase that the phone was bought new from Samsung.com back in March. I used a site to check the IMEI and the phone was legit from March, and not reported stolen or sketchy at all. Samsung.com specifically says they don't lock their phones and it was well before the 60 day policy anyway.
Contacted Verizon support where they said the phone was purchased as a Verizon phone so it can't be used with other networks. I should sign up for Verizon to enjoy all the features of my phone ? ....and also have it activated on the network so it could be cleared and unlocked. Alright...
I took the phone to a Verizon store where they put an active Verizon SIM in it. Verizon SIM worked great, T-Mobile still had an unlock code. The employee was confused and said they've never entered an Unlock PIN before so he sent me to corporate Verizon support store they had nearby.
Corporate Verizon store was a ton more helpful and the guy called up their god-tier upper support guys. Those guys took over an hour fiddling with things and along the way determined that the phone and it's IMEI were all clear, not stolen, and unlocked. The previous owner had a clean account and was in good standing. The store guy said he'd never seen anything like this and in his four years he'd never entered a SIM pin before. They additionally made sure I hadn't accidentally encrypted my SIM with a pin (I hadn't) and that all the default Verizon 000000, 123456, and 111111 codes weren't going to work. They recommended I contact Samsung support.
Samsung support thought I was an idiot and said that all the phones sold on their storefront are locked and I should contact Verizon to get it unlocked. I tried explaining all of the above but it was like talking to a brick wall.
So what have I tried?
Flashed the phone from Verizon to Unlocked to T-Mobile to Unlocked firmware using Frija and patched Odin. Verizon firmware throws a "contact Verizon" message and sometimes a code window, unlocked gives me code window, and T-Mobile just says it's locked and doesn't give me anything.
I have tried Verizon, AT&T, and T-Mobile SIMs from my friends. T-Mobile and AT&T work for a couple minutes completely normally on reboot. Connection establishes, data, text, and calls come in. Then it locks up and doesn't work. Verizon SIM works entirely normally, but doesn't unlock phone even after being left in for an hour.
Going forward I am going to try
Ask the internet for help. I've googled the living daylights out of this problem and I can't find anyone in my situation. Help?
[\LIST]
Flash the phone back to Verizon firmware. Perhaps the unlock mechanism works somewhere in the firmware and only when it's connected to the Verizon network. Take it to the store, have them pop a Verizon SIM in for a bit, and hope for the best. Flashing from Unlocked to VZW firmware isn't working right now for some odd reason though. It's going back to TMB instead and I'm confused about that to.
[\LIST]
Figure out how to get non-incompetent support out of Verizon (though I've mostly gotten there already) or Samsung and see if someone can help me. When I had to unlock my T-Mobile S8 I bought from Samsung, the IMEI numbers weren't passed to T-Mobile so the regular support people said it was impossible. Eventually I got in contact with someone who broke me out of idiot-land and directly contacted a network engineer who solved the problem in less than 10 minutes. Maybe I can find a network engineer at Verizon?
I could use a sketchy SIM unlock website. Is there any not-sketchy ones?
There's an XDA thread for S10+ U & U1 updates by the mod ibowtoandroid. I believe he has an unlock service that's legit but apparently not cheap. If you read through that thread you might find information helpful for your situation. But if you post a question that was previously answered you will likely be told to read through the thread even though the person who tells you that could have actually answered your question in the same amount of time. It's not the friendliest thread but you might find your answer.
There is a lot of discussion about switching carrier firmware. Since your phone shows up as locked by Verizon even though it shouldn't be you might need to use a Verizon SIM for 48 hours before the phone will revert back to unlocked status--at the time your phone was originally purchased it was necessary to use a Verizon SIM on their branded phones for 48 hours before they could be switched to another carrier.
It's possible you got that message when you purchased your phone because the 48 hour clock started over for some reason but that's only a guess--the ibowtoandroid guy is far more knowledgeable since he actually has a business that unlocks phones.
Are you sure the person who you bought your phone from actually unlocked it before selling it to you? Even if the phone shows up as a device that should be unlocked the previous owner who had the Verizon service might have needed to call Verizon to verify the phone's unlock status before selling it.
Sometimes people accidentally relock these phones when flashing carrier firmware. It doesn't sound like you did that based on your description but if the previous owner flashed firmware to completely reset the phone instead of just performing a factory reset he might have accidentally relocked your phone on the software end.
based on wat ur saying the phone definitely seems to b carrier locked. I got an A50 from verizon and it does the same ecact thing..
theres services online you can use or some boxes have methods as well.. my tmo a10e for example was locked but chimera tool has a neat feature called carrier relock.. it essentially locks it to up to 64 carriers instead of actually unlocking the sim..
one thing i suggest tho is dont try to do it urself unless ur a seasoned expert lol.. i tried on a n976v and after a few harmless at commands it completely killed my imei and cert and mipi etc etc

Alright, got a pretty wacky situation here. Trying to see if anyone has any ideas of how to fix this.
I bought an S10+ Verizon firmware from Swappa a few days ago. I intended to use it with T-Mobile. Good deal, good transaction, all good right? Wrong...
It was my understanding that most Verizon phones were unlocked and that I could just flash the Unlocked or T-Mobile firmware to get full T-Mobile functionality.
On receiving the phone I got a "This phone is locked, contact Verizon at etc etc" message. I shrugged and flashed it over to unlocked firmware, where I was met with an "Invalid SIM card. Network locked SIM card inserted." and "PIN to unlock SIM service provider" window. So the phone was locked. Here's my troubleshooting steps from there.
Contacted Verizon support online. They said they lock all their phones for 60 days now as of late July. I said I'd bought it used, they said it had been bought at Walmart recently and there was nothing they could do.
Contacted the seller. He gave me his proof of purchase that the phone was bought new from Samsung.com back in March. I used a site to check the IMEI and the phone was legit from March, and not reported stolen or sketchy at all. Samsung.com specifically says they don't lock their phones and it was well before the 60 day policy anyway.
Contacted Verizon support where they said the phone was purchased as a Verizon phone so it can't be used with other networks. I should sign up for Verizon to enjoy all the features of my phone ? ....and also have it activated on the network so it could be cleared and unlocked. Alright...
I took the phone to a Verizon store where they put an active Verizon SIM in it. Verizon SIM worked great, T-Mobile still had an unlock code. The employee was confused and said they've never entered an Unlock PIN before so he sent me to corporate Verizon support store they had nearby.
Corporate Verizon store was a ton more helpful and the guy called up their god-tier upper support guys. Those guys took over an hour fiddling with things and along the way determined that the phone and it's IMEI were all clear, not stolen, and unlocked. The previous owner had a clean account and was in good standing. The store guy said he'd never seen anything like this and in his four years he'd never entered a SIM pin before. They additionally made sure I hadn't accidentally encrypted my SIM with a pin (I hadn't) and that all the default Verizon 000000, 123456, and 111111 codes weren't going to work. They recommended I contact Samsung support.
Samsung support thought I was an idiot and said that all the phones sold on their storefront are locked and I should contact Verizon to get it unlocked. I tried explaining all of the above but it was like talking to a brick wall.
So what have I tried?
Flashed the phone from Verizon to Unlocked to T-Mobile to Unlocked firmware using Frija and patched Odin. Verizon firmware throws a "contact Verizon" message and sometimes a code window, unlocked gives me code window, and T-Mobile just says it's locked and doesn't give me anything.
I have tried Verizon, AT&T, and T-Mobile SIMs from my friends. T-Mobile and AT&T work for a couple minutes completely normally on reboot. Connection establishes, data, text, and calls come in. Then it locks up and doesn't work. Verizon SIM works entirely normally, but doesn't unlock phone even after being left in for an hour.
Going forward I am going to try
Ask the internet for help. I've googled the living daylights out of this problem and I can't find anyone in my situation. Help?
[\LIST]
Flash the phone back to Verizon firmware. Perhaps the unlock mechanism works somewhere in the firmware and only when it's connected to the Verizon network. Take it to the store, have them pop a Verizon SIM in for a bit, and hope for the best. Flashing from Unlocked to VZW firmware isn't working right now for some odd reason though. It's going back to TMB instead and I'm confused about that to.
[\LIST]
Figure out how to get non-incompetent support out of Verizon (though I've mostly gotten there already) or Samsung and see if someone can help me. When I had to unlock my T-Mobile S8 I bought from Samsung, the IMEI numbers weren't passed to T-Mobile so the regular support people said it was impossible. Eventually I got in contact with someone who broke me out of idiot-land and directly contacted a network engineer who solved the problem in less than 10 minutes. Maybe I can find a network engineer at Verizon?
I could use a sketchy SIM unlock website. Is there any not-sketchy ones?

Hello!
Yes I did solve the situation! Here's the steps that I used to unlock my Verizon Galaxy S10+
I had changed the firmware to unlocked firmware using Odin and Freya. This was premature.
Verizon does not do unlock codes. You need to have the Verizon firmware on the phone, a Verizon SIM card from a friend, access to the Verizon account, and like an hour of spare time.
Pop the Verizon SIM into your phone, you can get them from a friend, convince a Verizon store guy to help ya out, or just pay a few bucks for a prepaid plan. The phone has to be on the Verizon network for this to work.
Call up Verizon technical support. Tell them you've got a phone to unlock and have been working with their Tier 2 team to square things away. You have to be transferred to Tier 2.
Important to note that Verizon has instigated a 60 day locking policy to prevent theft and whatnot on their network. If the phone was purchased less than 60 days ago and activated on Verizon's network than you're outa luck. You got to wait. If you don't fall under this restriction, you should make sure the support people understand because they'll assume that's what's happening... a lot.
The Tier 2 people generally know what they're doing. They'll verify the device's IMEI and that it hasn't been stolen, is paid off, and that your Verizon account is in good standing. They'll need the PIN access code from the Verizon account holder or a two step verification with another one of their phones.
Once they run the unlock process you should get a text saying the phone is now unlocked. Leave the SIM in for another hour or two to allow the process to complete. I removed the SIM shortly after on the first try and it didn't work so I had to do it again.
After that the phone should be unlocked and you'll be able to flash whatever firmware you want and use it on whichever network. I've got mine running Unlocked firmware on T-Mobile, works great
If you don't have a Verizon S10+ that's locked to Verizon I dunno where to start. Contact the mod ibowtoandroid on here if you get really really stuck. He can get it unlocked but it will cost a ton. He's legit though.

That was very helpful Thanks. I am pretty sure that my phone has passed that 60 days time frame and the device has a clean IMEI as well but I am not in the US. Do I have to be on the Verizon network or just a Verizon sim will work as well?

Its actually done through an android app modified by the carrier. The only way to get around it would be to have the carriers unique key as well as the private signing key so you could create your own version. Then you would need a way to modify the system image and successfully install it. After all that there's a good chance there's even more security server side. (Its Verizon, so you know...)
So yes, ultimately it isnt exactly possible.

Verizon needs to unlock your phone if you don't want to pay a third-party service. I don't think you need to have a Verizon SIM inserted for them to unlock the phone as long as it meets the necessary requirements.

I believe Verizon only unlocks automatically with a sim installed thats had service for 60 days(might be 30 now). I remember seeing someone say they put a friend's Verizon sim in and rebooted and it unlocked for him. I guess they dont verify IMEI to unlock just sim number.

I am outside the USA so no way to be on the Verizon network. I will however reinstall the original Verizon firmware and have some one call them for me. Let's see whether that works out or not. Thanks man.

Curious, how did you get a verizon device outside of the country?
To point out, this is the very reason Verizon changed their sim unlocking policy.. to help prevent fraud and theft as they would take vzw devices then sell them for profit to non vzw customers and theyd be unlocked..
Bcuz of this is why they implemented the device needing to be activated on the vzw network and a 60 day period before it will be unlocked.
I dont see them being able to manually override/bypass this as it is policy. That as well as most reps dont even kno the policy and will tell you its unlocked or "verizon doesnt lock devices" which is inaccurate lol

So any random Verizon sim thats active and has had service for 60 days or more will unlock it?
If thats the case someone could still make money off them by using there sim before selling it.

No.. i didnt say that lol.. its not tied to the sim card.. device needs to be active on verizon for 60 days.. i always use my same sim card that ive had for years now in my new devices.. i still had to wait 60 days for it to be sim unlocked..
U cant just pop an old sim in and have it unlock.. the device itself needs to be active 60 days..
When checking if a device is sim unlocked or not u dont put the sim number into the checker, u put the imei.. this is bcuz its tied to the imei/device.. not sim card itself..
What i dont know however is if you only need to activate it once on vzw network or if it needs to remain on vzw the full 60 days.. then again u cant use it on other networks until its unlocked anyways

A quick Google search you can easily find vzw unlock policy:
