[Q] Sim unlock on sch-i545 verizon samsung galaxy s4 - Galaxy S 4 Active Q&A, Help & Troubleshooting

So I was able to unlock my Verizon samsung galaxy s4 WITHOUT root. I downloaded an app called samsung service mode, which gives you access to the phones service mode which is blocked by Verizon software I assume. Once downloaded you can use the app to enable hidden menus the app cost 1.99. I tested it with a T mobile sim and worked. If you would like me to share the walk through in detail let me know.
But I would wait
Hear me out....
Anyways now that I unlocked it when I put the original Verizon sim text message and 4g service and data works but every time I make a voice call it says "mobile network not available" and when I call the phone it just rings. Any ideas?

Once again, this isn't the S4 sub-forum, this is the S4 Active sub-forum, a (near) completely different device - not just because it's water-resistant - in many respects.

[Q] Korean Made Note problem with AT&T data

Hi everyone,
Last month I bought a Galaxy Note (unlocked international version) for myself from Techno Trading House.
Before I received the phone I switch to ATT GoPhone from another provider. Once I received the phone I just switch the sim card to note and add the apn.
Everything working cool.
This phone came with default language of greek or polish, which i'm not sure. So i guess its European version. The phone says "Made by Samsung".
Then I decide buy another Note for my wife. From Techno Trading House. Like me my wife also switch to ATT GoPhone. This phone says "Made in Korea by Samsung". We set up the apn same like my phone and I can see 3g & H signals.
But the problem is the data does not work. When I open SpeedTest.net app the app force close 7 out 10 times. The other 3 times when I tap Begin Test, it will prompt message "Network communication Issues", "Try Again".
First I doubt it would be the sim, then we switch the sim, my wife's sim work perfectly on my phone ("Made by Samsung") and my sim had same problem in her phone ("Made in Korea by Samsung").
The only different I could see between this 2 phones is my phone say "Made by Samsung" (working perfectly) and "Made in Korea by Samsung"
(data not working).
Is anyone here having similiar problem? Or is anyone having Note which says "Made in Korea by Samsung"?
Hey, I had the same problem with galaxy S2, I don't think you are going to be able to have GoPhone data on your smartphone. What I did is I went to ATT store and replaced my sim (say that you forgot your ATT phone at home) and brake your existing sim. Try with new sim directly in your galaxy note! It should work but after some time they will turn it off because it is not a smartphone data plan! Cheers

But dude, I tried my wife's sim on my galaxy note and it worked!
I got data speed 1.3mb.
Her sim worked in my galaxy note and also on her old SE phone.
But her galaxy note does not work with her GoPhone sim and also my GoPhone sim.
retry apn
i would delete the apn in your wifes phone and re enter it as a new apn. make sure everything is the same as yours even capitalization. also make sure that gsm/wcdma is set to auto. hope this helps. if this doesn't work then maybe a factory reset would help. both sims work so there is something not set correctly in the phone.
may i ask what your apn settings are?
Wait where did you buy the note? Korean ver notes have 4g and is different hardware wise i.e. Not compatible to xda galaxy note roms. This is the only reason i can think of?

i have the korean version. i only get edge and i've tried every apn setting out there. 0.04Mbps DL 0.03 UL
made in korea and korean LTE note are different things
the made in korea for Samsung is a regular note with regular hardware. there is an Korean version of the phone with LTE.
i would delete the apn you have in your wifes phone, then insert sim , reboot then re enter the apn. make sure the use packet data box is checked and network mode set to auto. the gophone plans use GSM networks so turn it to auto just in case it isn't.
Delete the entire contents of the efs folder, reboot, you'll have data.
Make sure to save the deleted content somewhere.

[Q] Problems unlocking Galaxy Note 3

I just purchased a Galaxy Note 3 (SM-N900A), full-price, off-contract, from AT&T Wireless. I used an existing GoPhone (prepaid) account/phone number to activate the phone. The phone works (voice calls) with the AT&T SIM. However, I want to use the phone/device on aioWireless. I have a microSIM for aio. I have purchased an unlock code and followed the unlock instructions. I received a "Successful unlock" message after entering the 8 digit network code. However, I cannot make phone calls (or use the data plan) when the aioWireless SIM is installed. When dialing a number with the aio SIM, I get a recorded message that the service has been deactivated, and to contact AT&T.
When I try to verify whether the phone has truly been unlocked by typing *#SIMLOCK# nothing happens. If I then push the CALL button, I then get the message: Connection problem or invalid MMI code.
Any clues what is going on?

Do you maybe have to use different APN settings for the two networks?

I have no idea.
I would look up the APN settings for AIO and input those (Settings>Connections>More networks>Mobile networks>Access Point Names)
You could always just call AIO customer service or walk into a store and they should be able to help you out.

I thought APN is just for data and has nothing to do with his inability to place calls! especially that he is getting" service deactivated"
I would check the AIO account if its working first.

APN is indeed simply meant for DATA and MMS
Your phone is functional with TEXT message and CALL's WITHOUT even a single APN setting set up
The main problem here is compatibility. OR the SIM card
SOMETIMES you have to leave the sim card inside your phone for at least 5- 10 minutes
At one time it took me 20 minutes for a sim card to be recognized, then I got 4G
It depends on the network.
But if all fails, just call your new network and try to get a new sim card
As long as your phone is fully compatible, and you know it, there are ways around it.
Hope this helped!:good:
The *#SIMLOCK# and various variants of it no longer works starting from the GALAXY S3 and Above (Not even all S2's accept this code)

Verizon on Sprint Galaxy S6 Edge (SM-G925P)

So before anyone flames me for asking about using a Sprint S6 Edge on Verizon, I'd like to clarify that I convinced Verizon to add my IMEI to their database. I have voice, text and data access (but no LTE and always shows as roaming). My phone is carrier unlocked (obviously) and rooted.
Now that I've gotten that out of the way, here are my questions:
- How can I re-program my phone to recognize Verizon as the default provider? Or is there any way to flash the Verizon firmware on the phone (aka make the phone a Verizon phone)?
- I'm hoping to be able to connect to Verizon's Band 4 LTE since I understand the SM-G925P to have the Band 4 radio. How can I connect to it?
- I can't view/access the APN settings and so I can't manually add the Verizon APN settings because of some "profile does not have access" issue. How can I give myself access?
Thanks in advance!

Most Sprint phones have an unlockable bootloader so I would assume this one does as well. Why not flash a Verizon rom?

I'm interested to see if this works fully. It looks like all Sprint Samsung's can be sim unlocked and bootloader unlocked so this could be a solution to getting unlockable Samsung phones on Verizon once again.

Any update on this? I am in the same boat. I was able to add the Verizon APN's and I am still having the issue of not being able to connect to the 4G LTE. BTW the roaming icon on the phone I think is just the software being programmed for the Sprint network and sees that you connecting to Verizon as roaming. If you check the SIM status, it will show that it is currently not roaming.
Any updates on this?
Cpu
I've had the same problems that has bugged me for weeks. I used a app called COOL MASTER to cool my cpu and seems to have fixed my crazy phone

Can't Activate Note8, fails on configuration with Sprint & Boom Mobile

Hi Guys, I'm wondering if someone more knowledgeable can help advise. I've spent 12 hours and cant activate my Unlocked Qualcomm Note8 on any of my service providers (SMN-950U1.)
I want to use it on Boom Mobile Red (Verizon MVNO)
I cant get the Network Operator to configure, when I select Verizon it fails on configuration. I'm not referring to APN because I do not even get calls, the Operator is listed as "Emergency Calls Only". The Sim works perfect on my Pixel XL and iPhone 7 Plus. This phone was purchased unlocked form Samsung direct with clean IMEI. I called Samsung and they have no idea, they said the phone is defective, which I believe it is not.
I had an issue activating with Sprint and still have not had Data working, though I was able to get calls. I've given up w/ Sprint and will upgrade that line with a iPhone X.
I inserted my friends Verizon Post Paid Sim from his Moto Mod phone and everything was perfect (calls, TM, LTE calling) and the phone got LTE+. Is it possible the Note8 unlocked will only work with the big 4 carriers, ST and TW? I read a similar issue people from Boost Mobile have when they insert their sims it says invalid Sim. I really have no idea what is going on - Boom doesn't have many customers and their support team has never delt with this issue, they said the phone is defective. Has anyone been able to use a Unlocked Note8 on Boom? I've tried flashing various variants of firmware, including Verizon with no success. I'm puzzled with what is going on.

Problem activating on sprint

I purchased a used galaxy s10 G973U from someone who bought directly from samsung.com unlocked version. he used it with tmobile. Now im trying to activate with sprint and it wont let me. Network sim setting show that sim is unlocked. Im trying to activate my phone on sprint website and it says "This phone can't be activated
Sorry, but this phone can't be activated with Sprint service. Try to re-enter your IMEI/MEID or try another phone."
I thought this phone is supposed to be able to be used with both gsm and cdma network carriers. what are my options besides trying to return it?

Did you contact Sprint and get a sim kit sent to you? You'll have to do that and then it should work. If it doesn't after that, I'd initiate a chat with them through the support page on their website.
Another option is to go to a Sprint store to activate it. They will have the sim card available for it. Im using an unlocked model switching between carrier and carrier-free firmware no problem.
(PS, once you do get it working there's a way to enable hotspot support without it on your plan.)?
