Sim Unlock - Samsung Galaxy Note 8 Questions and Answers

Hi guys, I have a note 8 and it is previously sim locked thru a carrier back in my country. I have used samkey to sim unlock my my phone and it work like a charm using other sim card from another carrier however my problem is I can't use 4G LTE data using a different network but I can use it to call and text. When using my original sim from my previously locked carrier I am able to use DATA 4G LTE. I have searched for solutions in the internet but no luck at all. Please help. Roaming charges are very expensive and I really need help as I use the mobile internet for navigation abroad. Thank you in advance guys!

Maybe try with the new sim in your phone to reset the network. Go to settings - general management - reset - reset network settings. This will also delete your wifi passwords and such though. But I had a problem with my phone (N950N) to use with a different sim in it, that it would only connect to 3g, I did this and finally got LTE working.

Weird SIM unlock question

Hi,
I just unlocked my SIM card via a Verizon supplied code. I found an old AT&T SIM in my desk drawer - I called AT&T and confirmed the SIM is not active (nor has it ever been activated). I inserted it and the phone came up. However, if I use APN Manager, it shows I'm connected to Verizon. I'm able to make and receive calls.
I thought by inserting a different SIM I would be using that providers network instead of Verizons? Or do I need to manually change that somehow?
It's important I figure this out before my trip next month to Panama.
i think in usa the other network gsm bands are locked (so u wont be able to get service it wil just show no services i think) so even u insert them u wont be able to use that network ...
and u can change ur settings to gsm from mobile in network n settings i think..when u leave to panama or out of usa
hope it helps thnx

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.
as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.
Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks
Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

AT&T unlocked 2014 x not working on tmobile

I have an unlocked AT&T xt1097 but it won't register my T-Mobile Sim card. It registered for about 3 minutes, got a welcome to T-Mobile text and that was that. My phone number shows up in settings, but it shows I have zero service. I've reset, and rebooted several times to no avail. My sim works in a nexus 6 so it's not the sim. Imei os clean. Does anyone have any ideas what it could be or how I could get it to work with my T-Mobile sim?
When you say unlocked, unlocked Sim or unlocked boot loader?
sim unlock. As far as I know there's no boot loader unlock.
Could it be that the imei isn't in T-Mobile's data base since it's an at&t moto x?
Edit: went and put the imei in to tmobiles imei checker and it couldn't figure out what device it was and if it was okay to use on their network. Now I just need to verify with T-Mobile and see if they can register the imei.

did you ever get it to work? i am experiencing the same issue. it connects to my friends AT&T network fine but with t-mobile it just says "cant register" etc,etc.
Change the APN settings
I have had a problem like this with my unlocked phone and AT&T, but when they set it up in the AT&T store they fiddled with the APN settings. I had to do the same to get my wife's unlocked Lumia 635 to work on the T-Mobile network. Try the values used in the link attached and see if it works.

I was able to connect to tmobile network some times, able to make calls. No data connection at all. I played with APN settings and everything else. any help..?
I have an unlocked ATT x1097 and it works just fine with tmobile.
You just have to MAKE A NEW APN SETTING.
When you put a tmobile sim in it, it will automatically create a couple of T-MOBILE apn settings. Just leave that as is and create a NEW APN SETTING with same info you can find from Google. Select that as your data apn. And reboot the device for the best result. It should fixed the problem.
For those of you whose sim does not register into tmobile network; i think it could be one of the following reasons:
1. Original ATT modem does not work well with tmobile frequency in your area
2. The device is locked (stolen, non-payment, etc)
3. The device is broken
4. Your SIM card is damaged
As long as you are at the home screen with tmobile sim, your phone is GSM UNLOCKED, and it iwill never lock again.

Just wanted to say thank you. My T-Mobile SIM wouldn't connect and I even went to the T-Mobile SIM store to get a new SIM Card but it didn't help. As you stated, adding a new APN setting was the only thing that worked.
For those of you who want to unlock your Moto X, I purchased a code on eBay for about $8 and received it within 6 hours. I would post the link but I'm afraid it might be considered spam.
What type of data signal are you getting? LTE?

Nice. Where did you get your unlock code?
I don't know about OP but I have always used swiftunlocks and have had great luck. Got my N6 from ATT unlocked through them without issues as well.
http://www.swiftunlocks.com/unlock/motorola-at-t-tmobile-worldwide
I noticed that sometimes phone picks up apn without issues and sometimes you have to restart so I just restart every time I make a change to be on the safe side.
Just in case anyone else has the same issue as OP, you should use the
Code:
epc.tmobile.com
APN, NOT the
Code:
fast.tmobile.com
one.
The fast.tmobile.com one would not let me register on the network. epc one did immediately.

Hey, I know this post is kind of old but I am currently having the same problem with my moto X 2014 going from At&t to T-Mobile, were you able to get it fixed and if you did, what did you do?
Any luck? I've just come accross the same issue. Got phone unlocked, and bought a new sim and activated. I'll get like 3-4 minutes of service randomly here and there, but about 99% of the time no service. Tried multiple variations of APN settings that I've found online. No luck
Fixed all my seriously annoying connection problems by flashing the 4.4.4 modem.

I just gotta upload the 4.4.4 modem from my pc, will do that later for you.

Neither one works for data... Just got it unlocked from swiftlocks and I can get voice, but no data :crying:
Someone help!! ...plz
Anyone ?? T-Mobile reps are mostly useless, and keep telling me that my device may have been ' re-locked ' to AT&T after a hard reset !! I know that's not the case because I've thrown in a Vodafone sim and it recognized it ! The sim unlock was purchased from SwiftUnlocks and the phone took it in one try w/o any issues!
Now, I can't even get voice to work... All I see is ' No Service ' and when manually trying to register with T-Mobile, it says ' unable to connect to the T-Mobile network. Please try later '
Someone please help out!!

SM-N950W : Mobile Data not working.

Hello,
My note 8 cannot connect to mobile data. Whenever I activate it, nothing happens I don't get any mobile data signal what so ever. I also checked the APN's configuration with my Mobile carrier and they were unable to solve it.
It should be noted that my note 8 has a stock Canadian firmware and I am using in Morocco with a Moroccan sim card

did you check with your morocco sim does include data from your plan? Also which carrier are you using in Moroccan? it could be either your plan doesn't include data plan or the carrier doesn't have the UMT/LTE band for your note 8

Yes, I still have around 1gig of data available and My plan includes data.
My service provider is INWI and they do have LTE band since The same sim card worked on my previous J5 2016 normally.
I forgot to mention that, After activating mobile data and roaming, I checked the sim status in the setting where I found that Mobile network state is DISCONNECTED and Roaming is not running.

Can you test if you can make call or text? if so, i will suggest double check the apn. I checked your carrier in Morocco , you should be able to get HSPA data connection in Canadian Version Note 8(N950W) unless you select (LTE ONLY).

I can confirm that I can make phone calls and send texts without a problem.
I checked all options and none worked .
As for the apn, the configuration message was sent to me by my service provider itself.
I performed a factory reset that didn't help too.
Since you can make the call, I don't think it is something wrong with the phone. I checked there's only 1 hspa band and none for lte available for note 8 from your carrier. I guess either double check with the carrier for the apn or maybe the phone just can't pick the b1 hspa signal from your location.

I won't mind HSPA since there's not much difference between LTE and HSPA in Morocco. I doubled checked with my carrier today and they told me that I have to wait for 48H for them to look into the issue.
The weird thing is when I used an app called LTE Discovery I found that I do have a signal for LTE band 3 yet I have no internet.
It is mostly the service provider's fault, I think.

They might be similar to AT &T where they need to recognize the device IMEI number before allowing full data access onto their Network.

I checked with my service provider. Unfortunately, they don't need to recognize the IMEI number.
They tried to shift the blame to my phone saying that I might have a faulty device. It doesn't make any sense.

First thing I'd do is research and see if it's true what your service provider told you. It might not be. Second use another sim from another network in your device. Third borrow someone else's IMWI sim and use it in the note 8. Also check APN again.
Did the phone receive 4G or LTE prior to coming to Morocco with the same device?
I also don't fully understand on your earlier post about the phone status not being roaming. It shouldn't be roaming status if using a local sim card.

I still haven't tried another INWI nor another Moroccan sim card.
I have no idea whether or not it received 4G Before coming to Morocco since I won the phone from a Dbrand's giveaway. I think it's brand new.
Shouldn't roaming be active when you activate it in menu ?
I turned on mobile data roaming and nothing happens. Check the picture for details.
I turned off my Data Roaming and the Mobile network state remained the same - connected. I'd think " Mobile network state " has anything to do with roaming being on or off unless one is roaming out of their Network onto another network.

I turn them on and off yet their status remain disconnected. I understand why.
I really don't understand how to get mobile data working on my phone.
Hopefully someone else will try and assist.
In the meantime
On the phone dialer enter *#0011# and *#2263#
Also, the mobile network state will be disconnected if you are connected to WiFi.
Should get the following screen.
Also make sure that the correct APN is entered and active / selected.
Then try and go to the connections menu and toggle lte/3g/2g... to 2 or 3 g and back to to 4g to see what happens.
Also make sure Mobile Data is turned ON.
Go-to settings then search for Mobile Data.

That's weird as when I checked Frequency check website with device sm-n950W and your service provider INWI , it lists it as fully compatible. The other Moroccan networks were not though.
This would be the second instant whereby Frequency check has got it wrong. First being Samsung device I used to own.

I checked the frequency myself and I came to the same conclusion.
I was only told today by an INWI agent that devices from Canada and USA always face the same issue.
I triend orange which didn't work too. Gladly, IAM worked as it is the largest and oldest network in Morocco.
From now on, I won't believe what websites say till I see for myself.

MI 9/ network problems

Hello everyone,
I have Mi 9 M1902F1G 128gb with MIUI global 11.0.4. I am living in France and using Bouyuges telecom, recently when I come to work my phone loses network connection related to simcard. No calls, no 4G, no 3G nothing absolutely. There is a cross sign sometimes on network bar, then sim card activation process starts but no connection. Even I cannot send an sms. This is a new problem. I have been using this phone with same sim card for approximately for a year.
Thanks in advance

Change job
Since you don't tell us what actions you already have taken the most obvious is to pull out the sim card and clean it. If this doesn't help, contact your operator to get a new sim card. Everything you say indicates that your problem is one with the sim card or the operator and has nothing to do with the phone.

Have you tried with VoLTE disabled?
Also, by preferring network type 3G or even 2G, instead of 4G.
Maybe you recently got some some 4G/3G micro-station at work with the band not supported by phone
Edit: You could also try to inspect by Network Cell Info Lite, Net Monster, Net Monitor or similar apps available from Playstore
