hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
I'm from Sri Lanka and just bought a Galaxy s4 mini duos from a online seller.
There was a label on the retail box saying this phone works with American SIMs only.
Yet the seller mentioned that the phone will be unlocked.
The phone seems to be unlocked. No questions asked when I turn on the phone with local SIMs,
From the two SIMs the one selected to WCDMA mode works fine while the other one which has no option but to work in GSM does not get registered in network. I tried manually selecting the network. It shows a list of available GSM networks but fails to register when the required one is selected. On the other hand when I interchange the network modes on the SIMs the former one which worked fine in WCDMA signals, fails to register on GSM network while the latter one which failed to register with GSM mode, registers and works fine in WCDMA mode.
The SIM selected to work in GSM only mode, shows no network or Emergency calls only.
So the summery is phone does not let the SIMs to register with GSM network but allows for WCDMA network of the same operator.
I also checked, GSM reception is good in the area. Tried several other SIMs the result was same.
As the phone only allow one SIM to use WCDMA mode at once, I'm stuck to using only one SIM in a dual sim phone.
I'm thinking to return the phone. But before that would like if anyone here can help me with this issue.
Can it be due to a unlocking problem or should it be a hardware failure?
Thanking you in advance
Hi All,
I have a Canadian T989D from Koodo mobile which I unlocked using unlock code. I took it abroad to Pakistan and after using for 6 months, one day all of a sudden I got NO SERVICE.
Trying to manually select networks, I come across different networks available but clicking on any one of them results in NETWORK REGISTERED sign but still doesn't connect to any network. When I go into the APN settings, I can see different APN settings for the respective sim cards that I put in. E.g. If I put UFONE sim card in, I can see APN settings for UFONE SERVICE PROVIDER.
Here is the twist though. I came back to Canada yesterday and when I put any Canadian Sim in it (FIDO/VIRGIN), it connects to the network without any problems.
Next, I tried T-Mobile sim in the phone. At first few attempts I would receive NO SERVICE/EMERGENCY CALLS ONLY messages. However, just recently I was able to connect to the network by repeatedly changing sim cards and restarting the phone.
So the specific questions to all of you is that "Why can't I connect to ANY network in PAKISTAN when I can see the APN settings for each sim card I put in?" Is there something I can do to fix the issue? I have a running sim card from PAKISTAN with me which I had previously used to connect to the network. Please help/guide me.
Any response will be greatly appreciated.
I've got my unlocked S9 from Samsung. I have a Redpocket CDMA sim card, which works fine in a Samsung S7E and a Google Pixel. However, when putting this sim card in S9, the S9 could not get on its network. It shows Emergency calls only and "Not registered on network" when making a call.
Sometimes it shows "refreshing sim card data" and no network. When turning to network modes, it says "LTE/3G/2G" etc but redpocket cs seems to believe the right one should be "LTE/CDMA" instead, which is not in the list.
I tried various usual ways such as factory reset etc, which did not change anything.
I tried a project Fi and a verizon sim card in the S9 and they were recognized with no problem. Thus I think the S9 is not defective.
I did some searches and people mentioned S8 had the same issue too: https://forum.xda-developers.com/galaxy-s8/help/unlocked-s8-failed-to-register-red-t3736850
I am wondering whether anyone has this problem or a solution.
Will flashing to verizon firmware help?
Thanks.
I'm having the same issue with PagePlus! I just put the SIM from my VZW S6 into my unlocked S9 and when that didn't work I chatted with support to do an ESN change (I thought perhaps PP needed to do something on their end). I was told if there was no "LTE/CDMA" option that the phone wouldn't work on PP.
I tried using an app to switch between different network modes (including the LTE/CDMA/UMTS auto which my S6 uses) to no avail.
I'm tempted to try flashing the VZW firmware, but the post here makes me wonder if it will accomplish anything.
I tried that APP to force network mode too but it did not seem to work.
As an update, Redpocket customer service is really great that they moved my number from Verizon network to their GSM/ATT network, and everything works fine now. I do not want to try flashing verizon firmware for the same reason...
Too bad Samsung could not get such a simple thing right.

Can we sue them?
I faced the same issue too. Apparently, Samsung does a setting update that prevents the sim from registering for Verizon's MVNOs. I called them and they said they NEVER heard of this issue. Apparently, you all did too. I am tempted to sue Samsung for this since this could be an antitrust issue. They are preventing competition by working with Verizon and feigning ignorance.Can any of you comment on this?
I was going to go with one of Verizon's mvnos. And their SIM card would not work and I did not realize it until I spend the $40. I had to put an actual Verizon sim in my unlocked phone to use the Verizon network. So either Verizon is blocking the S9 on mvns or the mvnos don't have the updated information for the S9. Total wireless told.me it Had to be a Verizon branded phone for it to work. So I think if someone flashed the Verizon firmware on the unlocked version it probably would work.
i dont see anywhere on the post where you contacted the MVNO provider, to register the ESN or IMEI of the device.
Also does this MVNO even allow BYOD?
i remember I had a line from Cricket or Metro that had a sim card, it worked on my Nexus 5x, however inserting it to another nexus 5x, it didnt work, I had to call them to register my IMEI
Hey guys this is an old thread, but maybe this will help someone. My old Red Pocket SIM would not work on the S9, but my renewal came with a new SIM, ending in 8222-15XX (old was 8180-50XX) For ****s and giggles I put it in and it showed LTE/CDMA and verizon. Had RP CS switch my active SIM and now it works with no workaround!
TL;DR Try a new RP SIM if you are using one a year old or older.
I also have similar issue.
Where I used to get lte over voice, but no longer getting after a recent update from samsung. Using Redpocket cdma sim
Now I have lte and voice, but dont get lte over voice even though redpocket said they have enabled Volte on my line
We just added an Unlocked Galaxy S9 (replaced S5) purchased from Amazon (Black Friday sale), ordered new Sim from Pageplus (MVNO using Verizon ), called them to transfer the phone number, popped it in and the S9 configured itself for Pageplus, and everything works perfectly...

That's great news. I switched to GSMA due to CDMA issue. I will switch back to CDMA after my current plan expires.
I heard that RCS (messaging via wifi connection similar to imessage - samsung messages app supports it in pie I believe, not sure about oreo) is active in verizon now including mvnos. Have you tried it?

I tried for my unlocked note 8. For the new sim coming from red pocket, it works great at the first time. But later when I switch the sim to a GSM sim for international travel and then switch the sim back to the red pocket sim, the same problem appeared. I have to use verizon sim to get LTE/CDMA back in the emergency mode.

Traded in my S9 with an S10+ and the redpocket CDMA sim works now!

I think you've found the answer for those who are unable to get their existing RP SIM to work on the S6-7-8-9's running OREO or PIE. I just took a later serial numbered CDMAV SIM (89140000018821472XX), inserted it into another S8+ that I have, booted it and saw the Verizon Wireless scroll across the top. I'll chat with RP today and see if they will switch the ICCID numbers between old and new.
After countless hours looking into this problem, I tip my hat to you for the solution provided.
Try as I may, in the end it didn't work for me.
It worked for me when I flashed the latest un-branded U1 firmware G960U1 UEU6CSI1 via the patched Odin, from:
https://updato.com/firmware-archive-select-model/?record=E68EDDB6DBFB11E99E59FA163EE8F90B
I've also done a full factory reset from recovery after the flash.
I guess they must have fixed it with the latest firmware updates... ymmv
Since the August update, both of my Verizon branded S8+'s work directly upon inserting a RP sim card.
POSSIBLE SOLUTION!! (YMMV)
I had a similar problem when I upgraded to Android 10. I no longer had CDMA as a choice for Network mode. Here is the solution that worked for me:
Step #1:
Go to the phone dialer and dial *#*#4636#*#*
This will bring up a new screen
Select "Phone Information"
You will be greeted with a scary-looking screen with lots of stuff
Scroll down and look for "Set Preferred Network Type"
Select "LTE/CDMA auto (PRL)" from the drop-down
This will give you phone service... but not data.
STEP #2
To get data services, you will need to create an APN.
Go to settings/connections/mobile networks/Access Point Names
Click on add and enter the following:
APN Name: Verizon
APN: VZWINTERNET
MCC: 311
MNC: 480
Authentication Type: None
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6
I found that this APN worked for me... (YMMV)
Hope this is helpful...
are you folks still having trouble with this? it doesnt seem like a difficult obstacle to overcome
Thank you sooo much! Creating the APN did the trick.
I unlocked my VZW g6 play by entering code in settings section to unlock phone (did not insert AT&T sim and wait for code request). It said code accepted but when I put in my AT&T sim I can't connect to their LTE network. It reads the sim, switches to global (gsm), and my network says AT&T with the proper phone number for that sim... But no 4g. I tried inputting the APN settings I found on several sites.. No luck. Same when I copied the APN settings from another AT&T prepaid phone I had available. No go. I called and asked for the APN settings from AT&T and they said I need to change the IMEI number on my sim to that of my g6. They said they did that for me. After power cycling the phone as instructed I still have no data service. Anybody have an idea what settings I need to use in order to use my AT&T sim? Or is that even my problem?
