Hello! I have an unlocked Galaxy Nexus on the Bell Mobility Network in Canada, that I have a US T-Mobile prepaid SIM card for traveling in the States, and getting cheap data: yay for $3/day unlimited talk, text, and data! I was away a month ago, and just noticed today, that I was unable to send picture messages. The phone said to check my APN settings, to which I said, "Wtf does that even mean?" and googled it. Upon figuring it out, I checked the settings, and it still had my T-Mobile info in there, not my Bell settings. I changed it, and everything is hunky dory, nbd.
My question is, why didn't it automatically change, when I got back to Canada and put my Bell SIM in? Also, when I got to the States, I had difficulty joining the T-Mobile network. It was stuck roaming on AT&T and I couldn't access data. I had to physically make it join the T-Mobile network, by going into the mobile settings, hitting network operators, and selecting T-Mobile from the list. I happened to figure that out on my own, purely by accident. I didn't have to do that, when I originally got the T-Mobile SIM during black Friday. I just popped it in, and it worked. My Bell APN settings were fine upon returning after Black Friday too. Does anyone know why the issue this time? I was only running the previous version of Jellybean back in November, the phone has since updated to new Jellybean, could that be why? Or is my phone crapping the bed?
Thank you for any input :0)
PS phone is unrooted and running stock Jellybean 4.2.1
I rooted my Spring Samsung Galaxy S6 (SM-G920P) running Android 6.0.1 and I unlocked it. I want to use it in my local CDMA network, but when my phone company activated it along with 3G strangely I have signal (i.e. can make calls or send SMS messages), but my 3G does not really work. 3G only comes up for a few moments (as seen at the top bar) when Hands Free Activation (HFA) is trying to work (it eventually fails), or if I go to "Activate Device" in my setup it comes on for a little while too and then goes back off. If I disable HFA then 3G never comes on at all. Why can't I disable HFA and keep 3G connected?
Also, if I take out the Spring SIM (which is useless here since we do not have Sprint here), it tells me I should insert a SIM. Why is it requiring a SIM if I have my preferred network set to: CDMA?
I am really bummed about this after all I have been through, there must be some way to have it not require a SIM and not require activation for 3G?
You need the proper apn setup for your carrier. You should also get a sim card from your carrier, if they use them. If not, try taking out the sprint sim and doing the uicc unlock.

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.
Hello everyone,
I'm having a bizarre problem that no one can seem to fix. I have an unlocked AT&T branded Note 10+. I used it on my preferred service, MetroPCS.
A couple of weeks ago it stopped receiving or allowing me to make calls. The signal showed full bars and everything else worked fine. After attempting to fix it and failing I switched providers and went to Verizon.
Bizarrely, my phone will not work on prepaid vzw but did work on a post paid so I signed up. Everything phone related worked. It was however very expensive.
Seeing my phone work on a network made me think my phone wasn't the issue so I went back to my preferred network.
Now the situation is this: With a metro sim inserted I show 4G LTE icon but no bars, instead it's just a circle with a line thru it. In this state I have full data but now calls and texts don't work. When I try to make a call the 4G icon disappears and full signal bars replace the circle with the line.
I tried metro tech support, they are no help at all. So I called Samsung. They informed me that my device is still locked. That can't be true as I've used it on two networks that weren't AT&T. However, rather than writing them off I went back to VZW and had a worker insert his sim into my phone and it worked flawlessly, just reassuring me that my device is unlocked.
This device, other than being unlocked is unmodified and had been used in a 100% stock state. Is there anyone here who can please direct me to a solution for this issue?
Edit: I have tried switching to new metro sim cards. Reset my apns and network settings. I even tried a full factory reset.

You just proved either the SIM or the account is the issue.

I would agree. I should've included that I have tried 3 new metro sim cards, with the same result.
However, please tell me more about how this could be an account issue? Because that could lead me down a path to a resolution. Thank you
So I have the Galaxy S9 plus, sprint edition. I flashed it with the U1 firmware. Then paid to have it network unlocked. It was reading every SIM card, but sprint & boost (bcuz to get are n not compatible with the unlocked SO/S9+.
So, I decided to switch to either Verizon or AT&T. Verizon won it due to the year long Subscription. Anyway before I went to Verizon. Every SIM card I placed in the card worked no problem. Well, Verizon activated the phone told me the steps to do. I powered off the device. Like I was told & placed the new sim card in.
When I booted up my device it, rebooted with the "New Network provider Sim inserted" & did so. It came on with service. Then rebooted again & came back on with service... Yet again. Then out of nowhere it rebooted, but this time it came on with it any signal bars. Saying, the folowing messages "Searching For Service", "No Network Connection" and "Emergency Calls Only".
I have did all the trouble shooting that I have came across. Including using the Chimera Tool to try & fix the network connection. But it repeatedly failed. I took it to UbreakIFix & they said the phone's fine. That it has to be Verizon's side with the problem. Can anyone help me fix this issue.
I have placed other Sim cards into the device & they work but not one Verizon Sim will.

some steps would include making sure its switched to global mode in network settings and setting up the apn
