[Samsung Galaxy Note 8 Questions and Answers] unextrapolating:
Hello, how are you? I rooted the Note 8 with the SamFailV2.5 files from [ROOT][SNAPDRAGON] SamFAIL for Galaxy Note8[V2]. The phone was a brand new out of the box unlocked SM-N950U1 and I inserted a Verizon network sim card to use the phone on my family plan. I'm able to make and receive phone calls, and receive text messages, but not send SMS or MMS.

I've tried to enter " *#5005*7672# " in the keypad, I've tried " *#*#4636#*#* " as well; one of them tells me "connection problem or invalid MMI code," and the other tries to call that number and I get an automated failed call message. I've been unable to successfully make a new APN. I can "create" a new one, but I'm unable to find it on the list after I "save" it. I tried to switch to 3g only and that made everything worse, I was unable to make or recieve calls or texts on 3g. When I switched back to 4g,3g,2g,auto I had the same problem and had to reset the network connections to be able to make and receive calls and receive text--but still not able to send texts.

I'm not sure what the issue really is, what are your thoughts? One thing that I want to try is to edit the message center number to 316540951000 for verizon, but I don't know how. Is there a console command I can enter to change it? Am I heading in the wrong direction? Please help!

I followed the root directions on post #3 it said:

" VZW Custom CSCFeatures thanks to [MENTION=2685386]louforgiveno[/MENTION]

ATT,SPR,TMO re-enabled callerID and spam protect.

DO NOT FLASH CSC IF YOU WANT CUSTOM FEATURES! "

So I didn't flash a Verizon csc. How do I determine which csc to use, or is that not what I need? When I ran Odin PrinceComsy.exe and tried to select the csc I saw the log say it failed and that it was the for wrong model. The other thing I'm confused about is if I need to re-root the phone with nand erase all, or if I can just flash the csc by itself. How do I access the custom features from the root directions: "VZW Custom CSCFeatures" and "DO NOT FLASH CSC IF YOU WANT CUSTOM FEATURES"? Would that have the solution to the problem?

I've gotten a new sim card and rerooted the phone since I posted the question. Calls work fine, 16Mbs download with 7Mbs upload for data, but texts are still a problem. I tried different apps. With the Verizon messaging app I'm able to send mms and sms, but the outgoing texts are delivered 5 to 6 minutes after the send button is pressed. Incoming texts are received in seconds. I can't understand why the Verizon messaging app actually gets messages to go out when default and top rated messenger apps can't, nor why it takes 5 minutes for outgoing texts to be delivered. I'm happy about this progress, but its not completely fixed.

Advanced Signal Status app will not display the advanced menu.

I would like to share that choosing option 2 after dialing *228 will make connection problems worse, it's the reason I had to get a new sim card. After the *228 changes it was impossible to connect to lte networks, calls and texts stopped working aswell. Tier 2 of Verizon tech support told me a new sim card was the only way to restore connectivity.

What information can I provide to help find a solution? Where should I ask for help about this?
