[Q] phone always in roaming

I just bought a used DINC2 with the intentions of using it on Page Plus. I've factory reset the phone and it's running stock Gingerbread 2.3.4. I've noticed that the phone is always showing the roaming indicator. (I currently use an LG VX5500 flip phone on Verizon and it is never in roaming.) So, I've tried dialing *228, option 2 to update the PRL as I've seen mentioned but it's always unsuccessful (it dials but then comes back with a message that it was unsuccessful - probably because the phone isn't currently activated). I'm afraid to activate service on the phone if it has a problem and I can't call Verizon support to help because it's not activated with Verizon. Will activating the phone likely fix the problem? Any suggestions?

So the phone isn't activated but you see the roaming symbol because possibly it's trying to find an active Vetizon signal. Once activated n it knows the signal I'm 94.6% sure it won't be roaming anymore.
Sent from my forgotten by HTC Droid Incredible 2. Kept alivw by great minds at XDA that haven't forget this phone.

I went ahead and activated the phone with Page Plus and roaming is gone now. The phone must have lost it's programming because when I activated it, there was a list of things that got programmed (including the PRL). I activated another phone and it didn't do any of that on activation. Anyway, long story short, activated the phone and roaming is gone!

Network Connection Issue

I've been using an S4 for about 2 weeks now, no problem. Last night I realized a text I sent never went through, and today my lock screen says "No Service" or "Searching" (despite the device showing full signal). I can't send/receive calls or texts, and I don't use a data connection. This SIM is also new (~2 weeks), and the device is neither rooted nor running a custom ROM. I've tried everything I could think of, like:
reboot
pull battery and SIM
confirmed APN settings on t-mobile site
tried alternate, non-"LTE" APN (epc tmobile com)
tried every network mode setting (GSM, GSM/WCDMA, etc.)
reset APN to default
turned on mobile data connection
manually scanned for networks (wouldn't connect to AT&T or T-mo)
select network automatically (wouldn't connect)
complete factory reset
I tried my SIM in another T-mo phone and it works; tried a different SIM in my S4 and it doesn't work. All other T-mo phones in my household are working fine. My S4 is definitely the problem here, but I don't see how the radio would just stop working after 2 weeks.
Has anyone else experienced/seen this? I never have, and it's driving me up a wall. I'm going to try my local T-mo store tomorrow, but I was hoping to fix it before then. Any help is greatly appreciated.
EDIT: I purchased the phone new on ebay. For a minute I thought the seller might have reported the phone stolen, but I checked the IMEI and it's clean.

Ive experience this but my service came back in about 25 minutes I did reset reboot battery pull sim pull it just came back on its own
Unrooted Samsung Galaxy S4 Up and Running
Rooted Mytouch 4G Slide retired
Rooted T-Mobile Sidekick Touch Obliterated
Rooted Mytouch 3G Slide Lost
Rooted T-Mobile G1 Dead

So I finally got to T-mobile today. Unfortunately, my hunch was right: the IMEI is blacklisted. Their in-house system must be more up to date than their web IMEI checker.
Time to solve this issue elsewhere.

[Q] Lost Sprint Cell Service

I recently rooted my LG G2 LS980ZVE using Stump. All worked and verified root access. Was fine for about 2 hours, and then I no longer have cell service. Apps regarding Sprint Zone, Sprint ID, Sprint Connection Optimizer are gone, and I did not remove them. Just rooted the phone. Everything else works fine. Go into Software Information under "Baseband version" click on it, nothing happens. Click on Activated Device, and get "Sorry-we experienced a system problem during your task. Please dial *2 from your Sprint phone or call Customer Care from another phone." Does anyone know what's going on, or what I did?
Thanks, Mark

At&t Note 5 Emergency Calls Only after flashing to Marshmallow

Hi guys can you please help me with this?
I bought my note 5 off craigslist and it was currently on G920AUCU1AOJ1
This security notice wouldn't stop notifying me ect common error I guess when they first came out. Solved by getting app disabler.
I really wanted to get the marshmallow update, I tried OTA says it was fully updated.
I then flashed it too N920AUCU2APB2 Then I noticed it was saying emergency calls only when I tried to call someone. I just continued to flashing to marshmallow.
Now I can't even find a downgrade firmware back to my original state to get the phone to even work again! everything else works but when I looked in to about my phone
SIM card status it says Network Unknown, signal strength -113 dBm 0 asu. Mobile network UMTS, Service state out of service, Roaming Not roaming, mobile network state Disconnected.
I believe the guy I bought it from knew all this and that's why he took it back to a stock firmware.
Can someone please help me out with this? I can't even find the stockware to take my phone back! Either I would and the links broken or its for a different carrier.
