BTW you should post in Galaxy Note 2 Q&A forum ( use xda device search engine to locate it)
A modem change might give you results only after you have checked your APN ,
Quick Guide
First Check your settings > about phone > status > your phone number ( IF UNKNOWN )
You won't be able to send SMS by any third party sms apps or Have a Network connection
Solution :-
You need to edit that "unknown" number to your phone number, by putting your SIM card on any old phone that has a "my number/owner number" option, (most old phones do). Edit and save it to the proper phone format as your Sim Card number (Example: +63913XXXXXXX). Now put the SIM back to M110S, to solve this problem.
Than check your system settings, in Settings > Wireless & Networks > Mobile Networks > Access Point Names.(APN) as provided by your Network provider . If your Apn is not set, you wont be able to have data connection, so set it first
If still no data connection, Common Trick is to toggle WIFI and Airplane mode or
1. Turn ON WIFI
2. Set the phone to Flight Mode
3. Power down the phone for a few Minutes
4. Power it back up
5. Turn OFF flight mode
6. Turn OFF WIFI
Should get Data back

Is there a way to unlock 5.1.1. OH1?

I already have root and have tried idones app to unlock, but for some reason, the unlock seems not to be working. The app says the phone is unlocked but when I insert a GSM sim card into the phone, it doesn't get any signal and the hands free activation loops. I was advised to go into settings -> mobile networks -> GSM, but the mobile networks setting disappears when I put in a GSM sim. It comes back if I put my Sprint sim is put back in. I also select GSM on that while my Sprint sim is in but when I take it out, that menu disappears. Is my phone unlocked or is it still locked? If its still locked, what steps can I take to unlock it given my current build and android version?

Idone should b able to help . Go to dialer, dial *#0011# ,
then in service mode press menu > back , then press menu > key input and type "Q" and press enter.
Then press menu > key input and type "0000" thats zero , 4 times .
The rest im copy n pasting from "jayfi" post iver at the us cellular forum
* - UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN
* Change preferred network type to LTE
Let me know if you need clarification. I don’t have the phone in front of me currently but am pretty certain that is everything.
^^ after ding this itll go straigbg to gsm connection and bypass the cdma network. Let me know if you need help.

I have done all the steps up to 0000
After all those steps, the Service Mode Menu still looks the same, how do I get to the "UE Settings and Info"? It's not in my settings menu

Sent you a shortcut in pm . Let me know if u need help .
