The search function here on XDA or Google. Both will bring you to the answers you need.

I would try fasgsm.com or call your service provider for the unlock code cause the free hidden menu unlock method don't work for everyone. However the free method did work for me

Network Lock

Hey there
I recently scoured the xda site for instructions on how to remove the network lock (Currently Three,UK) from my SGS4 GT-i9505.
I came accross the *#0011# method posted here
http://forum.xda-developers.com/showthread.php?t=2282683
I have followed the instructions to the letter but cannot get past stage 4 (press menu, press back and your at the main menu of service mode) well the screen doesn't change and there are no menu items i can select i.e. the UTMS section i need
If any one has had similar problems or knows of a solution it would be greatly appreciated.
Thanks

Just found our answer...see las post by me...
Second option is to phone network (in my case Three), they told me i have to have the contract at least 1month then i can pay £16 for the code to unlock the device

[Q] Mobile Network State Disconnected

I'm sure this has been asked before but I am finding nothing about it in my search so I'm asking for help here. I will attach a few screens to show my dilemma. I'm stuck on mobile network state disconnected. I am pretty sure my APN settings are correct. I am rooted and running Slim Bean build 8 as well.

Your mobile network state will always be disconnected while on wifi, OP.

Go to your APN and hit restore to default. Reboot and let it sit for a few minutes. Report back.

im on a gt9500 and tried this, but did not fix it for me. I have the issue while on GSM, WCDMA works fine.
Your phone doesn't come with default apns it is international. It reads the SIM and puts the generic APN settings in. You likely need to manually Input them

I had this problem on my Canadian Telus 9505 S4.. I tried the things in this Thread, and it didn't seem to work. What I ended up doing was downloading an application called "Tweakker" and it automatically detects your APN settings for you to enter manually, I did that, and then rebooted and it seemed to work for me. Hope I Helped somehow.

I'm confused, you did flash a custom ROM right? If so it was for the right phone version right?

Go to connections--more networks--mobile networks--access point names and there you must have something.
If it's empty you have to manually create one. Hit menu then new apn. And for the correct values do a search for your carrier apn

note 3 msl app
There's an msl app floating around in the note 3 forum that works for the s4(no not getmymsl or terminal emulator). It gets your msl by pressing ##3424# for the note 3, in the s4 you just press the retrieve button and your set. also in the *#0011# hidden menu in the cdma section, it gives you an option of changing the msl. I tried changing mine to all zeros but instead it changed it to 000083. Oh well, hope this helps you.
Thanks will check it out

Tablet SIM on galaxy s4

Hey guys, I have quite an uncommon question. I searched all over and couldn't find anything.
Can I take my tablet 3G sim card and connect it to my smartphone for Internet access?
Thanks.
Sent from my GT-I9505G using xda app-developers app
Should be able to, but phone calls and texts might not work if it's a data only Sim.
Sent from my GT-I9505G using Tapatalk
Yeah but that's exactly what I need. Cause I have an iPhone 4 that I use for texts and calls, then I have my sgs4 gpe that I use only for data. Thanks
