SIM Toolkit for Android 2,3 - General Questions and Answers

Is there any working SIM Toolkit . apk for Android 2,3 ? I tried some ones but was not succesful . Thank U for answer

what kind of phone do you have?

I am owner of Samsung Nexus S 4G

Sorry for replying late, but if its for sprint. I don't think it comes with a SIM card slot; therefore, a SIM toolkit would not work on it. If its not for sprint and does have a SIM card slot, than try putting the same question on Nexus S Q&A thread, you'll get a lot of replies.

[Q] unlocking verizon s3

ok so i have already unlocked and rooted my verizon galaxy s3 using this guide: http://forum.xda-developers.com/showthread.php?t=2046439
everything is working fine however when i place a t-mobile sim card the phone says that the sim card i inserted is not a verizon sim card. can someone please point me into what i have to do next? i have a 16gb verizon galaxy s3 with 4.1.1 jellybean installed. i searched the verizon s3 forum via the search tool but couldn't find anything with my problem. thank you so much for all your help!!!
Your problem is that you have mistaken unlocking a bootloader for unlocking the SIM. Unlocking a bootloader means that you can now flash custom ROMs,kernels,mods,and tweaks.

SIM Unlock- Help please.

Hello everyone!
I'm writing for help from the experts. I don't know if this had been answered somewhere else but i looked all over the place and i didn't find anything for this phone.
After trying and trying for a few days now, i have not been able to unlock my verizon SGS3 so that i can use it with other sim cards.
I currently have it running on JB 4.1.2 it is rooted and the bootloader is unlocked thanks to the EZ- Unlock technique.
But when i put in a non verizon sim it says "sorry, this SIM is not supported. please....."
Can it be done ?
Thanks in advance
BTW: i've tryed the "galaxsim", and "Sim unlock" by chainfire as well as all the other similar apps i could find on the playstore but they have not worked for me.

Verizon S3 is sim unlocked for GSM, but not sure about the cdma. You can use it with t-mobile, att etc. There is a thread in android development forum about how to setup s3 as global phone. Try that one if you are using gsm.
Thanks doesn't hurt....

Hey !
Thank you so much for responding. I am trying to use it on a gsm network but it wont register, that's why i figured maybe its locked somehow. Also because of the message in the top that says non-verizon sim, it says sorry this sim card is not supported etc..
Where can i find the thread you mentioned?
Thanks again.
Go through the below thread to check how to setup the Verizon GS3 as world GS phone :

Ok so i worked on it till very late last night, and was able to do everything in the thread. My phone now shows the network apn in the apn list in the settings and i was able to get rid of the non-verizon sim message that poped up at startup.
But my phone still won't register on any network, I've tried to different sim cards and tried in global settings as well as gsm/utms auto or manual but it wont register onto a network.
What can i do ? Is it locked by Verizon or something ? Should i flash a different rom ?
Thanks for your invaluable help, i really appreciate it!
Have you tried using phoneinfo? Try using the phone info app to select preferred network type by going into device information. Find link below to the app. Try with different network type

If this doesn't work then try with lte sim card.
