[Galaxy S 4 Q&A, Help & Troubleshooting] deeadox182:
Hey Everybody,

First off I'll start with what phones/firmware etc etc I have so that I don't need to be constantly writing it in the post.

My phone: i9505 W/ custom firmware, custom kernal etc (basically the custom phone of all phones...I'm a flashaholic...) 100% unlocked BTW

My bosses phone: i9500 W/ Omega v10? It's the latest Omage but I'm not too sure as I don't hang around the i9500 forums.. His is also 100% unlocked.

The other day I did some researching and looked into the 'Boost Mobile with Telstra SIM'....Glitch? I guess you could call it that?

Well anyway, I finally went ahead and did it.

I went up to Telstra and picked up 3 blank SIM's, one for myself, one for my boss, and one for spare.

I ported my number to one of the blank SIM's and, when I went to turn my phone on it came up with 'NO SIM'. I found this quite strange so I took a nandroid and re-flashed my rom.

Same thing... 'NO SIM'. I tried a whole heap of different combos (kernals, modems, firmwares) but finally had enough, so I went and put the SIM in my bosses phone...Long and behold it worked first time.

This confused me a lot considering it appeared as if my phone couldn't even recognize the SIM.

So, I got back on live chat with Boost and activated the spare blank Telstra SIM, and ported my number to that.

3 hours later, I got 3G signal on my phone...I waited for about 10 minutes before getting all excited, and it stayed! It looked as if it had worked!

My cheers were a bit pre-mature however...About an hour after that I got the 'NO SIM' error again.

I went through the same steps, and was up till late trying to figure it out but I ended up having enough and just going to sleep.

In the morning I got into work and the boss said just try re-flashing stock firmware through ODIN. I had tried this last night so I'm not too sure why this would work, but anyway I tried, and I got signal! :)

After my pre-mature excitement yesterday I wasn't too sure this would stay working..But throughout the day I received calls, texts and browsed the web and it didn't let me down!

I then started driving home...The minute that I got home, I received the dreaded 'NO SIM' error again.

I went through the same steps as before (flashing modems, firmware custom roms etc etc etc) and it still didn't work.

So anyway, I got onto Boost chat and, three hours later they came to the conclusion of sending me a blank SIM...A Telstra blank SIM...

This SIM is now in the mail and should be here mid next week. But if it's anything like my previous two blank SIMS then it won't work.

So..I'd just like to know, has anyone here got any ideas that could help me? The only way out of this that I can see is buying an Optus $2 sim, porting my number to Optus, then buying a Boost $2 SIM and porting my number back..But this will be a little tedious and they may have issues considering the ammount of blank SIMS I have been through.

I'm willing to try any ideas that you guys throw at me, and any input would be muchly appreciated :)

Cheers guys/girls,

PS, I have looked at this thread but it appears that they didn't find a fix other then sending it away: http://xdaforums.com/showthread.php?t=2197422
