Use a non-AT&T SIM card without an unlock code

I just activated a non AT&T SIM card on my Xperia Ion without using an sim unlock code. just entered all the information for the new Network, rebooted my phone and then selected that network, and there it was, phone service, unlimited data, everything.

Was it net10? Straight talk? Red pocket? Jolt? Or.h20 wireless?

I heard they made 1 and only one magically unlocked Ion. He must've gotten it! Check the box for the golden ticket charlie!

Wish I had the golden ticket. Never heard of it before.

[Q] Can I use any Microsim card to unlock this device?

Hello,
I have a locked T-999 and I'm getting my hands on an unlock code. Can I buy any cheap microsim card to unlock my device or does it have to be AT&T?

I would think it'd need to be a tmobile sim, but I'm really not sure about that.

Insert any non T-Mobile micro SIM. You have to have a SIM that's not T-Mobile. T-Mobile s3 doesn't have access to unlock menu until another SIM is in the phone. At least it wasn't possible when I unlocked mine months ago

Thanks for the responses!
So I can just get this one (http://www.ebay.com/itm/NET10-MICRO...130794368103?pt=SIM_Cards&hash=item1e73f3ac67) and it is guaranteed to bring up the unlock menu?

or just go in to ATT and ask them to use one for a sec. Im sure if you tell them you need to unlock the phone to their network they will have no problem letting you use one for 30 sec.

How to tell if handset is sim free or not?

Hi
Just bought a Note II, I was told it was a sim free model, and whilst its accepted my tesco sim card without issue when I log into google play on my pc its brought it up as an O2 Samsung GT-N7100 so the question is have I been sold a O2 handset thats been unlocked? I know it doesnt really matter that much but curious more than anything

Or is it possible tgey have flashed it with a o2 firmware my mistake?

You could try. Borrowing a friends sim and see if you can send a message. If yes, the you are likely sim unlocked.

The N7100 is the international version so it should be sim free.
To test your if your phone is unlocked, insert another sim card other than your "tesco". And if it shows enter sim unlock code, it is locked, otherwise it is unlocked.

Tesco runs on the O2 network. That is why, sometimes Tesco handsets will work with O2 Sim Cards only etc...

Yeah I know, hence why im looking to change o2 data coverage is shocking and I cant use sky go or tvcatchup using 3g as it comes up with some rubbish about saying im abroad...

About Sim Card's

Sorry for being a noob, but this is my first GSM phone.
Do i have to activate the service first before my phone picks up that i have a sim card in? (Simple Mobile)
Because as of now, my phone keeps saying "no sim card" in the notification bar.
I used this guide to unlock my phone: http://forum.xda-developers.com/showpost.php?p=34661189&postcount=1
Thanks.

The service has to be activated before you put the sim in. Else it will my never be able to latch on to a network

s4 wont read simple mobile sim card

Im trying to get my simple mobile sim card to work on the T-mobile galaxy s4, i bought the phone straight out of wal-mart. The phone says no sim insert sim card. help would be much appreciated

Make sure you push it all the way in and also make sure your sim card is activated, is not defective, and it might be that the phone isn't for tmobiles network? It sounds dumb but some phones when they're not part of their carrier it says that.. And that's all I kno...

Simple Mobile is supposed to be on T-Mobile's network.
