sim card unlock does not work, help!

[zhu_dawg]

i recently bought a gevey 3g sim card. my iphone is 2.2.1 firmware, 2.30 baseband. I insereted the gevey card with my sim and then i put it in my iphone and the invalid sim just flashed on my screen for like 1 second. then i went to settings and i can't see the carrier option below wi-fi. help please!

Not every sim-adaptor works for every FW and baseband, you need to check and see you got the right adaptor.

[zhu_dawg]

i bought it and it was suppose to work with firmware 2.2.1 and baseband 2.30, and that's what i have on my iphone

i really want to know why my iphone flashes "invalid sim" for 1 second then closes without me pressing ok.

also when i go to settings, i cannot find the "carrier" button

[cpjr]

What "carrier button" are you referring too??

[zhu_dawg]

when you go to settings, and you see airplane mode, wi-fi, and fetch new data. I'm refering to the carrier option that's located with these options

[cpjr]

I have no carrier option listed on mine, so im not sure what your talking about.

Gevey-3G - VIDEO

if you watch that video you see "invalid sim" message pop up and you have to press ok. Mine just pops up for a second and disappears.

Also, when they go to settings, they see "carrier" next to the wi fi option, where as i don't have that, and when i pop my gevey adapter and my sim card, i get the 1 second invalid sim message and i where the signal is i see 0 bars

I don't have the carrier option on mine either.
I would suspect your gevey card is either bad/defective or not compatible with your fw.

[zhu_dawg]

i see, then does anyone know why my gevey isn't working, and can someone suggest some sim adapters that work?

Mine works beautifully. First thing.

Power you phone off. Take the SIM chips out. Make sure you've got them laid right in the tray. Pop them back in. Power it back on.

report back for further diags.

/end trans.

[zhu_dawg]

yeah i tried that and i still get the message "invalid sim" and i get zero bars

[myke55]

anyone figure out a good sim card that works for the 2.30?

[blkcadi]

I bought one off ebay for a couple bucks and it works great, no problems, no dropped calls, interwebz work better than my 2G without a sim adapter.
And yes I have 2.30 too
This is the one I bought.

Have use a RebelSim on 2.2.1 with 2.30.03 and worked just like it should.

But sure, no matter which one you get, I'm pretty sure you will find problems here and there, but that's just the risk you take.

About the Carrier button that zhu_dawg was talking about.

I know what you mean and when there is no signal it would disappear, then come back once in signal, this is why you would not be seeing it, because it has not been connected to any Carrier.

For other people who still don't know where to find this or just didn't not understand from what zhu_dawg said, The Carrier Tab/Button is located under Settings > Carrier, That's it.
