Hello everyone,
I'm trying to find out how to SIM unlock my G1 without having an AT&T sim card. I have an unregistered T-Mobile sim card available if it could be used at all.
I tried searching but I must be using the wrong search terms because I keep getting results about unlocking using an AT&T sim card to get the request for unlock code to show up.
I have the unlock code, just need to be able to enter it.
dunno if its the same as the UK but I unlocked mine the other day from T-Mobile with an unlock code and all i had to do was to put the wrong sim card in there (i.e. the one u want to use) and then it should prompt you for an unlock code....
Yup, just shove in the ATT SIM card and it will ask for your code...
I just purchased a unlocked my touch 3g ( I believe Magic) no slide.
At times my phone asks me to do a update.
When I look at what the update is it shows "Android System Update 1.2...The system is required to install Android version 2.2.1 on your device."
My phone states my firmware version is 1.6
So my questions are:
Do I need to perform this update?
Will this update lock my phone again ?
This is my 1st android phone and truthfully I'm not real technical. I have been going around googling different thing to make mysel more familar with the phone and Android.
Any help woul sure be appreciated.
Thanks in advance
Ok so 81 views and nobody knows.
Anybody have any idea what other sites out there may deal with this type of thing that they may be able to direct me to?
Thanks
Could you please provide the info on your fastboot? You can get to fastboot by turning the phone off, then turning it on while holding down the volume down button.

I hope this helps and what you were asking for
Thanks
First off, you do not need to update if you don't want to. Second, I think the update will relock the phone, so I recommend not updating at all, unless you have a reliable method of unlocking again.

I appreciate the info
Ok there are two things:
1) Sim Lock.. if your phone is sim unlocked it will remain sim unlocked.. actually I don't think there is any documented way to re-sim lock the phone.
2) Root.. if your phone is rooted i recommend installing a rooted version of the upgrade if you desire to upgrade.. otherwise the upgrade will either unroot the phone or fail because the phone is currently rooted (possibly causing it not to boot into android until you restore a good firmware)
Remember the sim lock is different from root.. and you can be rooted but sim-locked... or sim-unlocked but not rooted.. the simlock is just the tie in to the carrier and part of the Radio.. not part of the android firmware. Further its in a special radio settings region that is not flashed when you change the phone's radio.
So if you have the stock un-rooted/un-modified firmware and wish to update feel free.. just note you may want to back up what you can first.. some people have had problems with the update going slow until they factory reset after the update..
ezterry,
Thanks for the info.
Truthfully I'm unsure about many things on this phone.
I purchased this phone off Ebay as a unlocked only phone.
When I received the phone I just popped in my sim-set up the phone and was done.
At this point though I'm not even sure its unlocked because it is a T=Mobile phone and my service is myfamily mobile,which is just T-Mobile sold at Walmart.
I put in a sim card from my neighbors AT &T and it asked me for a pin #.
I skipped putting in a pin and the phone opened up but said no service. With that I am just assuming it is truly unlocked.
Am I correct?
Um.. if it asked for an unlock code its locked.. if it was sold unlocked and showing the code you ought to have been provided the code by the seller.
Pin usually just means the owner of the sim locked put a pin on the sim to prevent it from its data/service being accessed by others. (The sims owner ought to know the pin) This pin needs to be entered into any phone the sim is put in.
As soon as I find another person with a different sim card I am going to try it again.
I do think it was a pin # that was asked.
Unfortunately the owner did not provide any sort of code when I purchased.
Its my understanding,and I may be wrong,that you can purchase unlocked phones new,and if so I'm not sure weather or not codes are provided for new phones.
This is all very new to me so I am not sure.

If a HTC Dream/Sapphire was sim locked at the factory you must put in a sim card from another carrier and unlock the phone.. If it was never locked (such as the Google versions of the phones) this is not needed.
Once Sim Unlocked it will remain so regardless.
Yes, this is a My touch 3g google version phone

MT3G = T-Mobile = locked to T-Mobile US but running the Google firmware
ION = Google Development Phone = factory sim unlocked

So does this mean the phone is not unlocked and can only be used on T-Mobile?
or
Is it possible someone paid a 3rd party for a code to un-lock it?
I guess I really need to try like a AAT & T sim and see if I could service,as that was my undrstanding. I was under the impression that any gsm service provider uising a sim card would be operable.
You have gone in a circle now.. I told you if its sim locked when you put in a sim of a diffrent provider it will ask for an unlock code.. once sim unlocked it will *never* be locked again.
You will of course need a non tmo-us sim to be sure.
All I know is the MT3G will have been shipped from the factory locked.. I will not know the current state since the seller prob made sure it was unlocked if it wasn't already so if the phone was sold unlocked ..
The only other way I know to test is harder to do and possible risky with the firmware changes to do it w/o special htc serial wires.
And FYI a pin protected sim will ask for the sims pin before the sims carrier can be read (thus you need to provide the sims pin before it will ask for the unlock code if the phone is sim locked)
Ok,gotcha.
Sorry,told you not to savy
So I'll test another sim again and see what happens.
Thanks again for all the support

Ok.
So I pulled the sim card from my neighbors AT &T phone and when the phone booted up it asked me for :
"sim network unlock pin"
unlock
dismiss
My neighbor told me he didn't have a sim pin,but he used the code he has to lock his phone.
I received the same message when I tried someone elses sim who also states they have no pin number.
Message being: "Network Unlock Request Un succussful"
So am I correct in my thinking that this phone is not unlocked? and or it is sim locked?
I just e-mailed the seller asking him if he had the unlock code for the phone,so I can now only wait for his response. In the past he was not very responsive to past e-mails
I have a Samsung SGH-i437 that was a contract phone from AT&T. I wanted to unlock it for use over seas, so I rooted the phone and installed CyanogenMod cm-10.2-20130925-UNOFFICIAL-expressatt but the phone still has a carrier lock on it. I now have a unlock code but can not get the prompt by using #7465625*638*CODE# because it give me a no network message. When I insert a different sim it does not recognize it. It only has the icon for the sim with a ? make on it.
Any help would be appreciated!
4 days and no help!

Hi.
I bought a locked s8+ from Telcel México. I want it to use it on Att, I have the unlock aim code. The problem is when I instert the att sim I got a message "SIM network PIN blocked. Enter Sim network PUK." and a small lock blue icon. But I can't write anything, there is no keyboard option or anything. Any help? Thanks!
Have you tried another SIM card? Maybe read this: https://www.att.com/esupport/article.html#!/wireless/KM1000485

I just unlocked my phone this weekend. A number pad should have appeared. If you didn't turn off the phone to change the SIM try restarting. If that doesn't work try a different card.

Tried 2 different cards and had the same screen.
Now I flashed a new rom, that screen disappeared but now when I insert a new sim car got a new screen and now I can write the numbers. The problem is that I don't have the PUK code, I think that I need an unfreeze code, anyone knows how can i get that code? Or how can i unlock my phone?
Thank you!
Same **** with mine.

I got S8+ from f#c!¢n Telcel and paid for the Network Unlock code and have the same screen with the blue icon and cant do **** about it. With the new ROM ( Which one did you flash ) did you have any luck, have you unlocked your phone ?

You need the PUK code for the new sim card - most print this on the card that you popped the sim out of. If you don't have the original outer card, then call the carrier for the NEW sim card you are trying to use and they should be able to help you.
I have a ATT 930A that I successfully flashed with 930U and it works great. I was thinking of making sure it was SIM unlocked in case later I wanted to sell it, so I made a request of ATT for the unlock code but when I try it it tells me the unlock was unsuccessful. Do I need to go back to 930A to make the code work?
Probably yes
I don't think so. Just put in a non AT&T SIM and it's gonna ask for an unlock code

I did but the code att gave me didn't work.
So did the phone prompt for a SIM unlock code and you typed it in, got an error? What is the error? SIM lock should not change when you flash different ROMs yo the phone.

Yes, after entering the code it says "incorrect network unlock code entered"
I had this problem with my S7. I had paid off my contract however every time I tried input my IMEI number to the AT&T unlock device website it would tell my my IMEI is invalid. i contacted AT&T customer service directly and gave them my informatio. They had to put the case in for the unlock code themselves. Reason was since i didn't finish the 2 years even though i paid off my contract it got lost in the system hope this helps
