Hello. Unfortunately, I have some unpaid bills for my HTC device that I bought from my carrier, and we're bound by contract, so they locked my sim card, and now I can't call and recieve calls. If I root my phone, can I remove this blockade, so that I can use other SIM cards from other carriers? I assume there's some hidden software that allows them to block my phone from networks?
as i understand they block you number not the device.
if you have try other sim cards and they don't work what i can think is that they block the device with the IMEI but this happen after request of client if the phone get stolen.
if they do that to you and block the IMEI dude change country :laugh:
but for sure the block the sim card. so pay the bills to use that number again
It's actually deviced blocked from using any sim cards, and after unpaid bills they blocked the sim card aswell. And as I understand, there's probably some software inside a phone that is not visible, or as you said IMEI is blocked, can that be unblocked by rooting the phone? Yeah, well, I will not pay them bills for now, I'm just trying a way to remove this blockade so I can use another sim card and have network.

thats why i asked you if you have already tried another sim card. if others sim cards works then they block only the sim card, which is more common thing they do. if they block the imei which isnt software is a unick id for this device , then rooting the phone can help to change the imei with imei of another old device you have but this is very tricky if you dont know how to do it.
Yes, I have tried another sim card... and when you buy a phone with a contract through a carrier, it lasts 2 years, and in those 2 years you can't use another sim card, just the one from their network. So, yeah, they blocked IMEI then. Now I just wish I knew how to root the device and change the imei. You know any good guides for it?
edit: There is some online service specially for HTC phones unlock, they said they can remove this blockade with the code they send me. But I'm afraid to not waste money if the code won't remove it. Because they told me they're making official network unlock on HTC server, not on my local server, so official factory permanent unlock.
I don't trust those services. as for root here at xda there are programs to root your phone instead of change rom. as kingroot. also at YouTube are videos how to change imei. I haven't try them. so be carefull when you do that.
I have checked if my IMEI is blacklisted, and it's not, it's clean... so only SIM card of my carrier is locked then. Because when I insert SIM card it says "SIM card is locked", and when I insert SIM card from another carrier it says "Network is locked".
I think is easier to unlock the network. but again I don't know how. never happend to me and I answer you after my research. practical I haven't try any of methods that are around the internet.

Hi
I just bought a Cingular 3125 on Ebay, and according to the seller the phone was SIM Locked.
So I assumed it was Sim Locked and meanwhile I receive the phone I started looking around for different ways to Unlock it, so when I finally received my phone, I inserted my SIM Card and worked fine! so my questions are:
After all of the events, can I say that my phone is SIM Unlocked?
Is it possible that my local Carrier (Telefonica) has the same configuration as Cingular so the SIM Unlock Code was not required?
Thanks for your help and your expertise.
Best Regards
If your SIM worked I'd say it was SIM UNlocked AFAIK no SIM from another carrier will work if it's SIM locked. A simple way to check would be to try another SIM!
If I understand correctly, there are actually different levels of sim locked. Hey may have just been locked out of his own sim which can happen if you try the wrong code a few times. That way another sim might be able to work on that phone. I am not sure since the wireless carriers that I worked for never used Sim cards.
UPDATE
I just checked with my wife who works for ATT and she stated that it is possible for people to lock themselves out of thier SIM cards and not the phone. Should the person lock themselves out of the phone and SIM then they are kind of SOL unless they have great friends like the people at XDA or can get the manufacture to give them the lock code.
Hi, I'm new to the forums and new to unlocking phones. But I wanted to unlock my vibrant, I have my unlock and unfreeze codes but when I put a different sim card in it just tells me to call customer care and gives me no option to put in an unlock code. Can anyone tell me what I'm doing wrong?
Different sim card have to be from different service provider like at&t.
This is first time I hear that unlocking option won't appear after installing different sim card !
I tried using a net 10 trac fone sim card, since I read from other people on here they said it would work. but when i put it in and start the phone i can use my phone but when I go to the call screen it says "sim card crash - Please contact customer service". So Im gonna try an at&t card(with data plan) from my friend hopefully it works. Also I have another question like I said Im new to this stuff. If I still use my tmobile sim card can I still connect to at&t's internet/data?
I would think that to access AT&T's network services, you would need to have the AT&T sim installed in the phone.
You have to put different sim card other than T-Mobile to get unlock code screen !

Dude WOLF, not to be rude but if you read I put a NET 10 TRAC Fone sim in, not a t-mobile.
anyways on a better note. I finally have it unlocked! I put in a friends boost mobile sim, Screen popped up and put the code in. sweet.

Nope...you'd need to put in an AT&T SIM that's tied to an AT&T account with a data plan.
I tried to get my phone unlocked today, however ever since then my phone hasn't been able to connect to any networks. I had to give my Imei number to get in unlocked, is there some way this could have been used to block my phone?

Yes in theory it could. Try the old sim and see if it works.
To block an imei requires access to the network systems, although you could phone them up and perhaps maliciously block an imei.
Did you use a reputable unlocker?
I used one off ebay however they had 15000 positive feedback.
I rang T-mobile and they say my phone is not blacklisted but its also not been unlocked. I dont know if this is true as when I put my unlock code in it said unlock ok and now when I put another network sim in it doesnt ask for the code. Ive since tried to use an orange sim card in it and this works but I dont know if this is anything to do with the fact that Orange and T-mobile have merged.
If it isnt unlocked then i dont know where to put a new unlock code in.

Lol you are fine.
Tmobile don't know it is unlocked. It worked fine if the sim doesn't ask for the code now.
If an orange sim works then phone is OK. What is original problem again?
Lol sorry I havent been very clear.
Ive bought a Tesco mobile sim and that is what I want to use however when I try this sim it wont connect to the network. Ive also tried a O2 sim with the same result however an Orange sim does work
I really have no idea what could be causing it and ringing Tesco/T-mobile has been no help at all lol.
Might be a stupid question but are you sure you can get Tesco Mobile signal? Both Tesco Mobile and o2 use the o2 network. So that's probably worth checking.

Ive tried it in my girlfriends iphone and it works perfectly so I cant imagine its the signal. I'm totally flummoxed, the only thing I can think of is if the phone isnt unlocked, but then why then does the orange sim card work?
OK I've come to the conclusion that it hasn't been unlocked and the reason the Orange sim card works is something to do with their networks being joined. If this is the case is there a way of re-entering the sim unlock code?
TMOBILE has blocked your sim, you may need to root

TMOBILE has blocked your sim, you may need to root. My experience is this: I have a rooted HTC that works fine, however when I put the sim in my S2 or a second T-Mobile phone I get the error message "cannot connect to network" even though I have 5 bars.
hello to everyone i would like do modify my root but i have never done any of this could anyone guide do the safety way and easy one if this matter is from att us

Well, if the phone its locked to AT&T then you call AT&T. There is no way to unlock now though from what I understand unless of course AT&T can for you. This its why you should NEVER just guess at the unlock coffee and instead call the company you bought the phone from or get an unlock code online for less then $20 usually.
To check root install an app that needs root (root explorer works, as does any other asp that says needs root)

I bought a S9+ online from someone on facebook but when i put in my sim card in it would work for like an hour before it my sim get network blocked saysing "sorry, this phone is blocked from your netowork." and the sim card is still blocked when i put it back in my old phone, will rooting my device fix this problem? or how do i fix this problem?
Maybe unregistered imei..
Call the carrier and request support on the issue. If it is the sim card they can fix it.
If it's not the sim card and it's the phone causing it then the phone is probably blacklisted. The carrier can tell you if this is the case. If they do say the phone is blacklisted then you cant fix it, the IMEI is blocked on the network.
