Total newbie question about SIM unlocking Diamond

Hello everyone,
I'm thinking to buy an HTC Diamond over eBay, and have question about SM unlocking in my mind:
- Do I need to have a SIM card, which the device currently locked in, to unlock it or is it possible to execute the unlocking software without a SIM card installed?
They usually sell phones re-branded and locked to a specific network, and not every network operator works in my country. For example, if I buy a phone locked to Orange, it will be impossible for me to unlock it, if I need to run the unlocking software while an Orange SIM is inserted.
Thanks in advance.

Well I'm not completely sure that you need the sim to unlock it, but what I am sure about is that if you buy the HTC Diamond (not the T-mobile version, or whatever other carrier offers it) it will come unlocked. HTC simply makes the phones and if you buy one of their versions it will be unlocked as a standard.
Hopefully I helped answered your question instead of wasting time for both of us

every phone i have had to have unlocked can be done without any sim card in it

Thanks for your replies and sorry for a late response.
I have already bought my phone and waiting for its arrival. It is an Orange branded device, which is unlocked with a software obtained from unlock-htc.com, according to the seller. So, my problem with the SIM unlock seems solved

I think the bigger question is, once you get it unlock can it be used with AT&T or T-mobile 3G frequency.

We don't have those network operators here in Turkey. In fact, we don't have any 3G network operator at all
If we think that people are discussing about 4G technologies like LTE in north America and Europe, we can easily say that cellular network providers are evolving very slow in Turkey I don't think I will have problems with our current old school GSM providers with a SIM unlocked device.
I have to wait and see of course, I will let you know the results.

[Q] Unlocking tmobile usa HD7 a sure thing?

Hey guys I've asked this in some thread before but never got an answer. I live in Canada and was thinking of telling my friend who's in the US right now to get me a contract free HD7 from tmobile so I can unlock it and then use it here. So I just want to know if it's a 100% sure thing that the phone can be unlocked before I buy it since I won't be able to return it in case it can't be unlocked. I don't want to end up with a 500$ paperweight since I've read that some people couldn't unlock theirs.
Because if it's not a sure thing, I guess I'll be getting the optimus 7..
Thanks!

T-Mobile will give the unlock codes after you've been a customer for a certain period of time. The length of that period and what happens to it when you've bought the phone at the unsubsidized price are somewhat variable and honestly I would not rely on this happening if you are not a T-Mobile customer.
However www.htcimeiunlock.com will probably be able to unlock the phone; I personally unlocked an HD7 in 15 minutes with their service. Bring a laptop or something and check the IMEI right in the TMOUS store before completing the purchase -- the site will tell you definitively whether it has the code for your specific device.

Like I said I'm not personally going there. My not-so-tech-savvy friend is so I can't ask him to do that. But do u think that eventually after a certain period of time that ALL htc phones' unlock codes will be available or are some just never unlockable?

It's almost certain that it will be available now. And if not, it will be soon enough. I wouldn't worry about it. Worst case scenario is that you have your not so tech savvy friend call tmobile and get the code for you. It shouldn't even come to that though.

I am having trouble getting my HD7 unlocked. I tried www.htcimeiunlock.com and it does not recognize my IMEI. I'm trying to get it unlocked at a different website and they have to contact HTC directly to get the unlock code.

Hi...
I bought one from T-mobile and he told me after 45 days I can call him to give me the unlock code.... But I couldn't wait and I used this website cellunlocker.net to unlock my device and it's working without any problem....Thanks!!!

I also ordered an unlock from Cellunlock.net last week.. Still waiting on a code for my HD7. Apparently HTC is way behind on providing codes to the unlockers for newer batches of phones. Getting annoyed either way, I have this HD7 in Toronto that I can't use.

It's a sure thing as I am using a T-Mobile HTC HD7 on FIDO, so the phone is unlocked. I'll sell you mine if you are in Toronto. T-Mobile phones are different band so you can only get Edge data through it. Kind of sucks if you are use to 3G speed. If you are going to use the phone on Wind then it's same band and you will get high speed data. Anyway it is possible to unlock - I've been using the phone on FIDO for almost 3 weeks now.

I have used www.cellunlocker.net to successfully unlock two of my HD7's. Codes came via email within 30 mins, both times.

[Q] Unlocking Droid 4 for International

I have a friend who's interested in buying my Droid 4. And he wanted me to unlock it for him, so I was looking around... pretty much everything out there looks like a scam (either it wants me to install software, and makes me take a survey to get a password, or they want $28 for a code, etc)
He lives in Italy, uses the Wind network, which he says uses 4G LTE. I've seen on other posts that it doesn't need to be unlocked to be used internationally... is that correct? Or would I have to do something in order for him to use it?
Right now I've got my Verizon SIM card in there, obviously I would remove that before selling it to him. Can it be used with the stock ROM and still work internationally?

Should be no problem. I have used my D4 in Germany. Just popped in a local SIM, got a text which provided the necessary changes for APNs, and was good to surf and call away. My Droid is stock rooted, but I don't think you need to have root.

So basically, any of those sites claiming to help you "unlock" the Droid 4 are scams?

Well, don't know what they claim to do. But you only need to unlock if you want to use a different provider within the US. Verizon locks you to their network within the US. Outside you can have any provider you like.

They claim to give you an "unlock code"... which as far as I know doesn't even exist or it would be common knowledge by now.
But that's nice to know, I've never traveled abroad with a cellphone (I didn't even own a phone back in 2006 when I went to England) so I thought "unlocking" a phone was a universal thing to remove carrier restrictions.

No unlock required
I just got back from Ireland. Per Verizon's instructions, I had originally called the International Customer Support number to have it unlocked for European GSM usage. Customer support informed me at the time, that the phone is unlocked for international GSM from the factory. Once I arrived, I just swapped out the Verizon SIM card for a local one. It took a little configuration to get the APN/MMS settings correct, but the local phone rep was able to fix all those basic settings.
Good Luck. I'm sure everything will go smoothly for you.

[UNLOCK] What to do now?

Hi everyone,
i got a Sprint HTC One M8 from ebay, it is new but i was planning to use it on AT&T network, since it have a Sim Card Slot. Furthermore, even though i'm living on the US now, i'm from Brazil and i was planning to use the phone there as well.
And now starts the problem.
I called the previous owner, asked him to contact sprint to make the sim unlock procedure. He did so, providing me the MSL for the phone. The next step, he said, was to "flash" the phone on AT&T in order to get it connected to their network. I tried several sims, even bought a new one and activated it but with no success.
I spend almost 2 hours on the phone with the sprint's international support, and all they said was that they did everything that they could about unlocking my phone and now i should contact AT&T.
I'm afraid of staying on this infinite loop and i want your opinion.
Does anyone in fact unlocked their SPRINT phone to use on another GSM US carrier? If yes, what did you do? Because i'm planning to return the phone and ask for my money back.
BUT, with the "International Unlock" i should be able to use the phone on ANY international carrier? Because if that is the case, maybe i keep the phone to use when i go back to Brazil.
Thank you very much!

On the CDMA version of the M8, it lacks the LTE bands needed for Domestic carriers. You can use it overseas somewhat, but not too well. If I was you, I'd grab a Droid Turbo for ~$200-$250 off eBay. It just recently got its bootloader unlocked finally

Network unlock?

Hi all. My friend got a new P20 Pro, which he though was network unlocked but it isn't. Is it possible to unlock? Do the many unlock sites work with this phone? Any recommendations if so? Thanks!

I am also looking for a solution as I am due to travel to asia next month. Mine is locked to EE. I can carry two phones but I really wanna avoid this for safety reasons and also because when holidaying i'm always carrying other valuables like passports, cash, external battery bank, sunglasses etc etc.

A network lock does not mean it cannot be used in another country, you can still travel else where and use the phone with locked network, well it's actually called SIM Lock not network lock, when SIM is locked it means it only accepts 1 provider to be used on the phone. But when you travel it can still borrow other networks systems so you will still be able to call and send sms and such as you can do now.
So let's say you live in UK and got provider called three and it's locked to three, then when you travel to asia it will automaticly borrow one of their network somehow but it will etc say three (vodafone) on the phone, that means it is borrowing network through vodafone in asia but billing will go via three and not vodafone. since vodafone will bill three and then three will bill you for the sms, calls and such.
Answer to OP: easiest way is to go to provider where your bought the phone from and have them unlocking your SIM lock on the phone. But it would cost you money for it thought. But be aware, if your phone is under a subscription deal then provider will reject the SIM unlock. Since they don't want you to try use another provider or try cancel current one while you got phone from them cheaper under a subscription. So this is why SIM lock is set on the phone to avoid this. But you can still use other networks called roaming with same SIM card, like i explained further up how it will go when you travel.

Thanks for the reply, Jake. I was hoping to use a local sim on my holiday in Asia and then to Egypt... as data is a LOT cheaper using a local sim instead of roaming on my UK EE sim. If it is network locked, it would mean I cannot use a local sim abroad, correct?

never heard of something called network locked, but i have heard of sim lock. sim lock is diffirent to network lock, it means you can only use carrier you got phone off. But it will still use function called roaming what so ever when you travel to be able to connect to your carrier through other carriers systems.
So try asking your provider again is it network lock or sim lock. They could of meant sim lock and not network lock. If they say this then you are good to go and can use your SIM card anywhere, but then it will show on phone something like Three (Other operators name) since it will automaticly borrow through another carriers system. But you will be charged via your local carrier for the calls, internet use and so on.

So as stated, mine was locked to EE and they wouldn't unlock it.
I used https://www.unlockunit.com and got some unlock codes in less than 24hrs. My o2 card now works!
I assume now it's sim unlocked, that any card from any country would work. But that's a guess on my part.

This is very exciting! Your EE locked P20 Pro got unlocked using a code from that website? Now you can use an o2 sim in it?
Please confirm.

Yup! That's what happened. Basically, a friend purchased the P20 from a third party site (ie, not EE) with the intent to sell it (to me in the end). He assumed it was unlocked, which it wasn't on arrival. EE wouldn't unlock it until 6 months in.
I put the details into that site and honestly expected nothing. Less than 24hrs later I got a bunch of unlock codes, first one worked. Very happy

they even don't have mate 20 pro on list just mate 20 lite.
So it's impossible to take out simlock with this fake site

Network / SIM lock, same thing.
Basically you just want to use another SIM than was originally intended, for travelling purposes or for if the phones sold and the buyer wants to use another SIM.
There are a tonne of services on the high street and online, eBay etc who can do this.
Should be quite cheap.
EE will provide it for £20 so long as the phones over 6 months old. Least that's what it used to be.
They can do it for free but you'd have to sweet talk them.
It's your right to have it unlocked, mobile networks shouldn't be able to lock them down, certain shops like carphone warehouse offer unlocked phones so I'd recommend buying from them in the future.
OEM's also offer the device unlocked.
