How to check if phone is "unlocked" - General Questions and Answers

I have a HTC Touch Diamond that I am trying to sell on Ebay.
Its a asia-pacific set and I realised that if I want to sell it on ebay it should be unlocked so that it can be used with other telcos.
How do I know if my phone is unlocked? Its already running a custom ROM.

Do you have a Sim-Card from another provider?
Than you can insert it in your phone and try to call someone with it!

So what you mean is as long as another carrier's sim card works on it its "unlocked?"
Also how do you check if your device is cdma or gsm?

So are all verizon Rhodium phones CDMA with GSM only when out of country?
Which meaning at the moment have no HARD-spl and are able to flash?
I've added some custom apps to my phone which is from verizon and is not flashed. So i was just curious.
Thanks,
Alfredo

If you call Verizon (and have their service for awhile, in good standing) they will guide you to unlocking the SIM slot 'for use outside of the country'. Once unlocked, it will work with TMobile, AT&T and any other GSM provider in the US that doesn't do IMEI checking, or that allow the TP2 on their network, in which IMEI checking wouldn't be a problem.
Anyways, get the unlock code for your device (specific to your device) from Verizon, scroll to SETTINGS on the homescreen, click ALL SETTINGS, click PERSONAL, click SECURITY and enter the unlock code they gave you and your phone will SIM unlock itself.
As for Hard-SPL, I haven't seen anything about it yet.. but I haven't been searching, since the phone already does what I'd like it to with simple cab installs.
I hope this helps!

Yeah ive had verizon for a good amount of years now. So i might give that a try. and yeah. I agree about hard SPL.
Are there any other advantages to unlocking the sim card other then being able to change services?
I am still new with all this, and unaware the advantages of unlocking the SIM card.
Curious for In Country and Out of country.
Like what are benefits of it while still in the states?
and what are the benefits if i go to canada? does this mean i don't have to pay extra for the plan while in canada to make phonecalls/texts/data?

I believe you may be incorrect on that, check this out, I have yet to verify this my self but from what I have read here and other places the GSM will be unlocked for use overseas. This way you can use another country's SIM card instead of Verizon's SIM (expensive rates) while overseas for an extended period of time.
There are now several threads in several forums about this.
What people often leave out when they talk about what their phone can do is what carrier they have it on.
With Verizon, when you SIM Unlock the phone you can toss in any SIM and it'll work. I personally have a UK SIM and works fine in the US on my Verizon TP2 unlocked. Others have reported using TMobile (US) or AT&T (US) SIM's just fine in their Verizon TP2's after unlocking.
Sprint TP2's come unlocked but will NOT register at all on US carriers (even with a foreign SIM).

Oh so i have to somehow get a hold of another sim card?
nowwww i get it.
so unless i plan on actually going out of country there really is no point in unlocking my phone.

I unlocked mine, just in case I ever decide to leave Verizon to go to Tmobile or AT&T (yeah, right lol).. or for when I upgrade, it makes it more universal when it comes time to sell it.
It costs you nothing if you're a Verizon customer in good standing, I'd unlock it just in case
-mak
Yeah good point. I was more curious on flashing purposes, but TBH i have no use to flash it. Though once the markeplace comes out, im assuming its going to be like the iphones appstore? and hoping in time we find ways to "jailbreak" or something to get them free, thats always fun lol.
Now i do travel to canada a lot. But unlocking it has no use unless i actually pay for the plan and a sim card? I know verizon offers a plan for it, but i dont got that much to where il pay extra for the plan was just curious.

some folks over at PPCGeeks pointed out that in some situations, it might be cheaper to just buy a prepaid sim card when traveling abroad, as the prepaid cards could prove to be a cheaper alternative to verizon's international roaming rates through verizon's sim card, included with the Rhodium.
Alright, thanks i'll look into that.
the problem with going to canada is the sim card has nothing to do with their network. it is still CDMA in canada and while you may have an unlocked phone and different sim card, verizons network will still pick up your phone and charge you accordingly.

If you have an unlocked phone and a different SIM card in, if you set it to GSM mode Verizon won't/can't charge you for using it in Canada.
Hope thatyour right iamrobk, elsewise im confused.

[Q] how unlock my Trophy(VERIZON)?

Hello everyone:
I am a chinese,I bought a Trophy(Verizon) from Ebay,but it is locking,and I can not use the GSM function.
The I contact sellers on Ebay who can unlock the HTC phone,but they said my phone's IMEI can not be found from htc unlock code's datebase ,so they can't find the unlock code.
It mean the IMEI was Not Found On Database or it is Not Available.
Have any methods can unlock my phone's GSM network?
I hope someone can give me a help.
Best regards.
TKS.
Does the phone not have the option to toggle to GSM mode, or does it just not work? It should be under Settings -> Cellular.
I don't think the Verizon Trophy is even SIM-locked in the first place. At least, not in the usual sense. However, I have heard a rumor that they block it from being used on the USA GSM carriers, T-Mobile (US) and AT&T.
If you're able to take it to a Verizon store, they can probably remove any unlocks on the device. They may or may not be willing to do so for free, but they probably *can*.
Out of curiosity, why in the world buy a predominantly CDMA phone (even if it has a GSM mode in addition) if you're a GSM user? There are plenty of GSM Windows Phones, most of which are arguably better designs too. Verizon users around here hate that the Trophy is the only phone available to them, and I truly sympathize.
when I select the GSM model and put in a SIM card of CMCC,It display:
This SIM card can only be used on specific networks.Contact your customer service center for the unlock code.
So it's should be a GSM network lock.
You only have 2 options first you need to find the way to bring it back to Verizon to unlock the phone but if you're in China right now that probably impossible.
Now the second option is to buy the unlock code on eBay. I have no idea why you phone couldn't unlock did you ask the right seller? Because HTC Trophy actually have 2 version one is European and the other one is US (CDMA and GSM) You may need to try other sellers if you can find them.
I have HTC Trophy Verizon and my brother also has one he went back home and unlock the phone before left US and it works fine with GSM/UMT.

How to tell if it is SIM locked or not..?

Is there a way to tell if the htc one s is SIM locked or not..?
I've got the one s which has O2 CID and runs O2 version of JB on it but I don't think the phone is actually sim locked as o2 dont tend to sim lock their phones, is there a way to tell without getting hold of a different carrier sim..?
Thanks

Put another SIM Card in it. If you're referring to O2 - UK then I assure you that the phone will be locked. Unless you buy it from phones4u, carphone warehouse or fonehouse, the phone will ALWAYS be simlocked. It's the networks way of making sure your custom stays with them, becuase they know that most people can't be arsed to go through the hassle of unlocking your phone. If you're planning on rooting, you can SIM unlock your phone for free, and there is absolutely zero risk of you breaking the phone because you're not re-writing any files, you just need SuperUser access to read them.

Verizon HTC ONE M8 to work in Canada?

Hello all, I have an HTC One M8 that I bought while working in the US for a year. I am back in Canada and want to use it with Rogers or Bell doesn't matter who. I thought it was unlocked so I could use with anything but apparently I was miss-guided.
When I put in a Rogers SIM card it says SIM from Unknown Source or something along those lines. When I go into about in settings I can see that it picks up the signal for rogers and also shows my cell phone number. I'm guessing there is some sort of way I can make this thing work here?
Can I overwrite the ROM and put a Rogers ROM in? I have no clue. This is about as far as I get with phone tech.
Any help would be greatly appreciated.
Hi!
Verizon M8 is sold "internationally unlocked", so Verizon customers can use it everywhere in the world: not just the CDMA networks (Verizon's) but also in GSM networks (most widely spread standard). I live in Spain and mine works in a GSM/LTE network perfectly and it does too in France, Germany or Italy.
For your mobile to work in Canada, you have to make sure your phone is sim unlocked. If you purchased it to verizon you can ask them to remotely unlock it, as you've paid for it, and they will. They may take some time, but they will. Once it is sim unlocked, you will be able to use it with any other operator's sim.
Note that, even when it is sim unlocked (and functional), you may be receiving a notification of "unknown sim" when the phone starts and an icon in the tray. It's just a software issue, as it will work, but to make it dissapear you have to do much more complicated things (unlock the bootloader, get root privileges) and i'm not sure it is worth if you're not familiarized with these sort of things.

Unlocked note 8 AT&T but no gsm sim works

Hi everyone
I’m kinda puzzled with this note 8 and need some advice. Recently got a note 8 from AT&T and since I was traveling I had it unlocked to use by a third party company ( since att doesn’t unlock until Device payment is complete)
I got the code, unlocked the phone successfully. Before I left USA I put a working T-Mobile sim to test if connectivity, no luck, it doesn’t work, I tried a Verizon sim, nothing works....
Note... this T-Mobile sim and Verizon sim if I put it on a different device it will work...
any reason why this is happening

The phone is not unlocked. Seems like an error happened when you got the unlock code. I'd try again.
Did you use this device on the att network? I mean, do you have it activated?
If you unlocked it by codes and the message after inserting the code is something like "unlock successfull" then your device must accept other GSM SIM cards.
Also, I would recommend you place a 5 min call with your device, with the att sim card and then insert again the tmob card.
What is the message when you insert the tmobile card in this device?
I did the same thing by using a Tmobile SIM during the unlocking process, and it worked on TMobile right after I unlocked it. It sounded like you did not unlock it using a different network SIM but using some other method. I am not sure if that mattered or not.
I then traveled to Asia, and I bought and used a local SIM card with zero issues. The 4G LTE was faster in that country than AT&T... LOL
