Hi guys,
This is my very first post so please be patient with me.
I just received my HTC TD purchased through Ebay. It is a model P3720 with the Telstra NextG branding on box and phone cover. It was advertised as unlocked yet it does not read my 3 sim card. It comes up as sim card missing.
How do I resolve this issue? Can someone help? Im excited about receiving this phone today and simply dying to play with it, so if any of you can give me some advice I would greatly appreciate it.
Thanks
Step by Step...
I'd say first get a Telstra SIM and try that in the phone, this will tell you if the phone is working correctly... Then get a SIM from another network (not 3) and try it with that SIM, if the phone recognises the SIM it is unlocked, if not it isn't and you can get it unlocked by looking at the sticky Diamond unlocking thread on this forum...
If it works with the second SIM but does not work with the 3 SIM take the 3 SIM out wipe it off blow onto the contacts in the phone and try it again, if it still does not work try the 3 SIM in a 3 branded phone to see if it works. If it does and the Diamond is unlocked you might have to phone 3 customer services for advice - don't expect much though as they will probably say they don't support phones which are not branded as 3 phones.
The alternative is to search around here for some more help.
Hope the above has been helpful.

My Desire came from vodafone on contract, it was officially branded. It didn't come with vodafone software or anything but did originally need a gold card to root it.
I have rooted, installed custom recovery and ROM, gone S-OFF.
Is my phone sim locked to vodafone? I have put an old T-Mobile sim card in and it booted, no errors, in status it does show the phone number associated with the T-Mobile sim and am showing signal. If I try to make a call I get 'mobile network not available'. I'm sure there is no credit left on that sim, so that might explain that.
Anyway to know for sure, I am going to be in the states for almost two months and want to take it with me and get a payg sim card there.
Thanks!
Vodafone don't tend to SIM lock their phones anymore, try another SIM that you know is working (but if you have no credit you should still be able to receive calls)
Im pretty sure vodaphone network locks their devices, in order to unlock your device and be able to put other network sim cards in the phone and be able to use them you have to request a sim-unlock code from vodaphone or buy one online. Im currently in a similar position where I actually have a code but cant use it, most probable because I have a custom rom installed. When you enter your non-vodaphone sim does it not ask for a sim-unlock code?
Edit: I guess im wrong about vodaphone's policy then! Ignore all of the above!

Thanks,
Well, was not able to receive calls but then again that sim card has not been used in 2-3 years so it is possibly not 'network aware' anymore. I'll see if I can pick up a current sim card somewhere to test.
Either way I guess worst case scenario is paying to get it unlocked in the States, so no big deal.
Thanks for the help guys.
I'm really not sure this is the correct place to put this question (Mods, please move it if needed) .... as it sort of needs to be where both the UK SG-SIII users as well as T-Mobile SG-SIII users will both see it.
I contacted T-Mobile C'S and got them to email me an Unlock Code so that I could use my phone while in UK visiting my Mum for 2weeks, but when the email came the very first part of the instructions says "you must perform this unlock function with a NON T-Mobile SIM card installed"
Hmmm well since I am still in Florida, I can't do anything ahead of time but I wanted to try and research / find out what my options were when I get over there (flying into Manchester) ahead of time so that I know what I am going to do when I land.
Anyone out there with experience at international travel, multiple SIMs, pay-as-you-go plans etc?
Any help would be much appreciated. Thanks
It's easy to get it unlocked ... just use one of your friends ATT sim cards from their iPhone because s3 requires micro sim. Pop it in turn it on, it will ask for the code, put it in and your good to go. Then just put your sim card back in and your phone is unlocked for any gsm. When you get over seas find a service that has sim cards pop the sim in and your ready to go.

Hey everyone. So I'm in Germany for the next 10 days for work and when I stepped off the plane I tried turning on my phone and it's not getting any signal (I spoke with Verizon and had them enable the international coverage using the sim card number and all). I go into the menu settings and manually select global and it's telling me there isn't a sim card installed but there is. Could it be the ROM I'm using, or do I have a bad sim card? Please help, I can't go 10 days without a phone, I'll be screwed.
Thanks in advance.
Wow, I feel like an idiot...they really shouldn't let you install a sim card backwards....
The wife put it back together after she pulled it to get the number off it and I never thought to check if it was in the right way...
Hahaha. That's great. Glad it all worked out
Hi there,
I am a so far satisfied owner of a G3 but since 10 days I have been having an issue with my G3 and I wanted to ask around if someone here has an idea or some thought that could help.
My situation is the following:
About 2 weeks ago I switched my mobile service provider. When my new SIM card from my new provider arrived I tried the SIM card in my G3 but there was just the massage "no sim card found" and no possibility to type in your PIN. So I thought maybe I got a defective SIM card, it happens. I ordered a new one but the problem remained with the new card in my G3 aswell, still no pssibility to type in my PIN. So I tried troubleshooting and started trying the SIM cards in diffrent phones. In other phones the SIM card from the new provider worked perfectly and I was able to type in my PIN like it should be. When I tried putting other SIM cards in my G3 (from my Mom, Dad etc. and also from different providers) none of them worked in my G3. Even my sisters SIM card from the same new provider AND she has also a G3. So far it seems that the my G3s SIM card reader is broken.
The weird thing is that when I put in my G3 my old SIM card from the old provider the prompt to type in my PIN appears as normal as ever. If I type in my PIN the phone accepts the PIN normally. There is just no reception which is normal because I am not with my old provider anymore. I also have to add that the phone appears not to have SIM lock. I bought it from a private seller but he bought the G3 with a vodafone contract and I was with O2 at that time and the phone worked perfectly. Just until I switched from O2 to Congstar (Telekom) the problem began.
So I thought I just send it back to LG because I still have warranty on the device. The phone is rooted so I need to admit that it was not that clever to send the phone in without rolling back the rooting. Today I got a letter from the repair service from LG with an estimate of cost which means no surprise, no warranty for me. You guess right, the reason is the rooting they write they need to change the whole mainboard. For me this sound like plain bull**** because on the document they send it seems like the first thing they check is a rooting and if the device is rooted then thats the cause. But ok it was pretty stupid from me not to unroot it, I know.
Now I wanted to ask you if someone had a similar problem with their G3 or has an idea what the cause could be. Like mentioned above with my old SIM card the phone worked normally. Just the new cards and all other cards, even another O2 card did not work. Is it possible that just one and only one SIM cards gets accepted from the phone?
Sorry for the long post. I am thankful for any advice.
Best regards,
Patrick
I'll have my phone back tomorrow. If someone still has an idea I would be very thankful about some thoughts or suggestions.
Thanks!

It seems your phone is Sim locked.
You need to find the unlocking code that you need to put in the hidden menu.
Google for LG G3 Sim unlock.

Hi,
thanks for your reply! Iam not sure it is because of sim lock- Because the phone came with a vodafone contract but when I bought it I was with O2. And with my old sim card from O2 the phone worked perfectly. Weird is that when I put in a different O2 sim card the pin prompt also did not appear. Same with any other sim card ...
Thanks,
Patrick
Or did maybe someone have a similar experience with a different phone?

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!
You can buy an unlock code for 3.5-4€ , works for any LG G3 variant
Try it
Ok, thanks! I will try it!
So I just looked at what I have to do and tried the combination 2945#*855# to see where I have to type in the code. The thing is when I choose any one of the appearing options like netlock etc. the phone says "this phone is permanently locked" and there is no possibility to type in any code...
How the hell is my phone completely locked...
Hi I've been looking to xda for quite some time now for advice and help when I get stuck. First wanna say thank you! But I'm a new member so please correct me if I am posting in the wrong place or reposting. I'm aware that this is not a new problem, however, I have read till my eyes are bleeding and can't seem to find a fix. I have an sgh i747 AT&T gs3. I feel that this topic is unique in the fact that I have not rooted, flashed, altered or in any other way attempted to change this device. My fiance got the phone from her mom and I was going to try to use it with a straighttalk byop SIM kit. After activating the proper SIM with st the device would not recognize the SIM. I am now using that SIM in another phone. I get a constant ongoing notification in the notifications bar that says No SIM Insert SIM card. The device status is official and I have (as far as I know) stock ota updated 4.3 jellybean. When I insert a SIM into the device it doesn't prompt me to enter an unlock code. The only other SIM I tried to use is a sprint SIM card out of my freedompop lg volt. Don't know if that's compatible or not but I tried it and still the i747 acts as though it doesn't realize I've inserted a SIM. I called AT&T and emailed them. All I was able to give them was the imei as the phone number in my settings is unknown. The imei under my battery matches the imei in my device settings. They emailed me back within a few hours with my network unlock code and instructions for unlock. I haven't been able to use the code as my phone never prompts for the input of the code... I called them back later (this all happened earlier today) and spoke with a gentleman in tech support. I told him what was going on and asked him some questions. After doing a lot of research I started thinking that maybe my phone was already unlocked. Asked him to run the imei and said that it DID show unlocked on his end. That's one of my questions, if I still have an imei in my settings is this device still locked? The tech from AT&T told me it was probably the phone that was broke and I need a new SIM reader installed, to call Samsung. I tried to slide a little piece of paper in on top of the SIM that didn't work. I tried the dial code *#197328640# method, even though most posts say you must be 4.1.1 there are some who claim that it works on other versions. I tried a couple variations of this to no avail. I'm not sure what I'm overlooking here. If I'm leaving out any info that is needed to answer this post I'd be happy to include it just let me know. I need some fresh eyes on this thing it's driving me crazy I wanna get it fixed. I'm under the impression that I shouldn't attempt to downgrade this android version or I'll brick it... what the hecks goin on with this phone?! And again, sorry if I'm reposting but I can't find anyone who has posted yet that hasn't altered their device software in one way or another. I believe this s3 is completely official at this point. Thanks for any help you can offer
Is an sdcard recognized?
Was the phone ever used with a sim adapter? Sometimes, inserting and removing the sim adapter can damage the sim reader. Cheapest solution may be to purchase a new sim reader from eBay.
Sdcard works fine... and I'm pretty sure it's never been used with a SIM adapter
It's possible the sim reader has failed. Don't think you'll kn for sure until you are change the sim reader.
Yeeeah... I think I'm gonna attempt to change it right now and see what happens. I'll post back with the results. Thanks guys!
Fixed! Replaced sim port with spare one from an s3 sch I535 I had laying in the junk drawer with a broken LCD display. Posting this from my i747 on straight talk 4g. Sweet!
Glad it worked for you.
Yes and thank you again for responding to my post. This s3 is now rooted and titanium backed! Now excited to attempt to flash cyanogen mod later this evening. Thanks again and take care!
