Someone help a newb out? O2 Cocoon...

I apologize if I'm posting in the wrong place; but I've gone just about everywhere else looking for help...
I'm in the USA; and I've got an O2 Cocoon - I'm trying to find out if it's got a simlock on it, or if it's just messed up.
The major problem is that it absolutely refuses to make or accept calls, texts, mms... anything.
The phone is set up for my network (Unicel) with what I'm reasonably sure are the correct settings. It gets bars of signal, and when I search for available networks, it finds a 2G Vstream. When I have new voicemail; the new message icon even displays on the Cocoon, and after switching the sim to a phone that does work & checking the voicemail, the new message icon on the Cocoon goes away.
It constantly displays "SOS Call Only" underneath the signal bars; even though it's usually getting 3-5 bars of signal, and whenever I try to connect to the 2G Vstream that it sees in Network Connections, or make a call / send a text; it says "Network Failure".
Does anyone think the phone might actually be simlocked, even though it's not asking for a subsidy code or anything? If so; how do I access the area of the phones software where I can input an unlock code once I buy one?
I'd really like to get this phone working; however I don't want to spend the $40 on an unlock code for the thing if I'm not even sure that it's going to solve my problem.

Sweet! That's exactly the type of answer I've been looking for. I've been shooting emails back & forth with O2 support; the one I most recently sent them I straight out asked for the code & explained my situation - if they don't give it to me in their reply, I'll just buy one now.
Chris, Do you know the sequence / code whatever that I have to enter in order to get to where the phone asks for the code?
My only experience with unlocking is a couple of Motorola Razrs; and those won't let you do anything at all with a different sim if they're locked - they just prompt you on startup.
Hopefully deblocage-htc.com 's turnaround time to send the code to me is fast; I can't wait to start using this phone... it's so, awesome.

OK; so after sending deblocage-htc.com about 3 emails asking them how to enter the subsidy code on this phone; they finally responded with one that wasn't an advertisement -
"Dear Sir,
Your phone must ask to enter the Unlocking Code just after entering the PIN Code of your SIM Card"
The phone isn't asking me to enter the subsidy code after I enter my Sim Pin. Lot of good buying an unlock code is going to do me if no one seems to know how to enter the code into the phone
EDIT: Wait, does that mean I just enter the unlock code directly from the home screen of the phone, then?

want to help mate but the info I have is that if you enter a non o2 sim will ask for the code

02 cocoon start up only
hi mates i have 02 cocoon here. the problem is when i turn it on only star up continuesly not booting.
how can i program this or hard reset?
pls help me.tia.............

The phone is definitely not locked. It works just fine with an AT&T simcard borrowed from a friend, but does not work with a Unicel sim. It doesn't prompt me to enter a subsidy/unlock code when I turn it on.
I thought it might not be compatible with GSM 850, because we only get 850 where I live - but when I'm roaming in NY or PA or anywhere in between, and there's loads of 1900 signal as well, it still doesn't work with my Unicel simcard. The phone sees bars of signal, and it knows when I have a missed call or a new text message; but it won't let me call out or receive calls or text messages or do anything useful like that.

How do I resolve "Failed to make videocall"

Maybe it's me or my network operator, but i can't get videocalls to work.
Pushing the videocall button gives me the screen with two cameraviews. It starts dialing and then i can see the phone icon go from 3g to H
But then it quickly say's : "Failed to make videocall"
Any suggestions? (been searching this forum and many others without answers)

I can't get it to work on my 8525 or my tilt I'm with [email protected] I think it has to be my network operator. My's does the samething also.

Of course it doesn't work with your phones. Neither the 8525 or Tilt have the forward facing camera, and the AT&T network doesn't support it.

More info is needed.
Which hermes rebadge do you have?
Who is your cell phone carrier?
Does your icon go back to 3g, or does it stay at H?

Better call your mobile operator for the instructions to set the problem.

Why does it not work with Orange then? Surely one operator must allow Video Calling?
Same error..."Failed to make video call"

"Failed to make video call" means : Your operator must to allow video calling for your sim card (extra payment).

On the blow-err now 2 Orange....usual green sleaves......will let you know
)

Just to add my tuppence (two cents for our American friends):
I did a video call about 18 months ago, when I first got my Hermes. Then I tried again a few weeks ago and got "Failed to make video call" as soon as the dialer screen had finished coming up. It was way too quick for the network to have tried to connect the call, and I knew I had Video Calling on my account (from the one 18 months ago, hadn't made any changes since).
I spent three days recooking ROM's, trying out different ones and even trying a standard build (that was a culture shock, it's been so long!) but EVERY ONE had the same error message.
Finally, I tried my SIM in my wife's phone, and the same thing happened on her Sony Ericsson, so I called T-Mobile. Yup, they'd somehow lost my video calling on my account! I asked for it back, she put a tick in the "yes" box on her screen and I was able to make a video call as soon as I'd finished on the phone to her.
Moral of the story is to call your network to see if it's activated on your account. Even if you're sure it is, call them to check rather than waste 3 days as I did!!

thank you all for your input.
i've a hermes with two camera's. can't be the problem
i've tried om a dozen wm5 and wm6 rom's including shipped ones
i've asked friends with hermes phones as well, they don't succeed as well
but the simcard switching, network operator thing might be the one, i'll try that.
weird it is. an operator can make a lot of money on my phoneuse when making videocalls. why shut it down?

[Q] Defy Emergency Call Only

Hello all,
I am new here, My name is Lewis, and you all seem like a very clever bunch of people. So i was wondering if you could give me some help with my Defy.
So here we go:
I bought my Defy last week after my Nokia died, it is second hand, and was locked and branded to T-Mobile (UK). I got it unlocked a few days ago, and it unlocked straight the way with the 1st code. So i assumed all was well. After trying to send a message, i realized that it was stuck in 'Emergency Call Only'. After a bit of searching around the interweb, i found that i had to check my APN Settings. The sim card i have is with Tesco Mobile, so i found out the APN settings and all seemed fine. I have tried hard reseting the phone, but still no luck.
It is all standard, so do i have to do any flashing to get it to have signal? Thank you for your help in Advance.
Motorola Defy
Locked to T-mobile
Unlocked to work with Tesco Mobile sim (O2 masts)
4GB memory card
All default.
Edit: When I 1st put the Sim Card in, it has signal for a few seconds before reverting to emergency calls only.
wrexe

can't find signal

hello everyone
so i've recently bought lg g3 phone model LGLS990
everything works just fine until i go into mobile networks and change the preferred network to LTE
when i do that i lose my phone signal and all i can do is emergency calling, it's like there is no sim card inserted anymore
and when that happens i can't even change the preferred network to gsm again
but before i've done that i could've used phone for calling and messaging and internet but internet wastes my credit tho i've got a data plan and it's way too slow
i think this is related to my threat each time i turn on the phone a dialog box appears says: "hands free activation contacting network"
a couple of seconds then it fails and there is an option that says activate when ever i click it, it tries to reach my mobile network provider i suppose but then it fails too showing this message: "Sorry - we experienced a system problem during your task. please dial *2 from your Sprint phone or call Customer Care at 1-888-211-4727 from another phone to complete your task."
**im pretty sure that the sim is okay since i use it on my old galaxy s3 phone and i use 3g just fine
**i've tried to change the preferred network to all of the options listed
**i bought it new but the seal wasn't on the box tho it couldn't be used i guess since the screen sticker was on it
**the one i bought it from have brought it from another country but it's not shown that the phone is locked, i've never used a phone with a locked sim so i really don't know how is it like :/
**when ever i open sim toolkit i find the network provider's name there but when i click on it it keeps loading and nothing happens
**the android version is kitkat 4.4.2
sorry for any language mistake and sorry for my modest knowledge
please reply asap so i can try to contact the guy i bought the device from and try to get back my money if it's unsolvable issue
thanks in advance

Stock Rom Carrier Unlocked not able to receive/send calls but can use data and SMS

Hey,
So I bought an LG G4 from Vodafone UK and unlocked it so i could use my Three sim card.
Weird thing is I can use Mobile Data and send/receive SMS if I am on 4G. The person who is calling me can hear the calling tone as if they were calling someone but I don't actually receive the call.
When I switch to 2G/3G it simply does not connect to the network.
I have done a factory reset and it did not fix the problem.
Any ideas?
Thanks
tl;dr : can't send/receive calls but can use data and send/receive sms (through 4G only)

Maybe you need to register your IMEI on the network? That's what I had to for At&t.

How would you go about doing that? Apart from manually searching for networks (I can see other carriers like O2, vodafone, EE, but I can't see my carrier Three ; the person living in the flat with me is on Three as well and they have no problem, so it's not a coverage issue. I have bought the phone from vodafone, unlocked it and trying to use it with Three).
Do I have to call Three for this IMEI registration or..?
Thanks

Best bet will be calling your service prover and have them register it. I had to call At&t and have them register my IMEI since I couldn't use internet or make calls.

Just had a long chat over the phone with them and in the end he said the 'engineers' found a 'problem' on their end and it should be fixed in @5 days. He didn't want to mention what problem or how / why it happened. Oh well fingers crossed.
Thanks!

update : so after about 4 calls with customer service (across 3 weeks) and 2 trips to the 'Three' store i'm basically stuck and would need your help guys.
backstory : I've contacted them once at the start of January and they said they found the issue and they will fix it by 7th of January which didn't Happen. On 7th of January they said they are sorry and it will be fixed by 14th of January which didn't happen either. After that I received a message that the problem was fixed and if i had any other issues I should contact them, which I did because the problem was not solved. Yesterday I went to the shop again and the 'tech' guy told me that it should be working and he gave me a new sim card just to be sure, and if that didn't work he said call customer support and ask for contract cancellation. Today I got called by customer service and I have told them that it still doesn't work and I'm paying for something I can't use and I've been told to request contract cancellation which they didn't believe and said I have to pay the rest of the contract length in order to cancel, which is absurd. I went again to the shop and the new customer service person that was assigned to me said they don't have any tech people and she seemed she didn't believe when i said i talked to one the day before. She tested the sim on their phones and it worked and also she took my phone "in the back (strange cause she said they don't have any tech)" and said I had my phone set to 2G (which I didn't, it was set to 2G/3G) and that that was the problem. strangely, for that split moment i had one bar for 3g and the call went through. Straight after that phone stopped working (it was just that small area in which it worked). I told her that that's not the problem and she's like "welp you didn't make your contract at the store, you made it online so I can't help you , you have to call customer service". So I'm basically stuck with a contract which I can't use and I have no idea what to do.
problem : I cannot register to the Three network (only in small random areas, few of them) but I have no problems with other SIM cards from other Carriers (Orange, EE, Vodafone, O2). I have bought the phone from vodafone and unlocked it and last time customer service told me they can't give support to phones that were not bought from their store. So I'm stuck here with a phone contract which I can not use to make or receive calls, but I can use the mobile data and send receive texts. I am considering rooting it and puting a custom ROM , although I'm not sure if that would fix the problems (maybe issues with certain bandwiths?.
Any help or ideas much appreciated!

Same problem here
Hi all. Same problem here but different issue.
Origin : G4 buy used on November. IMEI fully working and not blacklisted (calling my french phone provider this morning, it tell me that's IMEI is ok and phone not stollen and it try to repair remotly my carrier but didn't work)
Problem : Fully working since i picked up a call and answer ... and then when the call is finish i tried to call someone 10 minutes after and totally loose signal(connection) (Orange/Sosh)
What i've maid before : Playing a lot @ a boring but adictive game. High temperature since 3 days because i play a lot but temperature decrease when i stop playing.
I've used a legal app to record a patern and make some actions without my intervention (RepetiTouch Free (root)) to make races in the game.
That's all ! No drop, no hit, nothing ! Just playing, having a call, hang off and then want to make an other call and nothing.
Since the last 6 hours : Signal ok - Data ok (can go on internet / GAPPS etc..) - CAN receive and send SMS (i've don't trie MMS) !!! but .... can't receive and can't send any call.
I was on Genesys 3.5 and i've update to 3.7 when i see the problem, believing that's it will fixe the issue but ... no ....
Formating and going to stock ROM but with root SU etc..... Can't receive and send call too ....
I'm going to back to stock with KDZ .... but i really believe that's it will not work .....
AND .... to finish and kill my joy .... i've unlock bootloader with LG tools since 2 month .....so my phone is no longer under warranty.
My SIM card work on others phones ... other sim cards didn't work in my phone ....
If anyone have this issue ... please tell us

Sorry bro cant help you here. Never heard of that problem before but my idea is that you should refund that phone back to Vodafone UK.
