HTC Mozart SIM unlock

Hi all,
Just seeking some help, I've recently got a HTC Mozart and I've upgraded it to unlocked Mango. Problem is I bought it locked to Orange UK and I'm with Vodafone. I've just today got an unlock code and it's worked in accepting the SIM card but there is no signal and I can't call anyone. My contacts and messages have come up though.
Any ideas of what the issue could be?
Thanks for Looking.

Have you tried using the connection manager to switch it over to Vodafone?

Yes, I've switched it to Vodafone Contract on connection manager. I've rang vodafone to see if they are maybe blocking the signal as it's a new phone but because the sim works in my old phone they say it's 100% a problem with the phone.
Could it be that I typed in the code after I had upgraded to custom unlocked mango ROM?
And also I hear you have to type the unlock code twice on orange phones but I can't type it in again, there's no option to.

This phone was bought less than a week ago, I can and am considering returning it. I've rang HTC and they think it's a problem with the handset.

I too just got this phone like you, from orange, had it unlocked and have come to the conclusion it just doesn't work on vodafone.
When I did a search for networks on the phone tmobile, orange and 3 uk all came up but not vodafone. I also tried my 3 uk sim and it worked fine. i'm now back on my blackberry as it's the only phone i have which will work with the vodafone sim.
the phone i am keeping. vodafone i am not.

Thanks Livett, that's what I was thinking I tried a t-mobile sim and it worked fine. I think I'm going to change it for an Omnia 7 as I've still got a couple of months of my contract left and my other phone is a £10 vodafone branded phone. Worst phone I've ever experienced. I won't be staying with vodafone though.

Hi, I just thought i'd give you an update.
I updated to Mango last night on this phone and managed to get the sim working. It flits between Edge, HSPA and GPRS connections. Do Vodafone even have 3G? Either way it doesn't work, it's atrocious. I managed to send a text to myself on HSPA, recieved it, picked up the handset and then the signal dropped.
I think it's safe to assume Vodafone does work on this phone as it's unlocked, it's just Vodafone is so **** at coverage it's not even worth it.
Thanks.

[HELP] Can't connect to any network in UK

Hello
I have problem with my Sensation.
I bought phone year ago (on polish equivalent of ebay), from someone who lives in UK and he send me it to Poland. It worked perfectly there, till now.
Two days ago I came to UK, and since I switched phone ON after getting off the plane, I can't connect to any of the cellular network.
I am sure that SIM slot is OK because phone asks me to enter SIM pin code.
When I am trying to manually select network I got 'Your SIM card does not allow a connection to this network', and when automatically 'Unable to connect to this network at this time. Please try again later.'
Wifi and GPS working fine.
I dont have a clue whats the reason of that, where the problem lies.
Phone has ARHD 6.7.2 ROM, firmware 3.33.401.106.
Any help is appreciated as I need phone badly, to have mail and internet access throught the day :crying:
PS. I am starting to think that UK seller could scam me, and sold me phone with blocked IMEI or something like this? :/

Hi have you tried to change your radio And ril? This could help you regain signal. I can't recommend a particular radio and ril because we live in different areas and it will be different. However you can start by experimenting with the generic ICS radios and rils and see of one of those will reconnect your signal.best wishes.Hope this helps solve your issue!
sent from HTC sensation, soff, 3.33 firmware, viper Rom, sense 4.1, kernel version PYD-X stable 3.1, mugen battery 3800mah. Please press thanks if I helped in anyway.

Sounds like your Polish carrier/SIM might not be allowing international roaming. Get a PAYG SIM for a couple of quid and try that. That'd prove the phone side of things.

Try
Try putting in a diffrent Sim card to see if it's that.

If your home network doesn't have an agreement with UK networks then your SIM won't work, not sure if this is realistic as I thought they were all only to happy to help others take money from us. Try a UK SIM, if that doesn't work then your IMEI is probably blocked in the UK, but not in Poland.

It's a simple answer Your phone has been reported as lost/stolen in UK and IMEI has been black listed. It's now paper weight in UK.

Sorry for not mentioning - ofcourse I tried other sim cards, like o2 and vodafone - neither of it worked. My PL carrier sim worked in roaming in different phone.
So it looks like IMEI is blocked, I just wonder if I should go to the Police to check this out but I dont want to have it confiscated :/
Butif its true, Im not going to leave this scammer unpunished - I'll try legal action :/

Instead of legal action why not just find him and remove a thumd. maybe both thumbs to be sure.
The sad thing about having an IMEI number on the black list is that it can't come off that list. At least from my experiences.

Apart from it not being a paperweight. Revival is possible but ILLEGAL.

Wifi calling

Hi guys, new to here.
I've searched high and low and I can't seem to find an answer.
I'm from the UK and have a BTU galaxy s7. I've just rooted it and have downloaded csc feature expert. Tried to enable wifi calling but nothing appears under phone settings.
Has anyone had any luck doing this? If so, info would be much appreciated.

It worked for me in USA on t mobile!! i didn't do anything special just outta the box connected to wifi and boom

I'm in the UK too, vodaphone network with wifi callinging activated on my account and similarly I can't activate in on my phone, because there is no "wificalling" enable selection on my Samsung S7 Edge phone settings, did you have any luck finding out how you can do it

According to the Vodafone S7/Edge forum Wi-Fi calling needs an update before it can be enabled. No idea when this will be out.

It's working for me, but I got my S7 from EE.

OK Thanks. I contacted Samsung and they say wifi calling isn't part of their software, its a service provider software add on. I know EE have their wificalling working, where you download an App, whereas vodaphone are saying you don't need to download any app, so as you've said, vodaphone are advertising under false pretences, becasue their wificalling isn't up and running yet.....you'd think they'd get a system that works first, before advertising the facility......a case of waiting to see when Vodaphone get their act together

To be fair to Vodafone (which is very difficult) their web site doesn't mention Wi-Fi calling for the S7 - only the S6. Several people on their forum have claimed that customer service told them it was enabled which doesn't surprise me in the slightest. As the new flagship phone why wouldn't it be enabled out of the box? Especially given EE didn't appear to have any problem doing it.
Anyway, I'm sure it will be along any time now... What I'd like to know is when they're going to enable Wi-Fi texts as well as calls.
P.S. You don't need an app for EE either. I believe EE and Vodafone work in the same way as opposed to O2 and 3 which use a separate app.

I just flashed EE version (from here http://www.sammobile.com/firmwares/database/SM-G930F/EVR/) G930FXXU1APB9 and WiFi calling options still do not show up. Please advice.

AFAIK, there is no way to get WiFi calling on the Exynos variant. Sorry, it doesn't sound like it will ever be possible, so don't get your hopes up.

Well, as far as I know there is no hope...
I am in the same situation.
I wanted to have the chrome unlocked version, exclusive to Carphone Warehouse in the UK, so I got mine from CW.
I had many chat with EE and they say that most modern / recent phones support WiFi calling out of the box BUT not the XZP... It has to be purchased "direct" from EE so that it has the firmware that enables WiFi calling...
I asked to Sony support Why they don't include WiFi calling settings in their firmware, as Samsung, Apple, HTC, Huawei, Microsoft,... Do? . They simply replied that this is not their responsibility but the one of the operator... I, don't care!
So, the choice is simple :
XZP unlocked in chrome and no WiFi calling or EEocked black phone with WiFi calling...
I have 28 days return with CW... But will stick with the unlock one. Perhaps in the futur I will flash the EE Firmware, but for now, I don't use WiFi calling enough for that...
With some hope, but unlikely, maybe Sony will include the WiFi setting in their future firmware (if enough people ask for it?)

You dont need to buy direct from EE. It is enough if you just flash the EE version of the image on it https://xpericheck.com/cda/1308-6282
Check around in the forums how the flashing can be done.

Indeed, I could flash an EE firmware, but not sure how to troubleshoot if things go wrong !!! hence I will wait a bit longer for that... (and waiting for the ROM to be widely available.)..

My XZP is from O2. Ive got it unlocked and both O2 and EE wifi calling working. My operator is EE but it was cheaper to buy it from O2.

CW phone is unlocked to all networks so it has different firmware than branded unit. Look around for EE or O2 firmware to get wifi calling enabled.

I've just flashed EE firmware. Wifi Call works even better.

If Vodafone list it as a compatible handset when running their firmware then I don't see why not.

I would like to try this. But my phone is already setup and without root I can't use my trusty Titanium Backup to backup and restore all my apps and settings. A couple of questions I hope you have time to answer:
1. What flash tool did you use to install this? I found the firmware with Xperifirm, but it doesn't look like flashtool-0.9.23.1 is compatible with our phone yet.
2. Did this wipe your phone?
3. Does this firmware come with any EE branding or bloatware?
Thank you for your time.

@robdevil
What are the differences between the EE and Customised UK firmware?
Do you have a EE splash screen when starting and any EE bloatware / limitation?
I am also on a carphone warehouse phone and wondering if I should flash the EE firmware to get the Wifi calling ( I have it enabled on my EE account already and was used to use it in the past on a different phone)...
Thanks.
Tony.

Customized UK loads "telefonica_UK" configuration for any SIM inserted, which means no VoWIFI(wifi calling) or VoLTE. You definately need operator based firmware flashed to get Wifi calling and/or Volte.

No difference at all. My EE app is preloaded I think. That's it.

I can confirm this. The only differences that I noticed was the myEE app. And outlook security instead of avast security. I can't find the wifi calling setting in the EE rom though. My provider is supposed to support it, but I don't see any settings in the rom to enable it.
Edit: I checked with my providers app. It shows that wi-fi calling is not supported on my device. I'll try the O2 firmware to see if that works.
Edit2: Actually, I see the O2 firmware is still on the July security update. Security is more important to me than wi-fi calling. So I guess I'll just keep running the EE firmware.

Are you on EE pay monthly plan? You wont get WiFi Call or VoLTE if you are on Pay As You Go. You should see wifi calling settings if you flashed it correctly on both O2 and EE firmwares.

Hi Rob,
Thank you for taking the time to respond. I'm not on EE or O2. But my provider started to offer wifi calling on some phone models. Even if not purchased from them. For example the Samsung Galaxy S7 has it built in. But they don't support the Sony by default because it doesn't come with wifi calling built-in. So I thought it might show up with the EE or O2 firmware. But it didn't. I just need to go to my providers service point and ask them to force enable it for my phone to see if it works.

ishemes, so what provider you are using then and in which country ?

I'm with the provider Partner (used to be Orange) in Israel. Unfortunately they don't carry the Sony Xperia XZ premium phone. So no official support. The generic Israeli firmware does not have wifi calling in the firmware.

Quick Question
Sorry to jump on a slightly old thread...
I bought a Sony Xperia Z3 Compact for my other half. Brand new from EBay, unlocked, but doesnt have the Wi-fi calling feature, so from what I could find on a forum on EE it seems the Z5 compact has Wi-fi calling (the forum is giving instructions on how to turn it on specifically for teh Z5 and Z5 compact)
Only, reaeding this forum about phones having to be bought from the carrier to use the Wi-fi calling, I am now wondering am I going to be wasting my time buying a refurbed Z5 off Ebay, unless its locked to EE?
Thank you for any help!!
Gemma
P.S. I am the sort of girl capable of flashing, however i'd prefer not to have to do this, because I don't like interfering if I dont really need to

You might get more help by posting in the Z3 Compact or the Z5 Compact forums.
The way it works on the XZP/XZ1/XZ1c is via a set of settings overlays that are in the OEM partition.
Sony puts out different firmware for different carriers and the carrier specific items (like VoWiFI and VoLTE) are contained in the OEM partition contents of that carrier specific firmware.
If the Z5/Z5c work the same way, you should be able to get any E6653 (Z5) or E5823 (Z5c) model phone and download the EE customized firmware with XperiFirm and flash it to the phone. It should be the same as having bought the phone directly from EE with the same features and bloatware.
Again though, I don't have the Z3/5/c series and haven't dug into the firmware images, so you should check in with the people in the forums I've listed above.

OnePlus 7 Pro 5G Sprint APN problem

Hi there! Today I received my OnePlus 7 Pro 5G(GM1925, SPRINT), I bought it from a guy in a marketplace web we use here in Argentina, he brought the phone from USA and it's unlocked..so that the thing is for some reason with my current carrier(Tuenti here in argentina) I can get full signal, calls, sms but no mobile data and the APN option isn't available for me, it says " access point name settings are not available for this user" and there is no "+" symbol and all the option are greyed out. I try with another sim, from the carrier the previous owner has and it worked like charm, same with other 2 sim card from the other 2 carriers here, i take the APN with one of the carriers and I tried to modify it but it doesnt allowed me, the edit section is greyed out, with the other one i modify it but when i put the Tuenti sim card i get the "acces point settings..." I try everything from rebooting with wifi several times to hard reset and nothing worth...what are my chances here? its a really really rare situation, i contact the carrier and they say that is a phone problem
Do I need to flash another rom? Root it and modify it? i prefer not to touch anyting.
I really need to get mobile data with my carrier, thank you in advance! Cheers

Totally unrelated, but I had an HTC U11 that was sitting in the drawer that I recently tried to activate on sprint in the US. It gave me the same problem. I had service on this phone before with data. I reinstalled stock rom, tried two different sim cards. Calls and text worked but no data. I had to get a new phone so I just got a OP7pro 5G and am just reading through the forums on it. Hope you fixed it. But if you did curious what you did to remedy it.
