Sounds to me that you are locked to a single carrier. Just unlock your phone (search the Wiki - start in my sig). Your carrier won't notice this unless you need to send your phone in for warranty repairs - but there are also ways round that.

Unable too make phonecalls

I found a HTC S730 and I have updated the ROM to WM 6.1 (Alc) But I cannot make any phonecalls or recieve any and I cannot recieve or send text messages. I have taken the phone to a local phone shop and he said the phone has been blocked, this is a very nice phone and I would like to use it too make calls, is there any way I can make the phone features work again?
Thanks in advance

I suppose you are able to switch it on and get into home screen right? So, are you able to navigate through menus etc...? If you put a SIM card what happens? Is the phone able to find and log onto the network? Give more technical details. Not just conclusions of your tryings.

or as your last chance you could hard reset your phone, or flash another rom...

I think his radio is dead. Otherwise, he wouldn't be able to get into writing SMS and then trying to send those, and failing... If the phone was locked, it wouldn't allow him to get into GUI or Home Screen. Or it would say that the SIM card is not accepted (locked to a specific network).

if it is Operator locked he need a SIM UNLOCK, but don't know if it is work for the wings...

Okay sorry about the lack of technical information. When I found the phone it had a password so I performed a hard reset by holding the two soft keys and pressing the power button, I then flashed the ROM to Alc's WM 6.1 . I inserted a T-Mobile sim card and on the phones home screen it says 3G T-Mobile and there is clearly signal but the phone will not make any calls or send text messages, is there anything I can do?

So what happens exactly when you press the Call button? Does it give any error message? Or it just doesn't do anything?

It looks like its about to ring then it just makes a beeping sound and says 'call ended' ive tried all sorts of different sims all with the same outcome.

When you brought it to the phone shop they told you the phone had been blocked, that possibly means the IMEI number of the phone is blocked so no sim would work in it.
Have a read of this

I never experienced IMEI blocked phones. However, if you can't make it work, there is one possibility. You can send it to me and I can try it here.

GS3 LTE not registering sim card

hi all
i have a weird issue with my GS3,
it worked well until i put it into flight mode over the weekend as i was out of service, and then upon taking it out of flight mode, it is not registering on my network.
i have tried my sim in another phone and its all good, and i have tried other sims in mine and it wont work. so i have narowed it down to the phone.
it appears as though i HAVE NOT lost my IMEI, as (*#06#) matches the number ib the battery compartment of my device. and the phone still functions as per normal, with the exception of the sim issue. i have tried to clean the contacts and also push the sim down during boot and loading to determine if it is just making a bad connection, but still no go.
i have a symbol in the notification bar that looks like a greyed out sim card with a slash through it, but i have not been able to find the symbol anywhere to determine what it is.
i am running "Turbo rom v4" and all was working well until the weekend.
and suggestions as to what to do?

Galaxy S4 mini get no connection after Net-unlock?

Hello!
Ok, my Samsung Galaxy S4 mini had a netlock on the network "3AT" - if i put in an other sim-card than one of "3AT", it asks me of
an netlock-unlock-code. First i tried to load other roms in the phone, also some cyanogenmods - but logically it doesnt worked .
Good - the next step was, to get an unlock code and put it in the phone as it asked med. OK, its says, that the netlock was gone
and the message to give in the netunlock-code never appear again.
But, if i give in an other sim-card than a "3AT": it knows the sim, it asks for a pin and it shows that it is connected to the specific network,
also shows me a signal strenght, ok - but if i would do a phone call, it says "no connected to network". I have tried everything - factory reset,
load other ROMS, also cyanogenmod, but nothing happens, always the same problem. I also tried different sims, no one worked, only the
original sim from "3AT"?
One interesing thing: there shows me a complete wrong phone number in the settings under "own number"???
Any idea what i could do?

I need help reactivating my SIM which mysteriously stopped working

Hi I am in need of some help. I will try to give as much detail as possible.
I was talking on the phone 3 days ago and suddenly my call was cut short. The signal icon at the top was greyed out and it had a little x in the bottom. I tried to figure out what happened and at first I thought the cell tower went down because I was unable to connect to 2g, 3g, LTE/4g, nothing.
Next day with my father visiting my house, I tried his phone, put in my SIM, it works, there is signal (nothing greyed out) and I see the name of the phone service at the top left "Personal". His phone with his SIM works as well. Cell towers are working fine. I put my SIM back in my phone, no signal, not able to make phone calls or receive text messages.
At this time WIFI, Whatsapp, the phone itself works. I double checked APN settings from the carriers website, everything matched. I tried rebooting the phone, reseating the chip, selecting towers automatically, manually, and read many many discussions on the web none of which helped. I decided to do a factory reset. Backed up all photos to the computer and proceeded to reset it to factory new. Put in the SIM and same problem. Oh I also in the meantime have spoken with my service provider and they do not see anything wrong on their end.
So now I proceed to restore the phone from a backup on my MI account, all apps restored. Now I try to use Whatsapp and it wants to confirm my account with a text message, that is a problem because I can't receive text messages. I went to my service provider today, they put in a store SIM with a different number and it worked, they assumed I had a faulty SIM and gave me a new SIM with my number, same problem. Now I think it has something to do with XIaomi or MIUI or my MI account. I log into my MI account from my computer and try to add my email under security and it won't let me because it needs verify my account by sending a text message to my cell which of course is not working.
I am thinking of rooting the phone but I imagine I will somehow be blocked there too.
What happened to my phone?
Is my account being protected in some way MIUI, XIaomi or my MI account preventing me from activating my SIM?
Everything I try to do requires a confirmation text.
I want to root the phone but in order to do so I need to request that Xiaomi unlock the bootloader which will require a text message which of course is to be sent to my phone that wont connect to the cell tower.
Was I hacked or spoofed?
How do I go about fixing my situation?

Have you tried changing region and changing back to your country again? That may be possible reason.
For confirmation of code for bootloader unlocking, while applying put your sim card into other phone and that way you'll be able to get code and bootloader unlocked and can flash and try with different rom.
Similarly if your device is out of warranty then you may want to check with the antenna cable inside phone if that is got disconnected or got loosen. I don't if this would have happened or not but this could be issue. Process with precaution if you do so,I won't be responsible for anything.
