I can't call on my Miphone M88+ WM6

Hi boys and girls!
I have a quite hugh problem. I've just bought a chinese phone, a Miphone m88+ with Windows Mobile 6.
The phone works great, exept for one BIG thing.. I can't call =)
Let me describe the problem. I put in the SIM card in the phone, enter the pin code and the phone (most of the times) get a good signal strength and my provider shows up in the Today page. So far so good....
Now I'm trying to dial a number. It's dialing and dialing and after a short while three beeps turns up and the call ended with no success. I still have a good signal strength and it's looks like the phone has registred on the GSM system but I'm unavailable to call. Now I did a big NO NO and tried to call 112 (the european 911) and that works great! Okey, nothing wrong with the phone then.
Then I tried to reflash the phone with the ROM from this forum. The flashing went good. Back with the SIM card, perfekt signal but still no way to call. Off with the phone, on with the phone and off again and then it started to cooperate with me! The phone worked, the SMS worked! Happy! For an hour it worked perfectly and then i rebooted the device and then the phone went back to square one... BEEP BEEP BEEP...
I was thinking it might have been IMEI blocked for some reason and I have spend the last 24h to look for a IMEI changing software on the net and found a lot of them but noone works with my phone. And then again, after like 200 reboots during the IMEI tries, I could make a call, but just one and then back to null again.
My conclusion:
It's nothing wrong with the phones hardware due to I can make emergency calls.
The IMEI isn't blocked due to I can (sometimes 1 out of 100) make a call and send SMS AND I allways got my provider and a good signal strength.
I think it could/would/might be a configuration issue that Windows Mobile doesnt register to my provider.
What in the h*lls name could it be?! Any tips or hint from you guys?! Can it be the software dialer in the phone that don't like my provider?
Maybe any settings to change somewhere in the phone.. Timeouts.. ?
Is there a IMEI changing software for my phone so I can try to change it? (And NO it's not a ciminal act to do that in Sweden =) )
Please please help me!
Phone: Miphone m88+
OS: Windows Mobile 6 (Build 18165.0.5.0)
Processor: ARM926T OMAP850
Service provider: Tele2/Comviq, Sweden

SIM locked? And mount random ROM without brick the device... you are a lucky boy ^^ try with Sim of another Carrier.
D'rath

Okey...
Here's the deal...
Now I have been tried out another carrier (Telia) on the phone and the phone works perfectly. =)
Now to the problem. The Miphone don't have 3G (none of the chinese phone does)
The Tele2 SIM card is a newer card with access to both 2G and 3G network here in Sweden and the Telia card is a older card with only access to 2G.
I can use my new Tele2 card in older (2G) "normal" phones and then the card/phone just connect to 2G. But in this phone it looks like it won't work at all. Is there any settings i can change exept putting the phone on manual network selection?
I really need to use my Tele2 carrier and you can't order a old SIM card with only 2G access from the carrier =)
What to do? =)

[Q] Network problems with I9000 bought in Singapore, using in Canada

Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

getting signal with now sim card installed ?

as the title says , am getting a network signal in the status bar with no sim card installed in the device , where it used to show a stop or block sign before when there is no sim installed , don't know when it started but i have noticed it a week ago , and am on the 5.1.1 update ,
what i have tried so far :
1 - reset the device from the setting .
2 - reset the device with samsung smart switch for windows ( which download the latest firmware for the device & install it ) .
3 - installed the factory firmware with odin , and got the device to axiom telecom which is my warranty service provider , and the told me the have changed the whole motherboard , & after telling them the issue is still there , they showed me another s6 with no sim and there is signal and told me that this behavior is normal ( which i don't think so ) .
4 - contacted samsung directly by phone & email , and they told me to reset the device or send it to service ( which i already did ) .
so , is this behavior really normal ? are any of you guys getting this ?
my device : SM-G920F
country : Saudi Arabia

no its not normal
if you type *#06# you gonna find IMEI become 3500000000006/01
if it is then you cant make calls or send sms ( not registered on network )
its the same problem like me i don't know where this come from but we need some one to give us backup the EFS folder. to restore it back to the phone SM-G920F
please if some one can help us thank you

no , it seem we are having different problems ,
*#06# reveals normal IMEI ,
and i can make & receive phone calls & sms if i install a sim card ,
try resetting yours to stock ,
other than showing a signal with no sim card installed the phone is fine & doesn't have any problems .

Speculation- you'd need emergency service call? I would assume that it's allowed to connect to network for that and not have phone disabled?
More speculation- your being spied on...
-Spy
It's only a display icon. You aren't able to still make a regular call without the sim? If it ain't broke don't fix it.
But to ease your mind just check the network status in your settings. Should say what connected to.
Surely it does have to do with the update itself if your phone still functions as normal.
I'm sure there is a network status with the super secret spy codes that you enter on your dial pad. You know the #secretrandomnumber#* codes...

it could be there for emergency calls ,
in terms of being spied on , ha ha ,i don't think so , the service center changed the entire motherboard which include the eMMC with it's whole partitions .
the sim card status in the settings says Not Available for everything , and yes i can't make calls nor sms without the sim ,
but you still didn't answer my question : do you get this when you remove your sim ?

no one with a similar problem ??

I've seen it on lots of Samsung phones. It's simply a signal for emergency calls. You have to be able to make emergency calls with or without a Sim and that's telling you how much signal you have.
Seriously people this is pretty simple and no conspiracy.
You only get a circle with a line through if you have a sim card installed that is blocked from the network or the phone is stolen / blocked etc.

good to hear ,
what made me think it isn't ordinary thing is that the service center didn't know about it & thought it was a problem ,
thanks a lot .

This was done on last update Samsung gods thought we needed to know how much of a signal we had for emergency calls

Having the same problem with my samsung galaxy s6 SM-920F. showing bars on the signals even without sim. not connecting to network operator as well. showing Disconnected status in SIM status from About.
Tried updating the software even downgrading, factory reset and wiping cache but nothing worked.

Found this thread when looking for an answer to this question. In my case, it is a tablet that hasn't even got a sim option but still has the mobile network signal showing, even when airplane mode is switched on. Just worry it is eating some of my battery life. Any ideas?

I am also getting same problem.
There is no sim card inserted in my phone but still it shows the network bars.. Your And my problem is same.

There, an actual answer. Guess I should add it here since I wondered the same thing
a sim card has nothing to do with the transceiver system of the phone. its literally a "passkey" it is your authentication to USE that network. ie you can always SEE the network you just not allowed to "use it" without permission hence the simcard.

I own an GALAXY S7 EDGE AT & T ( G935A )
Yesterday on morning i was talking on phone and after 1 minutes 17 sec phone loses carrier signal and after 2 sec of losing signal the phone reboot automatically then was very slow. I rebooted the phone, and it showed that havent SIGNAL there and instead CARRIER SIGNAL i see the circle with diagonal line there.
I wait some minutes for the signal but again the same, i make some restarts but again the signal doesnt work, just displayed circle with diagonal line. Then i make RESET FACTORY and after configuration was the same again, i update to nougat 7.0 but again was the same error, i downgrade to ANDROID 6.0 but again doesnt work.
The wi-fi works perfectly with no problem, but I can't make a call, send sms, or mms, or use mobile data like 2g 3g 4g lte or gsm.
Any ideas how I can turn the radio on? I've rebooted several times and toggled the Mobile Data button, but that isn't doing anything.

Have you looked in system settings to verify that your network/SIM settings are correct?
Here are some dialer menus for S7 and S7 Edge. You're looking for the menu that let's you check the status of your radio and allows you to turn the radio on/off. See if it will let you turn the radio back on.
http://www.samsungsfour.com/tutorials/all-secret-codes-of-samsung-galaxy-s7-and-galaxy-s7-edge.html
Also, try a different or new SIM.
Are you sure your service wasn't disconnected by your carrier? Have you called support?

If you read their first post, they still have their IMEI number, it is still listed where it is supposed to be in settings.
Checking IMEI would have been my first suggestion also but they have IMEI so I didn't bother mentioning it.

Did this just happen on its own, did it happen after you updated the device?
If you bought the device used and you ran into this issue when you tried to activate it, it might be a device that someone didn't pay the phone bill and the devices blacklisted. If this is the case, there's nothing you can do until/unless the previous owner's existing bill is paid, then the block will be removed.
