ok dont know if it will work for you but it worked for me
add comma (,) in the end of the code
example:
*100*2# into *100*2#,
works for me

I have the same problem with my Defy.I cant make calls, send sms, check my credit..nothing.

[Q] [Fixed] Help! Cannot Send SMS with any ROM!

Hey xda,
My Desire has stopped sending sms's since i installed MIUI-AU 1.6.10 - used many ROMS before but never had this issue.
The first time i switched to MIUI i followed the instruction to flash the corresponding *.DX.zip file before flashing the ROM [see their site] which i did, then flashed the rom - all seemed ok and since then every time i send an sms to any number, from contacts/manually typed or what have you it gives an error - 'message not sent'
Since then, ive switched to the updated MIUI-AU,MIUI 1.6.17 (running currently), RCMix..whatver is their latest build - and im sure the issue will come back with any other rom.
Now obviously following all instructions and all i must have skipped something that is causing this..
Before flashing miui 1.6.17 i wiped everything and my SD card is setup for A2sd with the right partitions and extentions
Im running a CM7 HBoot if that matters.
If anyone has a clue please let me know here - im happy to provide any more information...cheers
Fixed: Guys if you ever get into the Messaging settings>Advanced>SMS Message Centre..don't change the default number stored there - i just called up my provider (Telstra) and they gave me the correct number to use and now everything is back to normal
Did you try to get the settings from your provider? You could try to reset them if you have got an account for the internet portal of your provider. You could also try to call them.
I don't know if you need special settings for every provider, but you can try this.

Thanks for the reply - phones here in AUS will normally get the settings as soon as you insert the SIM card but because i had deliberately messed with the sms message centre number i had to ring them to get that...your post got me thinking what i had changed and it just made sense

Connection Problem or Invalid MMI on every call

Hi,
Few days ago my phone shut due to empty battery, and after i started it again i started having problem.
Every call i make i get "checking USSD" something but its quickly replaced by "Connection problem or invalid MMI code".
The call is working and everything ok, but this message is annoying, i need to press OK on every call.
Any idea ?
Thanks!

Unfortunately, the process com.android.phone has stopped

HI,
I'm having this error message on boot and I can't find a solution. Every search I've made for this error comes up empty. The final solution being restore to factory. After doing that and trying to reinstall the rom I get the same error. Phone FC and i don't get time synched from the network anymore.
I'm not using TB. I'm not restoring any data. This is on a fresh clean install of the rom.
Any ideas? I need help!
What did you flash in terms or rom, mods, themes, and how did you flash?

I flashed the new Darkside rom with the TMO base. I'm starting to think that the new base is conflicting with my sim card... I'm not sure what to do about it... I'm with Virgin Mobile in Canada if that makes any difference...
No mods and no themes. Its just on first boot. Any other base seems to work fine. But since the TMO base I get that FC.
Could be a bad download, unlikely but if you haven't tried yet re-download the ROM
I've redownloaded multiple times and checked the md5... so the dl itself is fine... the install is fine... but once it connects to the network com.android.phone force closes... Do you know how to reset the network settings on the sim card itself?

Hi,
My HTC One XL from Rogers is doing this when the address book syncs in the car. I have it de-bloated, rooted, and unlocked boot loader. My problem is that nothing seems to have changed. The phone works (Bluetooth )in the car until the address book is synched (or so it seems), then it cuts out. What to do?
Same problem with my ROM. I am using Reliance GSM in India. I tried with Vodafone & Airtel SIM and the phone works perfectly normal. Tried with my Dad's Reliance GSM and the problem is back. Dunno what the problem is exactly. Other ROMs work perfectly fine with Reliance in my cell. Problem is only with this one ROM. Incase you stumble upon a solution, pl do let me know as well.
My Original ROM with the same error
Hello everyone
My phone is Samsung S3, with original software, it asked me to update the system and i agreed after that i found it add some information such as it;s from United Emirates but i live in kuwait, and now i have the same error only when i try to make international call.
please any help without reset the phone?!!!
On some ROMs, they say it has something to do with the DPI
I've encountered this problem on AOKP 07/09 Milestone 6, and from searching in the forums, all I could gather is that it has something to do with my DPI settings.
On 07/05 it was okay, I just don't get it why flashing to 07/09 made this error appear.
UPDATE Now I discovered that turning the phone into Airplane mode removes this error. But then if you deactivate airplane mode again it comes back.

[Q] Unable to search networks

Hi,
After flashing one of the CM11 nighties I started getting the message "error while searching for networks" when as msg says searching for networks, I found out too I can't use any USSD code I get the message "Connection problem or invalid MMI code" however I am connected to my local network and able to use LTE.
Flashed the latest modem version and for some time it works but now again it doesn't work, attempted flashing again and issue persists.
Attempted a newer version and switching to Paranoid and issue also persists.
Help?
My device is a SGH-i747m from Telcel (Mexico).
Does this happen with a completely stock ROM?
Sorry for late reply, my phone got bricked
Anyway, I was able to use USSD codes again after going back to 4.1.1 stock, therefore the problem is either 4.3 or the modem upgrade which disabled USSD codes.

Problem on calling LG G3 F400k

Hi there developers. First of all sorry for my so bad bad ENGLISH.
So I have purchased a used LG G3 F400k Korean Variant with 3GB of RAM and 32GB ROM. When I first used the phone it runs stock lollipop and all seems working fine, not to mention it's Battery life and heating issue. Until then I got boring with its stock Rom, I rooted it and installed a Bumped TWRP via Flashify. The Flashify says I am installing a recovery that can replace my boot, but I still flashed it. It was succesful as it directly boot me into TWRP. Now when I tried to reboot it gives me an error boot like that and an infinite black screen with disco light led notification. I have no memory card yet and so I get my laptop and searched for its solution here on XDA. I flashed it using unofficial lg flash tool with 2 files such as ott and I forgot the other one. It was succesful an I reverted back to stock kitkat. And now the problem I faced is I CAN NO LONGER RECEIVE CALLS but I can make an outgoing call and it takes too long to ring when I am dialing and my network here has a menu when accessing *100# but it always failed and it gave me an invalid mme code or connection problem. I then flashed a twrp back and before I did that I have already downloaded the Fulmics Rom and flashed it through TWRP, thinking of the problem is by the rom itself. It was succesfull again. But then again my problem didn't solve by flashing another Rom.. And now I don't know what to do my imei is still here but still I have this problem. Would be appreciated if anyone would just reply to my thread and provide me some idea
Sorry I can't provide you screenshots coz I can't upload due to restrictions to a new members.
My Internet is so good. It's fast. Its LTE. I also turned off the VOLTE calling and Call forwarding or call rejecting. But still, my family is having problem contacting me because their call is directing to my Voice Mailbox. I tried putting my sim card in other phone and it's fine. I tried putting different SIM card to my phone and still facing the same issue. I think it's a hardware problem? Please help me.! I haven't tried bringing this to shop coz it's very expensive and thinking of someone could help me here instead. Please HELP!
