Airplane mode causes loss of SMS message centre number - how to access Service Menu? - Nexus 6P Q&A, Help & Troubleshooting

Hi all,
My 6P has a weird problem where it loses the SMS message centre number if I turn on Airplane mode at any point. On stock Oreo I had to go in to the hidden service menu and manually set the correct SMSC number or text messages wouldn't work.
However, I'm now on ABC ROM and the same thing has happened, but using the dialer code doesn't bring up the hidden service menu anymore!
So:
1. Why is my phone having this issue in the first place?
2. How can I set the SMSC number on a custom ROM?
Thanks loads for your help! :fingers-crossed:

Thankfully, I found this app which opens up the hidden service menu so I can change my SMSC number.
The question still remains though: why does my phone keep losing the SMSC number?

where is the message setting number option

I have just found out that I can't send text messages, I can receive them just not send them. From talking to the phone company they have asked me to make sure my message setting number is correct but they couldn't tell me where it was and I couldn't find it.
Apparently this number is used when sending text, can anyone help by letting me know where this setting is.
I don't believe it is the rom or radio as since I found the issue I have been trying all types of roms and reverted my radio back down to 26I, no joy.
Currently I have CyanogenMod 5.0.8 installed

Dialing *#*#4636#*#* AKA *#*#INFO#*#* brings up a troubleshooting/statistics menu page. Dial that and select Phone information and at the bottom you can enter the SMSC (Short Mail Service Center) number. If the phone can receive but not send SMS it could be a carrier outage or issue 90% of the time. Morlin it is not risky to update the SMSC number. Kerorek gave the correct one for T-Mobile (12063130004). SMS is a voice issue and has nothing to do with data. Morlin try to update the SMSC number and powercycle the phone and test sending SMS.

for New Zealand the number is +6421600600
I had a similar issue some time ago. I remember trying to fiddle with various settings, but that didn't really do me any good.
I ended up wiping the phone and restoring all my SMS/Contacts/etc. Worked like a charm.
Just had this issue, after stupidly messing about in the very area I need to be in to fix it, ( pressed update smsc number with no number typed in, could receive messages, but not send them), full data+cache wipe did not fix this, nor did flashing other roms, since the SMSC reset wipes it from SIM I believe.
Looking up the correct SMSC number for my network and entering this fixed it however, and sms behaviour is back to normal.
So thanks for this, and remember folks, no matter how smart you think you are, all it takes is one stupid moment to remind you, you are just like everyone else

[solved] How to set sms service number?

Since yesterday my hero doesn't receive sms, only sends... Any one knows how to set again my operator's number (I'm under 3 Italia)?
just open your phone app and type *#*#4636#*#*
don't call wait for somting to open after that press phone info or soming like that (the top 1 ) afther that scroll down there is a box if you put the number there it wil do and press save
p.s. don't know the real translation of it form dutch
Entering the sms centre number doesn't affect incoming sms does it? Have you spoke to your network provider?
Tried your sim card in another handset?

Thank's to both, but the solution was that you indicated. I had a new rom installed without normal messaging app, and that - I believe - wiped somewhere the center number. Even changing the sim, all continued the same. But reinstalling the center service number in that hidden menu resolved...

[Q] Samsung Galaxy Express GT-I8730 [ROOT]: Force SMSC for stock messaging app?

(I hope this is the right place to post this.)
I have an Samsung Galaxy Express GT-I8730, unlocked, rooted, Android 4.1.2 and, after moving internationally and inserting a new SIM card, have been hit by the bug/feature as discussed in the threads [1][2], that is I cannot set the new carriers SMS centre for the stock app in its settings menu, the sending of SMS fails with the message "sending failed, review message and retry".

As entering the telephone service menu with *#*#4636#*#* does not work, I was left with having to install Go SMS and set there a custom SMSC, which enables Go SMS to successfully send, however the stock messaging app does not recognize that setting. I find Go SMS annoying and want to force set the SMSC number for the stock app without having to enter the service menu. My phone is rooted.
Question: Is there a way to forcibly set the SMSC number (possibly PDU encoded) without going through any menus, or is there a way to access the service menu even if I cannot access it using the special code above?
Thanks in advance.

Some weirdness with t-mobile service on 900v

I'm running the ok3 no bs rom, and I have root. I figured out my apn settings so sms and mms are working on my T-Mobile sim.I still have a couple of issues though.
1. How do I unlock band 4? I've seen a thread about it that says I need to activate a hidden service menu to do this. I followed the directions in that thread with no success. (E.g. change /efs/carrier/hiddenmenu from OFF to ON and reboot) every service menu code actually dials a number and gets me a recording saying it's not valid.
2. I've also run into a few problems with my touch tones not being recognized during calls. When I press the button I see the number in the dialer but the remote system does not recognize the key press. I've been looking for any kind of setting for this but have come up empty handed.

GS 7E T-Mobile (G935T) unable to change message center number and not able to sms

Hi, I'm using a G935T which is already unlocked, and I have no problem using it in Singapore with local network. However, the sms center number is incorrect and the phone prohibits me change it. I can find it in sms settings, but I cannot modify it.
The official doc simply says I cannot change it. (url not permitted for newbies and here's what they say):
To add or change the SMS service center number, follow these steps:
Note: We're sorry, but you cannot change the service center number. Follow the below steps to view the current number.
From any Home screen, tap Messages.
Tap the MORE icon.
Tap Settings.
Tap More settings.
Tap Text messages.
View the number under Message center.
Without that being properly set, I can only using calls and receive sms, but never send any.
I'm using the official firmware.
Anyone get an idea on this? many thanks.
I believe the same problem happens in G930T
