Phone number on SIM is wrong - Huawei P20 Lite Questions & Answers

I was long time user of one telecommunication provider. When I transferred to the new provider I bought their SIM card with a temporary phone number. Because I wished to transfer my old phone number to use with my new provider, they needed a couple of days to do that and at that time I used both numbers (the old one with the old provider, the new one with the new). After a couple of days they transferred my number and I was able to use my old number with my new SIM card from my new provider.
When I was using the stock firmware with EMUI 9.1, most of the applications recognized and used only my old phone number (the one I transferred from the old provider and I use to make calls). It was (AFAIK) also the only number shown in Settings -> About phone -> Sim status (Slot 1) -> Phone number on SIM. On custom GSIs like LIR and CAOS most applications use my "new", temporary number.
Why is that and is there any way to fix it?

Replace card that wont send SMS with another one (same number, but new SIM card). You can ask your operater to do that. Maybe they will charge you with some small ammount of money. That solved my problem.
no, its two diferent operators.
i install other rom...
same ****...
i realy dont know what to do.
i try diferent sim card from same operator and no music for me again.
Same problem. All options are checked up with the operator, changed SIM cards, but the problem remains.
You should change sms service center number with the one from your carrier.

I change 2 SIMs, 5 ROMs/radio, and every time check all settings (service center number included), but....
every time "not possible sending SMS"

[SOLVED] Mobile connection and SMS stopped working after messing with ROMS

Hi guys,
few days ago I've decided to move forward with Fusion Update 7 ROM to Fusion Update 8. Procedure was about normal beside the fact I had also purged SD card. Upgrade went well, but:
I cannot get mobile connection
No SMS can be sent
No matter which ROM/RADIO I had flashed after my previous move everything beside those two is working. So I can get WIFI connection or receive SMS, I can also call and receive calls.
My configuration:
- Hardware: HTC HERO GSM (white)
- Recovery: AmonRa 1.7
- ROM: FROYO_2.2_elelinux_v2.2 (at the moment)
- RADIO: 63.18.55.06OU_6.35.15.01 (at the moment)
Additional info:
- SMSC is set correctly (checked using *#*#4636#*#*)
- APN list is correct
- rollback to vanilla 1.5 ROM from RUU not helped
- other SIM cards from other carriers work the same way
I trying to get some debug information using adb, but only thing I can find is that ppp connection is missing in netcfg.
Do anyone know how to initiate Mobile Connection through adb shell ? or anyone get similar problem before?
Thank in advance,
Problem solved. During messing with ROMS my SIM card must been somehow damaged.
After more tries with other SIM cards my phone started to work finally.
You are missing the correct apn settings for your mobile data and also missing or have the wrong SMS service number, have a search on the forums here, or Google and you should find them. Always worth backing these up or writing them down, as not all rom's have necessarily got all providers son's included.
Sent from my HTC Hero using XDA App
Thank you for fast reply.
I checked those before:
SMSC:
- refreshed with *#*#4636#*#* and those looks correctly for my carrier
APNs:
- there where missing fields in APN config which I've updated according to carrier configuration
Still nothing had changed.
I assume that it must be some kind of config that do not change between ROMS.
(I will update first message with those info.)
Did you checked with an other SIM/carrier?
Yes I did.
Effects where the same.
I've also rolled back to vanilla 1.5 ROM from RUU. Nothing changed.
It must be some kind of external configuration that is not changed via ROM replacement. Can this be true?
Thread moved to Q&A.

[Q] whatsapp help required

-I was using whatsapp with my number on my android handset till it lost SIM card functionality due to falling and stuff

-I'm going home and would leave the old handset there (after doing a factory reset) and will buy a new one.
-So if I put the same SIM card in the New android handset then would I able to have whatsap with the same number?

Can a phone prefeer some operators?

Hi,
my no-brand Galaxy S III GT-I9300 was working fine running CyanogenMod-13.0 nightly with my Vodafone Italy sim card, until I used for some weeks a sim from the italian operator Tre. When that contract expired I discovered that my phone didn't accept anymore sim cards from the italian operators Vodafone and Wind (it shows a message complaining that there is no sim card), while it works fine with the italian operators TIM and Tre. Sim cards that my phone doesn't accept are well working in other phones.
Previously all sim cards of all operators where working fine.
I tried the following with no result:
1)- wipe all user data;
2)- install the original Samsung firmware JSS15J.I9300XXUGOE1, followed by another wipe user data;
3)- restore from a full nandroid backup, including modem, system, user, cache partitions and EFS, taken when everything was working fine.
I've checked my IMEI number on some websites and it seems to be clean.
All the hardware in my phone, including the sim card reader, should be fine because everything works when inserting TIM and Tre sim cards.
Can anyone give me some help?
Thank you in advance.
It is very possible that tre have locked the network lock but not only is it bad practice but also at the end of any contract, providing it is paid up in full, the operator is obliged to unlock the network lock free of charge.
The best way to start is to call tre and ask if they have put a lock on it but just habe a look at the sim cards first and make sure they are the same where the gold contacts are.
If the other sim cards were active and not used within a certain timescale, usually 6 months, the sim card will be remotely deactivated and the number returned to the pool for someone else to use. Im this case you must realise that you simply "lease" the number from the operator. You never own the number, only the simcard it was attached to.
If your rom is 4.2 you can unlock it yourself by changing a byte in nvram, very easy to do.
If your phone has ever seem 4.3 or later you can't unlock it without a proper network key.
A word of warning though. Be careful with the efs partition.

All calls only connect to "Emergency Number"

Hi,
Did anyone come across the problem that when you insert the SIM card, the carrier is found, data works, but when you try to dial any number, the phone app only connects you to the "Emergency Number"?
I did test the SIM card in a Redmi Note 4 and Huawei Y550 -> calls and data works fine.
The problem on the Redmi Note 9s started "out of the box":
-stock FW MIUI 11.0.7 -> carrier detected (3 Ireland), data works but any dialed number goes to "Emergency Number"
-unlocked BL and installed LR TWRP, then crDroid -> data works but calls only to "Emergency Number"
-installed MIUI 11.0.9 fastboot with MIUI flash "flash all lock" -> data works, no calls other then "Emergency Number"
-installed MIUI 11.0.3 EEA (flash and lock) -> data works, still no calls...
-unlocked BL again and installed LR deep and EvolutionX -> data works, all calls to "Emergency Number"
I did test also SIM cards of Vodafone Ireland, eir and lycamobile Ireland. These cards work in other mobiles, only in my Redmi Note 9s calls are not possible other then to the Emergency Number, while data work just fine.
In Settings/SIM cards & mobile networks/Default Settings "Dial" and "Internet" are greyed out, "Dial" is locked to "Not set" and "Internet" is set to "3". This is the setting in MIUI 11.0.9 and similar with the other Roms.
In Settings/Apps/Manage apps/Phone is the default "Phone" app. (MIUI 11.0.9, similar with other ROMs).
EDIT:
Found a partial fix, see next post
Heureka
at least I found a partial fix for MIUI 11.0.9, tested with prepaid and billpay SIM of 3Ireland:
- both SIM work in my other mobiles Redmi Note 4x mido (LOS 16.0-20200407 official) and Huawei Y550 (LOS 14.1-20190912 unofficial) BUT when checked in Settings/Network& Internet/SIM cards/SIM slot 1 the operator name and the number are unknown and not accessible to be modified. Nevertheless both SIMs work fine in these mobiles for calls, messages and data.
- in the Note 9s with MIUI 11.0.9 the SIM cards DON'T work "out of the box". After the first boot data work, but all calls are "diverted" to the "Emergancy Number" 112/911. In Settings/SIM cards & mobile networks/SIM CARD SETTINGS and "clicking" on the SIM1 or SIM2 symbol it is possible to enter the international format (e.g. for Ireland "+353xxxxxxxxx") in "EDIT SIM INFO/Edit SIM card number". In the field above it "SIM card name" the operator was displayed corectly, for the bill pay SIM "3 IRL" and for the pre pay SIM "3". After assignig the numbers to the SIM cards calls are now possible, with ONE EXEMPTION: calls to the Customer Service number 1913 are diverted to the "Emergency Number" 112/911. If you are with 3Ireland, you can call 083 333 3333 instead of 1913.
- I did it this way:
1. Fresh boot of MIUI 11.0.9 (installed MIUI fastboot ROM with XiaoMiFlash), with the prepaid SIM (registered number with the Mi account), entered my google account and Mi account during the "MIUI 11" setup,
2. entered the number in "Edit SIM card number" and calls where now possible with this SIM exempt the 1913(see above),
3. turned of the Redmi Note 9s,
4. put in the 2. SIM (this number was not asigned with te Mi acount) and turned it on,
5. during the boot process, the change of the SIM was recognised and I was ask to register it with the Mi account and to enter my password,
6. entered the number in "Edit SIM card number" and calls where now possible with that SIM exempt the 1913(see above),
7. turned off and placed both SIM in the tray and rebooted:
Now call, messages and data work on both SIMs.
After that i did install LR TWRP and crDoid and now both SIM work even that they are displayed with Operator UNKNOWN and Number UNKNOWN. Still the calls to 1913 are diverted to 112/911(see above).
Unfortunately the wlan0 in cDroid is not pessent and WIFI and Hotspot are not working.
So I did install the CUSTOM xiaomi.eu Rom (11.0.9,curtana) and here both SIMs work and the Hotspot
I hope this helps
