Hi to all,
I've a problem with my Samsung Wave + my SIM (Vodafone).
I'm unable to register SIM in UMTS network of my operator but I can register correctly SIM in GSM network.
In service menu (#*197328640#) in idle SIM shows LIMITED SERVICE as message.
On NAS status it seems that PS attach is rejected with cause 0x6f.
My operator has tried to reset my SIM and substitute it with another but without success.
Problem is independent of cell. My SIM in another phone registers correctly in UMTS and in my phone another SIM of my operator works correctly.
It seems that only the combination of my phone (IMEI?) + my SIM (IMSI?) is unable to attach on UMTS network.
Phone is NOT SIM/Operator locked.
I've done a full reset of EEPROM (*2767*3585#) without success.
I've also reflashed with multiloader AMSS and other parts of fw related to WCDMA and RF, but still the same problem.
Integrity and Ciphering in service menu are [ON] so I exclude problem related to them.
I've started inspecting phone with QPST and RevSkills but I don't know NVItem mapping of Wave.
Someone had a similar problem and has found a solution?
TIA

Anyone knows?
Thx.
Hello all
I'm using a Redmi Note 8 pro with the latest Android 10 update.
I was having network issues so I entered into test mode and just ran ping test a couple of times.
Then the page said that in order to change the settings you must reboot and I did. After that my phone stopped showing the second SIM card.
I went to test mode again but phone information 2 was missing.
I checked my IMEI number from the dialer by entering *#06#
I can see only one IMEI number being displayed, the IMEI number of the second SIM slot is missing.
I tried to input it manually using MTK Enginner mode but the CDS information option under connectivity settings is missing.
I've not rooted the phone or ever unlocked the bootloader
Below are a few screenshots.
I'm in a very terrible condition as service centres near me are all closed due to Covid 19 lockdown
Can anyone help me out regarding this problem and tell me a fix ???

A factory data reset did the job and the phone now shows both SIM cards.
Everything running perfect now

Swapped sim slots sounds like what happens when downgrading to Oreo. The fix for that is to use a newer (pie) modem partition.
https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350
I see a more recent thread complaining that sim 2 does not work. I only use sim 1 and it works for me.
Did you try turning the phone off (not just sleep or reboot)? My data connection almost always dies when I install an OTA (probably TWRP). Turning the phone off and sometimes leaving it in airplane mode for an hour fixes it.
In my case, the network is rejecting data connections (call and sms works). This was not in the regular logcat...
adb logcat -b radio
