[Q] no unlock code prompt when adding sim?

Is there a way put in the unlock code without a new SIM? I went from Tmobile (HTC ONE) to straight talk on compatible tmobile SIM….it never asked for unlock code. Put in new APNs but can not remove preset Tmobile APNs (2). Phone and MMS works, but not email/internet.
I don't think you have to unlock it with that kind of SIM card internet not working don't know about that

[Q] K910 DUP WLAN & BLUETOOTH mac

Long story short, I have 2 of the Lenovo Vibe Z K910 dual sims phones. One got bricked while doing a update to a custom ROM. I was able to recover, but SIM1 slot wasn't working correctly. It would recognize the SIM card but seconds after booting it would go into "No service" state. So, using the QPST Software Download tool I did a backup of the working phones QCN info & restored it to the phone with the issue. Both SIMs worked!! But the IMEI for SIM1 slot & the mac addresses for WLAN & bluetooth are the same on both phones. I was able to use RF NV Manager to edit the QCN file with the correct IMEI info save it & restore to the phone. Now I just have DUP mac address for WLAN & bluetooth. I can do a "Restore QCN" via the Lenovo recovery menu, that gets the correct MACs but then the SIM1 slot doesn't work right again. I've looked through the QCN file with RF NV Manager to try to find it but must be missing it. Anyone know where in the QCN file I can edit the MACs? Or any other way to correct the MACs.
Thanks in advance

Dual SIM phone with SEEK patched android

I'm new here so please bear with me.
long story short, I'm in need of a dual-SIM NFC phone that I can build a SEEK patched android for it.
So far I've done the patching for GS3, mostly with the help of usmile blog, then since we can't put our applet in real SIM card, made a fake UICC from a java card so that it was recognized by phone RIL driver (`libsec-ril.so`) as a valid SIM and granted access to it.
So till now, there is a phone (GS3) that we can put our java card in it and exchange APDUs. next goal is to do the same for a dual SIM so that it can have a real SIM and a java card simultaneously.
what follows is my questions:
1. Is there any successful android build for dual-SIM NFC phone? (maybe from cyanogenmod ?)
2. If there is not, is it possible to do so e.g. for Xperia E3 dual or GS3 Neo?
3. What should be done to make Android work on a dual SIM phone?
Thanks

Set IMEI numbers manual

Hello,
after reflashing from android to ubuntu touch, the sim cards were unable to register to the network. Searching I noticed that IMEI numbers were not set. In android there is the engineer mode where someone can set these by getting there.
Is there any way to do it in ubuntu touch, even if I have to edit system files?
thank you.
We are not able to give you information on how to restore IMEI numbers to a handset, as it can be used for nefarious purposes. At least, that was the explanation that I've seen a lot.

Help with build.prop - no SIM recognized

Hello,
so I have a problem with a Huawei P10 Lite. Basically I had a fully functional build of this ROM (https://forum.xda-developers.com/p8...m-lineageos-14-1-huawei-p8-lite-2017-t3649292) that I had prepared for my new mobile contract. Everything was working fine but when I put my new card in, nothing I could do would get the phone to recognize that a SIM card was in my phone. My card works fine in other phones, I tried other cards and multiple cards in my phone (while enabling the dual SIM option) and all combinations of SIM slot 1 or 2.
Someone recommended that I edit my build.prop file with:
ro.config.client_number=1
ro.config.modem_number=1
My build.prop has no lines of code like this, I have attached it as well. If someone could tell me where I am supposed to add this code, I would be very grateful.
Thank you.
