and wanted to ask, if it is possible to have as I understand reading this

amss_fsg_maple_hutch_uk_volte_vowifi_tar.mbn flashed onto the G8142 - dual SIM version to get access to Band 20?

first you must confirm your phone card slot are dual sim card slot ,you can buy a dual sim version card slot and put it in your single sim version,i have tested ,my xzp is single sim card but i
found it sd card slot is a dual purpose card slot. i recommend you flash oreo dual sim version firmware and unlock your phone,root. modified the system build.prop ,find "persist.radio.apm_sim_not_pwdn=1" change the"1"to"0",restart your phone and dual sim will work with SDcard together

Hi @7evenfone
As this thread suggest,
https://forum.xda-developers.com/xperia-xz/how-to/dual-sim-sd-card-one-t3475651
it does not work .... You can not use 2 SIM cards and SD card together ....
Anyway, my question is about using my dual G8142 with 2 SIM cards (3UK Slot1 and VodafoneCZ Slot2) "no SD Card" on Band 20 = 800Mhz network with my 3UK SIM and therefore being able to make VoLTE calls and possibly Wi-Fi calling instead of their ThreeIn Touch app that sucks ...

The sim does not recognize the mobile
Do you require international decoded
When you run the mobile without sim show me this letter :
"A sim card is needed to operate this phone. please turn off your phoneand insert your sim card"
I hope help.

How can i check whether my sim card is 64k pr not??? The reason i m asking this is that I m planning to flash a custom ROM in my Micromax A110 and many users are complaining that there old sim cards are not working whereas 64k sim cards are working. So i want to check whether my sim card is 64k or not. I have already checked the sim card. Its not written anywhere on the sim
Two days ago the SIM card slot (both) didn't work.
Both slots (gsm and gsm + WCDMA) can't read any type of sim (different company)
I would like know if is possible use ADB for check/scan if SIM card reader works
I didn't found any hardware's damage on it.
So , the problem is probably in the software
I hope in your help
Regards

its probably a corrupted NVRAM (unknown / null baseband or IMEI). You might wanna read this piece on how to fix unknown Baseband version, null / invalid IMEI & SIM card not detected to fix this SIM card detection issue
Hello! I just ordered this phone and I'm having a little trouble using the 2nd SIM card slot. I would like to use a MicroSD card in SIM slot 1. The SIM card works in slot 1, but when I put it in slot 2, the phone does not read it.
I'm using it on T-Mobile in the United States. Any help is greatly appreciated. Thank you.
Hi!!
Does anyone know where I can find the mode that will allow me to have both the sim card slot and sd card active with a sim adapter simultaneously? I'm not ready to go with a custom ROM yet, as I want to play with my stock & rooted Note 20 Ultra N986B/DS Exynos. I had the 2 sim + memory card mod on my S8+ and loved it. Any help would be greatly appreciated.
Thanks!!
