Why can't Nubian mobile phone receive verification code information?

It depends on what model Nubia is. Is it dual card dual standby? This is very important! ! !

Tell me about my solution. First of all, I have a Nubian z 1 1mini. I have bought it for more than two years, and it has been used as a backup machine, which is also quite good.

Recently, I found that I suddenly couldn't receive some APP// website/community registration verification codes, and my mobile phone couldn't play.

1, I put the card in my Apple phone, and it is normal to receive it, which means it is not the card.

2. No security software is installed, and the only one is the mobile phone housekeeper that comes with the system. I can't see any harassment interception function, and I can't uninstall it, so I also gave up the operation.

3. The mobile phone is backed up, so there is basically no function setting, so the elimination is a misoperation.

I restored the factory settings once, and it was fine for about a week, but it didn't work.

Later, I couldn't call the customer service number or find the after-sales outlets. It suddenly occurred to me whether it was the reason of dual card dual standby, so I changed the position of two cards. Card 1 is for telecom and Card 2 is mobile. That's good!

I suggest that friends who have the same problem can try it.
