Hello all. Haomi Redmi Note 4 Snapdragon 625 MIUI Global 8 Smartphone.2. Came from Aliexpress. I put the first SIM of Megafon, turned on there is a network Megafon. I put the second SIM Beeline, turned on no signal, no MegaFon or Beeline. I take out the SIM Beeline, but Megaphone still no signal. What could be the reason?

Translate to English, set up an account, connect the account to the numbers and activate the SIM

Hello, smartphone Xiaomi Redmi 4x, put two SIM-cards, one sees the second does not, sim card works

Hello, I also have one sees and the other does not, and also Xiaomi Redmi 4x.

If the tray for the SIM-card is not whole (for example, chipped part of the plastic or bent metal plate), this can be the cause of the problem, when Xiaomi smartphone does not see the SIM-card. I had exactly the same situation on the Mi 3. The service center could not find the cause of the problem, I found it myself. I hope this helps someone.

The problem is network and does not receive calls and SMS Xiaomi Redmi 4x 2/16gb MUIU Global9.1 stable

How to implement the items from the list: Do not press unnecessary?, If there is NO SIM card in the settings? And there is a SIM card in the tray)) Why are these items written, if they are useless?

Hello!It seems that the phone has already ruined two sim cards! Model Redmi Note 4x, 32g Stopped recording in the network sim in the 2nd slot, thought the problem with the phone, but when you install the sim card in another phone, nothing has changed!Checked it = damaged card! I took a new SIM card, installed in the second slot Note 4x, all repeated.The network appeared for 1 second and then disappeared, the SIM card stopped working even when installed in other phones!I’m afraid to put anything in the second slot. The first SIM was a promotion, with free internet. an irreplaceable loss(((If the reason turns out to be in the phone, I have to abandon the company. The question is whether the phone could burn the two sim cards.

I support the same phone, the same thing. Phone is one year old, suddenly the SIM card fails. I change, it works for 3 hours and the same thing. Beeline checked, reloaded the card, nothing helps. The SIM does not work in other phones after the breakage. But in the evening, sometimes there is a network icon without operator identification, and SMS come from undialed When attempting to call from the phone immediately icon is inactive and says no mobile network or when the icon is, but the network name is not defined when you press call trying to connect, after about 30 seconds says call completed. Such things.

It is better to use Samsung. For the first time, I took Xiaomi 5 and then the calendar can not open, then he deletes contacts. Now it does not see the SIM card in both slots.
