Hi,
a few days ago, my Mi Mix 2S started to fail connecting the mobile network for phone & data. I had two SIM cards and every few minutes, I get a notificaton on SIM card change, asking me to choose which one to use for data.
I removed one of the SIM cards and tried using only one card in either of the two slots. Whatever I do, after a few minutes, the mobile connection goes down. I can enable and disable airline mode to force a new connection, and typically, I will get connected again for a few minutes, before it goes down again. This happens on both cards, so I don't think the issue is in the card.
Any ideas? What else could I try?

Problem is the following: So far this has not happened but today it happened 4-5 times already, the phone just freeze and not respond to commands, the screen turns black as when it goes off, but do not goes off, after 10-15sec being turned on and the icons appear, but 2-3 times disappear. This happened mainly when the phone is idle and when I try to unlock it, and once when I used it. When this occurs the signal indicator disappear and show a crossed circle, and what interested me most and I can not reveal what, I get a white triangle on the top left corner with an ! mark. What would that character is supposed to, since it disappears when the phone is stabilized.
That white triangle appears when there is no SIM card inserted into the handset.
It seems you have a faulty SIM card or faulty SIM card slot. The freezing up of the handset could be because of the same as the white triangle appears when the handset freezes. Here's what you can do:
- Try to use the handset without the SIM card for a hour or so & check if it freezes again, if it doesn't then the it's a SIM related problem.
- Use a different SIM card & check how it goes.
Hope this helps.

Hi there!
So i got a NEXUS 5 32GB.
Short story: i had an old SIM card, like 5-10 year old, when i bought the phone. I cut the card into microsim, and worked like a charm. (You know, nexus stuff when no service sometimes like once in a week (restart solved always the problem)). Now i contracted with a new service provider, and the (3in1) micro sim i get is unreadable to the phone.
Detials:
-The new card working in other phones without problem.
-I went to my carrier and get a new sim card, doesnt work either. (so the sim card(s) not defected)
-Tried different SIM cards in my phone-> working only the old SIM cards, new micro sims doesnt
-Tried almost every softwere stuff, (factory reset, FR in recovery mode, flashing 4.4 android, flashing other androids, flashed radio files etc.etc) ->non of them worked.
-We disassembled the phone, the sim reader is looking perfect, not a scratch, all pins in order etc.
-THE MAIN problem: however i insert the new card(s), phone says only "No sim card, emergency call only". Can't even set up the mobile services, nothing. Only can turn on-off the NFC, Airplane mode etc.
-When inserting the old cutted card, works perfectly.
I'm paying now for 2month for the new card, but can't use it....
Please help me!!!
Any kind of help will be appreciated.
Thank you very much.
Have a nice day.
PS.: Sorry for my english, i'm from Hungary.

Hello everybody,
I experience a quite annoying misbehaviour of my S7 Duos: For three days now, when I have a second SIM card in use, the wifi is disabled and wont turn on whatsover (tried anything, from stop&restart data, bluetooth, up to factory reset). Has anybody experienced something similar?
Wifi would work with no SIM, SIM 1 in use, SD alone in use or SIM 1 & SD in use. But not with both SIM slots or 2nd SIM slot in use, regardless of SIM card (I've checked with several SIM cards, it's the slot not the card).
Please give me a hint.
Thank you!
I have Oneplus 8T with Android 13.
My SIM was on Slot 2 yesterday. Then I accidentally clicked on "Disable SIM".
Now it says "No eSIM" "Disable eSIM to u.." (it only shows second line partially) when I insert it in Slot 2.
When I insert it in Slot 1, it says "No SIM card detected".
Note:
1. If I use any other SIM, it works on either slots.
2. When I this SIM on other android phones or even a feature phone, it works correctly without any issue whatsoever.
3. I've already tried the "Reset Network Settings" feature. Ideally I don't want to reset my phone completely
Have the same issue too, can't figure out any way to fix other than getting them to send out a new SIM card each time...
Anyone else have any other ideas?
(Edit, just realised this is on a 8T forum, mines a 9 Pro... seems to affect lots of OP devices)
I factory reset the device - SIM starts working immediately. Disable SIM 1 and the phone instantly forgets it again...
Back to wiping it all over again. Thought I'd rather test it now before I set it all up

So. This seem to be a rare but still unresolved problem effecting users on all brands of phones using eSIM.me sim cards. Google does not turn up much other than the typical 5-9 steps including re-seating your card, restarting your phone and...
