Dual SIM issue - Xiaomi Mi A2 Lite Questions & Answers

Hi, I have a A4 lite with latest patches febraury) installed.
since 2 weeks I have a second sim card and it worked fine until a few weeks ago.
my setup is
voice and text message sim1
Data Sim 2
since a few days I'm not reachable on sim1 but on sim 2, only if I switch data to sim1 too, I'm reachable again on my mobilenumber.
I changed the simcard already and got a new one from provider but this did not help.
However I recognized when I switch sim1 to only 3g not 4g it works.
so what could be the issue, and do you think it is a provider ot HW issue?
thanks in advance

SIM2 Not Working

Hi all,
Just got my Zenfone 2 yesterday and was super stoked, however the SIM2 component is not working. I have two SIM cards, one with Telus and one with Virgin Mobile. (Canadian carriers). No matter which order I put them in, the SIM2 card never works. The Zenfone 2 is able to identify the phone number associated with the SIM card in the SIM2 slot, but it is unable to actually make a network connection.
Anyone know how to get SIM2 working?
just update to the latest rom... I did and got my Sim1 working again!!

SIM2 is 2g only. So it needs to be Rogers (or network that uses Rogers) to work

Only SIM card slot 1 can access 3G/4G/LTE data. SIM card slot 2 can only be used for 2G service which include voice and basic text messaging (Not multimedia messaging services MMS or internet browsing). http://www.asus.com/us/Phones/ZenFone_2_ZE551ML/HelpDesk_knowledge/

I know this is an old thread but i was wondering if anyone has found a solution to this issue? I am having the same issue trying to get Sim2 to recognize a network. The number on the Sim card is recognized. I have tried switching the cards around and the result is always the same. Both providers that I am with are in Canada. One sim is with Bell and the second is with Virgin Mobile.
Are you saying you can't even make calls on sim2?

WP 10 and Dual Sim - trouble with Data in Slot 1

Hello,
I figuerd out a curiousity with WP10 and Dual Sim phones. I have a Lumia 640 and 2 Lumia 950 here. One L950 has a SIM Card from Vodafone and run perfect in SIM Slot 1. Data work fine when Wlan is of from 2G to LTE as it should be. In the L640 and the other L950 I use SIM Cards from Provider Telekom / Congstar (which is also Telekom and use same network). Both phones are not able to provide any Data connection when the SIM card is in Slot one while both connect imeditaly once I move the SIM card in Slot 2
I won't care at all to use Slot 2 instead of Slot one but all contacts are without SIM card then and you have to switch all manualy to SIM 2 which is anoying. I verify that I use the exact same settings on Slot 1 and Slot 2 and I also switch back the card but again no Data in Slot. I already find some user with simmilar Problem but nobody had a better solution then to switch to Slot 2. Does anyone here run into simmilar trouble and / or have an idea how to fix that bug?
which sim did you choose for the data connection? 1 or 2
I select 1 once I had the sim in slot1 and 2 when the sim was in slot2. However, with the latest update on fastring it is fixed on the lumia 640 and it has now data in slot 1 as it should be. Unfortunatly the 950 dont take the update. I read that a factory reset can fix it !?
I was traveling recently to Poland and had that exact issue. Polish SIM in SIM1 slot, my homeland SIM in SIM2 and I had issues with getting a data connection. Swapped the PL SIM to SIM2 and it worked.
Issue now resolved with the latest update. Why don't you just enrol your 950 into the slow ring and get the updates?

Dual SIM Issue

Hello there,
Im getting trouble to get the dual sim working properly.
First of all my setup : OOS 3.2.7, rooted, some xposed modules, nothing fancy. Stock kernel
SIM1: Data SIM, o2 germany
SIM2: Just used to receive some texts, all APNs deleted, Carrier : Orange/Sosh France
In normal usage SIM1 is deactivated. In this case everything works flawlessly.
As soon as I activate SIM2 i run into trouble. I loose data on SIM1 almost instantly and the only way to recover it is usually a reboot.
When i loose data the "LTE"/"H"/"3g"/whatever icon disappears, data is still on in the settings.
I noticed that at least once both sims were connected on UMTS when it occured.
Any clue to keep my data connection working when both sim cards are active?
Thank you in advance

Network not working suddenly

Hi, I'm facing a serious problem with my Redmi Note 9 pro max. Suddenly the SIM cards are not detected (Both sims). Sometimes i get only 2g network in my 1st SIM. I have a Airtel sim on SIM 1 and JIO on SIM2. I tried using other sim cards as well but nothing seems to help. It just happened suddenly. The phone is brand new. I can't flash using flash tool because it needs sim card to send some info in developer options. I need help!

Cannot send or recieve SMS from JIO SIM (An indian carrier with LTE only network).

Hi everyone I was using LineageOS 17.1
I have 2 sim cards: One from JIO, a 4g only carrier and another from Vi (Vodafone) which has 2G/3G/4G. I flashed Lineageos first more than a year ago and everything was fine. But sometime around april this year SMS stopped working just for the JIO sim. Calling and Data work fine. I am not sure but i think I updated(17.1 -> 17.1) before this happened. Today i finally decided to investigate this. I tried the JIO SIM on another android phone as well as an iPhone and it works fine. but on my OP3T, it refuses to receive or send SMS. The Vi SIM doesn't seem to have any issues.
Another interesting sidenote is that if i remove the sim from the iPhone and put it in the OP3T, it doesn't work until i reboot the OP3T!
I tried updating to 18.1 today. It didn't solve the Issue. So currently I am on 18.1
Can someone help me figure out what the problem is?
