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?

Hey all,
This may or may not be ROM specific, but I just switched carriers and for the time that my number was being ported, I had both my old SIM card (Net10 on AT&T towers) and my new SIM card (T-Mobile) in the phone. During that crossover time, everything worked fine. In the SIM settings page, the carrier for each SIM and the associated phone number appeared correctly. However, once I removed my old SIM (phone was powered down any time I changed SIMs) the phone still functions fine for calls, texts, and data, but it no longer recognizes the SIM carrier or phone number.
This is made worse, as the carrier has an app that checks the SIM card before running, now, the app just shows "We do not recognize your SIM card".
I also noticed that carrier specific dialer codes no longer function. For example, if you dial #264# you should be presented with the status of T-Mobiles "Binge On" feature, but now it just does nothing once I hit call.
I have tried swapping the SIM between slot 1 and slot 2, I have also tried rebooting numerous times, all to no avail. I'd really prefer to not have to switch ROMs, but if that ends up being the solution, I guess I'll do it.
Any help would be appricated.
Thanks,
Austin

What does your Settings>About Phone>Sim Status show?
There are some apps (root+Xposed required) which edit the number in the sim. You can also input a number if it is blank in the sim.
Failing this, you may have to approach your service provider.

The Phone Number row shows as Unknown in there as well. However, if I insert my old sim in the other sim slot it then shows my correct phone number.
So the number is there in the sim, but for some reason is only read if I have both sims in.
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

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!
I recently started using a second sim. I am trialling another network so it might be temporary or it might not.
I left my original sim in slot 1 and put the new one in slot 2 and set calls and messages to slot 1 and data to slot 2 as mobile data performance is what I want to test and I do not want to impact people trying to call me. What I noticed when I did this that only the new sim card 2 showed as connected under mobile network state sim card 1 was showing as disconnected.
My expectation was that they should both be connected?
