hi!
i'm facing a weird problem with dual sim network. sim 1 or sim 2 whichever is assigned with 2g/3g/4g option gets cellular network only and the remaining one shows 'emergency calls only'. assuming that this is an software issue, i've changed the rom using HiSuite; but the problem yet prevails! the phone was okay for last around a year and this issue just happened couple of days back...
is there any solution/suggestion to get rid of the problem? thanks in advance!

factory reset or reinstall rom.
While it might be ROM/firmware issue, another possibility is the cellular frequency bands. Whichever SIM is assigned as data sim (2/3/4g), the other SIM can only be (2g). It might be that the telco has discontinued 2g frequency band.
I have similar issue on Honor 8 which I think has the same limitation (only 1 data SIM). If I assign SIM A as data SIM, SIM B would lost signal; but SIM A has signal if SIM B is set as data SIM. This is regardless of the SIM card slot. In my case, probably SIM A (its telco) supports 2g band, but not SIM B.
I have just got a used Cubot H1 which has a dual sim slot.When I have a sim in slot 1 and go into phone info it appears to be connected as it shows signal strength and service state as in service but will not send/receive texts/calls.Slot 2 works and shows the same info .I have swapped sims over and although the phone sees both sims and shows the same connection status slot 1 still does not work.
Is there something that I need to set up?
Phone is unlocked .
Thanks
I have an unlocked Lenovo Golden Warrior Note 8/A936 2 gb ram dual sim phone. Its also rooted. In my country there are 2 network providers. I have a SIM for both. The phone recognizes both of the sim cards and even labels them by their network name but only picks up the service for one of the network providers. Ive made sure both sims are good. They both work fine in my Samsung Galaxy Note 4. Trying to figure out what could be wrong with the Lenovo as it won't pick up any service for that SIM card.
Ive tried:
both sim slots and still only one recognized.
removing the working one and the other still wont find service
Factory resetting
Manually/Automatically finding the network. Manual search doesnt find the ine i want to find
Switching from 2g,3g,4g preferred types
Any idea what could be wrong?
wrong lte/4g channel
Maybe your provider uses a for the handy not usable channel and the sim is a lte/4g only! So the device doesn'T recognize the sim, Iguess. I'm sorry, bad luck
Hey guys I'm miui lover and want to use miui
Now a days many devs like epic ,turk and etc have patch miui for 7.0 and all say volte is fixed but for it volte is the only problem that stopping me for using them
I have sticked my sd card to volte sim so I'm force to use volte on second sim now when i tried all of them week ago none of them work volte on second sim
My problem is that
1-when i put only one sim in second volte work
2- when i put 2 sim volte on one and normal on second volte work (my brother sim)
3 but when i put normal sim on 1 and volte on second it doesn't work
4 but if i put 2 sim only volte and switch phone volte work then add 1 sim with phone on volte work perfectly on second sim for days even but after i restrt it stops working
Plszz help me what should i do
I have recently changed mobile operator. During the transition I briefly needed to use two SIMs while my number was ported.
After some struggles, I managed to switch the 4g over to SIM 2 but I can't remember exactly how I achieved this. Now that the number is ported I only want to use one SIM in slot 1, so that I can use an sd card. However I am struggling to activate the data connection in this slot. APN settings are identical.
In summary, data connection is only active when the SIM is in slot 2 (nano/hybrid slot) but not active in slot 1 (micro SIM). How do I fix this?
