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

my friend bought me CAT B15 from US,(i live in Indonesia).when i use my cat B15 i realize that the phone cannot connect to 3G, because when i use the same SIM card to another android it can connect to 3G. and the dual SIM card cannot work too.i checked in setting menu, ther is no option for dual SIM card and for 3G.the contact support ask me to send it back to the distributor, but i think it's not make sense. it's so far away from indonesia.anybody can help me?
Same problem here. When mobile data is switched on, no matter which card is in which space, phone tells me I have inserted SIM card in wrong slot and the connection speed will be limited.
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 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
Hi
I have issue while having both sims activated.
Mostly the main Sim card slot sim loses signals and sometime it's not connecting mobile data. I have to restart my phone in such situations.
If only one sim used at a time, then everything is fine.
Does anyone know the problem or the situation.
Hi there,I had a problem makes me quiet confused. Recently I did buy previously used galaxy s7 edge.The phone come to me as new condition.First I notice missing label on the box where is says serial number,imei,bar code etc...Only other label on the box says europien sim only.Switch on the phone and everything seems to be ok,until I did not put in my sim card. Phone did recognize sim card and network provider but was unable to connect to network.Try with few more sim cards from different country's and network provider but the result was the same.Here comes the funny part.In the phone settings>about the phone there is a serial number and imei number.Both numbers don't match the type of the phone.Even the imei number.On the internet under this imei I find completely different phone.Model of this phone shows as 935fd.This sopostu be a dual sim but it's not.I do have this option for the second sim inside the phones settings but there is no way how to put the second sim in to the phone.Only one sim fit there and one memory card.Root count one.Previous owner maybe somehow manage to flash different model software,or something.What I will like to know if there is a way to fix it.Bring back the phone to it's original condition so I can used for the phone calls also.Thakns for any future respond.Hopefully I make my self clear about the issue I got
