I am not able to switch from my 3G to 2G on my motorola defy. I have a vodafone sim activated 3G on it. 3G working fine. I also hv another Airtel sim. 3G is not activated on that sim. When i use that sim 2G also works fine. But i want to use 2G on vodafone. when tick "USE ONLY 2G"
from the setting, the whole network dissapears.. I am having this problem since CM9 latest built. Currently using CM10 2/08
Please help me
I want to buy the I9192 and i wanted to know if it supports 2 sims that work only on 3g networks?
Or the second sim slot is only 2g?
Thanks!
Both the sim slots can be used for 3g reception.. but only one sim can be 3g at one tym.. i.e either sim 1 or sim 2 can be 3g at any given time...
by 3g you mean that i can use data only from 1 sim?
I have 2 sims from a networks that uses HSDPA 850 / 2100 - would both of the sims will work at the same time? (I don't need data on both of them, only on 1 sim, but i need reception for calls & sms on both sims)
Will it work?
Thanks!
Yes. Only one sim will be used for the data connection.

yes, both sim cards can recieve calls/sms at any given point,
but for data, only one sim: either sim 1 or sim 2 ( whichever is choosen by you)
your answer!

I made all possible tests, it will only work 3g or hsdpa data speeds on slot 1. if you switch your data service network from SIM1 to SIM2 it will only work 2G, if you go back to SIM1 you will have 3G normally again.
hope this helps. BTW, in the Manual or user guide for this phone this feature is not clearly explained.

I confirm: both sims works on 3g but only one at a same time.
You have to mannually select which sim will use mobile data on settings > my device > sim manager > data service network.
If you choose sim2 for data, sim 1 will automattically switch to 2g network and sim 2 works on 3g.
Make sure your data provider has 3g coverage on your area.

check my post on http://forum.xda-developers.com/showthread.php?t=2490419 for the solution.
Well both work in 3G but only the slot 1 works on HSDPA/HSDPA+ the second slot is locked into GPRS mode and I have experienced this behaviour on 4 rom before knox samsung proctection avoid me to flash my phone as I want.
I hope someone can help to answer the following query as I can't seem to get any information / confirmation on it's dual SIM functionality. As some of you may now, some countries has discontinue in offering 2G connectivity.
On the Honor 8 Pro dual SIM, does it function as ;
A) if SIM1 is selected as default data line on 4g/3g - can SIM2 run simultaneously on 3g (non-data)? Or,
B) if SIM1 is selected as default data line on 4g/3g - will SIM2 run simultaneously on 2g only (non-data)?
Noted they are dual stand-by. My question it's on the band connectivity for the none default data line.
Hope to get some guidance

I strongly think it's B because that's how the network with Honor 8 works.
A) is true! But B) doesn't allow you to be based only on 2g, it switches between 3g 2g
Also if you select mobile data default sim as 2, then it will be switched to 4g network and if your sim 1 is 4g only, it will be withering around with no network

I also facing the same problem.I have 2 sims one Jio and one BSNL.I Jio as SIM1 and BSNL as SIM2.In my area for BSNL both 2g and 3g are available but 3g has less strength.So it switches between 3g ang 2g.My battery drains fastly
I can't call through Airtel network. Robin only shows lte network no 2g. Please help. Tried every ROM and stock also. During call it doesn't change to 2g network it stays on LTE.
4G LTE data works on both sim slots but only 1 at the time and only on the sim slot that i have set as the preferred data slot. Does anyone else have this problem?
When i make or receive a phone call on the secundary sim (not the primary/preferred data sim) i lose data connection. The primairy data sim is then automatically switched off. I have of course the Enhanced LTE toggle switch ON on both cards in network settings but this does not seem to work properly.
When i make or receive a call on the secundary sim the 4G LTE connection stays on for voice but the phone does not switch the data connection to the secondary sim card. The network connection on the primairy card is then also shut off completely. No network signal. So i cannot use internet during a voice call and also cannot receive a incoming voice call on the primairy sim.
Both network icons then show an "X" on the signal bars but strangely i keep the voice connection.
After I hang up the voice call on the secundary sim, the 4G LTE voice and data connection comes back on the primary sim and both signal bars go come back to normal and the "X" dissappears.
When i make or receive a 4G LTE voice call and surf internet at the same time on the primairy sim there is no problem. I have a Volte connection so i can voice call and surf on the internet simultaniously on 4G LTE.
This secondairy sim slot problem was NOT a problem on Android Pie on my Mi A2 lite. On Android 9 I had 4G LTE VOLTE HD voice and data on both cards all the time always. I could receive and pick up calls on both cards at the same time and keep data connection.
After OTA to Android 10 I soon discovered this problem. I did factory reset. I switched the primary sim, switched the sims in the tray. Nothing makes a difference. 4G LTE data works on both sim slots but only 1 at the time and only on the slot that i set as the primary data slot.
Does anyone else have this problem?
