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)

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.

Hello all, i have Samsung a7 2017 and i am on stock firmware and not rooted. I am having network signal problems at some places in my house. I removed my sim card and put it in other phone and the other phone have full strength network. On my Samsung A7 2017 when running USSD it sometimes it is saying "Not registered on Network". I tried flashing other modems and roms but still not good. My IMEI is clean. This problem appeared after Nougat update. I am from MAURITIUS. If anyone can suggest me a firmware close to my country because samsung has still not released firmware for MAURITIUS.
Can you please help me??

Samsung is knwon for bad carrier reception particularly in a and j serier
Settings, then Connections, then Mobile networks.
Is the network type is locked to 2G(GSM) or 3G(UMTS/WCDMA) or 4G(LTE) only (RAT lock)? Set it to auto.
Network operators, then Search networks, then select your network name or PLMNID?
WCDMA / LTE bands were disabled in the RIL service mode?
Did the mobile network operator make any changes, is the tower down for maintenance? Check signal strength and quality with *#0011#. RSSI is strength, RSCP and RSRP is mixed, ec/io RSRQ SINR is quality.
Maybe the other phone decoded the signal of another mobile network operator and displayed full strength? maybe the signal/bars are calculated differently? maybe the other device supports more bands/frequencies used by the MNO?
When I'm using 4g Internet services on my sim1, my sim2 is on 3g by default.. Everytime I'm manually choosing 2g but it's getting back to 3g after sometime.. So how to set secondary sim to 2g and stop it from getting into 3g on H8P mobile??
