Really strange case:
I got a RAZR M that I hacked to work with US GSM carriers using this method: http://forum.xda-developers.com/showthread.php?t=2166542
I am using my corporate ATnT card with it.
I am currently in roaming (Russia first, now Kazakhstan). Only GSM/UMTS networks here.
I have another simcard with me which is from Russian operator (Beeline). This network is present in Kazakhstan, however simcard is Russian, so in Kazakhstan this Beeline simcard is also in roaming.
Status:
On ATnT card, my RAZR wont connect properly to local cellphone networks. To explain better - it will occasionally connect to one of local operators (KCELL, MCC/MNC 40102), but it takes A LONG time to connect, easily disconnects, and it is very unreliable and erratic.
Moreover, in Mobile Network Settings menu there is NO OPTION to select operator (i do have GSM/UMTS mode enabled, not global).
On BeeLine card, my RAZR happily connects to any of chosen networks, AND operator selection option is available in Mobile Network settings.
I have another phone in my pocket - old Nokia S40 based. This one works perfectly with Beeline simcard. With ATnT simcard it wont automatically connect to a network, but manual operator selection dialog is accessible, and I can select any network and connect to it.
So, for some reason, with ATnT simcard in my RAZR, mobile networks settings menu disbles (completely removes!) operator selection dialog.
Any way to get around this? I have scraped around every possible search criteria, but I cant find any way to force that menu item to appear!
However, I accidentally stumbled upon a weird workaround:
I put Beeline card in
Manually select operator (Beeline)
Turn off the phone
Put in ATnT simcard
Turn the phone on
In this case on startup phone throws in notification (from motorola phone app) saying "selected preferred network not available".
If i click that notification, it takes me directly to network scanning menu, happily displays available networks and allows me to connect. From that point on, it stays fixed to the network I chose.
This means that this is not a problem of simcard or radio or ROM directly. It is some weird trigger built into ROM that reacts to ATnT simcard and removes "operator selection" option from setting.
Any idea how to force Operator Selection option to appear, or invoke it otherwise? Or maybe solve the issue alltogether? My workaround is really inconvenient.
There is also software based bug for network mode. I have personally experienced this i.e. network mode doesn’t change in reality even if I select 3g mode. So, to force your particular sim card to switch to 3g only mode, first deactivate/disable other sim card on Yureka from setting> sim cards menu. Then dial *#*#4636#*#* > phone information. Tap on Turn off radio button and wait until the button reads turn on radio. Select WCDMA only from dropdown menu above the button. Wait a few seconds. Now tap on Turn on Radio button. Your desired sim card will successfully connect to 3G network. Now go to settings and sim card option and activate the disabled sim card as well. You may need to manually search for network signal if no network is shown. Also you may need to restart the device. If in 3g mode, your phone doesn’t connect to internet, Go to apn setting to ensure correct apn is selected. Sometimes APN menu might not show any installed network settings, in such case, just restart the handset. All these network related issues will be hopefully solved in the next Yureka ota software/firmware update.
after you did this you need to reboot your device......

In my yureka mobile, Sim 1 is suddenly getting disconnected and not detected. I tried to swap the sims then again the problem persist with same sim but not the sim1 slot. I am using the mobile with same sim cards from more than 20 months. But this peculiar issue started occurring from last week. Again the sim is getting detected only after restarting the mobile. I am facing this issue more than 10 times a day. Can you please provide me the resolution.

Hi all,
On a Honor or Oneplus, you can switch the mobile data from sim1 to sim2 and the 3G/4G switch also... But on the Xperia Z5 the SIM is ONLY 2G !!! There is a tweak or idea for switching without change the SIM card slot
Sounds like you just need to select your data SIM slot as the 4G one.
From the manual:
Selecting a SIM card for data traffic
Either of the two SIM cards inserted in your device can handle data traffic, but only
one SIM card can be selected to handle data at any given time. You can select the
SIM card to use for data traffic during the initial setup of your device, or you can
select or change it later via the Settings menu.
To change the SIM card used for data traffic
1 From your Home screen, tap
2 Find and tap Settings > Dual SIM settings > SIM card for data traffic
3 Select the SIM card that you want to use for data traffic, then tap OK to confirm.
For higher data speeds, select the SIM card that supports the fastest mobile network, for
example, 3G or LTE.
Selecting mobile networks
Your device supports the use of two different networks at the same time. You can
select from the following network mode combinations when two SIM cards are
inserted in your device:
- One LTE network and one GSM network
- One WCDMA network and one GSM network
- Two GSM networks
For each SIM card, you can set your device to switch automatically between mobile
networks depending on which mobile networks are available where you are. You can
also manually set your device to use a particular mobile network mode for each SIM
card, for example, WCDMA or GSM.
Different status icons are displayed in the status bar depending on the type or mode
of network that you are connected to.

You Can switch networks without changing the sim cards, it's in "mobile network settings".
Thank Reza !!

You have true but when you switch the data to the SIM2, it's only 2G

No, just tested that. Maybe your second sim card doesn't have 3G/4G coverage.
good afternoon.
I have this inconvenience.
I have two phones exactly the same xt1609.
The first phone was unlocked and converted to GSM and works 100%.
base band (M8916_20250106.08.05.23R HARPIA_NA_CUST)
the second phone was unlocked but I could not make it work.
base band (M8916_20250106.08.05.23R DFLT_FSG)
There is a difference in the second team. when having the equipment without sim card the base band is (M8916_20250106.08.05.23R DFLT_FSG) but when putting it sim card it is changed to (M8916_20250106.08.05.23.01B DFLT_FSG).
When trying to search for networks, it generates an error message in activated airplane mode.
someone could help me thanks.
