Hi
Whenever I'm out of Wifi-range, and want to connect via UMTS/edge nothing happens, even though its enabled as far as I know. If i go into settings -> about phone -> status and look under "Mobile network type", it says UMTS. But then further down under "Mobile network state" is says disconnected. How do i turn this on then?
Did you unlock your phone? Check your apn settings you will need to change them to your specific carrier in denmark.
Thanks! Found my carriers apn and now it works! Im still a bit of an android virgin im used to Steve Jobs and his fruit-loving staff deciding for me
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.
i have bought samsung galaxy s5 (SCL23 by au /SM-G900J) from Japan.i have used that handset in bangladesh with Grameen phone network (GSM). After using 8 day the handset took automatic update via wi-fi. And after taking restart... the network was gone. Now its showing out of service sign instead of network. But sim menu is available in menu. When i wants to use settings>more network>mobile network..handset shows "insert sim card to access network services". Out going and incoming call is off. I can't use mobile data. Now what can i do to recover the network? pls help me.......thanks in advance...
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......

Hi
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.

I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks
I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
