Can you provide the IMEI number of the phone?
In idle mode enter *#06#, the display should provide the IMEI number.
The display should have two antennas (to represent each SIM)
what is being displayed when the SIM is in each slot?
And is there any error on the phone or just lack of conenction?
I think I can help if you are able to answer those questions
Hi I dont mean to jump on this thread uninvited, however I am experiencing a similar problem. I have a CH@T222 samsung duos and i am experiencing the same problem. I was hoping that dthomps4 could help. I have an international roaming sim and it works great, however, my tmobile sim only shows the red circle with the line (no network).
The IMIE number is 358791 04 297265 /5 and /3.
There are no network errors. Just the red circle of shame. I used the samsung coding to verify that the phone is completely unlocked.
The phone model is GT-E2222. Please help!
Have you been able to change between SIMs through the phone's menu?
My cut and paste dropped the images, but if you have been there it would make sense
In Idle mode, press [ ] to switch between networks.
To activate SIM cards
1. In Idle mode, press and hold [ ].
2. Select Network and scroll left or right to a SIM card.
3. Press <Change> to activate the card.
I have never used one so my questions will be mostly to discover what the device can/cannot do and the menus available.
Is there any form of network selection on the device?
I know some devices must be set to work on 1900 networks, otherwise they remain looking for European netowrks, is there anything like that in the menus?
Trying to find an online manual
Found something interesting!
Ona german Samsnung site they state
"One of the two SIM cards can be used to make phone calls on GSM networks of 850, 900, 1,800 and 1,900 MHz, the second SIM card just in GSM networks of 900 and 1,800 MHz."
so I would move you T-Mobile SIM card into the other slot and see what happens
