Can any one tell me why my TAB will not recogize my valid, working SIM card from my other phone? Perhaps some setting on the TAB has to be changed?
Thanks for any info.
dude
dude i dont know. i tried the same thing. i have tmobile usa and the Galaxy Tab, along with my HTC HD2. tried the swap, no dice. saw my phone number, but would not txt, call, or receive calls. no data either.
My TAB doesn't even recognize when that the SIM is plugged in .
It keeps saying: "Please insert a SIM card". "Emergecy Calls Only".
This is going to sound really dumb but try shoving the SIM card in further. With certain brands of SIM you can get a "click" without the SIM being correctly seated in the tab. The tab will reboot if you insert a sim properly while it is on.
Problem solved! I thought that it was unlocked, but it wasn't. Followed Rothammer advise on unlocking and that worked like a charm.

I have the same problem with my SIM not being recognized. I have an AT&T Tab; unlocked [verified network is unlocked]; flashed with Rotohammer's most recent JME-Full; Baseband is I9000UGJK3; IMEI is OK; and Mobile Network is HSDPA. Interestingly, the signal strenth shows full bars, but does not recognize SIM and does not allow me to enter the Mobile Networks [grayed out] to change anything. I've tried every fix from every thread I can read here. Any thoughts anyone to get this to use voice and data?
Flash the Bell i900 modem for at&t tabs.

hello i bought one galaxy note 3 (my second one)
i'm having one issue,the first one i bought and i ended up selling had a Bad esn but let me to conect to other networks
such as telcel on mexico,movistar,iusacell and other ones
i bought another one but i don't know why i can't use it on other networks
i tried with the service mode codes but i can't enter to something like the UMTS option on the s4 to turn off the perso sha 256
also i tried installing again the firmware with odin and it continues without signal
when it starts it shows some "sim icon" notification on the status bar and says "phone activation" the sim card is from an unknow source
it 's didn't surprise since i know the verizon phones come GSM unlocked.
maybe if someone knows other form to flash the firmware could help.
i read about some galaxy devices loosing the imei after one update ,if i dial *#06# it shows my device .
if i go to settings and mobile networks and try to select the network(telcel) i won't let me register on the network.
i hope everyone have a nice day and maybe someone could help me.
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...
Hey guys. I purchased a samsung galaxy s8 off craigslist. The Imei number is clean and clear, Ive checked on several websites BUT the sites can not detect WHICH device it is. However, when I throw in my tmobile sim card the internet is very slow or does not work at all, and the calls barely go in/out. It Displays 4g LTE but then it disappears sporadically. Do i have an international version? Any thoughts or consultation would be really appreciated.
P.S.the IMEI on the box and phone do not match, but I rang it in to Tmobile and it is clean and clear.
Please help guys much appreciated
Thanks
