[Q] Network not found when sim card inserted - Galaxy Note 3 Q&A, Help & Troubleshooting

I bought a Magic Sim Elite for my Samsung Note 3. I have two sims that are on the Bell network. My phone is unlocked. When I insert the Magic Sim I can see the app Dual Sim which does not seem to work and at the top of the screen I get an icon which is a circle with a line through it. This icon is for no network found I believe. I try to make a phone call but is says no network found. If I open the app I can see sim 1 and sim2. There is a star beside sim 1. If anyone has any information on this or can help I would greatly appreciate it. Thanks.

[Q] Galaxy Tab SIM card

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?

Streak / SIM problem

My screen broke and i got a replacement from Dell. But after inserting my SIM and SD card the device boots but does not ask for the pin code of the SIM. I'm not able to call and above the screen no provider is visible. It does recognize my sim because the sim manager knows it's a vodaphone sim. But all the relevant settings in the menu are grey and at some places the message 'network or sim error' appears. If i put my sim in my iphone, it's working fine.
Any idea's, please?
Problem solved. I connected my streak to wifi and it said that an update to Android 2.2 was available. After downloading and installing the problem was solved.

[Q] SIM locked

Dear all,
I have an issue with my Omnia 7 and need your help. My phone is Unlocked T-Mobile Brand. I can use SIM cards of several company except the one I use regularly. When I insert this SIM, phone is SIM locked and phone function is not working at all. When I press on phone tile, it brings me to home screen. SIM card from other providers work fine. So it is strange to me.
Could you help me? I want it to work with this SIM.
Thanks
That sounds very strange. Surely it must be something to do with that particular SIM card if your phone is SIM unlocked and other providers are working?

Would some one give me a hand setting my Note 3 up.

So I purchased a used note 3 ( N900A )
I just switch to straight talk. So I had a full size sim and cut it down to fit my note 3 . When I try to go into my apn setting it says insert a sim or something like that.
I know the sims registering , to the phone I can read stuff from it.
So has any one went down the road I am . Is my sim locked or something like that.
Also there is an app called "Sim App." it will first say icc-id and give what looks like about 15-16 numbers then click ok it reads imei check sum gives 4 digits next reads random number gives 8 numbers.
then asks for an unlock code . If entered wrong it will say you have X amount of trys lefts.
Does this have anything to do with why my sim card is not registering to the phone?
Do any sim card works in the phone? Does your sim card work in other phones? Was the phone tested with a sim card before purchase? Was the phone locked to AT&T?

Yes if I switch the card to the other phone . It works.
Im not sure if this matters the orginal phone was a throw away`alcatel. Its not a smart phone.
Are you using the SIM card in another phone that also uses a micro sim? Does the note 3 recognize any SIM cards?

I only have this one sim .
The note is reading the sim card with certain aps . You know how if you up power up a phone , missing a sim it will say so if you pull down the top banner usually with a message like insert sim. When you pull down the top banner it doesn't say that . There is no warning about missing a sim . So it recognizes it has one . I can read stuff off the sim card when i open certain aps that are meant to access sim cards but when I go to change APN setting it will say insert sim card to access network settings.
Without another sim card to try in the phone, it could be the way the sim card was cut or there is something wrong with the phone.
Is the phone sim unlocked? Did you try a sim card in the phone before buying it?

I dont think the phones sim is unlocked.
No I didnt try a sim . It was from a family member so Im not to worried. The sim card works in my throw away straight talk phone.
How do you unlock the phones sim?
BTW thank you for your help.
In order to determine if the phone is sim unlocked, power off the phone, insert a sim from another carrier, and power up the phone. If phone asks for a network unlock code, the phone is not sim unlocked and you will need to get an unlock code.
Was the Note 3 n900a from AT&T?

S7 Edge dual SIM control

Hi Guys !
I have a Samsung S7 edge duos, for which i want to use two SIM cards - SIM 1 is my home SIM, and SIM 2 is a Global roaming SIM with data and Voice.
My question is whether its possible to set my phone in such a way that when I go on roaming i want my SIM 1 to deactivate data services and SIM 2 data services to kick in, since this a global SIM.
Is there an App for that or is there some kind of settings for the same.
Help in this regard would be highly appreciated.
Thanks
John
Not sure if you can do this, maybe with a task scheduler? Best choice is just to manually set your SIM2 to be the main SIM.
The only thing that might work is to call transfer sim 1 to sim two so that any calls received will ring on sim 2 which you can select as the active.
You can not cross connect the apns since they are linked to different sim cards.
Did you try all the dual sim manager apps? they say they do just that!!!
