While disabling an ATT lumia 640 I found that there is a second sim card slot. Found that Tmobile MetroPCs all have the second sim slot. A separate plastic named "sim locker" is used to block the place which can be easily pushed away. On the motherboard i see the sim connectors are there. I am unable to upload the picture of the 2nd sim slot as i am new here.
A simslot can be easily soldered in there. I also learned that a dual sim firmware may also be flashed from here http://forum.xda-developers.com/windows-phone-8/general/brand-att-lumia-640-lte-t3294971
I was wondering will it work ?
Need to flash a 2nd IMEI though.
im new to windows but how do you plan to flash a new imei you can restore it but how flash it is it done using the same imei as the previous

I pulled the SIM card out last night on my Note 3 and then put it back in. After booting up , the phone showed a "No SIM Card" error. I have tried to re-seat the card and have rebooted many times and it still does not work. My old Note 2 is being used by my son so I put his SIM card in my phone and it works just fine so obviously its a bad SIM card at this point which I confirmed by putting it in the Note 2 and it said the "No SIM Card" error. At this point I just need to go to Version and get a new SIM card. The question I have is, do I need to wipe my phone and put it back to a stock Rom or will Verizon just give me a new SIM and ignore the fact that it rooted? This issue really isn't a warranty situation so I was hoping to not have to go through all of that.

Why not use your son's Note 2 (unless it's also rooted) and get a new SIM Card? It doesn't matter which phone the sim card is put in, as long as it is associated with a Verizon phone number. Then you can switch the card back. I don't know if Verizon keeps track of "rooted" phones by customers in case you try to reset your phone to original and then claim a warranty.
Just my $0.02.
Cheers,
B.D.
I went ahead and did a Nandroid backup and then reverted it to stock and will switch back after.

I usually swap sim cards with my phones when i need to and never have a problem. One time it wouldn't read and i had to use a screen cleaning cloth to wipe it off and it worked again.

Hello!
After a power off I can't boot CM7 on ZTE Blade because of SIM, without SIM works perfectly, it boots. It worked with SIM for 1 month, but now it didn't. I made a stock rom restore but no resolution. In other mobile the SIM card works, and another SIM works in ZTE Blade. It's weird. Is it a hardware related problem? But only with one SIM card, which worked before this?
Replacement sim

I had similar problem with my galaxy tab, it was a defective sim card. Try get a replacement sim card, or just try another sim card.
Hey there,
I got a I9505 that doesn't detect my simcard (if i put it in it still say pls insert simcard like there is none). so my guess was carrierlocked...
It also doesn't ask for an networkunlock code .. so i didn't wanted to buy a code on these websides because i didn't know where to enter the code.
Well I've tried the trick with the *#0011# and it doesn't go into the Service Menu.
The phone is on 5.0.1 could this be the problem ? Is there a way to downgrade?
Or do i have to falsh the modem in any way?
Till now i've just changed the FW with Odin to the DTB Version.
I'm kind of scared to try other things if I'm not sure what they do...
I'm really sorry if the solution is in a thread i havend found or just overlooked
thanks for your time and help
A properly working SIM lock would recognize the presence of the SIM card, and when you unlocked the phone, would prompt you to enter the unlock code. Therefore, a carrier lock is not the source of your problem. Unfortunately, yours is a hardware problem, and based upon your description, it's a motherboard failure, rather than a SIM card tray failure. It cannot be the SIM card tray because a SIM card tray failure would not ask you to insert the SIM. Instead you would have a circle with slash in the notification bar to the right.

Thank You for your help,
So in the mean time I successful downgraded to 4.4.2 (cyagogen)(and upgraded again) found a soulution to flash and access the modem so i could do the trick with *#0011#...but it's still not working.
I just don't to belive that its a hardware problem. Is there anyway of another software Simlock?
Because the Network Conectivity bar is showing 3 bars.
I got it (not so) cheap from ebay, so could it be that the imei is block in the network ?
Thanks agian for your help
IMEI could definitely be the cause of your problem, especially if you actually do have a signal.
It is showing 3bars but not the H for HSDPA but it also shows those bars if no sim is insert so...
The imei ist blocked ?
Guess there is no way to change it

If no SIM card is inserted you wouldn't have any signal, but a missing SIM card indicator. This behavior confirms to me that you have a hardware problem of some sort. You need to have the device looked at, because software is unlikely to be the source of the problem.
I have been trying for the last few hours to get my UK Moto X Force to accept a dual sim configuration to no avail. I have listed the different methods I have tried below hoping that someone can identify a solution.
1st Method:
Rooted my phone and used the instructions for the Moto X Play variant to enable dual sim functionality as listed here: http://forum.xda-developers.com/moto-x-play/help/enabling-dual-sim-single-sim-devices-t3225546
I followed this method through by adding the several lines of code to a local.prop file and rebooted. The phone now had access to the Dual Sim settings and identified my 1st SIM within the phone but not the 2nd. Where it said 2nd SIM 'No Sim Inserted'. I tried with multiple SIM cards and the same error popped up, there were no issues with the sim card touching the connector plates for the 2nd sim as they had scratched the card, a visible connection had been made.
2nd Method:
I installed a Mexican Dual Sim variant of the OS and inserted both cards. Bluetooth, WiFi and Mobile connection were not working however the Dual sim menu was available. I then flashed the UK modem onto the phone which fixed the WiFi and Bluetooth not working as well as the mobile connection. However once again only one of the sims worked and slot 2 was labelled as being empty.
Any suggestions on what to try next would be appreciated to get the dual sim functionality, functional!
Thanks
I think that UK edition doesn't really have hardware required for dual SIM. Tray is just generic for all Force variant.
Actually both of your attempts proved that. I would like to be wrong in this case
Any ideas?

Need to try. The files in the fsg folder are different. I did not succeed, but it should work, if someone seriously takes up this issue.
Has anyone got the modem files to flash?
I've mistakenly flashed the Brazilian rom on mime and lost wifi
Hi,
I'm assuming the following:
The A510* and the A5100 (the dual sim version) seem to be pretty identical according to their hardware specs.
The only hardware difference seems to be the slightly modified plastic tray of the A5100, which gives place to a 2nd SIM to be put in instead of the external sd-card.
It's seems only a plastic difference, as even the A510 has the right pins at the right place to possibly read a 2nd SIM.
Question is: How can I make the A510 register and make use of the 2nd SIM?
Would it be too weird to try to flash a A5100 stock rom onto the A510?
Should it be a 4file repair image, including re-partioning? What are the risks?
Which preparations would be necessary to prevent ending up with a brick?
Thanks for input, bibbbs
I thought the A510F is a dual sim phone? The sim 2 slot is also an sd card slot right? So maybe you insertrd an sd card in already?

The A510F is sold as non-dual-sim. Only in Asian markets they sell the Duos-Version A5100. Since the A510F sim tray lacked the small spacings to hold the 2nd SIM (but the phone's not lacking the PINs!) I've bought an A5100-sim tray. But after inserting 2 SIMs nothing like multi-sim control showed up in the OS/settings. That lead me to the idea that it would be only a matter of the right software ...
The A5100 stock rom has another PIT layout than the A510F.
Before I try to flash I'd like to do all it needs to happily go back to a working A510 stock in case it fails.
Do I have to root the phone first to make an backup of any unique EFS data or so? Or will that not be affected by flashing with repartitioning?
Btw, do dual-sim phone have two IMEIs? If yes, than I'm afraid it could be more complicated ...

The specs page says that the a510f has dual sim? And yes, dual sim phones have two IMEIs.
