Wifi Xoom + GSM\UMTS MiniPCI board = GSM\UMTS Xoom

In the ifixit teardown of the 3G xoom... there is (in step 8) a blank mini-pci board, presumably for the LTE upgrade.
If this is also present in the Wifi Xoom, and this card were placed in it's place, and the appropriate coding was done, would it perhaps ... function?
Just some thoughts...

Damn, serious? I'm kinda curious too now!

I say buy it and give it a try in all honestly it would be pretty cool if you could use it

Where would a sim card go on the wi-fi Xoom if you did this?

If you can get Linux source drivers, it might be doable, but you'd have to figure out a way to get the drivers to link up with the Android data layer (not sure if that's easy or hard)...

Wifi only Xoom has a sim card slot.
But I'm not sure if it has a pci slot.

It does? Damn, I should look more carefully I wonder if you can do anything with it... Like retrieve contacts stored on a SIM.

There was a similar thread already here somewhere. It would be great if we could achieve this, but it'll surely require a lot of coding

I think the minipci card has its own sim slot. i don't think it would interact with the xoom's own sim slot (although it looks like there is the contacts for a sim on the wifi xoom)

NO the mini pci card communicate with the onboard sim slot through the bus just like in some laptops/netbooks/umpc like in the samsung q1u, I have 2 of these units the cam with onboard sim slots but no radio I bought 2 radios from ebay install them in the minipci slot and the onboard sim slot works.... I'm thinking of removing one and try it in my xoom wifi... they work native in many flavors of linu, in android x86 2.2 is scans mobile network but take forever.... so i still dunno....

The Broadcom BCM4329 chip that all Xoom models use is WiFi/BT/FM (both receive and transmit).
But that's a moot point if they haven't connected the appropriate I/O pins to those of the CPU.

Is there an app to run on xoom and see what devices are recognised by the operating system and which are recognised but missing the drivers? Kinda like the device manager on windows?

[Q] Dual SIM adapter for Defy - Where and Which to buy?

Hi,
Im seaching for a Dual sim adapter for Defy, regarding im from brazil so the best is from ebay or dealextreme.
Do somebody know where and which dual sim adapter to buy?
post the links if you can.
Thx

MAGICSIM 28th gen PLUS is what I'd go for. Seems to be the only reliable option

hi there, do you know if this works reliably with cyanogen 7 ?

Yea I'm sure it does

Oh btw i've just ordered the new 28th gen+ from these guys www.magic-sim.com so far its been an excellent service and everything seems great.

seems promosing and good but very pricy

I didn't think is was pricey at all when compared to the other options.

Which one did you get the no-cut or cut model? Compatibility guide says no-cut model fits but I don't see how it could go in Defy without stripping the metal part from SIM-card slot.

I was looking into this the other day actually and it does seem possible. Check out this picture...

Nice! I was thinking if it is possible to push the adapter from bottomside under the metal part and then push the sim normally in holder and according to the picture it seems possible! Excellent

Yea it looks good.
I've ordered one from the link above that Rhousman posted. I'll let you know how I get on if anyone's interested?

Hi there ... yes it would be great ... so did you ordered not CUT model? Thinking bout the same.

I bought "28th GEN PLUS (3G/2G) DUAL SIM CARD ADAPTER - NO CUT MODEL" from http://www.magic-sim.com/ and it does fit in Defy and it seems to be working.

When in use the sim toolkit changes SIMs and even mobile data seems to be working. I have to test it later.

Do both sims work simultaneously?? Say, could i connect to the 3g on one sim and call a contact on the other sim, simultaneously?

does it reboots when change form sim1 to sim2?

Sent from my MB525 using Tapatalk

All working good here. No need to reboot when changing sims or anything like that

tnx. but I did not mean that reboot is needed. So its hot swap?

I didnt get it. In old mobile phones with such adapters the only way to change sims was reboot.
In some DUOS mobile phones two SIMs works in the same time and you can select one or another to call someone and receive calls for both. Also two signal strength bars are displayed.
But how this adapter works with Defy?
Thanx!

[Q] Sim Card Tray

So I've been switching my sim card between my nexus 4 and the note 2. Well yesterday I lost the sim card tray. Does anyone know where I could get a replacement?

I don't know. But, if you're willing to just commit to the N4, you might be able to take the back off and stick the card in the slot permanently. Maybe.

maybe an iPhone one could work?

Good thought, but it doesn't look like it: the outside cover plate is larger on the Apple tray and there's more distance between the outside cover plate and the edge of the SIM card than on the N4 tray.

Oh nevermind then, I haven't receive my nexus 4 yet and the pictures of the Google's tray I found were very unclear.

Did anyone figure this out??
I broke the plastic off of the sim tray by mistake!
I need a new tray

You could try calling LG, they have replacement parts and I'm sure this one isn't the most common replacement so they should have some in stock. 800-243-0000 You could try calling them to see if they have them available.

Anyone have any luck?
I just broke the front plastic bit off of my SIM Tray. It looks horrible.
I can't find anything on eBay.

You all need to be more careful!
But seriously, this is probably something you need to contact LG or Google (not sure who is in control of hardware support) directly, because of the fact that they put the IMEI number for the phone on the tray itself. I doubt this is high demand item at this point in time, so you most likely won't have luck finding one from a third party, and even if you did I'd imagine it'd be very high in price.

Just incase anybody reads this and has a Nexus 4 Sim Tray they would sell - PM me because I am looking for one!

So last night I took my sim out to test tmobile sim I have. Then a friend came over and while I was outside talking it vanished somehow.
So now i cant find my sim or the tray. I'm going to order one, like $8. But crap. Can't believe I lost it. I searched this living room, flipped the couch over.
Maybe the cat ate it. Haha

Edit: So tonight I get the change jar and pour it out on the table. There pops out my extra sim and the tray. Last night I had slid the card in without the tray and it worked just fine. I wasn't without a phone without the tray. Sure was nice to find it. I knew it was in that damn house.

Head's up! - XT1607 Moto G4 Play uses Micro SIM, not nano Sim.

Just got a new XT1607 Moto G4 Play for my wife after her HTC One Remix from VZ died and I went to pull the Nano SIM from the HTC and pop it into the XT1607 and, low and behold, the XT1607 uses a Micro SIM, not a nano SIM!
Bummer!
I was able to pull the Micro SIM out of a recently deceased VZ LG G4 and got a great phone support tech at VZ to enable it in the XT1607 and it worked!
Can't believe Moto/Lenovo released a new phone in 2016 with a Micro SIM. WTF? Oh well, you've been warned.

This can be known in advance obviously.
Universal sim kits have a nano in micro, I have lots of them like you can get a free sim from T-Mobile store and just snug your nano in the micro.

I mean, it's kinda right there in the spec sheet and item description like ANYWHERE you can buy the phone. Seems like a pretty hasty purchase if you don't even know what's compatible with it.

Have the adapter from tmobile

Not really sure why they have to make these cards smaller and smaller. My iPhone 6 had a sim tray in that was bigger than the micro sim card yet they say its for size reduction. Oh well, I prefer the micro sim anyway, easier to deal with!

In say the OnePlusX they offer either a 2nd SIM or a SD card in the same slot, a dual SIM tray. Makes sense in some phones.

isnt there adapters in ur country? i have bought 3 for 1 dollar and we arent a first world *****

I noticed that the SIM (nano) with adapter (to micro) is pretty hard to insert, and very hard to take out.
On SIM 1 tray, there is a slider that pulls the SIM out a bit; I couldn't take the card out without it.
But there is no such thing on SIM 2! I didn't try to put a SIM there because I wouldn't be able to take it out...
I am using an adapter like this - Noosy. Did anyone have a different experience, with a different type of adapter (that maybe doesn't make the SIM thicker)?

Listen there is an easy way and a hard way.
The easy way is the "punch out" fitting method where you have some SIM you got from whoever (say a free one from Tmobile) which is the 3:1 type, you punch out the micro SIM to nano SIM shape and place your nano SIM inside so its flush.
The hard way is the "overlayer" method where there is solid plastic on the side not not presenting the gold pins, that is nasty the nano SIM can get stuck easily as the solid plastic forces the nano SIM to protrude. Looking at what you did you picked the harder method.

The ideal method is find something like this

}
You place your nano SIM inside it so its flush both sides, then it slides in+out easily in the slot in the G4P.
You can get this usually as the SIM you got came in a 3:1 type punch-out and this is the middle punch-out.

Are the Sim trays from the single sim variant compatible with the duos?

Recently my sim tray got stuck in my phone (G935FD) and upon trying to remove it the tray snapped and the Sim stayed. Needless to say I tried a few measures including using a strip from an old bank card to create space and get it out etc. Nothing worked, I got it professionally taken out and they gave me a new sim tray as well. However the tray is for the regular single sim version. I don't care for the second sim but the issue is now my SD card isn't reading, I've troubleshooted the card and it is in fact good and working. But I'm wondering if its the tray (despite the Sim 1 working fine) or was it a hardware problem when the tray stuck or during repair. Any answers as to if the tray can cause this?

Have you checked if the trays are facing the same side for the SD card on the old and new trays?

I just checked it to be sure and they look identical to me other than the little notch to fit the second Sim. I have a friend with a duos as well. I'll ask to try theirs to verify. I just found it odd because in my previous experiences to damage an sd card reader was tough lol. It may have been damaged at some point during my tinkering or the repair so I'll also ask the repair guy to give it a look again even though I'm uncomfortable with opening up the phone so often. If it's hardware I'll order a replacement depending on the cost and quality. If not I'll just go without an SD.

Looks the same. Yeah, most likely there's damage like a bent connector or something.

Yes, the sim tray from the one sim variant is competible with 2 sims variant,
but it is not as same as together.
1 sim variant can be modded to 2 sims variant, and you should use the 2 sim tray

Only the sim tray can be modded. Meaning you can get a sim tray from 1 sim variant and mod it to be used in 2 sims variant. You can't mod the phone and turn it to 2 sims variant.

Apparently you can on the Exynos variant.
You need to be on Nougat or Marshmallow, I believe Oreo isn't supported yet, and you need a Z3X box or Chimera, and a dual SIM tray.
