Confused and Stressed Sim with Wifi?

Hello all,
i got my Xoom from my friend. He told me that it is a WIFI Xoom. it is mz604 but it has a Sim Card hole ?
What does it for ? i live in Turkey. is it for 4g or cdma only or it is only for decoration ?
i succesfully flashed Turkey FW and mobile network is disabled. i checked out Turkish xoom when you take out sim card its mobile network is disabled too.
i wonder that sim card socket is working or not ? if it is working i can transfer it to 3g (i think) but if it is cdma or 4G or whatelse it is only a fantasy.
What do you think guys ?
The SIM card slot is not connected to anything in the WIFI Xooms, however, the SD card slot is in that same area.

[Q] hardware differences between US verizon 3g and UK 3g

Hello all
i have a verizon 3g xoom. it's not upgraded yet. i live outside us
about the UK 3g xoom, can it operate 2g sim card? for sms, gprs or ...
how about normal 3g sim cards?
is there any hardware difference between mine and uk one?
may i operate my 2g sim card on my xoom? how about 3g?
when i put sim card nothing happen. i just tried 2g sim card
our 3g operator is not started selling sim cards ... but we have 4g operator.
if i install uk xoom's rom on my own, can i use sim card?
is there any mini pci-e card that i can use my sim card with it? (self upgrade xoom with custom mini-pci-e)
please help me. i need some information. i'm confused.
http://forum.xda-developers.com/showthread.php?t=1263634
how about this thread? i've done that but dont work for me. there is no signal, i think it didnt recognized my sim card.
if i install the mini-pci-e card that motorola installs on xoom during upgrade, can i use sim card for 2g/3g ? (sms or internet)
i have found this : "If you bought your Xoom from Verizon, it will have no SIM card slot. Verizon's CDMA network doesn't use SIM cards. Also, if you bought the Verizom model, it will only work on Verizon, and not another carrier. There is also a WiFi-Only Xoom, and it does not have a SIM slot."
here : "http://www.ifixit.com/Answers/View/53440/Why+I+can%27t+find+3G+SIM+Slot+in+my+Motorola+Xoom"
but mine have sim slot with a plastic sim on it.
The Verizon 3G Xoom does have a sim card slot but no hardware inside to read the sim card. That is what the 4G upgrade was for, to install the hardware necessary to utilize the sim card for the Verizon 4G LTE network.
I don't know if anyone has gotten a Verizon Xoom working on any other carriers network.
Theres pix of the inside of my Uk3g Zoom somewhere...

Sim detection slot 1 , Indian version E8

Hello Everyone,
I am facing this weird issue. Mine is a dual sim E8 and I was using Airtel provider on my sim slot 1.
The moment I landed in US and when I powered on the mobile, it was showing no signal . Till this moment I havn't changed or removed any sim card. The settings are still untouched and even the sim tray has not been removed ,airtel sim in slot one and no sim in slot 2. Later I changed the setting to manual mode , I saw a pop up displaying sim card error and "unable to find network, switch to global mode"
Then i moved the Airtel sim to slot 2 with slot one empty. It asked me to select Tmobile or ATT as partner network. I went with Tmobile as roaming partner.
I wanted a dual sim , as I was hoping to use Tmobile/ AT&T sim on slot one and keep Airtel sim on slot 2 when I reach USA.
Later , I brought a Tmobile sim and put it in slot one, same old error pop up, but it worked in slot 2 ( Edge )
I reached HTC chat , its the most horrible experience i have ever had. The moment i tell them my issue, chat window loses connection as if someone has disconnected.
Finally when I did get connect , by checking my IMEI, chat representative told me that slot one wont work for roaming as its CDMA, only slot 2 works for roaming.
I just couldnt understand this, I was using airtel GSM sim in India with 2G internet. how come an unlocked device change to cdma while roaming outside India.
Please let me know how to work on sim slot one issue. I love this mobile a lot , even if i get 2G on slot one , i will be very happy
Mobile is in stock condition purchased 2 months back, I received a factory update to 5.0 through OTA

Metro PCS - NO SIGNAL

I got this phone for my dad off swappa.
When he puts the sim card into the phone, it shows Metro PCS (t-mobile on the cheap) and after about 5 min it says "Emergency Calls Only" and has no signal.
Is there something that needs to be done? The sim card works in his other unlocked phone fine.
Attached is a photo.
Have you called Metro PCS or talked to T Mobile yet? Sometimes they can do settings or carrier specific changes that might help. I popped my TMo Sim in a d it's worked fine since.
I found the issue. MetroPCS locks imei to sim. So his old phone was the only imei registered to be used with that sim card. You have to call and swap phones and they lock the new imei to the Sim card.
