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] Nexus 5 - Not working on particular network

Hey guys could u please help me out as my nexus 5 is not working on Airtel, but is working on tata docomo ( I stay in Hyderabad)
I'm not able to understand as both are GSM and if the phone is working on one sim , it should accept the other too
By the way the phone is imported.
Pls help.
After inserting airtel sim, the phone connects to the signal and then loses it every second

Airtel sim connectivity issue
I have got my nexus 5 last novemeber and got it for service at an authorised service centre because of a blur screen issue. Now that issue is cleared, but i find it difficult to get a good coverage for airtel network even at places where airtel has good coverage. i have tried other sim (vodafone) as well and it works perfectly. This is not an APN issue; i have used the same airtel sim for almost one year in the same device
I took this to service centre and demanded an explanation, but they are saying other sims are working fine, and hence it is an error caused by airtel network.
I took a duplicate sim and also tried my sister's airtel sim. Both instances gave the same results of poor network connectivity.
Can anyone help??
i have tried factory reset as well... so i am almost out of options...

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

Galaxy S7 Dual SIM (SM-G930FD) Tethering SIM 2

Hi guys,
I bought my G930FD about a month ago and I have started running into a rather annoying problem:
it seems that tethering only works if SIM1 is use for the data connection. If one attempts to use SIM2 for data and then tether (regardless if one uses WiFi, Bluetooth or USB), the connected PC is unable to use the internet connection. I tried several ROMs (including unadulterated G930FD stock) and SIM-cards (Vodafone NL, Base DE and NTT Docomo JP). Nothing seems to help, so I am now asking you guys. Is there anybody who has any idea how to fix this? I recon the trouble lies somewhere in the tether settings that doesn't get properly switched to SIM2 data. So any help would be greatly appreciated.
What if you're on SIM 2 but turn data off for SIM 1? (or turn off SIM 1 completely)
I'm experiencing the same problem. On a dual sim S7 edge and when tethering the connected system just can't get on the internet. Also switching the sims to other slots doesn't seem to work. The strange thing is that tethering does work on one of the sims but only when roaming...
Same problem! Any solution?
Sorry to ressurect this thread, but I just bought a J7 dual-sim and am having the same problem (hotspot working only with the SIM that is roaming, but never with the non-roaming SIM). Did anyone find a solution? This is extremely annoying, if it cannot be fixed the J7 is clearly very poorly made.

Simple sim data switch

Hello fellow members, I have a bit of a more complicated problem.
I have a dual sim Moto G2 capable of handling one sim in 3g network and the other in 2g network. In SIM slot 1 I have a Digi.Mobil sim card with unlimited data. In SIM slot 2 I have an Orange sim card with few GB of data.
The Digi.Mobil sim card gives me no signal when I am at my office so I need to use the Orange sim card to be reachable. To use the Orange sim card I have to go to settings and manually select it as the data sim. This makes the Orange sim as the 3g sim and the Digi sim as 2g sim.
When I leave work I could leave the Orange sim as the data sim with 3g and Digi sim as 2g. The problem is that the Digi network does not accept 2g. Only 3g or 4g. This means that for the Digi sim to work I have to switch it back as 3g and use the Orange as 2g and use data from the Digi sim.
Is there like a super simple widget or way to just say: OK now i want to have net from Digi and automatically set it as 3g, and now I want to have net from Orange and set that one as 3g? Or is there a way to have 3g as preffered network for Digi while using data from Orange as 2g?
I know the problem is a bit complicated but I really appreciate any help on this.
