Hello everybody... I own a Coolpad 5380CA bought in China and it works very well in my country but it doesn't get the 4G connection in SIM1, only in the SIM2 card. The problem is it only has 16GB RAM memory so I use a 16GB microSD in the slot 2 of the phone (the one to this) and I have to put the sim card in slot 1 (the one with the 4G problem). Some time ago I switch the sim card to slot 2 and when I returned to slot 1 it GET the 4G connection, it works well for a while but this week the 4G signal was lost again. I use the *#*#4636#*#* code to see the information and in the "Set preferred network type" appears "Unknown". Whe it was getting the 4G in slot1 the configuration was the same, when I put the "LTE/GSM/CDMA auto (PRL)" it doesn't recognize the 4G and when I put the option "LTE only" the signal is lost...
This is an annoying thing because in slot 2 the sim card works very well, and it gets the 4G and 3G radio frequencies, but I have to sacrifice the use of the microSD card and lose 16GB of storage...
Any help will be welcome... thanks to everybody

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.
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...
Hi,
I have a dual sim Honor 6 that has been imported from China.
I bought the phone for this set up - 4g data card in sim 1 for data only (can get 90 days 6gb for £15.00) and a cheap 3g card in slot 2 for calls and messages at £3.75 a month. total outlay for 4g, calls and messages = £8.75 a month which suits my needs very well.
I got my data card yesterday and registered it with the provider.
This is the problem I have - neither of my sims works well at all in slot 2 for data - speeds of 0.12Mbps on each card at best.
When I have each sim individually in slot 1 without the other card present I get 50Mbps on the 4g data card and 13Mbps on my 3g card.
When I then introduce my 3g card into slot 2 to sit along side the 4g data card that is in slot one the 4g speed drops from 50Mbps down to 4Mbps.
Clearly, what I would like is to get 50Mbps and take texts and calls on my 3g card and I am stumped as to why this is not happening
Has anyone had a similar experience or even not and have the knowledge of how to fix this problem?
I've contacted Honor UK and they politely said that they can't/won't help as it is a Chinese import. My data and telephony providers have no idea and suggest that there is an issue with the phone.
Cheers
Nigel

Second sim slot supports 2g only. That means EDGE network speeds, that translates into a maximum 238kbps theoretically.
Hope this helps

Hi,
Thanks for your reply. I'm coming to the conclusion after doing some more digging that the 3g card that i have in slot 2 is conflicting with the 4g card in slot 1.
I think what I need to do now is get a 2g only card and test that along side the 4g card.
That's my next problem - do any providers do 2g only cards as nearly all plans these days have some sort of data attached to them.
Can the mobile provider switch off the data part of the 3g card if i can't get hold of a 2g card?

As far as I know, it doesn't matter what kind of sim card do you use. If the sim is in the second slot, phone will automatically use 2g for network data and calls.
If you're hoping for better data speeds on second sim card, it's not possible using this phone.
Hello,
I'm in Germany and thatwhy I ordered the GEM-701 Version. Have 1&1 (D2) contract with 4G. Unfortunately I only got HSDPA signal ? displayed even in areas where surely 4G is available.

Are you sure your SIM card compatible with 4G (older card maybe not working)?
Try in other 4G compatible phone, if not working need to change to one new!

It's normal that the options are grey, if you only insert one SIM card to Slot 1. Then slot 2 can be uses for the external SD Card.
Slot 1 is configurated to all types. GSM, UMTS, 4G( LTE).
If you turn data on and you are not logged into a WLAN a icon will show for example E (edge) if you have a slow net.
If you are in the near of a LTE transmitter of your provider and you contract allows to use 4G, you would see a 4G icon.
Maybe you have disabled LTE: go to settings Mehr ,Moblifunknetz, Bevorzugter Netzwerktyp and Lselect GSM/WCDMA/LTE
Maybe the entry below "Betreiber" is wrog, or the ADB settings (Zugangspunkte)
Hello,
I'm totaly stupid.....I have tested a lot without success.
After some thinking I found in internet that vodofone dont have a contract with 1and1 for 4g. I checked my contract and remember that I did not have a 4g contract.
So the mediapad x2 should receive it, but I do not have a contract for it.
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.
