First, no 3G doesn't use cards, it's built into the Xoom. Second, the 4G has a card, and it trasmits in different frequencies than Germany carriers do, so you most likely cannot swap the SIM cards.

True, there is a slot in the Xoom with a dummy sim card that reads something like put a sim card in ONLY after 4g uprgrade, so thats not possible.

seems i've to wait until t-mobile will release it ... damn ...

Even then the 4g modem is the only thing that will use the sim card. The LTE frequency will probably only work in the US.

There are two technologies used in the USA: cdma and gsm. In the EU typically is only GMS.
The xoom that was released in the States has the cdma technology, as for the LTE, it’s been deployed first here in the states.
Since you are in Germany you could use the xoom as wifi only.

Purpose of Sprint SIM card??

What exactly is the purpose of the Sprint sim card? I went to Russia and got the phone unlocked by Sprint, put in a Megafon gsm sim when I got there and accidentally allowed my Sprint sim to get destroyed in the washing machine. So when I got home I expected my phone to not work, but I figured I would switch it over to CDMA just to see what would happen and it works perfect! So I am confused as to why the Sprint sim is even there, is it just a dummy card with no real purpose?

The SIM is for LTE service. CDMA will work without it.

That cant be true. I had a galaxy nexus on sprint and the sprint variant had no sim slot and connected to 4g lte when I was in the area.

Back then, the sim was "integrated" into the phone.

Different phone different configuration.

Both the gnex and evo 4g lte had embedded sim cards.

Dang! Is it really that much? Not only is $50 many, many times what it costs Sprint to procure the SIM card (which I would guesstimate at less than 50 cents a piece), it is also a lot more than what the other US carriers charge for a SIM.

I thought the purpose of the Sprint SIM card was to enable Sprint's Worldwide services. Where does it show you need a sim for LTE?

You can ask Sprint (I wouldn't count on the clear answer though) or just get to the LTE coverage area, Sprint stores have LTE 4G and pull the SIM out to verify that you cannot get 4G without it.

The primary purpose of the SIM card in recent Sprint phones is to provision LTE. While previous Sprint LTE Android handsets did not have a SIM slot, they still had a SIM, it's just that it was an embedded/soldered/non-removable type of SIM card.
If you take the SIM out you will not be able to register on Sprint's LTE network.

dont need sim

you do not need a sim card fir lte. You do not need the sim at all while in USA. It will connect to the lte network without it.

Are you sure about this? When running a Verizon ROM on sprint without the proper tweaks, you will get am error about LTE not being able yo connect because it doesn't detect a Verizon sim card. 3G works though.

You are completely wrong. The phone will definitely not connect to Sprint's LTE network if you take the Sprint SIM out. You will only get CDMA service.

i will when in a 4g area. i am not sure how to show the sim status at the same time as it is not displayed. Since you dont believe, you can contact radio shack in the twelve oaks mall in novi Michigan. They do not have sprint sims and I was in shock when they actually activated the phone because I was thinking I would need to go get a sim card, but it is not needed.

Can you activate a verizon s5 on tmobile?

the title says it, i kind of want to do this, maybe not for that long, most likely it would be temporary.

No. Google it and you will find that Verizon and tmobile networks are different. Verizon is CDMA and tmobile is GSM. Or something like that.

It not true. I confirm LTE works fine with out any problem.

If you are able to use other carrier phones and just pop a Sim card in and your good to go, then in the future can I buy a variant of the phone I want with an unlocked bootloader and be rooted with no issues?

Nope, i'm actually surprised that Verizon didn't lock the phone if what the above poster said is true. The bootloader isn't what you need unlocked to move from carrier to carrier. Phones with sim cards are generally GSM and phones without sim cards are generally CDMA. GSM phones are normally locked to the specific carrier that you bought it from. CDMA phones are not usually taken on any other networks unless you are moving to a network like cricket which takes what it can get

As he said, Verizon 4G phones are all sim unlocked. Phones like this and the Note 2, which I just came from, have the CDMA and GSM bands. It is just as simple as putting in the SIM, change the APN, and be working. That said, the Note 2 could not get a 4G GSM signal only HSPA+ because of the bands it supported. I haven't checked the S5 yet, but I do believe I have seen that it does support some of the 4G GSM bands.
You are right about the CDMA part which is why it wouldn't be wise to buy, say a Sprint S5, and then come to Verizon because it does not support any CDMA bands.

so you guys can confirm that it is sim unlocked?

They always are. All Verizon Wireless 4G phones are SIM unlocked.

Bare with me if this seems like an absolutely stupid question.
When I travel I have a GSM HTC One S that I pop in a pre-paid SIM to use (say, 3 in Ireland). I believe this was a T-Mobile phone previously that I carrier unlocked. If I have a Verizon CDMA S5, I could pop in the 3 SIM and be able to use it (maybe not 4G depending on the bands) provided I updated the APN information?

Correct. I used my Note 2 in multiple European countries, lastly in Rome where it was stolen. Take your Verizon sim out at the airport, put the new one in, change APN, and voila.
(carriers I have tested with - Orange, Vodafone(multiple places), 3, Rogers in Canada)
Your S5 on Verizon isn't solely CDMA. If you look up any website with the bands it supports, you will see the GSM bands.

More than welcome. And here is the link so you can check the bands when looking at foreign carriers.
http://www.phonescoop.com/phones/phone.php?p=4408
And even without 4G, it is still plenty fast enough to use the internet, google maps, and stream music.

What if you canceled your service and went to tmobile. Would it still work?

Looks like the One S and S5 share the same GSM bands... I'll definitely have to try it out. I know my 3 SIM works here in the US too on the phone. Thanks again, really helpful.

Same story. Few days ago I bought this device (G900R7) on ebay. I thought it was CDMA+GSM phone, like G900v and G900p, but I was wrong. It turns out, that this phone is CDMA only. There are no CDMA networks in my country.
SIM card slot is for 4G LTE internet ONLY. Phone can't ever discover gsm networks.

if thats the case, its quite unfortunate and you have my sympathy. But it just seems odd for that to be the case. The only 2 versions that i was aware of that physically differed from one another were the xynos vs snapdragon processor. Other than that it just doesnt make any sense for samsung to have had taken gsm capabilities away. The radio firmware very well could be written to not look for gsm networks, and that might be an obstacle that isnt something we can fix, but i seriously doubt that its a physical thing

To clarify, the question is about enabling 3G/4G for both SIM-cards at the same time AFAIK.
Using 3G/4G on SIM 1 or SIM 2 works, just not at the same time.

You and me both, I just made the "cutout" trick so that I can have a microSD and two SIMs at the same time but apparently my work SIM only supports 3G and 4G while my own supports 2G, 3G and 4G. I have 50 GB data on my own and 500 MB on my work SIM, so I wanted to split them that way but now I'm stuck with 0.050 Mb/s data speed on my own SIM and a microSD with a glued SIM-chip from my work phone which I don't know if I dare remove without damaging it - and if so I don't even know if I can manage to put that chip inside another phone again
Strangely enough my work SIM allows 2G roaming to Denmark (in south-western Sweden we can easily reach the Danish cell phone providers) but I don't think my employer would be happy with me racking up roaming fees of several hundred dollars per month.
I really hope there will be a fix/ROM-hack for this but I fear that it has to do with the hardware - I think it needs two 3G/4G radio chipsets (don't know what it's actually called) and only has one, just like a cheaper TV does not have PictureInPicture because it has only one receiver
But to answer your question I found a thread on another forum, but I checked the rules and I don't think I'm allowed to link it so google
"Best DUAL SIM android phone?" post 1993
and you should find it

On Chinese version, you can combine the data of both Sims to get a faster overall network speed.

A dump question. Does anyone with the plk-al10 vervion noticed that when changing from 4g -sim 1 to 4g sim 2 the phone remains for one second on 3g on both sim's? I believe that the hardware is no problem. The only restriction is by software.
