this phone is supposed to support both GSM and WCDMA, but how come I can't use this phone in Japan that uses GSM network?
whenever I want to access GSM using the sim from my home country, it says something like "the SIM card does not allow to register to this network"
does anyone know what's going on??
thanks,
Dont take this as a smart alec response but is your phone locked to a network? Or is it unlocked?

You have to select another service provider, apparently your home mobile phone company doesn't have any agreement with the network you want to select.

Based on this:
http://www.gsmarena.com/network-bands.php3?sCountry=JAPAN
there's no GSM support in Japan. You need to be using the 3G 2100 UMTS band.
Also, based on that message it sounds like your provider doesn't have roaming in Japan, so you'll likely need a local SIM or use wifi. Unfortunately getting a local SIM isn't as easy for visitors to get in Japan as many other countries.
search the n1 forums for japanese sim info - i believe there are sim rentals
also call your carrier first to get the unlock code so the other sims will work
I had a similar issue with my visit to Punta Cana D.R.. Just got my sensation and I couldn't do anything with my phone. I called T-Mobile and they checked and I would have been able to use my phone IF I asked them to turn on international on my account (free). Go to your T-mobile account online and add that option, was told it was going to take 24hrs for it to be updated, dont know if you have to be in your Home network first for the SIM card update... new to T-Mobile and not really feeling the love from them.... Verizon was a rip off but at least I felt like I they kissed my ass for it..
Every network I have been on you have to call them and tell them you are going to be out of the country and you want to use your phone overseas. They will then enable your device to connect to whatever provider they have a partnership with. if you dont call and enable this your phone will not connect to the foreign networks. It will find them but not connect.
nodoby mentioned it by roaming with your phone COSTS a lot of money. so be careful if you don't want to have an heart-attack when you see the bill if i were you i would use internet calling. I think if you are on T-mobile they have a free internet caling feature.

This is true you can use internet calling from say japan to the US and you wont get dinged for long distance, however if you call japan numbers on the same wireless you pay just as if you were on the network.

So where i live we have another option for gsm networks called air fire mobile... I called at&t to get my unlock code after giving me my code they asked what my intentions were, i told them to switch networks. The rep then told me my inspire would not work on this other gsm network called airfire. I dont know if air fire is a national thing or what but in case not here is there web site. http://www.airfiremobile.com/
Well i went to airfire mobile and they said my phone would have to be unlocked so i had them put there sim card into my phone and nothing popped up for unrecognized sim card..... My g/f has a htc aria and she got the option to unlock sim she put the unlock code in she had received and it worked but her phone could not recognize air fire's network only there roaming service with is covered by at&t... is there something with HTC phones that will not allow us to use this network, or are there any steps we need to do once the new sim cards are in the phones like settings and apns numbers or anything? Please help looking to escape my raping by at&t each month lol
You should have no issues with ATT phones working on AirFire. Looks like they use the same bands as ATT. And maybe she was showing as roaming because she was actually roaming. There is only local coverage in wisconsin. This page shows everything you need to know except nowhere on the site does it say they offer 3G. I am guessing it is edge only.
http://www.airfiremobile.com/Support
thank you for you help, when i asked the lady if they offer 3g her response was we offer 2.5g lol im guessing that would be edge?? Also when i go Menu>settings>wireless and networks>mobile networks>Network operators: the only thing that comes up is at&t. This is with my at&t sim card in, but shouldnt it show airfire also? or does my phone need to be unlocked before it will show airfire?? so confusing lol
Is your phone sim unlocked? You said you got the code from ATT but never said if you were able to enter it sucessfully. Is your phone rooted? If yes then during the rooting process it will become sim unlocked. So if you phone happens to be sim unlocked then select "network operators" and do a search for your new network. And YES you have to have an AirMobile sim or all you will see is ATT with an ATT sim card.
Just in case you don't understand, you unlock the phone to use any simcard. You are not unlocking the sim card to use any carrier.
As far as data it is an ATT phone. It does not have the APN for AirFire Mobile. You will have to enter that yourself as a new APN.
yes my phone is rooted, i never knew that by rooting it unlocks the phone, maybe that would explain why when i put the airfire sim in the box never came up asking for the unlock code?
But even still when the g/f had the airfire sim in her aria and she unlocked her phone it showed airfire network but it was roaming.. and didn't show there home network, the rep at the store said it could be something within the hardware from htc??? and at&t told me my inspire wouldn't work on airfire because my phone was 4g phone.. which i dont see why a 4g phone cant come down to Edge network if thats what airfire is
Any ATT phone will be able to make calls and connect to data on AirFire's 2.5G system if thats what they call it.
Let's just say that the rep at the store should be selling shoes.

Your right the guy is stupid. First the inspire can't connect to att 4g network that is not even 4g. As long as they are GSM based you are at least gonna get edge. I don't even want him selling me shoes lol
i have a htc desire Z currently and i recently went to california to spend some time with my gf's family but my phone just did not work over in america....
im in a 18 month contract with Orange (or EE now) and when I got to america i was not registered to any UK carrier so I tried to connect to the two possible carriers available T-mobile and AT&T but both said my sim card was unable to register with these carriers.
i have no idea why or what causes this issue but i want to make sure that next time when i leave to go to the US my phone is going to work...
im getting a new phone soon and want to know what the fix is before i get a phone that wont work in the US again...
PS. im rooted and using a custom rom called mimicry if that has any foot on the problem.
thanks in advance
Are you still using the SIM card from the UK? If so, you need a US SIM card to communicate with the GSM towers here.

i brought my gf a phone a Tesco mobile carrier in the uk and hers worked over there... so some work, i just need to know which ones do or how i can connect to the gsm towers. i dont actually care about using the phone service too much because i mostly do my networking via skype and whatsapp but i was unable to access the wireless connection too (probably related as well)
no access to any signal was available. my gf had no troubles though, she texted and called and used internet on wifi but internet didnt work outside of wifizone which is the same thing im looking for.
bump - does anyone have any information on this?
I hear sth about it usa doesnt use umts and they have different frequency than Europe probably this is the reason

Before you buy your new phone, check on GSMArena for the full specs and see what frequencies it supports - then make sure those match with the frequency your planned provider in the US uses.
And, please don't 'bump' your own posts - there's no need and it's contrary to the rules of XDA to do so within 24 hours.

is there a possibility to change the radio part of a rom in order to use frequency to at least get onto a network?
my phone
gf's phone
it appears as though my phone has the ability to work in the US however it appears to work with either one or the other and not both at the same time... if i got that correct?
(seeing as USA coverage accepts UMTS 850, 1900, 1700 and 2100 and the UK uses UMTS 900 and 2100 i need to look for a phone that runs on 2100)
I am traveling to Canada, will use Rogers or other GSM network.
Can I simply switch sim card to use my phone on those network?
I only need to make phone call, and occasionally texting. I do NOT need data. I have seen people here discussion changing APN, are those discussion purely about how to use data?
I live in Canada, have a Verizon S3. I use it without switching sim cards without any problems. I do however have Canada calling on my plan. You can ad Canada to your plan for 15$ you'll get 1000 min I don't know about txt I'm on an old plan so it's somewhat different than what you might get. Try calling costumer service first b4 you go switching sims.

Switching the Sim card should do the trick as its already unlocked

I am not on Verizon, I use this phone for Pageplus. This probably is not a option for me.
I just went to Ireland and was able to switch the sim and use it as a gsm phone. Only issue is, unless you have it rooted, you can't change the APN, so you'll get calls and texts fine, but you won't get data at all. If you Root your phone though, then you can dl some simple APN changing app that will allow you to put in whatever custom settings for whatever carrier your new sim is with. Hope that helps.
Thanks! This is exactly what I want.
I have rooted my phone, but I will not change APN, since I only use call and text.

Hey all! Long time lurker, first time poster. Is anyone working on running the Nexus 5 on multiple networks? Specifically, Sprint and Tmobile?
I don't see why this wouldn't work right off the bat. In my head, the radios are present and sprint uses the imei number instead of a Sim card. So shouldn't it work similar to a dual Sim phone?
My hope is to keep my $30 T-Mobile plan and add FreedomPop as my source for free minutes when in a sprint area.
I'd love to hear from everyone, my searching couldn't find anything but if your googlefu is better than mine please help!
Thanks,
Matt

I never thought about this before but now that you mention it, it could be pretty cool to have access to two LTE networks if one of them is being slow. Sprint want a ICC security SIM card in the phone though, not sure if you could bypass this or use the phone without it anyway.
You need a sim card for spring LTE and voice/data on T-Mobile, and there is only one sim slot.

Thanks for the quick replies guys! I'm still very interested in it, perhaps you are right that the security Sim could be bypassed. I'd love this to gain some traction, this would be an incredibly unique feature to boast!
The phone doesn't have dual radios to even accommodate this anyway. So even if you were somehow able to activate it with a TMO SIM and on Sprint (which alone would take a ton of ROM hacking), you still physically couldn't talk to both networks. The radio would need to pick one or the other. It can't just flip flop at will, it has to set up the connection with the tower and maintain it.
I disagree. If you were to activate it on sprint, you could use it without the sprint Sim... You just would not get LTE. So technically you could activate it on Sprint (as you don't activate the phone on T-Mobile just the sim).
It would be cool if we could bypass the sprint Sim necessity.

This won't work because when connected to LTE on Sprint it uses eCSFB to fall back to 1x to accept the call. This happens over the LTE connection. If you're connected to tmobile LTE, there's no way for it to tell you you have a call incoming from Sprint's network.

So do you think it could feasibly work as a simple menu option choice, or a widget to switch networks? I personally use Google Voice so receiving calls would happen in whichever network happens to be connected

No, you actually have to switch the SIM. Once it's registered to Sprint with a SIM, then swapping that SIM for another carrier's SIM completely switches it over. Then, when you want to use Sprint again, you put your Sprint SIM back.

I guess what terky meant is he will forward calls to two numbers in Google voice settings ( let's say T-Mobile and freedompop) and then whichever network will be active will receive the call. So you will still be receiving the call.
Sounds logical but it has to be tried.
I see freedompop's website now accepts meid numbers. But my concern is; will activating the nexus 5's meid number on freedompop block using the gsm functionality of the phone??
If not, it would be just terrific!!

So with the new Android 5.1 update, which now supports dual sim, (I know guys N5 only has one sim card slot) do you think it would be easier to do this?
My idea is to get a freedompop service with the imei number, just registering the phone online and you dont physically need a sim card from them. And lets say we use another sim card ( Att, tmob, etc) to use. So basically we would have two service providers.
And from my point of view; i wouldnt need both of their services at the same time. Lets say i want to use freedompop first, and whenever it expires, I can switch to my other carrier manually.
Any thoughts on this?
Brainstorming?!?!?!
Hello!! I'm new here! I hope I'm posting this in the right place. I have a TCL 30 XE 5G (T767W) from Metro by T-Mobile and I had it sim unlocked by an eBay seller who had me hook it up to my PC via USB. The settings menu says it's still locked but it does accept sims from other carriers so I think it's unlocked. The problem is that it won't find any service at all with any sim other than the original Metro sim unless I set it to 2G only mode. Even selecting my service provider from the available network list doesn't work. The only way I can get the phone to find service is to force it to connect to 2G then change the network mode to LTE and then finally set it to 5G and that doesn't always work either and even when it does it's only a matter of time before it randomly disconnects and is left forever searching for service but never reconnecting until I set it back to 2G only mode again. All this is happening in a city with great T-Mobile coverage and all of the sims I've tried run on the T-Mobile network. The only sim that works without any fuss is the Metro sim even after the phone was unlocked. I'm using the phone on a T-Mobile MVNO now but it always disconnects sooner or later. I don't understand how a new phone can't automatically find an LTE or 5G network without first connecting to 2G and it doesn't find that either unless it's set to 2G only mode. Aside from the obvious inconvenience this causes, T-Mobile plans to shut down their 2G network soon at which point this phone won't be able to find service. Has anyone else run into this problem? I have two of these phones both are doing the same thing. Did something go wrong with the unlock? Is it a software issue? I tried asking my carrier for help but they can't figure it out either. I appreciate any help or info anyone here can offer. Sorry for the long post.
i suggest taking into a service and getting it there unlocked. perhaps your method prove faulty.
