[Q] Can Lumia 928 be used overseas ? - Windows Phone 8 Q&A, Help & Troubleshooting

Hello all- I have not found a definitive answer so will post my question here as well. I have a chance to get a Lumia 928 (Verizon) but would like to know if I can use it in New Zealand with my Vodafone SIM. I am not sure if there will be limitations such as maps, etc.. not working.
Cheers for any help, LL13- :victory:

LTE will not work in any country besides the US. Aside from that the 928 shouldn't have any issues with taking a different SIM, as all 928s are SIM unlocked when they shipped from the factory. Before you leave though, I highly recommend you download access point via sysapp pusher in the marketplace/store. Sysapp will check for any and all OEM apps that need updating.

The one warning I would give you with the 928 is that the APN settings are a little messed up, and you may need to play around with it a bit to get them to work. My experience (using the 928 on AT&T and T-Mobile in the US) is that you need to manually set the APN settings, even when Nokia Access Point says that the SIM settings are activated. You can usually get data fine, but MMS's don't work properly if you don't manually set the APN
If possible, avoid doing it with Nokia Access Point, because if you do you will lose the ability to use LTE when you get back on Verizon until you do a hard reset (you can't recover the appropriate Verizon LTE APN settings - it will only connect to CDMA 3g). Now that GDR2 is out, you can seemingly manually set the APN's in the Cellular menu of settings, so try using that first and if it fails, copy the correct APN settings into a new Access Point APN, then manually activate it. This has fixed my issue every time, but again, necessitated a hard reset / wipe of the phone to use on Verizon's LTE network.

Cheers for that information AR...
I can enter those settings manually, I've got them memorised :silly:
Cheers again, LL13- :good:

Wow very confusing topic, I mean the process of finding out whether data/mms will work outside of Verizon US, it seems it can not. Too bad as it's a beauty of a phone.

Its not that quite confusing.
LTE is only good for the country it was released in. The international LTE bandplan is different for every country, none of them match up. For using a CDMA carrier, switching to them will require a SIM (there isn't any way to flash the settings onto the phone yet for those providers who don't yet have LTE without it being official from Nokia) so its kinda a dead end.
If your going to a GSM provider, just insert your SIM and manually add the settings for data and mms. You can use Access Point if you don't intend on using Verizon's LTE.

That makes me a bit more comfortable, cheers for that information thals1992 !!
It seems that the main issue would be with the LTE which would not be a problem since I am not even sure what it is !! I believe it may have to do with 4G or fast download speeds but there is no 4G in my town anyway.
I saw one post on another forum saying that some 928's had no way to add/edit APN settings, etc...
Each post and person seems to have a different experience, but if I can simply get a 3G data connection and normal use I would be happy.
I may just go for it then.

When you travel abroad and use the phone on a GSM carrier you will get data up to HSPA+, unless the carrier happens to share Verizons LTE band. The issue with Verizon LTE after you have used another APN is that Access Point won't deactivate all the APN settings,and since Verizon doesn't have dedicated APN data settings, it doesn't override properly and connect toVZW LTE properly without a hard reset.
The 928 has a CDMA radio as well as a fully unlocked GSM radio

I have also experienced this loss of Verizon LTE after using the Nokia Access Point app and foreign SIM in Europe. Does anyone know if there is a way to get LTE back other then hard resetting the phone?

a hard reset is required as the access point app changes the LTE settings and can't change it back completely.

I can get dataconnection in sweden, and i can install the nokia app for changing APN, and i can change the APN manually too, but i cannot get MMS to work, nor in or out.
any suggestions? i talked to my carrier and they helped me with the right info, but nada.

Try limiting the connection to 3G or 2G. T-Mobile users reported this as a workaround.

[Q] "Internet Sharing" (tethering) for lumia 822

sorry for my english (using Google Translate)
lyumia 822 unlocked: GSM use the SIM card - not working "Internet Sharing" (tethering). Why? What can be done?
What's the error message? "Not working" tells us nothing much.
Also, isn't the 822 primarily a CDMA phone? I mean, yeah it has a SIM slot and apparently it supports GSM as well, but it seems odd to buy a phone that's basically a CDMA variant instead of one that's intended primarily for GSM networks.
One quick check: is your data connection working in general at all? You might have to tell it to use the GSM network instead of looking for a CDMA one.

Verizon 822 is a LTE phone, all Verizon LTE phones NEED a SIM card to run (Verizon is changing to a full SIM card model with LTE...it's about time) and it is factory unlocked (All Verizon LTE phones are SIM unlocked).
To the OP, the Verizon 822 has internet sharing disabled from the carrier, the only way to enable it is to contact Verizon on their network to use it. I know of no hacks of any type to enable it (if someone knows, let me know, I am interested too)
It seems to work fine out of box on the 928, but I have no idea if that is actually hard coded. I remember that for WP7, everyone had to download
JerryJiang's Tethering unlocker for Verizon Trophy.

I have a 928, it tells me I need to ennable it from my carrier if I want to use it. Are you using Verizon and do you have "tethering" enabled on your account or did you find a work-around for it ?
I would love to use it without paying another $20-30 a month when I only need it every once and a while.

No, unfortunately. We have their share everything plan. 20GBs of data including our HomeFusion thingy. I tried to look inside ##PST#, along with the 000000 password, but none of the fields can be changed on the 928. Any luck on yours?

By FCC law they are supposed to either use the 000000 code or 123456. Its because of one of the bands they use require this as well as all devices being carrier unlocked. It seems though they moved the settings into the sim, so the only way it might be able to be modified is through the Qualcomm boot loader which hasn't been pursued yet.

Just sharing my experience, running 8.1 on nokia lumia 822 in Guatemala with TIGO operator and was having the same issue reported on first post, internet sharing option just hanged and it did not work, today I just install access point app, made sure my TIGO APN settings were detected just by opening and seeing it, went to internet sharing and it finally worked. easier that what expected it was going to be.

[Q] HTC First on t-mobile data issue

I just received my HTC First - new, unlocked. Wifi works. Voice works well. Text works well.
However, I can't get any t-mobile data at all. Can't get on google.com.
I have seen a few thread on rooting. Will root the phone solve the data issue?
Could someone please give me some pointers? Really appreciate it.
You need to add the t mobile apn manually in the settings

I believe that T-Mobile uses different LTE bands than AT&T, so you aren't able to use the First on T-Mobile's LTE service. Either that or T-Mobile LTE isn't available where you are.

No LTE?

I apologize in advance if this has been addressed before. I'm running stock-rooted 5.0, stock kernel, and what I think(?) might be the radio for 5.0.1 I'm not sure... APN settings are correct and in the *#*#4636#*#* Phone Info menu I'm using LTE/GSM/CDMA Auto (PRL). Do I need to double check my radio or do something else? I'm on T-Mo with the TRULY Unlimited data plan. Any suggestions?

Are you sure there is no LTE. I believe come of the notification icons are finicky. In other words, on mine someone it will show extremly low service bars but does not affect my phone? or data in any noticable way. Also are you in a bad service area?
What does the top right say? Have you received lte on previous devices being in the same location where you are now?

Radio for 5.0.1 ends with .04R. Do you ever show LTE in settings, see my screenshot. I've got Verizon obviously but with TMo you should get LTE too. If you have another phone stick the sim card in it and see if you get LTE in the other phone. If not could be the sim. Could be bad signal area too. FWIW TMo LTE is band 4 and soon to come band 12.
Wow. Thanks all for responses. @vvveith I am in an excellent service area LTE for miles! @zephiK Yes I used data over LTE on my Nexus 5 just fine. @jawmail Yes my radio ends with .04R. Sadly I do not have another phone nor SIM card adaptor to try your method with. Would the newer radio make my data signal fluctuate b/w 3G, H, and LTE? I understand that this is a different phone but I swapped radios on the Nexus4/5 all the time and it never hurt anything.

1) Did you get LTE on the 5.0 Radio?
2) Try setting it to LTE/GSM auto (PRL) instead
3) When you say APN is correct. Which one are you using / looking for? Ensure it is T-Mobile 4G LTE IPv6 (if its already on IPv6 try IPv4)
If worst comes to worst, go to the T-Mobile store and get a free SIM card replacement, if they don't want to give you a free SIM. Give them a call, it'll take a couple days to arrive but T-Mo employees are quite nice about giving SIM cards. Especially since you paid for a N6 which is expensive.

1.)Yes i did and it was much more reliable.
2.)Overnight I switched b/w those two settings and kept getting the same result.
3.)I switched the APN to IPV4/6 and that seemed(?) to have solved it.
This has been going on for a couple days so I might see if I can get a new SIM.

LG G4 Sprint SIM / Network unlock

Has anyone been able to SIM / network unlock Sprint variant of LG G4? For international use? for domestic carriers?
The phone appears to be locked. I tried putting GSM micro SIM and putting phone in to GSM mode. Got an icon about invalid SIM in notification tray. But no prompt to unlock. Also no menu in settings to unlock via network like my note 3 had. Even worse, no menu to select GSM Network operator in the settings.

I know , that is the theory, I am curious if anybody actually tried it. I am concerned about the fact that I don't see a menu to select GSM network, which was there in Note 3
it almost looks like the phone can roam on GSM network using Sprint SIM, but all the menus that would allow presence of different SIM where removed.

Friend called Sprint and they unlocked his phone OTA. Now when non-sprint SIM is inserted it no longer complains about invalid SIM, however it will not connect to any networks in USA and still no way to see a list of networks or do a manual selection of network. That menu is still missing. I suspect the phone will now work outside of the USA in automatic network selection mode only, which may not be a good thing some times.

Doesn't matter what you try, you cannot use Sprint's phone on AT&T T-mobile here or any US GSM carriers. When sprint unlocks it for you, then you can use it outside of US on GSM Networks.

You must be new here. Domestic gsm has been unlocked on most modern Sprint smart phones. Just in the years I've been with Sprint ive unlocked the Moto Q, G2, S4, and now the G3 for ATT and straight talk. Ive read of several others having the same ability. The s5 can also be unlocked but only one guy knows how but you gotta pay him for it. Kinda ****ty but it actually works.

You didnt listen... Sprint phone works 100% for att.. They jt blocks it at the software level... But my friends has unlocked all the newer sprint phones till now.. I dont see why he shudnt be able to do it here
Any chances of unlocking when outside US? I got my phone from Amazon and got it shipped in my country. Tried calling them but they said they only unlock activated phones. Also tried various sites that offer unlock codes but since G4 is not asking for unlock code, they can't do anything.
Do I have any other options?
For those still trying to unlock, I've followed this post for unlocking the G3.

I can't confirm, since I don't have access to any AT&T SIM at the moment. If you're already rooted, you can try it out, but make sure to back up the files.
Another update: After updating the APN, my data finally worked. LTE is impossible at the moment since the this doesn't support the LTE bands here in my country
Warning: Don't try to disable auto activation for now. I got the Security Error and still on the process of fixing it.

SM920P Can't establish wireless data connection troubleshooting

Hi guys,
I bought a SM920P Note 5 (Sprint) in , I could use 3G at VietNam without any problems but when I arrive at Japan, I can't use 3G anymore, only ordinary phone calls and SMS. The phone keeps alerting this error : lte:esm - 29 emm - x unable to stablish a wireless data connection.
I have entered the APN setting of the carrier. I tried to put the SIM into another phone and it works without problems.
In the settings>more>about device>status : the networks says HSPDA. So I changed the Bearer in the APN setting to HSPDA but still no luck !
My OS now is Nougat, and I don't think the phone is rooted because I'm receiving auto updates.
Does anyone know how to troubleshoot this problem?
Forgive me if there were missing information, just ask me and I will provide, sorry I'm not very "technical" !

I only have 4 mode in my network mode :
- CDMA
- LTE/CDMA
- GSM/UTMS
- Automatic
If I chose CDMA or LTE/CDMA there won't be any signal at all, the working options are GSM/UTMS and Automatic which I assume is the GSM/UTMS itselft.
Any ideas ??

Did you get Sprint to unlock your phone for a different carrier before you left? Those APN settings have to be set exactly right and you must save it. Once you change your network mode it may take a bit to get signal.

I do not know if rooting it would do you any good. I am not sure if changing the firmware would allow you to change carriers. I am not even positive that's the problem. Did it ask for some kind of code after you inserted the new SIM?
Is it a data only SIM? I think it needs to be a data only SIM being a CDMA phone.

No it did not ask for any code when I inserting the SIM, the SIM is capable of Call and SMS.

No problem. I could be wrong but I am pretty sure your Sprint phone is CDMA and I am pretty sure that the only thing your phone uses your SIM card for is LTE data. So if I am correct you need a SIM that is data only. The other phone it works in, is it CDMA or GSM?

Thanks for the quick reply.
Actually I don't know anything about the CDMA or GSM things. Here is the result I got from googling the spec of the other phone :
Technology
GSM / HSPA / LTE
So, assuming you're right, can I just "disable" the calling and SMS function of the SIM, make it to become a data only SIM? I already got into a 6 month contract here, so I can't change the contract type in about 5 months !!!

You are welcome. I do not think you can do that to a SIM. The other phone sounds like a GSM phone and if the SIM works in that phone it will not work in a CDMA phone. I would go to your new carrier and ask if there is anything they can help you with. That's assuming that you are not carrier locked to Sprint. Then you have the fact that the CDMA SIM will not work in your other phone.

Thanks, but are you sure this is a CDMA Phone? Because when I change the Network Mode to CDMA or LTE/CDMA, the phone will lose all the signal?

Yes I am sure. I have seen CDMA carrier phones that were refurbished by third parties that "claim" they are unlocked for GSM carriers. I am not sure how much I trust that. You may hit up Sprint support and see if there is something they can do for you. If you bought it on contract from them they may not do anything for you.
Good luck.
