I want to buy my cousin a G1 and send it to Sweden, will he be able to use DATA? Or will it just be the phone and sms?
Thanks in advance.

Yes since it's a quad-band GSM and dual band, WCDMA band I (Europe/Asia) & band IV (T-Mobile US).
You just have to be sure that the phone is unlocked and your cousin knows the local access point (APN) so he could enter it.

Yes you can add APN and delete existing APN on the phone.
I can confirm it works great on Telia in Sweden
activation?
How about activation? I saw lots of post claiming that you need to use a t-mobile SIM first to "activate" the phone to be able to get access the android os, settings etc?
Does it work with Android Market and all with Telia?
Nothing to worry about activation.
Just unlock , you will be able to use it without any problem.

It helps you activate your T-Mobile G1. Have added settings with PICS.

Activation problem
Hi i bought this phone on ebay and im having problems activating it
the phone is unlocked but when i stick the vodafone sim(Ireland) into the phone i cant
activate it .
I've tried using a t moblile sim card(USA) but there are no network coverage in Ireland .
I will try to use a T mobile sim card from the Uk but im really worried at this stage
Does anybody have any suggestions ?
what activation do you mean ? Does the phone ask you for google account userid and pass ?
exactly , but i cant log in to my google account because the vodafone apn settings wont work on my phone
you have to insert the settings from your provider. if you have vodafone and it doesnt work, try again I had to try 3-4 times to find exactly the correct settings (port,servers, a.o.). Im sure it will work with the correct settings (assuming that you have an google account).
I will try but i cant get the correct settings for this phone since vodafone doesnt support G1
Did u get it working on a diferent network ?
no problem if you dont have 3g ! I had only gprs / edge when I did activation and it worked here in Switzerland...
I have did it for Boxed Packed tmobile into airtel india.
You Definately Require Sim Unlocked code from
http://Unlock-TMobileG1.com the same site i got the Unlock code @ $23
They have also Provided me the Full Manual to add You Network APN Setting
MNC / MCC Code then used airtel SIm got that E icon on top with Signal Bar used Gmail A/c User name and password and did it.
No he doesnt need ! his problem is not the unlock code, his phone is unlocked as he wrote above !
He just has to find the correct settings for the APN !
AlrightThanks for helping

Hi
I have a HTC Diamond and want to unlock it to use on 3 network.
I know unlocking works with T-Mobile, O2 & other SIMs but does it work on 3 network & still give me full web access, email, etc?
I what to change to 3 network as the Orange 3G in my area (Redcar, UK) is useless even thought their coverage map said very good (before I bought).
I've spoke to Orange's customer services & they told me that 3G is 'Limited' in my area but I know my brother has 3 network and gets 3.5G in this area.
Anyway enough of me moaning about Orange can anyone help with the query?
Thanks people
Yes you can mate, I'm doing exactly the sane thing I bought an unlocked orange Diamond and stuck my three SIM in. No problems!!
Thanks for the speedy info
I'll get it unlocked and post how i get on
Thanks

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

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

Hello Guys !
I got a sprint ativ s neo which I now intend to gift to a cousin who lives in India as I'm not using it anymore. Before buying I checked and confirmed that it has both gsm and cdma radios as well as settings which would allow to choose network mode when not using sprint.
However there is an issue. While u have a sprint sim inside the phone u have the option to choose network mode enabled, however if u try to put in any other international sim (gsm or cdma) it will disable that option and has CDMA selected by default. Now I cant change the mode and it doesnt allow me to use the international sim ( although it detects the sim as I see network signal as well as sim applications pop up).
Can any of you guys help me figure out what else I can do to make it work on international gsm provider or even cdma providers ?
Thanks in advance

US carriers are required to offer you the option for unlocking your phone. Most likely you will have to own it outright.
Please check here for sprint's policy: http://www.sprint.com/legal/unlocking_policy.html
I got Sprint to give me the code, but not sure where to put it...
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.

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.

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 :

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 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?

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.

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.
