[Q] Unlocked Captivate can't see/register on Bell network

I just acquired an unlocked AT&T Captivate.
When I put my Bell Canada sim in I can not see/register/connect to the the Bell Network.
If I put my wife's Roger's sim it connects right away and when I enter the Rogers APN info it connects fine to the 3G network.
With the Bell sim in there I cannot even get to the menu for automatically or manually selecting the network as the meni option is grayed out/unselectable.
Any ideas? Are there other Bell Captivate users out there?
edit: with the Rogers sim in there and if I manually search for a network it list Rogers and a 302610 network which suspect is the Bell network as the MCC is 302 and MNC 610 for Bell

maybe video? i wanna see it
is the sim itself ok?

My cap runs fine on bell... I have the network selection part greyed out too but it picks up signal as soon as the sim is in place
Sent from my X10i using XDA App

I am assuming the SIM is fine. It works in an unlocked Telus Hero and an unlocked Rogers Magic. What video would be helpful? Of the settings screen or the no signal icon in my notification bar?
I get no errors or warnings with my Bell sim in there. It just won't find the network.
(and thanks for confirming that there is at least one other cap working on Bell)
My plan is to get Froyo on here anyway. Is changing the ROM or Kernal likely to impact this issue at all?

which band does bell use? which modem you use? (euro or us?)

Bell uses 850 & 1900 - my understanding is that they are same as the Rogers frequencies.
I am assuming I am using a US modem. How do I check the modem? The phone is an AT&T phone that did arrive in my hands rooted and unlocked already so I suppose something else could have been done to it.

more details:
Baseband version: I897UCJH7
Kernel version: 2.6.29 [email protected] #2
build number: ECLAIR.UCJH7

Anyone? I've tried different modems and ROMs including the Bell i9000 modem/rom for the Captivate. Its almost like my sim is bad but I know it works in my htc magic.

well in case some one else has this problem it was the SIM. Apparently there is a problem with a batch of Bell SIMs - they had me swap to a new SIM and I connected immediately.
Woo Hoo!

[Q] Does Nexus S work in Canada on Fido network?

I was using my nexus s on Rogers network, and I thought, that since Fido is basically the same company as Rogers and Nexus S is an unlocked phone, my nexus s should have no problem working on Fido's network, and all I have to do is changing the SIM card.
The truth turned out to be, my nexus s, with a Fido SIM card inside, is ROAMing on Rogers network! I cannot see any carrier but Rogers if I go into the "network search" menu! Even if I checked the "only use 2g network" option!
I live in Montreal and I should have perfect Fido reception. My guess is that my nexus s may be secretly locked to Rogers network, and no matter what SIM card I put in it always, and only, finds Rogers network and connects to it, making the service become roaming if i use SIM card from other local carrier.
Is there any nexus s using Fido's network properly in Canada? or specifically in Montreal area?
Has anyone found a problem like this when doing a network switch?

it will work only as Voice
data will be EDGE only

Its currently asw 1700 / "t-mobile" only' therefore wind or mobilicity will get 3G.
Rogers Fido Bell & Telus use HSPA 850 1900 will not.

Is your phone *really* roaming on Rogers?
Fido is owned by Rogers, and as far as I know, they share the same network.
It could be that your Nexus S is just not displaying the network name "FIDO" and is displaying Rogers instead.
Wind Mobile, for instance, displays their network number on the Nexus S, but if you put the same chip on a Blackberry it will either show "Wind Home" or "Wind Away".

Yes. My Nexus S works fine with rogers. If I switch to a Fiso SIM card, it literally ROAMs on rogers network with a little "R" on top of the signal bar and ONLY finds rogers network in the "wireless" menu.
This is so weird.

It finds Rogers network and connects to it in EDGE. Even Fido and rogers use the same network/frequency/towers, it just can't see any network but Rogers.
Are your phones working well with Fido?

it doesn't matter, it still is on FIDO
i had an old Treo phones that did the exact same thing, because FIDO is not considered a real network in Canada as it's owned by ROGERS, so most of the time they get grouped together
but if you see their tower ID, you'll see they are on the correct tower
but it is a very tedious process to do that
regardless you will not get billed roaming as fido=rogers=fido=rogers=one company with 2 faces

My friend and I are both on Fido. We have older basic phones. I am on a basic plan. He is on older CityFido plan. Neither of us have data plan, voice only. His phone shows Rogers. Mine shows Fido (perhaps due to my SIM).
When I look at available networks in my phone, I only see Rogers. Fido no longer exists as a network. It is merely a cosmetic sub-brand of Rogers.
Fido and Rogers merged networks years ago; there is only one network: Rogers.
I hope this helps.

not getting a signal abroad

I am currently in Japan with my htc inspire and I am not getting any signal at all. I tried resetting and going into the settings menu to change the "network operator" but its greyed out.
does anyone know what I am doing wrong? I desperately need it to work here and I have the international plan activated on my account.

Well in Japan you wont get 3g due to Japan using 2100mhz and The Inspire does not have that freq built in. You should get a call signal. Make sure you enable international roaming on your account. Or if your phone is unlocked buy a local sim card and pop it in.

I enabled international roaming on my account and have the $6 plan added for cheaper international roaming service.
I don't need 3g, just a phone signal to make calls and receive texts. but all I get is a "x |on top.
I have travelled to countless countries with my other unlocked phones and have never had a problem with my phone not picking up a signal.
is it possible that because I changed to a 3g sim card, it doesn't work abroad?

japan does not have gsm EDGE coverage i dont believe. they do have 3G HSDPA, but on 2100mHz, which the inspire does not have. so you are kinda out of luck i'm afraid.

Verified with AT&T's tool here
http://www.wireless.att.com/travelguide/coverage/roaming/step1.jsp
The Inspire doesn't get voice or data in Japan

Had the same problem in Korea last week - sucked big time. How can they call it a world phone and leave out 2100!!!!

That is absolutely terrible and false advertising since Japan and Korea re left out which are huge territories. I also have an unlocked samsung vibrant that I need to charge to see if it works.
Does anyone know if the vibrant has the right frequencies for Japan?

According to the same tool I previously posted, the Captivate will work in Japan and South Korea
Edit: Oh, Vibrant... hold on
Don't know about the Vibrant, does it have the 2100 frequency? If so, then probably yes

Yeah I still can't believe this phone left out the 2100 frequency. I posted about this a few weeks ago and still can't believe I didn't notice that it didn't have the 2100 when I bought it, as I travel to Japan quite often.
I don't like the Atrix and the Infuse 4G isn't out yet so I'm just waiting it out until some better phones come out and will just use a older phone in the interim. Those both support 2100 apparently. Kind of ridiculous that HTC left it out of this phone.
Just did a quick search and it looks like the Vibrant does have 2100 UMTS support.
Sprint CDMA works in Tokyo (and possibly Verizon). Not sure what carrier it uses but it does work for voice only. Probably not much help though.

Verizon M8 only connecting to 2G/GSM networks. No 3G/4G.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!

Same problem

Anyone can provide any help on this??

do you know the actual bands/frequency the gsm network uses where you are? the prl is going to be pulled from your sim card. have you also tried a diff sim card?

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.

so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

hmm this is quite the problem. if you can confirm you are using the same rom as the others, i would then think the issue is the radio being defective

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios

T-Mobile LTE in US isn't working...ideas?

I imported the 8141 from Clove in the UK. So far, my only real issue is I have yet to see it connect to LTE. I've seen "4G" and "4G+", but no LTE...which is a problem because I can barely pick up a signal other than LTE in my area. I checked and confirmed it's using the correct APN (fast.t-mobile.com). I'm on the 110/unlimited/unlimited $30/month prepaid plan and confirmed I haven't hit the LTE cap. If I put the SIM back in my Moto X Pure/Play, it hops on LTE without a problem.
Everything I've read says the radio should support T-Mobile's frequencies. Is there another setting somewhere I need to change? Do I need to flash another region's stock ROM (and is that even possible yet)? Did I get a lemon? Do I need to hold it a certain way like whatever iPhone it was a couple years back?
Any and all suggestions are welcome.

4G+ is the UK's LTE as far as iconography is concerned. Have you done a speediest on 4G+?

I've noticed the same thing, but I (as mentioned above) thought that LTE and 4G+ were synonymous. I think the only reason to flash a region based image would be to enable radio bands that are disabled based on location (which may be in this case).

Works fine here. Lower Manhattan using same version.
4G is LTE in US.

Download LTE Discovery and you'll be able to see if it is connected to LTE or HSPA(+). Mine, also from Clove, is just fine with AT&T LTE.

You are looking at the signals wront, I'm on T-Mobile and have 4G+ as well it's the UK version of LTE. Look at my screenshot.

4G is basically the same thing as LTE in this case. 4G includes WiMax and LTE. So when you see "4G" it means you're using LTE. The same goes with 4G+ - LTE-Advanced (LTE+).
I have LTE logo on my Z3 while Z5 Premium shows 4G while using the same network.

4G is LTE in europe. We did not have that silliness that some 3,5G was called 4g. Also there is no band limitations on XZ Premium.
For app to check which band of spectrum you are connected to, please use Cellmapper app (from my signature).
If you wish to see different icon in there, you could flash Customized DE firmware which has "LTE" icon. But this has only cosmetic effect.

Instead of making a new thread, anyone knows if VoLTE works with the XZ Premium for T-Mobile?

Currently no. You need region or operator specific image Flashed (oem.sin) but there is none for XZ Premium.
But there is hope as there is t-mobile us specific modem configuration in all region images.. which will be loaded when you have correct oem image Flashed.
