Droid 2 Global with 3G on Rogers

Here it is. Get a unlock code and it works on Rogers network, with 3G.
Just remember to set APN first.
So it is confirmed that Verizon is not messing up the 850/1900 bands outside US.
Canadian Droid lovers, you are safe.
Btw, this phone seems to have some serious reception issues. It only shows one signal bar in my house, while other phones would get full. Hope moto could fix this via a software update.

Thanks for confirming this for us. We hear in the US are still having those problems with AT&T and T-Mobile. Hopefully we will find a workaround soon.

Thanks so much. Thats what I've been searching for. BTW, where did you get the phone? Can you just go to Verizon store and buy it outright without signing any contract, not even the month by month plan?

Got the phone from a friend in the US. What he did was activate a month to month plan, and cancel it right away.

where did you get your unlock code? can you recommend a site?

Got it on ebay. Just search for "Dorid 2 Global Unlock" and there you go.

I am following yous steps! I already asked a friend of mine to get me one. Thanks for confirming it is good on Rogers. Ebay seller is a bit greedy though - 50 bucks - ouch!

Byebyebryan, how is the battery life on Rogers (I assume you switched it to GSM/WCDMA only)? People report some horrible results like 7 hours with no use.. can't be that bad...

I'm gonna say, 1 day with some use(calls, msgs, emails, and minutes on google map). So not great, but not that bad.

Why would you have to pay for an Unlock Code? Can't you just "ROOT" the phone free?

The unlock code is so you can use non-Verizon (Vodafone) SIMs. Rooting is being able to have full read / write access to the entire phone. Rooting alone will not unlock the radio to use 3rd party SIMs.

Has anyone else noticed reception issues with this phone? I was waiting and waiting and waiting for the Milestone 2 originally and then this one came out and I want it sooooo bad. I need to upgrade from this HTC Magic but I don't want to buy a phone with hardware flaws.
I tried Googling it but all I'm finding is reception problems on the Droid 2 and the Droid X. Not a lot on the D2G but it seems like the entire Droid line has people reporting reception problems.
Is it just the number of bars showing thats a problem or do you also get frequent dropped calls?
I heard from a friend that Android 2.2 includes a new Battery Manager that reduces power to the radio when you're not making or receiving a call and that's probably why the number of bars showing is low when the phone is idle and there probably isn't really a reception problem unless calls are being dropped. Can anyone confirm this?
It's a long drive from where I am in Canada to the nearest Verizon store so I was going to make purchasing it part of a road trip to visit friends in Seattle in a couple weeks if I can get confirmation that the reception problem is not hardware related.
Any confirmations or advise would be greatly appreciated.
Thanks

Reception hasn't really been an issue for me. Seems acceptable. Battery life marginal though but I had the same issue with an HTC Desire

The funny thing is, even though the phone is showing only one signal bar, I still have great call quality and 3g speed. Wired.

Thanks guys. That was the news I was hoping to hear.

I was having problems with the 3G in France. I never got more than one bar and that was in middle of Paris

Buy it on prepaid. Its $394 plus $104 of other stuff, total 537.

I just got the Droid 2 Global and have it unlocked on the Rogers network. I can't get the 3g to work. What APN settings are you using or how did you get it to work? I have input the apn settings that are being posted around the web but can't get 3g to work. Edge works however. Thanks for your help.

APN settings are same for 3G and EDGE. Are you sure you are not forcing EDGE somewhere in settings? Or maybe battery manager?

I figured out the problem. I had the phone in "gsm only" mode. When I switched back to"Global" mode in network settings I instantly got 3g and even "H". Thanks for the help anyway

Q: I don't have data anymore

So I recently bought the girlfriend a Samsung Galaxy S 4g. Definitely a bit different than the Evo in terms of the overall process. It didn't help that I started out in the Vibrant forums somehow...
Anyway. As it stands right now I have her phone all rooted and it has CWM and I'm using the Valhalla ROM. The issue is that she doesn't have data.... and when I go into wireless networks and check out the mobile networks and such, I can never actually see T-Mobile. If I search I can see AT&T, which I connect to and I start roaming. If I do this I still don't actually have internet. I can't use the market, or the web browser or facebook or anything that requires data. The browser will sometimes redirect me to some web2go website, otherwise it just times out or says it can't connect to the server.
So does anybody know what's going on? Please let me know if you need any more details.
I've never had trouble like this between my Evo, or my Epic 4g Touch or any friends phones. I've also tried going back to 100% stock unrooted GB and I still have the exact same problem. The ROM doesn't seem to matter, neither does being rooted.

Since you are running Valhalla bring down the notification bar and make sure you have the data toggle on.

Yep, it's definitely toggled to on. I even cycle airplane mode and make sure it's on afterwards.

Only other thing I would suggest is a factory reset. The phone should be picking up the T-mobile network without any problems. But if rooted or not and on stock vs custom rom the issue remains you may just have to set it back to stock and send it in for replacement.
And I know this is a silly question but make sure you call T-mobile and verify that this line has data plan. It has happened in the past when I added a line that it wasn't provisioned correctly and out of the blue the data stopped working. The service was automatically removed due to a reps mistake.

Check your APN settings. Should be T-Mobile's, if not then that's what causing the issue. Just look up for those on google.
Sent from my SGS4G using xda forum app

My APN settings are correct. I've now tried several other APN settings though, and this hasn't helped.
I know this phone is on a data plan. It's on the $50.00 a month prepaid. It did work when we got it, and after it was rooted. I just noticed recently that it stopped working, and I'm not sure at what point it happened, and if it has anything to do with what I've done.
I called tmobile and they said they couldn't see any network related issues going on. Just my phone not connecting, so it was made a ticket for the engineers I guess haha. They are supposed to work on it, and they usually will either fix it and never contact you, or call you if they need you to do something.

Bump.
I've been in really good service areas with full bars T-Mobile and I still don't have internet. So I really don't know what's up. The "T-Mobile engineers" haven't called me back or fixed anything yet.
I'm about to bring myself back to stock and bring it in to a store.

Bring it back to stock & maybe put it in recovery mode & wipe caches & do factory reset again. See if that helps before returning it.

You might try reflashing the ROM or maybe just flash a different modem. I had issues like that once when i was on black ice. If you had data before, there probably isn't anything wrong with your phone.

Having the same Data problem
I had an unlocked ATT BB Curve on T-Mobile and the data was working (although very slow...)
I decided to try out a "Vibrant" hoping to be able to install ICS via Cyanablahblah.
Searching on Ebay I bought one only it turned out to be the 4G (it didn't realize there was a difference.)
Since then I can't get DATA on the 4G except in WiFi.
On the network it goes to the page: u.web2go.com and says my data plan does not work on this device.
Has anybody had any success with this problem ?
Could it be a 4G issue ? Before DATA came from Edge.

Have you checked what your APN settings should be with the magics of Google?

Is there any way to fool it with a 3G modem flash or something ?
I think I screwed up when I bought the phone not realizing there were 2 variants of the "Vibrant."
I wonder if I would have this problem with the earlier (non "V") 3g phone.

Probably. If it were just the 3G/4G causing the problem, you can force the SGS4G to only use 2G networks in the data settings... but if it's anything like the old Verizon bits with tethering and other data, they check for specific data strings that are harder to fake... I mean, set.

Anyone know how to force roaming on the Photon Q yet?

I have tried roam control, and it doesnt work. I have emailed them with no response yet, but wanted to know if anyone else has figured this out yet?

What does it do? For me it asks if I'm rooted when I clearly am......worked fine on gs2

it says its modifying something like it did on my epic, but nothing happens after that

Just making sure, but (a.) do you have the most current version (2.2.0), and (b.) assuming your answer is yes to the previous question, did you go into the options and choose Motorola as your Phone manufacturer?

i do have the newest version yes, and yeah i changed the manufacturer as well. thanks for the help so far

If you or anyone else figures out something to get it working please post it here. I would probably go and buy the Q finally if not for this, glad I held off this past weekend. Sprint signal is like a virtual yo-yo at work, so I pretty much have to be able to force roaming there or otherwise my battery life suffers.

By the way, I was wrong on the latest version, the newest is 2.3.0 now and was released a month ago (8/5/12)....I hadn't been to the site in awhile.

yeah thats the version i tried. i will let u know if i figure anything out

Does anyone besides whitelightnin that has the Photon Q have this same issue with Roam Control? If there are any veteran XDA members here that have a rooted Q but have never bought/used it, I'd be willing to donate the $4 via PayPal for purchase in order to help verify that this is an issue with the RC app vs. just one person's issue. It wasn't clear from donsh00tmesanta's post whether he does have a P-Q and doesn't have the problem or not, I sent him a PM to try and get a clear answer on that.
I'm anxious to get this figured out and moving forward one way or another...I really want to move to this phone but simply can't if Roam Control doesn't work.

oops, responded to wrong thread by accident:/

Has anyone else tried RC on the Q yet? Anyone? Bueller?

I have a gnex and it asks for root once but the second time it should it just asks if phone is rooted
Worked fine on ff18 and gb

Mucho thanks to arrrghhh for his time & help in verifying via a 2nd person now whether Roam Control would work or not on the Q....which unfortunately, as it stands right now it appears the answer is no.
Here's hoping MrGreg will be able to get it working for the Q eventually.

Well maybe someone else can try getting in touch with him cause he no answer me.

Just emailed him. Hope to hear back soon.

$50 donation for whoever can make it happen.
If anyone hears from Mr Gregg, or knows of anyone who can create another way to do this, I will throw in 50 bucks for a fix to have roaming only as an option, or to have roam control updated so that it works on this phone.

I also recently purchased the Photon Q and sadly, Roam Control has yet to work for me either.
Looking forward to seeing if this can be remedied.

Just happened to check the site and saw an update from MrGreg from 2 days ago (9/20):
9/20 Update: Here are the priorities for upcoming releases (thanks for being so patient)…
Support for the Sprint Galaxy S3 coming soon (within days)
Support for the HTC EVO LTE coming after that
Then support for Jelly Bean
Then hopefully updates to support new FW for Motorola phones

So it may be a bit yet, but hopefully its coming before long.

Yes, I am sharing your frustrations also! I have purchased Roam Control just to find out that it doesnt work! $5 paypal to who gets this working.

Force Roam, Sort of
Go into dialer/phone, dial *#*#4636#*#*. This sometimes does not work, so just redial it if anything. Afterwards, go into "Phone Information". On the bottom right corner if the screen, there will be the menu icon (3 squares lined up). Click on it, then choose "Select Radio Band".
3 Options will appear:
USA Band - Does not seem to work
Cellular - This will force roam onto Verizon, US Cellular, etc (all companies that utilize the 850 MHz band)
PCS - Should be Sprint Native signal for the most part. (1900 MHz, so pretty much Sprint)
Note: As of now, this should work as a decent workaround to force Roaming, however, Sprint will be deploying 1x (Voice) over the SMR spectrum, or simply put, the 800 MHz frequency. I am not sure if the phone will connect to Sprint's 800MHz frequency when available, or it if it will connect to Verizon's 850 MHz. This will not only come into play in Network Vision areas, but will eventually impact all of Sprint's network, as all towers will receive Network Vision.
WARNING: This method has proven to be problematic as you cannot return to default settings. This means no Auto Roam, you will have to manually switch between Cellular and PCS until you can use QPST as a fix. IF YOU DON'T KNOW WHAT QPST IS, DO NOT USE THIS METHOD AS IT MAY HURT YOUR EXPERIENCE.
Disclaimer: I am not responsible for your stupidity or loss of contract for using this method. I am also not responsible if you become angry at your phone and throw your cat out the window, then punch a woman out of frustration.

[Q] What is the cellular signal with the question mark next to it?

Hi all
I see a notification popping up a few times a day (on the left of my shade) with a picture of cellular bars and a question mark next to it. If I click it, it asks if I want to sign into 'home'. Since this is my first GSM phone, I wasn't sure if this was a
KitKat Issue
APN Issue
Carrier Issue
Something else
I apologize in advance if this is some commonly known GSM thing and easy to resolve, but this is new to me. I poked around on Google before posting to make sure this wasn't super obvious. Attached are two screenshots. If it helps, I have straight talk as my MVNO for ATT. Thank you all!

Is it a WiFi network named "home" that your phone has found, and is prompting you to connect to it if you can?

Nope. There are no SSID's with the name home. Also, the icon looks distinctly cellular and not WiFi (see original attachments and see if you agree)

I'm in the same boat as you -- ATT on Straight Talk, first GSM phone (Nexus 5) and I noticed this very same thing this morning too and wondered what it was about.
For me it just started today.
Hope there's someone out there that can tell us.

I'm on a T-Mobile family plan and it happens to me too all the time, I just clear the notification and nothing happens, I still have service when it comes up though.

I had a GNex & Nexus 4 on StraightTalk & I never saw that. I've had my Nexus 5 for a week & a half and I never saw it until yesterday. Now I have seen it twice in the last 24 hours. It is something new...

I just started seeing this also. FWIW I'm on Straight Talk (AT&T) also.

I'm getting it also. Straight Talk AT&T LTE SIM. Pressing the Notification takes me to google.com in chrome

I found this thread:

To sum up, several ppl were having this issue with N4 on Net10 and then Straight Talk. One guy says toggling Airplane Mode fixed it for him.
Also here:

No solution in this thread.

I also saw this one my Straight Talk LTE Nexus 5.

Interesting...
The APN I was using was an ATT one that was on my phone when I first got it. I had modified it with the ST settings.
I created a new APN and entered only the specified fields from:
http://www.straighttalkbyop.com/program.php
Then I selected this new APN as active, and deleted the old APN. Toggled Airplane Mode to reconnect to the network.
The "Sign into network" warning hasn't popped up since. I was getting it every 10 mins or so.
Update
Nevermind... As soon as I left work (and presumably changed towers) the notification was back.

It doesn't actually seem to cause any problems for me but it is weird...

I've had my N5 since Nov 4th and only started seeing this a few days ago. Never saw this with my N4 or my GNex. The N4 went to my wife after I got the N5 and she hasn't seen it happen on the N4. I just upgraded the N4 to KitKat last night and am interested to see if it starts happening. We're both on Straight Talk, though I have a LTE SIM (APN = tfdata) and she has the old one (APN = att.mvno). On another note, my daughter has an iPhone 5 (LTE SIM) which used to show "HOME" as the network. It very recently started showing "TFW", which I assume is "TracFone Wireless". The same happens if I put my SIM in the iPhone. Not sure if these things are related, but both changes occurred very recently.
EDIT: This behavior does not seem to occur when using a "real" AT&T SIM.

I'm having the same issue. Hopefully someone will post a solution soon.

For future readers of this thread, I have not received any more notifications. I did not change anything on my phone, so I assume it was an issue at the provider level (Straight Talk).

I can confirm that for me on Straight Talk this was wrong APN setting. I was missing MMS port and that was enough to trigger this warning. I believe the phone tries to check for new MMS or something and login fails without port, which triggers this message. Since I changed the APN to the same settings posted by embhorn couple of weeks ago, no question mark.

Please Help to signal problems question mark icon
Hello ... Greetings to all. I just wanted to ask a related solutions to these problems? Because at this time I experience it. I wonder what causes it, but I think this is the problem of the provider APN settings. Currently I'm using CM11 Custom ROM. But, strangely I didn't experience this problem when I was on the stock ROM. I beg enlightenment, hopefully someone can help. As seen in my post here. Because the thread for my device section nothing is peeling this problem. Thanks In Advance.
Regards.

The "?" mark sign next to signal strength signifies the SIM card has not activated yet, so you might need to register through internet(Sign in to home from notification) or talk to Customer care.

BAFFLED: no LTE, tried everything

(well, everything short of new SIM card)
The situation:
-bought a 32GB N5 from a guy
-I'm on Rogers in Canada
-on Lollipop
-cannot get LTE, only 3G and 4G (H)
-APN is correct
-checked everything in *#*#4636#*#*
-cleared cache
-reflashed facotry image
-tried Cataclysm
SOMETIMES, I'll get "LTE", but it's a phantom - there actually isn't a connection at all.
I've swapped phones many times before; never had an issue. I read in threads someone saying that on AT&T that you need to register IMEI with them to get new device working with LTE. I never had to before, but called Rogers to check if this is something they've started doing.....no.
Under device model, it doesn't say either 820 or 821. It says "Nexus 5"
I started thinking that I stupidly bought the international model off the guy, but then when i was in fastboot mode I saw that it did say 820.
So.............I'm stumped, puzzled and pissed.
Does anyone, ANYONE have suggestions or ideas? Many thanks!

Sanity check but worth investigating:
- Definitely have LTE coverage in your area? I assume other phones around you connect to same LTE network no problem
- Does the SIM connect to LTE in another known working phone?

Yep, coming from my old phone. Have always had coverage in all the areas I've been with this new phone. LTE SIM, LTE area...it SHOULD work, but is not.

Try a new sim at the store, if it doesn't work return it on the spot. No harm, worth a try

Does 3g work? What bands does your carrier run in your area? You might try the diag LTE screen (requires root, there's an app from the Play Store) and see what band it sees. Also have you tried doing a scan of which carriers are available?

3G and 4G work.
I went to Rogers store and got a new SIM. No change.

Same thing...
I'm just posting to let you know I've had EXACTLY the same problem..
Mine occurred after I smashed the screen and sent it away to a company to be repaired. My N5 came back with a new screen, so immediately I upgraded to lollipop...
Then the LTE stopped working. Occasionally the device would say it was connected to 4G but, like you, it didn't work when it showed this. I tried everything, flashing, checking access points, flashing different radios...but nothing worked.
Now I can't work out if the repair company had somehow damaged the 4G antenna when they were fixing the screen. So I sent it back to be repaired (again)
Now i've got it back. 4G works but it has lost a lot of speed. Where I was getting 25mb/sec on average, I now get 10 max.
I've e-mailed the repair centre to find out what they did, but honestly, I've given up a bit now...

Wait, you upgraded to Lollipop? You realize that they included a new radio right? Try reverting modems.
