[Q] Galaxy Nexus i9250M Not working with Mobilicity

Hey I just picked up the GN i9250M (bell) and inserted my mobilicity sim but it says it cant connect to the network. Im assuming this is because I need to unlock the phone. Is that correct?
If that is correct to unlock the phone I need the SDK files and grabboot? can someone direct me to a tutorial on this?

What is the exact error message? You don't see any signal bars at all or is it just when you try to use data? The phone should be unlocked already. Most likely it's the data that can't connect, check your APN settings.

the error message was "cannot connect to the network at this time please try again later"
thanks for the quick response and sorry for wasting everyones time...not sure why this happened but once i walked into my house it connected..possibly just out of coverage area. up/down links seem to be working fine and calls can be made so im happy.

actually im having another issue now..dont know if i can ask it in this thread but whenever i try to download something frm the market i get a cannot download due to an error message...any ideas?
thanks again

Wifi or network? There are posts that say you should go to your APN settings and delete the proxy so that it's empty.

that was my first troubleshooting step but oddly enough the issue is only intermittent with wifi...some apps dl some dont, same issue now occur on network

hmm issue seems to be isolated to network connection now...what was the apn thing you mentioned?
can also confirm that connection is active and functional; browser and other apps working fine

In Settings -> click more under wireless & Networks -> Mobile Networks -> Access Point Names
You should see one or two APNs. click on them and make sure that Proxy is blank or "not set"

Bell runs an HSPDA network and Mobilicity runs an AWS network. You cant use the phone on Mobilicity's network.

Yes, you can use it. It will work fine. SGN is pentaband and unlocked. Just make sure your APNs are correct.

Sorry, I was going off the specs at GSMArena (which are wrong more often than right nowadays)

I just got the same exact phone.
Go remove the proxy address in the APN settings. and the reason it didn't connect at first because the phone was trying to "learn" how to connect to the Mobilicity. network.
I thought my phone was defective as well until I waited a bit after. It's a beautiful device

I ripped these from mobilicitys support section of their site and copied and pasted them verbose. I've yet to procure my GN to test them with so any modifications or sugguestions are welcome.
mobilicity apn
STEP 1: Go to Settings > Wireless & Network > Mobile Network >Access Point Names
STEP 2: Press the ‘Menu’ button and then select create ‘New APN’
STEP 3: Populate the following fields:

Proxy: 10.100.3.4
Port: 8080

APN type: default
STEP 4: Save
Please note: Other fields can be left blank
To create an APN for MMS
STEP 1: Go to Settings > Wireless & Network > Mobile Network >Access Point Names
STEP 2: Press the ‘Menu’ button and then select create ‘New APN’
STEP 3: Populate the following fields:

May be a long post!
I heard that port you can just leave Blank instead of 8080...speed increase so they say!
1. Set APNs>> posted by android01 (I have heard if you leave port blank you get faster speeds, just heard)
2. Go to setting and Disable Roaming as to not incure extra charges...
3. This is a somewhat of a Backdoor fix i found that worked with Samsung Vibrant from T-mobile... DISCLAIMER: USE AT OWN RISK! ONLY MODIFY THE SETTINGS LISTED.
IF the setting is not as listed, Read the setting heading click the matching section heading, to find the location of this setting scan and read all of the setting heading/titles.
If is works without a hitch than great....Let me know.
Again these directions i found on Howard Forumns and worked with a T-Mobile Galaxy S Vibrant
I had copied this into a Word document for my Mum as the phone was going to her:

It works!!! It totally works!!!! I love it! Thank you so much guys!!!! Now I don't have to restart my phone EVERY morning as soon as I pull out of the underground garage in my car!!!
Thank you, Thank you, THANK YOU!!!!!!
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands[*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Your phone should now be locked into 3g.
__________
Also what i do is Only click the 1700 and 2100 frequencies.Chose by hitting the menu button>>back and i forgot the option. it is "to add another band?" and so click either one frequency first, then menu>back>"add another band"!
This keeps me on 3G directly and always!!! DONT forget to turn Roaming off as to not incure unwanted charges.
Hope this helps and let it be known if it works for you nexus guys. or am i full of it and these are samsung commands....DOH! if they are.

the nexus from bell does not have phone lock..
i can use my fido sim in the phone..my nexus is from bell as well

Yep I have it with Mobilicity and it is an absolutely great phone granted some things are slower than they would be on 1 of the big 3 but it is more than adequate

actually for the price you pay its the best plan for GTA. i mean data isn't the best but good enough for mail, browsing and checking score.

turning off lte

i know there isnt a toggle for turning of lte on the at&t variant but i thought there was some work arounds to this. can someone please post the steps to do this?

There's fairly simple instruction for this not only on xda, but on multiple other sites as well. Have you heard of Google?

In short - change APN settings.

actually theres a better way, if you're on CM10 or AOKP dial *#*#4636#*#* and choose WCDMA only or WCDMA Preferred. This will prevent the phone from trying to use LTE as its default network.

It doesnt if you're on AOKP at least for my ATT it doesnt, if I set it to WCDMA preferred as it is by default I never see LTE, even with the PTA APN selected, and I know LTE is active in my area because on stock and CM10 I default to it and get upwards of 30-40 Mbps

See here:
http://forum.xda-developers.com/showthread.php?t=1826409

Theres also a way if you have root to create the new APN and have it stick (reason it doesnt stick is because PTA is set as default and because you cant change it reverts back to PTA). I'll give the steps I took to allow me to edit my PTA APN. again remember you need root. (also sqlite)
1. Using root explorer (or similar) navigate to /data/data/com.android.providers.telephony>databases>nwk_info.db
2. Tap on Carriers
3. Select line for AT&T PTA 310/410 scroll all the way to the right and under editable put a 1
4. Do the same for ATT Entitlement
5. Go to the PTA APN Menu>Settings>More Settings>Mobile Network> Access Point Names
6. In the PTA APN delete the values in the "APN type" field (this will prevent the phone from defaulting back to this APN)
7. Create new APN

Only down side to this is that the phone will periodically drop ALL signal but then gains it back withing 15-20 seconds. I'm also still looking for a way to enable the "Network operators" selection through root explorer (I imagine it to be in a similar place as the APN settings). Any help from someone more knowledgeable than me is appreciated. Hope this helps. Also below is a link to where I posted working USSD (MMI) codes that I found. Maybe something can be discovered in those.

Where are APN settings in JellyBean?

Am I blind or did they vanish? I go to SETTINGS --> MORE --> MOBILE NETWORKS, and I have 4 options... Data Enabled, Data Roaming, Network Mode, and System Select. Isn't this where one previously would have found APN settings? Are they somewhere else now? I've searched like hell and haven't found any mention of them being moved.

Aren't APN's a GSM thing? I'm not sure if you'll see that on a VZW CDMA device. On that screen on my GSM phone I also have Access Point Names

Well that would explain it. Why am I thinking you had to add APN info for MMS on a Verizon device though? Perhaps I'm confusing myself.

Open Voice Dialer and say "open apn settings" and bam, your in. And us CDMA users do have and use these settings for adding MMS settings if necessary.

Another VZW GNexer here. I absolutely cannot send MMS any more. Tried using voice to access the old apn settings menu, no luck. I can manually go into /system/etc/apns-conf.xml or /system/build.prop without issue and can access all apn-related text, but am not quite sure how to go about tackling the problem from there (wouldn't want to change the wrong setting).
I've done a bit of searching, and haven't quite found a solution that works for me on 4.2.1...
***Update***
Turns out, the issue was related to Handcent. No apn editing required. Go figure...

My phone doesnt take a sim

[Q] Phone won't roam-settings are missing

Hello everyone,
I have a new AT&T plan with five lines, all using Samsung Galaxy S3s, all having the same problem. My 14 day grace period to cancel is almost up and I'm at my wits end searching for an answer. The phones are not rooted as I do not understand most of this technology; however I'm smart enough to know that this is a problem beyond rebooting the phone or resetting the SIM card, as every forum out there is telling people to do. Calling tech support (please don't make me) is a LAST resort for any device I own.
In the town where I work and shop I have no signal at all from AT&T. No voice, text, or data. AT&T coverage map shows "good" coverage in this town. Every so often I do get a weak AT&T signal but only for a few seconds. I do however pick up a very strong signal from a T-Mobile tower. I know that AT&T and T-Mobile both use GSM and should be compatible for roaming purposes, but the phone does not roam; it just shows a strong signal that I cannot connect to. Also, it switches back and forth between these two towers. I posted screen shots taken one minute apart.
In my phone's "Mobile Networks" settings there is no option to chose a network. There are only four options on that page: Mobile Data (checked), Data Roaming (not checked), APN, and Network Operators. I have tried adding a new APN but that did not work. The Network Operators tab says "Default Setup" and I cannot change it. I understand this is an issue with AT&T - they deliberately remove these settings.
I have gone through all the settings in Service Mode using *#197328640# looking for a way to enable the missing settings. I have already used the Service Mode to disable LTE (another setting AT&T likes to deprive us of) but that was not the problem so I put that back on automatic. I have also checked and unchecked every imaginable combo of settings such as wifi, data, airplane mode, etc.
I think the problem is either that the T-Mobile tower is interfering with what *should* be a good AT&T signal, or that the fact that I am "connected" to AT&T (albeit with no bars) is preventing me from roaming. I'd like to know if there is a way to disconnect from AT&T to test that theory. Also, I'd like to know if there is something I can do from Service Mode to enable the missing settings so I can set up roaming.
Thanks so much for any suggestions or help.

What APN(s) are currently listed?

Just the default one called "ATT Phone".
I tried a Cingular APN in order to get a better connection to the AT&T tower, but it didn't work and I removed it. I found the T-Mobile APN info and was planning to try that next time I'm in town if I don't find some other solution first.

Is it the wap.cingular or pta one? You have to reboot after changing apn's but I'm sure you already knew that

I used the wap.cingular one and did reboot. Do you think this is an APN issue? I'm kind of at a dead end unless I find where to enable those mobile network settings. Thanks for your responses.

Unfortunately, it didn't work. I also tried to use a T-Mobile one and the phone wouldn't even let me save it.
I broke down and called AT&T tech support to find out where the roaming settings are in the phone... of course they didn't tell me, but they did tell me they don't have a roaming partnership with T-Mobile in my area. Therefore I'm out of luck and will be cancelling my contract.

Questions re Network/APN (and also #*#*4636*=*#) for best LTE, VoLTE, or nearest ther

Hi..
I bought an unlocked HTC 10 from HTC a few months ago. My carrier is TMOUS. I have read a few places around XDA and Reddit that the HTC SIM-unlocked phones on TMOUS experience erratic signal strength and/or coverage for voice, data, MMS, etc. at times.
ThinKing I might investigate this by looking at the APN settings, I checked my phone to examine the the specifics of my APN configuration, and I noticed several items that were missing from most of the "2016 TMO APN Settings" found around the web. Specifically, the settings under MMSC and APN Type seemed to be incomplete or incorrect.
After changing some settings of the APN settings above, and also going into "#*#*4636*#*#" under "Phone Information" and changing more, I lost all data and voice for a few minutes. I simply rebooted to get those original settings back, butreboot and get things back but now I would really like to know what the settings those T-Mobile customers who purchased their HTC 10s from TMO before they abandoned their sale of them. I also would be interested in anyone suggestions on how I might keep new settings if a reboot just restores the original settings.
Specifically (as far as settings) I am curious as to the settings they have for their main APN, and also what is set for "Set Preferred Network Type" under the menu/settings when "#*#*4636*#*#" is typed and you go into "phone information". The correct setting is a list of protocols. I have checked around the web and cannot seem to select the right list of protocols on this phone, so I am really puzzled as to the right setting.
Ant help would be appreciated...!

download the tmobile app. in the app, you can run some diagnostics and one of the tests will tell you if your APN info needs an update and you can update it from there. its all very easy, just download the app and run the tests.

Thank you! The list of things after APN Type is great...All I had was "default,supl"! Also thank you for that "Set Preferred Network" of GSM, WCDMA, LTE (Auto).
However, what's really strange is that I don't have an option for "APN Protocol" nor "APN Roaming Protocol"...so i can't specify the IP protocol.
I was hoping to enter IP protocol because I read that T-Mobile now has IPv6 up and running.... soooo if you change "APN Protocol" to IPv6, you should experience a better signal as IPv6 is probably only being used as overflow right now.
Try it (if you want) and let me know if you experience any difference.
EDIT: One more question..under Settings-> Mobile Data -> Preferred Network"?
I have two choices: Global or GSM/WCDMA/LTE. Right now I have global selected, but don't know which one is correct. What is yours set to?

I installed the one just called T-Mobile and it said "T-Mobile is hitting some rough waters and isn't available right now", so it may not like the fact that I am rooted, S-off, etc. But I'm not sure....

Just convert it to T-Mobile then flash a custom rom with with carrier options in aroma installer. Choose T-Mobile and your good to go.
One thing you must do first is s-off via sunshine.

I'm s-off already, so I'm good to go...But what do you mean convert to T-Mobile? When I got this phone and put my T-mobile SIM card in, and started it for the first time, it pre-selected T-Mobile network and took a few minutes to configure (and presumably the correct bands and frequencies) automatically.
When I go into "Select Network operator" only T-Mobile and AT&T are working choices...and T-Mobile has a start next to it likely indicating it's the proper network for this phone.
So I think it's already a "T-Mobile" phone.

change cid to T-Mobile cid and flash ruu. Then you will have T-Mobile radio. When Android N comes it should be fixed on us unlocked versions. I have 2 10s and ones on T-Mobile and other us unlocked and on us unlocked band 12 is unstable where I'm at so I get all the problems you described.

Thank you... Do you think it would be possible to just change the CID and create a SDcard zip file with TMO firmware. In the past (with my HTC M8) I have extracted the components from a stock ROM.zip (which I got from an RUU) and created a firmware zip which simply updated my firmware and didn't wipe internal storage flash stock recovery, etc, etc....
I guess my question is...provided I create the bootable external SD firmware.zip correctly and also change the CID, is this a feasible plan?

yes it may be possible but I'm pretty sure data is going to need to be wiped. When I used the firmware zip method to convert to T-Mobile my data wouldn't work without doing the ruu first then waiting till it booted fully first. Then proceeded to install twrp and custom rom. So if you end up with data problems then you must ruu.
I have the latest ruu for T-Mobile I just haven't uploaded it yet. If you need it let me know.

Uploading the latest RUU would be amazingly helpful!!
One of the reasons I am hesitant to RUU this phone is because I'm on the HTC build 1.96.617.2 (and an OTA waiting if I want to install it manually), but the TMO RUU I found in this forum is 1.80.xxx...which I believe is from last June. I didn't really want to go back to that older build...
EDIT: I was going to change my CID, but just realized I have no idea what the T-Mobile CID or MID actually are. Could you possibly do a "getvar all" (or if you already know it). I searched around for it but only found HTC CIDs and obviously SuperCID.
