Have to reboot after disconnected to Mobilicty to reconnect

I'm located in Toronto, Canada and recently subscribed to Mobilicity.
I recently got a T-Mobile samsung vibrant and I'm having this problem where if I lose my mobilicity connection (ie in the subway) I have to reboot the phone to get the connection back.
If I don't reboot the phone will not reconnect to mobilicity network.
Is there a network setting I need to do to get it to connect automatically whenver I get disconnected? Or maybe there's a fix for this somewhere?
The vibrant is not rooted and has stock apps right now.

I would suggest turning the radio off ( airplane mode ) and then turning it back on, this should force your phone to reconnect to mobilicity. It would be considerabbly faster and more convienent than rebooting your phone entirely... The fastest way to turn off the radio is to press and hold the power button until the power options menu pops up and hit the airplane mode selection.
Let me know if this works for you.

Thanks for your reply.
I've tried this with mixed results. Sometimes I would be able to connect to mobi's network sometimes it doesn't. If it does connect, it's only for voice and not 3G.
I've also tried manually selecting the network. It takes a minute or so to search networks and then sometimes mobi's network doesn't even appear.
Rebooting it works everytime though so there's something amiss going on here.

I tried a few things:
Coming out of subway (prolonged disconnect): The vibrant gets stuck in "Searching" mode. It does not lock into Mobi's network at even after turning on/off the airplane mode (turns off all wireless). The only way I get connected back is to power off the phone.
Coming out of basement or elevator (intermitent disconnect): I tend to lose my 3G connection when this happens. Power on/off restablishes the 3g connection. I get mixed results with the airplane mode being toggled on/off.
So right now my settings are:
- WCMDA Only in both the Mobile Network settings and the testing menu (*#*#4636#*#*)
- Manual network connection to Mobilicity
Still getting disconnects anybody with other suggestions?
thanks

Does anyone have a solution to this problem? It seems to be only happening with the mobilicty SIm card. SOMEONE HELP!!

I'm having the same problem. Is it a network problem or a phone problem? I'm using T-Mobile Galaxy S Vibrant and Mobilicity. Let me know if you guys have the solution. Thanks.

Looking for input on this as well please.

I have vibrant on mobilicity as well, had this problem on stock JFD, flashed to any froyo roms and didn't have this problem again (currently using macnut R12 + EB stock kernel)

o NICE... its all in the radio... thanx so much... i'm going to install the JK6 custom rom.... hopefully that has the fix as well...

I am actually re locating to Toronto for work so that is good to know.
Out of curisosity, I actually just purcahsed my phone and I am unlocking it at this moment. Do you know if you have to have a sim card inside the phone while inlocking? Or just after to get the key? Thanks!! I see to be having problem running the script, so I was just wondering.

Not longer seeing telus

Hi All,
Not quite sure what happened here.. Upgraded to latest nscollab yesterday, everything was working fine. Decided to try the "Antennas" app to see if it'd show where the towers are near me, switched to 2g mode, played around with it a bit, switched off 2g mode and now my phone does not see telus at all. When I go into search networks, telus simply doesn't show up and my phone stays in emergency mode.
It sees rogers fine and is able to connect to rogers with a friend's rogers sim. I've tried my telus im in other phones and it works fine, other people's telus sims in my phone don't work either.
I've tried reverting to an earlier backup as well as going back to a stock backup. I've also tried reflashing both the kb1 and kb3 radios, no luck.
Anyone know what might be the issue here?

both Telus / Bell do not have 2G
they only have 3G, as in the VOICE only works via 3G
it was the same using the SGS i9000

Did the rogers SIM work on 2G (Edge) only? I am guessing Rogers and Fido will work, but only on 2G
Same happened to me, on Fido, my phone could no longer connect to 3G...Only 2G after playing with settings. I returned the phone
The reason why Telus-Bell SIM would not work at all at this point is that they only support 3G...

That makes sense, but i don't have it set to 2g mode anymore. It should be seeing 3g just fine.

Just tried that, nothing. I think that's the same as a wipe data in recovery?
I've tried:
- Reverting back to a stock backup
- Reverting to an earlier working backup
- Doing a factory reset on both of the above
- Reflashing the radio on both

This just happened to me, I switched to 2G and got nothing but com.android.phone quit errors, now I can't get back on 3G. Flashed radios, data wipe, everything... wtf... it's back to stock now and still can't get on Telus... double wtf...

Christ... finally got it... my head hurts from all this reading
For some reason it was on the wrong band. Do this in dialer... *#*#4636#*#*, phone information, menu, select radio-band, USA, and should work make sure its on WCDMA preferred as well under phone information

I had the same issue when in Canada, and forgot I had the band set to Europe (my region).
I set it to Automatic detect, i know catching signal will take longer. But then I dont forget

i had the same problem since may 14th (sat), thanks for the fix!!!!!!!

Same thing happened here, same solution. Glad you stumbled on it too!
As the title says, had the same problem on my Nexus S (running on Bell), I believe manually switching the 2g/3g toggle in cyanogenmod rom accidentally is what set it off.
Glad you found the solution!! Was maddening for me; knew there must be a way to fix through the UI, but until I fond it, phone was a wifi mp3 player :/

[Q] Nexus 4 Radio - No 3G/HSPA Signal

I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave

have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"

Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....

i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks

participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?

Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks

I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.

solution for this
Guys....even I had the same problem.....but was able to solve it.....
Go to settings >apps>all >Google framework services in this disable it and clear data and again enable it....
Enjoy 3g once again ....it worked for me

Thank you! A few seconds after doing this my N4 connected to 3G!

I have tried what solutions were posted here but everytime I switch from 2G to 3G in the menu I lose signal on my phone..

I tried this as soon as I put WCDMA preferred I lose signal, I have tried doing this in several locations as I live in the country, tried at my school where my friends get H+ and I still lose connection. tried going back to stock still the same issue

Can someone fixed this problem? "WCDMA only" mode make my N4 lost signal.

Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks

[Q] Mobile data issue

Hey!
I have found a really weird issue since (officially) updating to lollipop (N910C, BOC3). Initially, mobile data worked fine, but after a day or two I noticed, that after going off of wifi, I only got edge connection. I rechecked the settings, restarted the phone but the phone just doesn't go past edge (to 3g or hsdpa; no lte yet for me).
So I then chose to hard reset my phone, wipe cache and reinstall everything. At first, everything went fine and I had H+ connection, no problem. I tried to enable/disable wifi and mobile data a couple of times, but all seemed fine. Today (after 1 day), I noticed again that mobile data is stuck on EDGE.
As far as I remember, everything worked fine on 4.4.4. I even rechecked my sim and settings on my old XperiaZ, where H+ works normally.
Any ideas?
Best regards and ty.
Update: After messing around, I found that by setting the network to wcdma only, allowed the phone to connect to 3g. This means that when left on automatic network mode, the phone choses 2g network and won't switch to 3g even if it is available... Do you guys know a setting where you can tell it to preferentially chose 3g, while on the auto network mode? P.S. I don't have any battery saving options turned on...

Bump... No one knows how to set preferred connection type?

Are you in a room when you are testing? Have you tried to go outside, and while you are connected to edge or H/H+ , open up your internet browser and go to a website and watch your connection if it changes to LTE or 4G...
There is an app that can do what you are asking but you have to root your device in order for it to work... I can't remeber what it's called and I know someone will chime in...

Thanks for your suggestion. I am not rooted yet and will try to keep it that way for a little while yet... will see how long i'll last xD
Manual mode will have to suffice for now, seeing as rooting is the only option. Might be a carrier setting related problem =/

LTE does not work anymore (G600K)

Hi All,
I bought this LG G6 (G600K) from HK a month ago. It was working perfectly until few days ago when the LTE stopped working. In the notification bar I can see LTE, but there is no data going through. E.g.: messenger shows "Connecting...". Basically no 4G internet any more. So I did my research and these are my findings:
If there is no LTE coverage, the phone switches to 3g and it works - so the problem is only with LTE, but LTE is everywhere nowdays
In this Korea Telecom ROM there is no way to configure to only use 3g (CDMA only), not even in hidden menu - this could be a remedy, but would not solve the issue
Wifi also works
I did Factory Reset twice (also Network settings reset), did not help
I waited for an update from KT, maybe contains a fix, but did not help
I went to my operator (TELENOR Hungary), and they have checked my subscription, and they said everything is ok, but they can see that my phone does not connect to the LTE system.
I tried my SIM in an other phone, and LTE works perfectly
So based on these facts, I can't think of other than the phone has a hardware issue. Do you have any idea how can I investigate further?
Thanks for any suggestion.

Have you made sure data roaming is turned on as you have Korean model, I had to enable data roaming to get mobile data as the device thinks that's exactly what it's doing.

Did you fix the problem yet?? I also have same situation like you.........

Hi, sorry to hear. I could not solve yet. I went to the 3rd line support of the operator, but they say everything is fine from their side. So I'm waiting for a custom ROM, or I will change my operator. If you can, send back your phone.

Well i just found temporary fix for grayed out data roaming..this method worked to me
download quickshortcutmaker from playstore open app and switch to normal search find roaming click on roaming - global roaming - create... you can enable data roaming from there..
And for manual network switch LTE /3G : quickshortcutmaker - normal view - network -networksettings global
Hope that helps
Sorry for my bad English..

Wow, thanks. This is working as a remedy. You are the hero of the day

Found the solution !
