Mobile data wont activate - Galaxy S 4 Q&A, Help & Troubleshooting

Got my phone today and loving it so far except for one issue after going onto wifi for a while my mobile data will no longer kick in when switched on and with wifi switched off. Ive even tried restarting the phone multiple times but still it wont switch on. Is anyone else getting this?

Check that you have your apn set correctly in settings / more networks / mobile networks / access point names. If it's not there then add it or if it's there make sure it is selected and had the green dot on it.

Check with your carrier to see if they disabled your mobile data due to some reason.

Galaxy S2 Problems on Rogers Network - Canada

1. MMS stops working by itself, after factory reset starts working again. No settings are being changed.
2. Bluetooth connection to my car Audi Handfree is very unreliable and causes network connection to stall, no data and calls go straigh to voicemail.
3. Call waiting stoped working. Everytime i get a second call my primary call mutes and I can't hear the other person and they can't hear me. By switching back and forth between callers I am able to hear first caller again.
All of these issues are solved by factory reseting the phone.
Does anyone have a clue why is this happening?
Using latest KE7 software.
I am on rogers and are having no issues with my phone that you are having... Maybe you got a bad phone?
Can you check if your mms messaging work?

On Rogers in Southwestern Ontario. I don't use MMS, so I don't have much experience with that.
I have used by SGS2 with BT Audio and calls on an Alpine KCE-400BT (Parrot unit rebranded as Alpine) and a Sony Xplod unit without any unusual behaviour
Haven't used call waiting other than by accident, no experience there either.
Hi I'm on Rogers is Windsor, I don't use MMS or bluetooth, but I use call waiting very often and not once as it messed up on me.
Anyone using Rogers having problems with digital call display? Whenever someone calls me it comes up as "unknown" but my account has digital call display on it.
I have seen name display work fine on my phone.it's a fantastic feature!

Anyone using Rogers having any data stalling/dropping issues? It seems like every time I go into an area with no signal (subway or elevator for example) it just doesn't seem to connect back onto the network fully. Even though it will say 3G, the data connection is actually dead and I usually have to wait a while or cycle airplane mode to get it back.
I'm using the KE4 radio. If you guys are having no problems, could you tell me which ROM and radio (baseband) you're using? Also, if fast dormancy is enabled or disabled? You can check with dialing *#9900#. Also, which APN you're using for data? Is it the internet.com one or the rogers-core-appl1.apn?
Thanks
I just got a Bell SGS2 yesterday and rooted/unlocked it. I'm having 2 problems to date:
1) GPS cannot fix. I can be in view of 12 satellites, but it just won't fix.
2) My SMS timestamps are screwed up. Every message comes in with a stamp of 4 hours earlier.
Anyone else having these problems?
EDIT: Oddly enough, MMS works AND the timestamp is correct.

Hi guys, how did you get it to unlock to work on rogers? I have tried the free app on the market but that doesn't work out for me.
I have rooted the phone already.

Instead of getting the Galaxy S2 unlock app from the market, get the Galaxy_S app. It'll crash the phone at step 2, but it'll be unlocked after it reboots!

I haven't had this problem with my SGS2, but I've had it with previous Android and Windows phones. It is a known bug.
Apparently the problem isn't present when using Handcent SMS (which is really good anyways) or you can use this program designed specifically to fix the problem.

NTT works on completely different frequencies....there is no way it'd work here. If you want a phone that'd work in Japan then you'd need to buy one here and get a Softbank SIM card while in Japan.

I have checked the approriate boxes in advanced wireless setup per the help i have searched online, in fact I have checked all the boxes at one point to see if that would help

Factory reset does not change behavior
I did a factory reset of the device and this did not change the issue. Still does not remember any WIfi I have connected to once I leave the range of the wifi. Incidentally I hooked up to Kies and it would not connect to my S4 either, nor will windows allow me to access the files. the S4 shows as a location on windows but you cannot open and on Kies it just says connecting and then times out

Galaxy S5 no service

For the past week I've been having problems with network. It keeps showing No Service for a couple of minutes, and I can't receive calls/messages in the meantime. I attached a screenshot
I tried to google "Galaxy s5 no service" and there is a post on technobezz.com where they say to enter Service mode by dialing code *#*#4636#*#* but it didn't work for me
I contacted my service provider (Rogers), they reset network settings and I thought it fixed the issue as it was working fine for a couple of hours but then it started doing same thing.
Any help would be greatly appreciated!

Friends of mine were at my house over the weekend and he had a samsung s4 and had the same problem after logging onto my wifi. It is the wifi causing the problem. I had an old modem and netgear router that we hooked up and then we were able to receive calls like you should. We switched out the modem/router combo on Sat to my older setup and my phone is still working normally! I called my dsl provider and told them about the problem as I just bought the modem/router combo from them recently.
They never heard of anything like this. I do find it hard to believe that the home wifi equipment disrutes the cell phone signal. But my phone is now working!!! Anyone ever heard of this or that can explain why this would happen I would love to hear about it.
I was having the same problem and what fixed mine was going to settings>more networks>mobile networks>network operators,, once the scan finishes I had 2 networks named the same ( in my case EE) I then just tried the other EE network and up to yet its all working , hope this helps and you all get yours fixed :good:

Mobile data problem

Sadly its become apparent that something is wrong with my Yota 2, when losing the network signal when out in the sticks it will not reconnect mobile data when I'm back within decent network coverage, the voice and SMS work okay but the mobile data doesn't, even if i get full signal bars. Toggling Bluetooth and mobile data make no difference. The only cure is to turn the phone off an on then it fine until the next time.
I've checked my 3 UK APN settings and they are all as expected.
I've contacted yota support an they want me to send it to their service partner (premiere eurocom ) I have to send it at my expense and wait their diagnosis.....but I'm not sure how yota will be billed for this.
Has anyone else experienced the problem?
I'll try a factory reset before I send it, just in case...
Sent from my YD201 using XDA Free mobile app
I didn't encounter such problems so far. I was a bit worried a few days ago, as my Yotaphone kept losing the GSM connection entirely (I was back to the PIN code input screen multiple times every day), but then it also did happen on my good old Ericsson t39m, so I suspect it was more an issue with the local GSM network.
Can you try with another SIM card (maybe even another carrier) to see if this happens regardless of the carrier?
Did you change something (apps, settings...) on your phone recently? I'm asking just in case, you certainly thought about that already, so don't get offended by such a basic question!
No worries.....Thanks for the input, what network are you on?
I tried a factory reset and that didn't make any difference, that should eliminate any fiddling or dodgy apps too, I tried the Sim back in my HTC One and it behaved perfectly in there, upon returning it to the Yotaphone I lost data comm twice in a matter of hours only reaquiring after turning the device off and on. I also double checked the Three UK apn settings and they are as they should be. I could try another network as nano sim are few and far between!
I've now returned it at my own expense (Thanks Yotaphone!) To their repair partner Premiere Eurocomm, I'm not sure what will happen now as for all I know it will pass their testing in their repair labs, I'm hoping they will just send a new device .

Update......
I received a new phone under warranty, I set it all up and sadly exactly the same problem occurred. (Passing through an area of poor or no network service, the mobile data (3g or LTE) will not reconnect until the device is switched off and on again)
I now believe this is an incompatibility between Three UKs mobile data network and The Yotaphone firmware/hardware.
To crudely test this I bought a Vodafone payg sim and carried both my phones with me and these are my findings
HTC One M7 & Three UK sim......no problems.
HTC One M7 & Vodafone sim.....no problems.
Yotaphone 2 & Vodafone sim.......no problems.
Yotaphone 2 & Three UK sim....fails to reconnect.
So my options no seem to be;
Try for a refund on the device.
Change network to Vodafone.
Wait for a fix from Yota.
So I'll call the support line later today and see what they say. Could any UK users let me know what network you are on and if you have any similar problems please?
Sent from my YD201 using XDA Free mobile app
Sorry for the delayed answer...
I'm using the Orange (France) network at home without any particular issue, the troubles only happen (so far) when I'm traveling abroad, which I frequently do for work.
I'll try to list more precisely which carriers are subject to network connection issues, although it's not easy to see which carrier you're roaming with (on my old Ericsson phone, the carrier name is displayed prominently on the screen, whereas you've got to dig in the menus on an Android phone to get the carrier's name...
Okay so I called yota support an updated them and as expected they just blamed Three, so only after asking for a refund did the agent pass the problem onto Yota for more technical help, I won't hold my breath waiting for contact but if nothing by the end of next week then I will be insisting on a refund. kind of spoiled my fun this has
Sent from my YD201 using XDA Free mobile app
It would be a shame if they don't seize the opportunity to further dig into the subject and find out the technical cause. After all, they aim at a worldwide distribution of the Yotaphone 2, don't they? And it'd be a shame to see you go, too...
An update.....
I've not heard anything from Yota support but have made progress myself, I discovered in the mobile networks settings that you can select your network manually rather than automatic, by doing this two options for Three appear in the list, Three and Three UK.
I selected Three UK and since doing that the problem has not happened at all over three days of using the phone, including passing through the areas of no network coverage that would trigger the problem.
I'm hoping this is fixed.
Footnote: whilst sorting this problem I've been using my HTC One that has had its lollipop update and I'm loving the lollipop, can't wait to get it on the Yota
Sent from my YD201 using XDA Free mobile app
Any more updates? Got my phone today and got the same problem.
I got Tele 2 in Sweden and it wont connect to 4G. It will get 3G connection but very weak signal and it will disconnect and reconnect atleast once each 5 minutes.
I did also set network in manual mode and it works better but not as to expect from a phone.
Im also going to try with another carrier but im kinda locked to my current one...
On a side note, I've had twice an issue with SMS and the YotaPhone 2.
I've received the same message over and over about 50 times, usually separated by a minute, but sometimes the message shows up again only after a couple of hours...
Not a big deal, but annoying nonetheless. I suspect that the local phone network (in Congo) is to blame, but I'd be curious to know if this has already happened to anyone else, as my other phone(s) do not display such behavior. I usually have the "Welcome to XXX network" SMS repeated a couple of times, too, in those situations, though usually not more than three or four times.

Please whats their customer care mail or phone number ive been searching all over for it my phone just died as well.
I'm having exactly the same problem, I've had my phone for three days and it already happened twice. Putting the phone on airplane mode does not solve it; I have to restart the phone. I only lose data connectivity, but I get signal and I can call just fine. Btw, I'm using the YD206 version with Jazztel in Spain.
I'll try now with the manual network selection and ser if the problem dissapears.

Hello,
I have more or less the same problem ... but with no real solutions
After upgrading MM I lost the LTE signal but not all the time.
When I start my phone I have the LTE signal with good bandwith and good quality of reception.
After some time (5min, 15min, ... no really logic) or every time after driving with my car and I expect changing Emettor many time, I loose the data. I have no more LTE, H+, 3G etc... no more data and I loose a lot of quality of signal like my "modem" lost a lot of range of signal available.
I Flash and reflash MM and no solution.
When selection manually the operator, it change Nothing for me
When I change APN with a new one (2 APN are available for data (for french people SLSFR and WEBSFR)) the data is coming back but just few time.
When I come back the the first APN, data is not coming back until restarting the phone.
I have a third APN but with only 3G connection and with this one, I have no problem. Data is always available...
Really Strange. The problem is only due to LTE signal
For this moment, I will try with Lolipop if the problem don't occur anymore.

Hi Benetnath,
I find no issue with SFR.
I spoke with the customer service and they don't find any problem on the network.
I read a lot of forum and it seems that the problem is not only on Yotaphone but on lot of quite "old" phone.
They change some parameter on the network (what, I don't know, is it regarding the fact that we can travel everywhere yet in Europe using our data mobile...)
You can easyly find some post with looking about "SFR data probleme sl2sfr oneplus" through google
I expect that the problem is only on SFR but I can't be 100% sure.
Due to the problem seems to be a network "problem" or french network parameter, I think we will never have any answer or solution. It is sure that yet we will have no more update on yotaphone.
The only one solution I can give you today (avoiding changing operator ) is to use only the APN : Wapsfr
With this APN you will never be connected in 4G but only in 3G. No problem with cost or anything else (pas de risque de hors forfait) but in my case, the reception quality is really better in 4G with 800Mhz frequency that 3G in 2600MHz I believe.
Without 4G I can't receive anything inside my house.
I will keep you and the forum in touch if I find a solution.
Changing to an another operator is not so easy because for low price all the alternative operator like laposte mobile, pristel, NRJ or some other are often on SFR network with the same APN (so I suppose the same problems)
It is maybe also because SFR launched the VOLTE in June and the problem is more or less since this date.
VOLTE is maybe the problem ? When I receive a call I lose the data and she is not coming back

Hi, I have the same problem. And I think the problem go from Free : Before I had SFR and Bouygues, I never saw the problem.
Sometimes, just activate the plane mode, and desactivate it, and the LTE comming back. but another time, I have to reboot the Yota.
Hello xNiux;
With Free, I found also lot of data connection problem on Google.
The main problem with Free is that the mobile should sometime connect to a Free emettor and sometime to Orange.
So maybe your phone is not connected on the good emettor and it is the reason you lose your data connection. I can't be sure because I have not Free Mobile but it is what I wrote.
==> Maybe can you go to "choose operator" and select only Free...
For SFR it is a quite new issue, around june. Before I expected that it was a wrong ROM when I uploaded my phon to MM but it is not the reason.
Even with choosing manually the operator or use airplane mode, nothing is working. I need to restart or open/close my SIM card.
I make a "call" to the RED team to find a solution.
They wrote me this morning that now everything is fine and work well... but this morning I lose another time the connection.
For the moment :
Free is not working with Yotaphone
RED/ SFR is not working with Yotaphone
To be check with Bouygue or Orange to maybe choose an another operator ( I don't want to change my phone)
