Data connection isn't starting

Hi. I just bought a new galaxy s from vodafone, but when i tried to use a 3g data connection it just won't work. it works fine with wi-fi connection but if i turn that off (or if i don't use it at all) the phone just won't connect to the internet. i've double checked the apn settings...is there an option to turn the data connection on and i'm just not seeing it? please help...

sometimes it helps to restart the phone
or switch it to airplane mode then back

Did that
i've read other posts for other type of connection problems and i did what u said...nothing...it just doesn't even try to connect...

do you have any other SIM card from friends/family that you can try?
just wondering if it's related to your SIM account, or if it's defective phone

if it is working over wifi there is still something wrong with apn settings or your sim card.. i doubt it is the phone itself.. or you are in an area with no 3g edge.. or wrong phone ie t mobile vibrant on bell or att network

thanks for the update
glad to hear you are back online
yes phone companies do mess up very often in our accounts
just yesterday i was complaining to my phone company about something similar

[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP

did you install DroidWall ?

Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?

Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.
Anup

Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

The problem is that I'm not from Czech Republic. The phone was purchased there by a friend of mine and brought to me...

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.

as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.

Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks

Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

Pair 10 pro with AT&T Number Sync successful

So sorry if this was common knowledge but I haven't seen anything on this yet so I thought I'd share. I decided to try setting up AT&T's number sync between my new mate 10 pro and my LG Sport and it worked. What makes that amazing is this is the first non att branded phone I have ever been able to set up directly between the phone and a att smartwatch that didn't require me using a att branded smartphone in the middle. You can't find the ability to do it through the my att app or website but if you initiate through the watch, it will open the browser on your phone and then give you a number sync code, once you log in through the browser, you put in the code and then accept terms and it will successfully link. This phone also seems to work well with the LG Sport. Battery life is waaay better then when it's paired to my Att Note 8.
FYI, Att number sync allows multiple devices to receive a phone call or text message from the main line they are tied to. That way every thing is seen from one number. One of the requirements is that the phone must be Att branded.
So that tells me between this and VoLTE working on att with this phone, this phone was all but ready for att network and only thing missing was the att branding on the phone before att backed out.
Sorry if long l, just wanted to share to maybe help other att users.

Have you been able to get/verify that VoLTE is working on your mate 10 Pro? If yes, how did you verify it works? I have a Dual Sim 10 Pro rebranded to the US 10 Pro (did at Best Buy) with the Enhanced Voice and VoLTE options enabled. Thanks.

I didn't use the default apn that sets up when I had my att sim inserted. I used the settings from att's support page: https://www.att.com/esupport/article.html#!/wireless/KM1218306
If I remember, there were a few subtle differences. Honestly, I didn't notice if VoLTE was working before the new apn settings but I see that it works for sure with the new apn settings. My status doesn't change from LTE whether on call and/or browsing.

No problem. I was thinking, you said you rebranded to us but I wonder if by a slim chance there is some hardware difference that is dectected? Like maybe a certain band att uses. I haven't looked at the differenceces in bands between models.

Cellular bands are the same as US version; when not in a call I connect to LTE+. I can achieve cellular download speeds of 98 Mbps. Main difference between US version and mine is my phone is dual SIM Mate 10 Pro. The second SIM connects to 4G when I make a call. If I use only 1 SIM, connection drops to HSPA+. I see an option to enable VoLTE on the second SIM, but it's disabled. Have you to find a way to enable it. I appreciate your feedback, thanks again.

As you probably know, mine only has one Sim slot and when I go to settings and drill down into the mobile network options, under 'Advanced' Enhanced LTE Services is already enabled.

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Xiaomi Mi Max 3's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.

Not so good, my first day out of the house with the phone and it dropped T-Mobile service twice while I was on a call.

If you like you can use Network Signal Guru and measure and take screenshots and post here to give some actual data if its good or bad.
Which bands are used when and how long and when a call cuts out.
And when its very good to give a comparison when the phone performs very well and when not so good.
However Network Signal Guru requires root permissions
https://play.google.com/store/apps/details?id=com.qtrun.QuickTest
Some alternative apps are
CellMapper
https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper
Network Cell Info Lite
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
SignalCheck Pro
https://play.google.com/store/apps/details?id=com.blueline.signalcheck

I don't have root yet however I do have the so called global firmware. Maybe that's the source if it is indeed a fake ROM.

So I just noticed something. When I make/receive a call I immediately drop LTE. Once the call ends it's restored. I have to assume the phone is not capable of voice over LTE or I need to find a toggle.

that is normal....all phones switch to 3g when on call (even U.S carrier phones)...unless doing VOLTE...then mobile data unvailable during call ...Samsung S8 does it on Verizon (so does Iphone 7)

I know as I stated in the original post the phone must not be compatible with Volte as there is no toggle. Additionally it's dropping to edge instead of 3G whenever I receive a call

---sorry wrong info-not verified

I am on AT&T and have been hoping you posted an update to your initial findings.
So text,calls are working as intended now ?
Appreciate the info so far.

mac231us said:
anyone having issues with simply making calls, sending sms and accessing the internet? anything in the *#*#64663*#* phone service mode - phone seems to want to always sit in TD-SCDMA/LTE mode instead of LTE/UMTS mode. Always reverts to it. Not sure if that is the issue. HORRIBLE experience with this device so far. Right off the bat when I got it, it was doing sms sending (forever in sending mode until failed or sms would come in after like 15-20 mins and only after a reboot) Incoming sms no issues. Message center is ok. Then data was an issue. Switching SIM seemed to fix one first call then the 2nd call would just sit in dialing mode forever and ultimately hang up. Garbage device (so far) unless it is some simple fix. This is on ATT.
EDIT finally managed to fix the issues
fastboot mode
erase cacne this went through
erase data did not work
then did factory reset through the recovery mode
booted it up
inserted sim...everything works now (for the first time)
bootloader was unlocked by the vendor/someone upstream prior to shipping
very fast...even on 4g
lte comes on selectively so far only seen band 5 (no band 4)
EDIT2
So while mui is pretty slick and the phone is easy to use, fast, great on battery it still suffers from a Xiaomi-related bug (will call it that) in call-forwarding. You cannot set call forwarding (of if previously set - when the sim is in another device, of course), the call forwarding cannot be disabled (SIM error) This has been an issue for years - yes like since 2014-15...since the user base is mostly overseas, you can see complaints but no real resolution (useless feedback from thread owners etc who talk about contacting the operator, removing sim card etc) This does not exist on Huawei, Oppo etc phones (having used them) Even some miui ports suffer from this on other devices (so it seems very likely an MIUI issue) I have an old Samsung Mega that has the same issue on a ported MIUI for it. The Mi Mix I had a few months back had the same issue. No one ever fixes this.

I dont understand the steps that you did to fix the problems.
Could you please make it more clear and tell us exactly the commands you did in fastboot mode / not in fastboot mode and give us clear instructions? like I dont understand "erase cacne this went through
erase data did not work"
Thanks bro and Im happy that the problem is solved for you.

No...I think there was no issue. I was doing something wrong in selecting bands that don't exist here through the service menu-so am all confused apologize for posting off and on and then posting a 'solution' for something that probably never existed. I see my post was quoted-hopefully it does not mislead and start a plethora of unnecessary questions-you may want to edit what you quoted from my initial post-just a suggestion thanks

Everything is fine except Calls. I've been told my phone rings once then goes to voicemail and occasionally I will connect to another party but we can't hear each other. Phone calls work less than 2 out of 5 times. Text is flawless, data works great with the exception of slow handover when switching from wifi to LTE.

And you are on T-mobile ? My friend ordered one and he's on the same service as you so I can tell him what he might expect. I don't know if Mac321 is having the same experience or not on ATT.
I want to buy the phone but I'm trying to gather as much info as I can before hand so I don't have to return/sell the phone.
Thanks for the reply

Yeah if it's not fixed I'll have have my calls forwarded to Google voice number and do VoIP calls.

Hey I fixed it. Found a post on a thread that will enable VoLTE on Xiaomi Phones. Apparently they disabled VoLTE starting with MiUi 9 due to lack of certifications in certain countries, the US being one of them. To activate it dial *#*#86583#*#*

Band 4?

Are you getting Band 4 LTE on Tmobile? Also, how about 3G/HSPA? I believe it supports Band 2 for those, right?

Band 4 LTE is rock solid everywhere however I cannot connect to 3G anywhere. That's why I had issues with calls before I activated VoLTE. I'm not sure if it's the phones band capability or something else but even forcing 3G nets me 2G edge. Thankfully I don't need it.
