I'm guessing it is related to APN. Contact that provider or see if there are APN settings on their website you can manually input into your phone settings.

You need to find out what APN settings the provider uses. I suggest finding it on their website(if they have them), or contacting them.
You find APN in settings -> mobile/cell data (access point names)

but it does not solve problem

Have you checked your sim card? Sometimes this could be the problem because it could be damaged. If you are pretty sure it isn't damaged, try changing modems or maybe try changing network modes from 3g to 2g or something along those lines.
Go to about phone, status and see if it registers any signal at all in signal strength. If there is 0 asu or 0dBm, this could be just an issue with the carrier and not the phone, meaning that you might have to contact them so that they can correct the issue (in person is probably the easiest for the provider to do).

Not Registered on Network

Woke up this morning with everything working. Got out of bed and place my phone on my desk and turned on my computer. I then looked back at my phone to see i had not service. Confused, i restarted my phone to see if that worked and it didnt. I tried another sim and it didnt work either. i then put both of the sims in a iphone and it worked there. I restored the phone to stock and 2 other roms and it still isnt working. The weird part is when on stock i get signal bars even when their is no sim. When i try to dial out i get "Not Registered on Network"
Any help is great help
Wrong section, ask in the general or Q&A.

Have you checked your Settings? Still got IMEI? ([Settings] [About Phone] [Status]) Phone connected to correct Network Operator? Access Point Names has correct data in it? [Settings] [More Settings] [Mobile Neworks]
Thanks for the responses. I had a rom running on it for a little bit over a week and didnt make any changes since. I also do have an Imei and an apn

It doesnt even show my network operator, thats the weird part it only shows rogers and when i put a sim in for fido (Rogers>Fido) i got service but no h+ even with the correct apn i only got edge
My Network operator doesn't show as a normal either - I do a Search and get (after a wait) Telstra, Optus and Voda - choose Telstra and it pops up a 'Registered on Network' msg.

yeah when i search i only get rogers???? This is the single most awkward thing ive ever seen
EDITTZ Found the problem. The phone switched itself to only look for one band not all. +_+ dont know how it got their and how it pertained through all the wipes but got it working DDDDDDDD
i had the same very exact problem..and yes when its in auto mode it only detects gsm signal so the data is slow signal is E.
i usually use the wcdma only option so that the phone on searches for 3g h and h+ but now when i select that option it only gives me
not registered on network..and no data signal at all.. and also the weird thing is that there is a signal bar on it plus when i scan for
network it searches the other two carrier brand on our country not the sims own carrier. help anyone

Hey xTristinx, glad you got your phone working.
I have the same problem on my Galaxy S, my SIM wouldn't register a network on it but it worked on a different phone. My Galaxy S still gets a signal but always says "out of service". I think this might be a problem because my friend used his SIM card in my phone and it f***** up the bands. Could you give me any suggestions on how you fixed your problem?
Thank you.

S2 can call and text but cant connect on mobile data.

I rooted and flashed my GF's SGS2 with wanamlite 13.0 ROM and its perfect.. but now, she called me and asked why she cant connect on the internet using mobile data.
No signal indictors like 'E', 'G' or 'H' are showing even she enabled the mobile data and neither changing GSM to CDMA vice versa worked.
She has also tried restarting the phone, searching the network operator and choosing the right one but to no avail. Her sister also has the same network provider but she doesnt have any problems on the mobile data.
Is it possible that it is a Phone defect? I really doubt it since she can do text and call using her SGS2.. Im confused >.<
PS: I've already tried searching this kind of question so please, dont post 'letmegooglethatforyou' links. Thank you.
First thing you do is go to the carriers website & get APN settings, write them down & check the APN settings on the phone. If there are APN settings on the phone but they're different in any way to the ones you got from the carrier's website, change them. If there aren't any on the phone (in settings/mobile networks/access point names), these need to be entered, make sure APN type is set to default.

Thank you for your wonderful advice..
Im so stressed that I even forgot that there is an APN settings needed (I swear that it is automatic in my own S2).
Anyways, I'll call her once again and try to work things out.. I hope she can understand and follow how to check/change the APN.
Will update once done.
Thanks again!
No probs Post again once you've checked/put the correct APN settings in if it's still not working & we'll nut it out further.

[Q] Dual sim chinese S3 clone roaming problem

Hi
My phone is Star OneM92 dual sim Chinese S3 clone running 4.1
I'm experiencing a problem with my Virgin (UK) sim. The phone is automatically throwing it in to roaming mode. The "r" sign comes up at the signal bar.
I've checked with Virgin and they confirm no roaming charges apply as its a domestic sim. Of course when I told them the phone is copy they immediatly threw a fit and I got a lecture how I should never of you one in the first place.
Its dam annoying when I make a call. I have to confirm I want to use a roaming sim.
I've tried different positions and other sim cards from O2 and Vodafone and they work fine.
Can anyone shed any light on to this and advise how I can get around this.
By the way, I know I shouldn't of got a clone and yes I'm a noob and all that. Apologies for my inexperience in advance
have u try using a app from playstore called network
there u can set the phone to only 2g 3g or roaming
or go into settings an sim manager then network an disable roaming

Data Roaming not working on Android

Hi guys, I'm having this bizarre problem that I hope you could help me with.
I currently have an iPhone 5S, SGS4 and HTC One and share a single sim card between all three phones.
In my home country my SIM card is able to access data on all 3 phones with no problem.
However, when I go abroad and use data roaming, only the iPhone is able connect, both android phones are unable to connect at all.
I checked the APN settings and all seem to be correct.
Any ideas?
Thanks!

Have you enabled data roaming in settings..!??
If you are using a custom rom you can find it in settings - - > more - - >mobile networks... Tick the data roaming option... I've never tried data roaming as I don't travel much... But that might help you..! [emoji106]

Yup it's ticked for sure. On the HTC it says that APN settings are incorrect, on the Samsung the phone just refuses to connect. If I move the SIM to the iPhone, data roaming works flawlessly!
When I'm back home, I have zero problems with either phone, which leads me think this is either an Android problem, or a SIM card problem.

Then I guess it has something to do with APN's... Maybe it requires different APN's for roaming... And somehow iPhone has them by default and android doesn't.... Contact your service provider and get the apns..!! That's my best bet.... Good luck

[Q] help to enable APN settings

I recently moved to US and brougth my mexican S3 with me, there I have service without a problem using 4G, before comming to US I took it to a shop to get it unlocked to be able to use a US SIM.
When I got here I purchased a T-Mobile SIM card and service went up. But network doesn't get 4G service, it keeps switching between 3G and H networks, most of the time H I took it to a T-Mobile shop and there they told me that it is not getting 4G because they can't set IPV4 settings as those fields appear as disabled in the APN settings screen. And they said it's a hardware thing.*
I just wanto to be sure that thus is a hardware issue, or if is there a way that I can enable IPV4 setting by a software or configuration change so I can set those values before having to change device.
I also brougthwith me a galaxy note 2, and it's the same problem but a little worst, as it only gets E network service, do you know a way to get them to work properly in US?

Have you tried using an app called "Apn Global" from the play store?
