Phone identity

I have ported my number from 3 to T-mobile and the porting went ahead yesterday, and everything is ok in terms of calling, receiving calls.
However when I check Settings, About Phone, Phone identity, to old number (T-mobil) shows up.
I have switched it off and back on, I've removed battery & sim, but still old number showing.
Thoughts?

Same for me...not overly bothered tho

it's because the new SIMs come with their own number programmed into the SIM.
You could change this on Windows Mobile by using the SIM manager and in the menu you had an option to change the 'My Numbers' stored on the SIM.
Don't know of any way to do this on Android.
Anyway, just save your number in the contacts list in 'Me'.
It really is nothing to worry about, but you can go ahead and dump the SIM into another phone to change the number if you really want to....

It's annoying when you know it's wrong isn't it?
Mine read 'Unknown' so I took my SIM out, jammed it into my spare WM phone and programmed it in SIM Manger as mentioned above.
Android still reports it as 'Unknown', I can't win

Yes I definitely want to change it... uhhh So no app for Android does this yet?

Depends. Personally, this wouldn't bother me in the slightest. My last windows mobile phone said unknown for the whole time i had it. Made no difference to me whatsoever. but that's just me. I have other stuff to get annoyed about
I guess it just can't read it from the SIM for some reason if it's still showing as unknown. And AFAIK there is no app for it. Although maybe someone else here knows otherwise?

[Q] MMS doesn't work. :(

I purchased a Galaxy s3 on ebay, SGH-i747 AT&T. ICS 4.0.4 Stock ROM
I used the sim from my old phone and chopped it down, everything worked except MMS. Here is what I've done to try to resolve the issue in order. I searched around the forums and many of the solutions that have been posted were for other types of phones or carriers, the rest didn't work for me.
1. I disabled some of the apps in the stock rom (I haven't flashed a new ROM)
2. I went to an AT&T store and got a micro sim to see if this would resolve it, nope...
3. Installed "SIM Info" from the play store and it shows "SIM Operator Name: Unknown" and "Network Operator Name: Unknown". I have another active AT&T phone (S2 with Paranoid) and SIM Info on it shows "AT&T" where the S3 shows "Unknown". Wondering if this might be the issue, but how can I fix that?
4. I checked the APN and all seems in order, I even copied the APN settings from my other phone. When I go into the network operators and search, no search option comes up, just a grayed out "default settings" thing. I'm not sure if this is normal for a stock ROM.
5. I rooted the phone and put TWRP and SuperSU on it.
6. Installed gApps (first I put on the JB edition by mistake lol, but I fixed that).
Also, I'm not sure if this is a stock rom thing, but the signal bar is always gray, not sure if it is supposed to go blue or not. I do get indicators that 4G is connecting when trying to send MMS. So what can I do? I don't want to install a new ROM on this phone because it is for my wife, but out of the box with the stock ROM MMS isn't working. Is this something that I need to take into the AT&T store and just tell them it is broken and hope they have a solution?

Does not send. Eventually fails, and I can't see any error message.
Does not receive, the download button is there, but it never downloads.
No one receives any MMS from this phone, nor any kind of indicator that a message has been sent from it.
Stock MMS and third party app (handscent) both act the same.

Bump
Any ideas? Would logs help? Where can I find them?

You chopped down the sim? As in you cut a big sim down to size?
That might be your problem...

As mentioned, I got a new sim from AT&T after I cut the old SIM down to the micro size and the problem is still there. However, I cannot rule out the SIM being the issue, since SIM Info shows the newtwork operator info as "Unknown". So I guess I should go to the carrier again and get another SIM? Internet, SMS and calls work great on it, just MMS fails. Very puzzling...

there's your problem. It doesn't communicate with google servers (grey vs blue). a little google search (or xda search) will give you the ''how to fix''. Just last week, I made a post about it here but can't remember the solutions specificly.

Ok cool, I thought it should be blue... Is this the thread you are talking about? http://forum.xda-developers.com/showthread.php?t=2102674
If so, your steps are as follows...
BWolf56 said:
1- Just restart the phone without the SIM card, and connect to some WiFi network, so you can login to your Google Account. It will log you into the account, and then you can put the SIM card back.
2- Add YouTube app and login with gmail account
Go into Gmail App and add account if needed.
Sign into Gmail account wither username and password
Go through login process
3- Hard reset your phone. You will lose all information that is currently on your phone when you do this.
Select Settings -> Security -> Factory Data Reset
Once the phone reboots, input your google account information when the phone asks for it.

I'm not sure if this will help, but I will give it a try. I am able to open all of the google apps including the play store and gmail and they are synced up correctly. The calendar seems to be having issues though, so it might also be related. Will this correct the SIM Info message of unknown network?

I tried Step 1 and 2, both passed fine, signal still gray, and still no MMS.
I am reluctant to do a hard reset, only because it is my wife's phone, and she gets annoyed when having to get her wall papers n stuff again. lol I might tell her to just deal with it at this point though. However, pending step 3, if it still doesn't work, and the SIM card still shows unknown network, what options are left? Go to the carrier?

Possible that the phone is bad, maybe that's why the seller sold it, knowing it was a bunk phone. Worst case you can send it in for warranty. Curious, are either of the water marks on the phone pink? My wife dropped a phone in the bath a while back and started having issues with the SIM randomly not being recognized and then not having data (it wasn't her s3,I think it was a vivid.)

Carrier will either factory reset your phone or give you another SIM. One last thing I can think of is that your MMS are blocked (not in your contract). So that could be something to check with your carrier (or on contract).

I doubt it's the case here as everything else but MMS works. A damaged SIM or connector won't only block those and let the rest work :silly:

Just speaking from experience, I've seen it happen first hand... voice and sms will gimp over a connection sans data, mms on the other hand won't. It was confirmed that the issue my wife had with her phone was a shorted out contact point in the SIM tray. Additionally, the op said he cut down the original SIM, it's possible he didn't do something right and physically damaged something.
I work in an profession that requires me to trouble shoot issues constantly, I learned long ago never to assume that something, regardless of how silly or implausible it may seem, May not be the culprit... we know a few facts...
the phone was purchased second hand.
The SIM card was cut and the phone is not correctly reporting the status of the SIM.
SIM has been replaced, not correcting the issue.
Apn settings have been verified.
No factory reset has been performed.
Now, SIM cards and trays can be very finicky, I have seen a couple phones with bad SIM ports... the issue the op is having may not be related to water damage, but I have seen it happen and there is no reason to discount it until verified.

Are you sure it isn't an APN issue? You might want to go into Settings -> Mobile Networks -> and Network Operators and run a search. Then you can check the APN to make sure it is set correctly for MMS.

True, if it's Straight Talk, you'll need to manually add the MMS APN. I have to do this with pretty much any phone I use, though some ROMs will include ST APN settings.

Thank you all for your input. I'm going to do a factory reset on the phone tonight (if she'll ever get off of the damn thing! lol) and I'll post an update after that. If the SIM still reports that the network is unknown, I'll get a replacement SIM. If it still doesn't work, I'll go on the hunt for a SIM port replacement, but first things first. thanks again, I'll be updating shortly.
Oh, and it hasn't gotten wet, at least the indicators don't show that it has.

Check APN's before factory reset.

I had a similar issue, I had to call AT&T and have them give me the correct settings to put in under the "message setting" option under the messaging app settings.

Funny, MMS suddenly started working, both outgoing and incoming, but SIM Info still shows network operator unknown. :S I'm afraid that this issue is going to come back... I'm still leaning toward going into an AT&T store and getting a third SIM...

[Q] HTC ONE X phone number unreadable after upgrade to 4.2.2

Hi everyone,
I seem to be facing a problem that I haven't found discussed here with my phone.
Following a successful upgrade to Slimbean 4.2.2 build 6 OFFICIAL, everything seems to be working correctly with my Tmobile UK SIM card and I can make or receive calls and texts, I can read the IMEI reference but for some reason my phone number is not displayed anymore in the "about phone" section in Settings or if I use an app like "SIM Card" to read the details of the SIM. I get instead the message "unknown number"
I am not sure if this is a problem or not, so I would like to know if anyone can think of any potential limitation due to this issue.
On top of this, I am about to move abroad and was going to request a code from Tmobile to unlock the phone as I assumed the phone was locked to their network, but when I tried a THREE SIM card, the card was actually accepted and I connected to that network but again the phone number is not displayed in the settings section...
Has anybody seen or heard a similar issue?
I installed a fresh Slimbean ROM from scratch as I was previously running a completely different ROM and I assume it was successful as everything seems to be working.
The only issues I could find in the forum were related to not being able to retrieve the IMEI number after the upgrade, but nothing about the phone number itself.
I would be very grateful if anyone could offer any help or suggestion.
Thank you in advance.
David.

I have noticed the same thing on the official CM 10.1 builds (with both Three UK and giffgaff SIMs), I suspect it is an issue but it's not a real bother to me all it means that any app that auto detects your phone number (eg hangouts) will just ask for it during initial setup instead.
Again the same for the IMEI sometimes this doesn't show up but it does most of the time.

Thanks Hydo1,
I have found a couple of things yesterday.
First, I have been able to add the number manually through the settings menu in the dial pad and it now shows in the "about" section.
Second, I have found out that although my voicemail is setup and active when I call the Tmobile services, it doesn't actually work anymore and I can only guess it is due to this issue as it was working before...
I'll try again once I have switched to a new network abroad...

Should I upgrade my Sim Card?

I have been reading some really scary things regarding Sim Cards and viruses or malware or whatever and am wondering if I should change my sim card. A part of me thinks that the idea of a Sim card being infected is silly, but at the same time, I really would not know, lol.
If I were to upgrade my sim card...
Would it put my unlimited data at risk? (Verizon)
How would I go about changing my Sim? Could I use the sim that came with my note 4?
Also, should anyone even worry about their sim cards? o .0

SIM cards are free at corporate stores and you will not lose your unlimited.
Just take your phone in and ask for a new SIM. If they ask why tell them you've been getting errors or something. It takes like 5 minutes if there's no wait.
I don't think you can do a SIM swap online but you probably can by calling customer service from a different phone
Edit: If you call CS for a SIM swap make sure you have your other SIM on hand for the ICCID

Ah.. I see!
I actually tried to do a sim swap at home because google made it seem simple; however, it never worked to my knowledge. At first, I popped in the sim and it said that it was setting up, but never finished. While my phone was trying to activate with the new sim card, I went to the verizon wireless website and tried to activate my phone there, but could not find my phone listed in the section with previously activated phones. I did not try the option to activate a phone that wasn't registered already and just backed out. I did not - to my knowledge - see any screen indicating plan changes so I'm assuming that I did not do anything that could compromise my plan(?). When I dialed the number for activating sim cards, it went to the visual *611 screen and claimed that it did not recognize my number and asked me to log in to my verizon account. After doing so, nothing seemed to happen and it just sent me back to my home screen.
In hindsight, I probably should have stopped after it asked me to log in to my verizon account, but I suppose now all I can do is wait and ask questions to ease my anxiety x_x

You have to call that number from a different phone. Your phone doesn't hold your phone number so just popping a new SIM won't do anything.
You could try to do the "activate device" thing online but I don't know if there's an option to use a different SIM.

SGH-M919 No Data

Howdy,
About 3 weeks ago, I bought two refurbished SGH-M919 phones off eBay to replace mine and my wife's broken/old phones. Her phone was worse off, so the first one I set up was to be hers. Rooted, installed TWRP, and flashed Mokee with no issues. Put her SIM in, put her data back on, she's good to go.
I go to set the next one up for myself, do everything the exact same way, and came to realize after I put my SIM in that the phone is not connecting to LTE. Call/SMS/Wifi all work fine. I didn't notice whether or not it was doing this before rooting, recovery, and ROM.
It's giving me a "Sign-in to network" notification. I tap it, it takes me to a T-Mobile ConnectMe screen. It gives me a "Get Started" button, which I tap, and it says "We're sorry, you have switched your SIM card between different devices, so you will need to manage your account through My T-Mobile or the MyAccount app. Once you have replaced the original SIM card, you may resume managing your account through on-device account maintenance." I can only tap close. My wife's phone didn't give me this "error". I made sure the APN settings were identical between the phones, they were.
I called T-Mobile, they gave me a bit of runaround, said everything looked fine from their end, and "rebooted the connection" which didn't improve anything. They also had me verify my APN settings with them. They had me enter some different values, but it didn't change anything. They also advised me against purchasing phones from less than reputable sources. Great, thanks, that was helpful.
I switched the SIM cards between the two phones and this one is still not connecting to LTE, the other phone is. This led me to think maybe it was a hardware issue, and looked into the modem as a possibility. I found that T-Mobile updated the baseband last month on the stock 4.4.4 ROM, so I flashed that baseband and no change. Both phones were on NH7 when I received them.
I happened to notice on my T-Mobile account page that the device status is listed as "locked/unknown." So, I called T-Mobile twice today for an unlock code. The first guy was less than helpful but the second person did enter an unlock request for me, theoretically, I am currently waiting for that email to show up sometime in the next 24 hrs. But, the phone so far has not given me an unlock prompt so I'm not quite sure what I'm going to do with that unlock code once I get it. I'm also not 100% clear on whether the code is for a SIM unlock (which I shouldn't need) or what exactly. It is just the next in a series of ideas which I'm rapidly running out of. A check of the IMEI number revealed it was clean on all US carriers, with the exception of T-Mobile and Sprint which both come up as "unknown." Don't know if that means anything or not.
I'm getting ready to jam this eBay store up, but I'd really rather the phone just start working. I've been dinking with this for weeks and my frustration is mounting, especially since I can't seem to find anyone else who has had/posted about this problem before. I'm not a cell phone hobbyist or anything, and I'm just going off what I can find on Google and places like this. Any ideas/help would be appreciated.
Thanks,
Tony

I am not familiar with the issue, just some extra troubleshooting ideas...
Have you checked under the battery and confirmed the model number is SGH-M919 and the IMEI matches matches what is on the phone?
Have you checked your APN settings?
Have you tried flashing a complete full stock firmware -

I didn't flash a full stock firmware. I had issues flashing the non-hlos.bin to the phone, which as I understand it is the more important of the two files for my issue since it does the LTE. However, Wifi works perfect with transfer rates equal to the other phone. So, I don't know.
I'm downloading OK3 now. I read about a guy updating his modem by backing up his custom ROM, flashing a stock rom, and restoring his custom ROM. Will TWRP back up my current NH7 non-hlos.bin? If so, can I manually remove it from the recovery image without borking anything?

For your situation, just flash the full firmware. Don't remove anything from the tar. OK3 is the newest modem. Get your phone working and go from there.

Yeah, I think I'll do that when I get home, unless someone has a better idea. :fingers-crossed:

Try to flash the latest stock... Before flashing reset your device (take data/photo etc backup).... Hope that should resolve the issue....
Also what is it showing in settings > network? Is it LTE or 2G or 3G???
Sent from my SGH-M919 using Tapatalk

Thanks, that's the one I'm downloading and I'll try flashing it when I get home. It looks like it will replace TWRP and everything, bringing the phone completely back to stock?
In the mobile network settings > mobile network menu, it shows the preferred network as LTE.

Yes. It will be completely stock. If it works, you can then root and put TWRP on and go from there.

Alright, flashed the afore-linked OH3 ROM and the LTE is still broken. The phone shows up as connected to LTE, but nothing works. Play Store times out, both stock internet browsers time out. I still get the same T-Mobile nag that I got before and it still doesn't let me do anything.
Also got the unlock email from T-Mobile:
[FONT=&quot]Thank you for taking the time to contact T-Mobile. We have received your SIM Unlock Request. Unfortunately, we are unable to process your request at this time because we are only able to provide unlock codes for T-Mobile USA handsets.

Is there anything left to troubleshoot, or do I return it as defective?

If data works for your sim card in your wife's phone and not for your sim card in your phone, it would have to be a phone issue. You can double check if data works with your wife's sim card in your phone.
If your APN settings match your wife's phone with her data working, the last thing I can think of to try is go to Settings, under Connections go to More networks > Mobile networks and check Data roaming just in case your phone is roaming for whatever reason.
If your phone was locked on a different carrier, I don't think you would have cell service. If your IMEI was blacklisted or borked, I don't think you would have cell service.
I'd return the phone.

If your APN settings match your wife's phone with her data working, the last thing I can think of to try is go to Settings, under Connections go to More networks > Mobile networks and check Data roaming just in case your phone is roaming for whatever reason.
If your phone was locked on a different carrier, I don't think you would have cell service. If your IMEI was blacklisted or borked, I don't think you would have cell service.
I'd return the phone.

I will check on those two things when I get home, but my thought process was similar to yours. Both my wife's new phone and the LTE Wifi hotspot we use for our internet service have full signal on LTE everywhere in the house, so my best guess at this point is there's a hardware issue with the modem in the phone. I might look into replacing whatever board the modem is on. If it's relatively cheap, I'd rather just pay for the part instead of waiting 2-3 weeks for turnaround on the return/exchange, but I think that's probably what we're gonna end up doing.
Thanks for the help, fellas. I appreciate it.
