[Q] My phone has no phone number...?

I bought my Vibrant off-plan, then swapped in my SIM from my G1.
This means Android doesn't know my phone number. Does anyone know how to set this? Apps like Nimbuzz complain about the missing number.
What? Are you not able to make calls? I took my SIM card from my G1 to a Vibrant and worked fine. What happens when you try and put your SIM card in your G1? Does the # appear again?

Yup, that's it. I'll try the OTA activation message thing. Thanks!
I had this problem on my MYT3G. TMO support was not able to assist.
I finally found a solution here on XDA. (cant find the link right off hand)
I removed my SIM,
powered up the phone
shutdown the phone
installed SIM and voila.... My number now shows up on the phone.
I had this a couple of years ago with my G1. I called T-mo, let them know... 5 minutes and a reboot and it was showing up, no problem. Just call T-Mo...
Thanks again smerff, that worked and the T2 support lady fixed my friend's missing number on the same support call. Can't argue with that!
Mine had always been like this, in my old G1 and now. Figured it was my sim card, I never looked into it though. Maybe I'll call Tmo and see what they day.

This was like this for me with my old SIM card (had it since the days of the first PocketPC Phone Edition from like 2002). Replaced the SIM for other reasons with a brand new one and now my phone number shows up. Don't know if that was the reason or not.
The tmobile rep told me that they were duplicating old sim data to new sim cards for issues just like that. Don't know how that would affect anything or why. Just an idea.

Wrong number

Did have a search but could not see this anywhere so;
Not so much dual booting as dual personality
I recently gave my number to a friend and looked in about phone/status to get it as I can never remember. Mt friend could not call me and I have just realised that the telephone number the phone thinks it is, is not the correct one. Can this be fixed? How did it happen as I am sure it was the correct one originally.
try to turn off your phone, remove your sim card, re-insert your sim card then reboot.
I have this too, also can't fix it. But I think it is carrier related.

Yes did try this but still the same. Left the sim out for a good ten minutes as well.
Plenty of threads on the subject. Stick SIM in an old dumb phone and change the number there, it'll then show the correct number when put back in your smartphone.

[Q] SIM card not working

First of all, I'm in the US. I bought the Samsung Galaxy S II GT-I9100 (I'm in the right forum, yes?) off of ebay.
From what I remember, when I received it, it had some weird ROM that I had never heard of and can't remember the name of, along with clockworkmod recovery already installed.
I put cyanogenmod 9.1.0 on it via: [cyanogenmod's site, model galaxys2 cm9.1.0] (I can't post links yet, so I had to remove all of them).
I was using it mainly for development for a while, so I never tried to activate it on a network using a sim card, but recently I tried to do that with StraightTalk (using an AT&T sim). Nothing happened. I rebooted my phone multiple times, took the battery out, reseated the sim card multiple times, etc. Nothing is any different than before I put the sim card in (except the messages about "No sim card installed" have gone away). And in the settings, it shows that it can read the phone number from the sim. I actually talked to their support for a while and they couldn't figure out what was wrong. I tried the sim in 2 other phones and it works fine on those.
I thought maybe the problem was cyanogenmod 9, so I tried installing cyanogenmod 10 nightlies made specifically for this model from: [cyanogen's site, model i9100 cm 10 nightlies] . Same thing with that. No network connection, emergency call only, etc. I've gone through the settings, trying to change things throughout. I've tried to force-connect to AT&T's network via the Mobile network settings -> Network operators menu, but it just says it can't connect to that network. When I tried to connect to TMobile's network, it said this sim card did not allow a connection to that network.
I wanted to double check to make sure the sim was actually unlocked, but none of the magic codes ( [cduu wordpress galaxy s2 secret codes] ) work except to display the IMEI. I've checked a couple online databases to make sure my IMEI is not blacklisted, and both said it was not blacklisted.
Getting pretty much nowhere, I wanted to return it to stock, but when I read up on it, I could not figure out what to do in order to do that. I'm not very experienced with the GS II; my personal phone is the galaxy nexus. After reading up on it, there's about 100 different versions of "stock" for this phone, depending upon what country/language. I don't know where this phone is from, but the only booklet it came with was in French.
I did find the sammobile released firmware versions for jelly bean and ice cream sandwich (I9100XXLSJ_I9100OXXLS1_OXX.zip and I9100XXLPH.zip) from [sammobile's site] . I don't even know if these are technically stock though. The only one I tried to flash was the ice cream sandwich one; the jelly bean one is still downloading. When I tried to flash the ice cream sandwich one using Odin3 v1.85, it just failed. Didn't harm any of the software that was on there, so I'm guessing it found that it wasn't the right version for my hardware?
So after all this work, I'm coming up empty.
Is there anything else I can do to try to troubleshoot why I have no cell network connection at all?
Should I try to flash back to stock and if so, can anyone tell me what english-language version of firmware/software I have to flash/install to my phone to get it back to stock?
Can I provide any more information to help?
Thanks for the time.
Since you have verified that the sim card is working properly.
Then the issue is with the phone,did you check with the provider if the imei of the phone is valid or not. It maybe a blocked device because it was reported lost or stolen previously.

I only checked in a couple online databases and they both said it was not blacklisted. I found the IMEI issuer at imei-number .com though, and it says it was issued by BABT (British Approvals Board of Telecommunications). Is that who I would contact? I don't know how I would contact them and get a response. Other than that I don't know what carrier the phone was used under before.
If it is not blacklisted
It maybe a hardware issue in that one pins for the sim card is not making contact properly. You may need to take the phone apart to see if there is an issue with sim connection.
Would it be able to read its phone number from the sim if a pin wasn't making connection?
Under About Phone -> Status, Network is Unknown, Signal strength is -111 dBm 1 asu, Mobile network type is HSDPA:9, and the phone number is listed correctly.
Oh, one thing I didn't mention is that the device ID from "adb devices" shows up as 0123456789ABCDEF.
And I just noticed in the About Phone -> Status menu, the Serial number is "unknown." Is there something in my ROM or something that is blocking or has erased the serial number or device ID?
Any ideas?
I'm probably going to have to buy a new phone for development today, so if anyone had something to try before then, it'd be really appreciated.

Got Scammed with htc raider but can i fix it

Hi
i bought a htc raider from kijiji locked with rogers. the person who gave me the phone told me that it is locked with rogers so at the spot i just checked the functions like wifi etc and nothing much. after when i inserted the rogers sim card it did not recognize the sim card and still said no service. there were not signals coming and there was a cross on top of the bars. i tried it with other rogers sim card and the same problem. went to setting about phone network and every thing was disabled . i reset and hard reset but the same problem. i tried to get the imei number by pressing *#06# it just showed the letters"IMEI" but there were no numbers beneath it. i went to setting to check the imei number but nothing was mentioned there either. there was a imei number pasted on the rogers box and under the battery so i called up rogers to ask about the phone and they said it was refurbished phone and it is out of warranty so they cannot help me out.
is it a possibility that the guy tried to unlock the phone and could not do it correctly. is there any ways i can do some thing about the phone. every feature is working fine but the every thing related to calling features. its like now a ipod of android
please help me. if unlocking , unrooting is the option please tell me or paste a link to do that. if you require more information to resolve this issue please mention in the comments and i will let you guys know
thank you

Receiving/Making Phone Calls w/out SIM or WIFI!!!

OK this is my first post and it's a weird one. I've always known phones to be useless without a SIM card except for emergency calls. Well today I purchased an S4 on Craigslist. As I was bringing it home, it started to ring. I didn't answer it and shortly after I received a text. There was no SIM in it so I thought it was weird but left it alone.
When I got home, I did a factory reset, put in my old SIM card and activated it to my number. Everything went well - received texts normally, emails worked great, called my husband's phone and worked great until I looked at his phone and saw that the number that popped up wasn't mine, it was the old number. Tried calling my phone with his and went straight to vmail.
Seems like everything activated correctly except for the phone function. Called Verizon and the rep thought it was odd as well since texts went through, but could not figure it out. The rep said the phone is probably tampered with, but I've never heard of anything that could make phone calls without a SIM or wifi.*I reactivated my old phone and left the S4 with no SIM and it's still able to make/receive phone calls!! Weird!
All IMEI numbers match, physical and in About Phone even on box. Phone is not rooted according to Root checker.
Please someone tell me what this is so I can just can undo it and activate my number to the new phone.Thanks
Maybe Verizon or an emergency service was trying to call you... They don't need a sim for that.
The old phone issue is normal every time they port a number or switch a number they [email protected]#$ it up I've had it happen a couple times it on their end not yours

The Sim is only for LTE service, you use built in CDMA radios for calling.
I honestly don't know about the number issue, take it to a corporate Verizon store (the private stores only care about sales not customer service) to have them properly activate it.

Sounds like the phone is set to nv-only mode. The vzw s4 is fully operational in this mode but it won't pull your phone info from the sim card.
This is the mode we put the phone in when flashing to carriers like page plus, selectel, etc.
If you want, you can PM me the meid of the device and/or the phone number the calls are being placed with. I'll check to see if it's an active page plus account.
