[Q] No data service on SII - AT&T Samsung Galaxy S II SGH-I777

Hello,
I have an HTC Aria on my AT&T plan. I cracked the screen and figured it was time for an upgrade anyway, so I bought a GSII from a friend. I powered off both phones, moved my SIM from the Aria to the GSII, and powered it on. I can text and call, in and out, but I have no data service. The strangest part is that when I first powered on the phone, I had data for a few minutes. Then it disappeared, never to come back again.
I can move the SIM back to my Aria and everything works normally again. I assume since I can call and text the IMEI is not blacklisted. I've checked APN settings and they appear OK. The phone came with stock 4.0.4 so I rooted and upgraded the Kernel. This is frustrating me to no end. If you have any ideas, please let me know.
Thanks,
Will

Simple.
Call AT&T and tell them you got a different phone and need your plan adjusted.

Likely you are still using a 3g plan so you can't use the apn labeled phone with a separate mms apn unless you have your data plan updated. In the meantime set a new apn like this (Don't use the Quotes... just enter the information and the remaining lines are left blank):
Name"ATT 3G SIM"
mcc="310"
mnc="410"
apn="wap.cingular"
user="[email protected]"
password="CINGULAR1"
server="cingulargprs.com"
mmsc="http://mmsc.cingular.com/"
mmsproxy="wireless.cingular.com"
type="default,mms"

[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?

maybe. he say in settings -> about phone -> status-> my phone number. i have my off plan too n i have some problems with some applications that say. idont. have a phone number

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.

[Q] Full 4g data working, but not voice

Ok, so i'm new to this whole android thing and came up on a TB. Sorry for the noobness of this...i did a search, but couldn't find anything relating to my problem. hoping someone could give some advice.
I tried to activate it the other day and it took some time to activate(i guess Verizon's network was down), but the 4g LTE was fully functioning. Phone was recognized on my account at verizon and everything checked out.
however, when i tried to make a phone call, i got the message 'welcome to verizon wireless. your phone number is not active or invalid'. one thing i did notice was the roaming triangle above the signal bars. btw, i did try contacting verizon and they didn't know what was going on..they kept blaming the downed network.
i couldn't get it to work so i had to switch back to my whackberry.
Anyone know what the problem is and how to activate it? any advice would be awesome!
thanks for the help in advance!

Internets keep cutting out

I had this problem running miui, cm7, and now I'm on unnammed. I've used all the modems and still nothing helps. I thought unnammed didn't have this problem? To fix it I haft to flip to airplane mode and back, then its fixed.
Sorry if this has been asked. I'm on taptalk on my phone and I don't know how to search with it

Could be APN settings. I don't know them off hand, but they are listed in post 2 of the miui thread.
If it happens on multiple ROMs it could also be a bad SIM card. Does it do it on pure stock? If so, try a new SIM card.

Are you talking about wifi or 3g?
Are you using any battery saving apps like Juice Defender?

This. I haven't seen this issue reported often, and in the past, it's turned out to be an app interfering with the connection. If not, it's likely an apn issue.

I've had the same thing happen to me on other AOSP roms too. On both the SGS2 and my captivate.
I just switched to iscrewed to see if the prob is still there. Its hard to reproduce the bug, but it happens when i go from either:
1. being connected to wifi for a long time and then leaving that area, mobile data doesnt turn back on
2. being in a bad service area for a long time, and then leaving it, mobile data doesnt turn back on.
The worst thing about it is i use google voice for texts, and thats usually how i can tell that it cut out, because i stop getting texts from people.
I love android and google, but honestly if problems like this dont get ironed out, then as long as the next iphone has a decent size screen im probably switching over.
FYI this has occurred when i had the bare minimum installed on my phone, and i never use any ridiculous battery saving apps.

I might have to switch back to cm7 just to name sure it's the Sim card that's causing it.

ill try this out tomorrow. just now when checking my email i had to turn on airplane mode and back off to get data to work.
also, i tried the apn settings on the first page of the miui thread and it didnt work. i tried those settings on miui, wiui, cm7, and unnammed but they all made it so that my internet didnt work at all.
so just to clarify, i shouldnt haft to change apn settings and my phone shouldnt be doing this on non stck roms, right? sim is likely the problem? this has gotten really old really quick and its embarrassing when im trying to show my friends something but my phone isnt working.
Your phone should work fine on any ROM you find here. Mine does. I never have to play with APNs, even on miui. I never have to play with airplane mode or power cycle. But, when my SIM was bad I would drop data connectivity all the time. Calls would fail (outbound only), and other glitchy reception issues. Sometimes airplane mode fixed it, sometimes power cycle, sometimes airplane mode on, power cycle, and all times it was temporary. Its worth a try, shouldn't cost anything to get a new SIM. If they give you trouble at the store just tell them you called 611 and they told you to go in for a new one. If that doesn't fix it go warranty route for a new phone.

Those APN settings have worked fine for me on both CM7 and every Sammy ROM I've used. I always have (unrelated) problems with MIUI, so I can't verify that one.
So i went today and got a new SIM. Its been about 9 hours, but no problems yet. Time will tell if it works, but im willing to bet that was the problem, and this is why.
When i went to get my sim, the guy there told me that when ATT started rolling out 4g phones (which includes 3.5g) many employees had trouble with their data switching on and off until they switched their sim cards.
Then i started thinking to myself - I've had the problem about as long as I had my SGS2, and only had the problem with AOSP roms on my captivate - then i made the connection.
When i used a stock, or stock based rom on my captivate, i had no problems. The second i used an international ROM, or an AOSP rom is when i would have the issues. What is the difference between the roms............. The ATT rom doesnt have hspa+ enabled, so using my old "3g" sim card i was fine. No 3.5g to connect to to cause problems. CM and international Roms would use that new 3.5g network and would then screw up.
That is my theory anyway, and if it turns out true it would have solved one of my biggest annoyances with android. (or at least my android experience)
fingers crossed
i too went in and got a new sim. my phone service actually quit working before going in. id get calls and i could hear them but they couldnt hear me. i replaced the sim and all is good. where miui would hang and data would freeze and id haft to redo the airplane mode trick, it would just hang for a sec or 2 and then start downloading again. ive only had it hang 2x now and i think its because it might be switching from hspa to 3g or even wifi.
so for the sim card thing worked. if it fails in the mean time, ill come back to this and give an update. thanks for suggesting it being the sim card cause i wouldnt have thought of that.
I'm another day strong without any problems. I don't know of its due to the new sim or because i switched to a Samsung based rom. I should switch back to test, but I'm loving the speed of icsrewed right now.
If i had to guess i would say it's due to the sim, and if so, there should be a sticky somewhere that says to make sure your not using an older 3g sim card. Would have saved me months of aggravation.
Will report back after a few more days. In a week or so I'll switch back to cm to see if it fixes it there as well.
That's one reason I generally buy my phones at the att store (authorized reseller, but dedicated to att phones). Usually they will price match, and they know things like that. My SIM went bad when I had my captivate. Later when I upgraded to a faux G phone the att rep knew I would need a new SIM, and replaced it then, even though it was only a month old. They also knew the "3G" data plan needed to be converted to a "4G" (still unlimited) plan on their system for me to get data.
You don't get that kind of assistance when you buy at Walmart, online, etc.

Amazon Mobile just sends you a new simcard anyways lol
Interesting, maybe next time if my data refuses to work I should bug at&t for a new Sim card. I had problems on different roms including stock rom where I had to turn off and on my data or else it will not work. But I think my modem might have played a role. Data seems fine now.

Yup just show up. They shouldn't charge. as long as your an att customer theyll take care of you. I've never heard of anyone paying for a new Sim. If you lose your Sim I've heard of them charging people, but i doubt they'll charge even then.

Urgent Help! Can't Answer Calls???

For some reason my rooted stock S2 (from Bell unlocked using on Rogers) can't answer calls. I can call out without any problems but if someone is calling me, it'll hang up on them as soon as I answer. They then get a busy signal.
Any ideas?

Can't find phone.apk.... I deleted the cache of dialer.apk and the problem still remains. I also completely turned off call blocking and everything.
When I answer a call, it immediately disconnects.
This is interesting to hear. My wife and i are both on rogers. She has a rooted and rommed captivate and i have a rooted and rommed nexus s. We are both having the same issues for that last couple days. Weird stuff. Never happened before.
I put my SIM card into my wife's S2 (also stock and rooted) and it works properly. Accepts incoming calls. So it must be something with my device specifically and not network related. Strange... I've removed any possible suspect apps to no avail so far. Perhaps a core app update is the culprit.
Ya I am confused lol. I have been on the same rom for a few weeks now. Just started happening to both of us all of a sudden. Not sure if it is a certain app that we both have installed and its screwing up our phones? Just not sure at all.

I've been having the same issue with incoming calls all weekend, in my case I was able to rule out hardware by swapping SIMs with another Rogers phone.
On the phone a few times with Rogers Tec Support and I was told this was an issue on their end, from what I'm told it's related to the Rogers One Number service which I did register for a couple of months back. Although I don't use the RON service anymore it's still active on my account.
I just had Tec Support remove it from my account and am just now getting my incoming calls again.

This may be it. I recently signed up for Rogers One Number but never use it. That's the difference me and the wife's S2. She's not registered for One Number. Hmmmm..... But it's weird that my SIM accepts incoming calls on her device though.

[Q] No Service/3g

is it possible to have a phone flashed badly or wrong? My Samsung Galaxy S4 was originally a U.S Cellular device, but was flashed to Verizon Prepaid. I basically have NO 3G. If and when the icon pops up, the minute I try to search or do anything it disappears.
My phone calls are fine, but my data is averaging 1X to nothing at all. Sometimes I cant even get a picture message out. I is driving me nuts, Especially when your paying for a service you cant use.
Was it possible that it was flashed wrong or bad? or is this something else. I have been trying to get it taken care o by Cricket King (ebay) but I think they think its on my end.
Any help or advice would be appreciated. Should I have it re flashed
Hmmm....I'm not a developer, but I do troubleshoot. Are you using Verizon SIM card? I believe once it's active and inserted you should have full functionality.
Sent from my SCH-I545 using xda app-developers app
I'm no Dev either, but did you set up the APN settings right? I would assume since it was flashed to a different network you would need to set it back up to work on the Verizon network. As for what those settings are I'm not sure. I've always been on Verizon and haven't had to mess with that stuff

Usually it ends up just being the APN's or the sim card. Since these phones are already unlocked it doesn't take much to get them going on another network

Well I don't know about the PRL much myself. I know my sprint s4 needed the prl updated from time to time but that's sprint.
And your sure your not using a sim? I'll be honest I'm not really sure about switching carriers and all that. Just from what I've read on here I've seen many people do it fairly easy.

You must be using a SIM card because both U.S Cellular and Verizon need a SIM card. But to update the PRL type in your phone *228 and it should come up with a message saying it has been updated. Even though 4GLTE devices automatically update. Also, I would go into Settings, Connections, More networks, Mobile networks, Access Point Names, and make sure there is a green dot next to Verizon.
