Hey guys, recently switched to AT&T from verizon 2 months ago. The guy at AT&T typed in the APNs and all is good besides poor reception at my house. Last night i turned off mobile data to see if my reception to send a text got better. Now I cant get mobile data to turn back on... It says add mobile service please contact customer service and gives the verizon customer service number. Any ideas on how i can get it back on? I've tried everything i can think of besides activating it on verizon again....
You might need to manually enter your APN since this is a Verizon device running on AT&T. Also if you are using an AT&T SIM you might need to input an IMEI for AT&T to get back on. These are the issues you run into trying to use CDMA/Unlock phone for one carrier (unlocked does not mean full functionality on all networks, if that was the case there would be only a single model of the V10) on a GSM carrier.

I did manually enter the APN... It senses not connected to VZW and then says to call VZW customer service... might have to activate on verizon again turn on data and switch sim?
The same exact thing happened to me a month ago
Go to: Settings>Backup & Reset>Network Settings Reset
it will turn your data back on by default but you might have to put your APN info back in
hope this helps
youre amazing!

my thunderbolt similar just went bad when switching between my thunderbolt and incredible. I did not hit *228 on my thunderbolt which makes your similar bad. the tech support Guy said once you activate another phone, the similar goes bad. is this true? if not l, what's the easiest method to do this?

My guess is he means Sim [card] and it's autocorrecting to similar
To OP: You're stuck, at least as it comes to your 'bolt, for the time being. You CAN activate another phone on your plan (like your inc) but the only phone on VZW that uses a sim right now is the 'bolt, so you will have to take it in and get a new SIM card, or have VZW send you one.
I don't have personal experience, as I haven't switched back from the 'bolt to a non-LTE phone yet.
So with the new SIM card, it is my understanding there is no need for activation anymore, correct? I had to have my first 'bolt replaced due to mic issue, and when I popped the SIM in the new phone, it just worked. I have never activated it. Any info if this is the case with all phones that will have a SIM. If it is I am so totally getting an Xperia play, if it has a SIM slot.

Right - the SIMs, as they stand, are interchangeable between 'bolts. No more activation or other things, but it won't work with just any phone - it has to be a Verizon network phone because the tech for 4G is different (it's not like when people could swap sims between ATT and TMo phones) - so, right now, since the Thunderbolt is the only 4G phone on Verizon, swapping SIMs will only work with other Thunderbolts
VZW explained it to me this way .... when going from a 4G LTE device to another 4G LTE device there is no activating anymore, you simply drop in your sim card. But, if you activate a non 4G LTE phone on your account that will deactivate your sim card and will require you to return to the store for a new sim card. This was in response to me asking them if I could switch between my Droid and Bolt.
For once VZW was very helpful in store. I normally don't go to the brick and mortars but being new to 4G I had questions I needed answerd.
The SIM doesn't get "destroyed" and can be re-used.. but... you have to call Customer Service for them to enter the SIM number...
here is what I did...
When I first got my TB, VZW was having network issues, and it took well over an hour for my "activate device" request to "clear the switch" and the TB to become active.
Having intermittent data issues over the next week, I decided to swap back to my INC, wait, and later return to the TB... I thought maybe due to the network issues, the TB didn't get all its programming info "over the air" or something.
When trying to return to the TB via the Activate Device link on the My Account web site, after entering the MEID/IMEI... I got prompted about needing a SIM... so I enter the SIM number and got...
"The SIM associated with the SIM ID you entered cannot be activated at this time. Please contact Customer Service at 800-922-0204 for assistance."
CS rep couldn't help... she had me on hold while she got Tech Support...
They had to manually add the SIM number back on the account.
Moral of the story... if you activate an LTE device and remove it from your account to use a 3G device.. you'll have to call back in and manually switch devices if you want to go back to using the 4G device.

The real reason you can't put your SIM in an ATT or Tmo phone would be the tech. ATT and Tmo use the GSM/UMTS/HSPA (3GPP) family for "2G"/"3G"/"3.5G" where as Verizon uses CDMAone/CDMA2000/EVDO (3GPP2). SIM cards are only on Verizon now that they're using LTE which is the next step in the 3GPP family but not quite 4G. Any phone made for AT&T or Tmobile is a "GSM" phone using the 3GPP family radios which are incompatible with Verizon's 3GPP2 network (towers). On top of that, they all use different frequencies. That's why unlocked iPhones can only use "2G" on Tmobile.

Were they able to re-add your sim to the account? I had a Thunderbolt which I traded for another phone, and switched to a couple of 3G phones in the interim. The Verizon store person told me my sim would be good for 90 days if I got another Thunderbolt. So I did, popped in the sim, and called support to switch over from my Fascinate to the new Thunderbolt. They got tech support on the line, and I was told that switching to a 3G device from a 4G device causes the 4G sim to be "retired" and that I needed to have them send me one, or go pick up one at the store. So the story was different from what happened to KidJoe and I wonder what your experience was.
A couple possible reasons why my situation was different: It was not the same Thunderbolt the sim was originally in. Also it's possible in playing around with the new Thunderbolt, I may have done a *228 just to see what would happen. Someone else suggested that would tank the sim.
I plan to go the store tomorrow and see if they can resuscitate my old sim, or if they give me a new one.
I had activated my thunderbolt when I got it with no problems. I decided to switch back to my incredible for a day and the sim was deactivated. Vzw gave me the run around between going to the store and calling customer service for a few days then they finally said they would have to send me a new sim because as soon as I switched to the inc my sim was "retired".

Yes. They were.
I did my switches only a few hours apart... (i.e. switched to INC, waited an hour, switched back to TB). And used the same phone and SIM. Not sure if that had anything to do with it.
There obviously is an inconsistency in VZW's system somewhere... the message you get when using "Activate Phone" on the my account web page to switch away from the TB says the SIM will be deactivated after 90days. But its being deactivated IMMEDIATELY. Either that message needs to be changed, or VZW's system isn't set up correctly.

Yea that's what they told me, I ended up having to get a new sim from the store
I recently rooted my phone with Casual's method. Everything went smooth on the flash.
Except I am unable to activate the phone through the verizon *228 method.
when I dial *228 it just says physically on the phone "A Verizon Sim card has activated your service and updated your phones roaming capability"
but then I got to call someone and it says I have no service.
I also transferred my service to my old Droid X while I did the rooting just in case that has anything to do with it.
Someone please help, at this point im about to return it to stock.

*228 is for 3G devices that have no sim. Thats what Ive been told and what ive experienced. Now you said no service, are you getting any bars or is it no bars at all. Have you tried going to mobile setting and toggling lte/3g mode. Also have your tried the hidden setting either by dialer and changing lte/gms/3g modes and then going back. Sometimes it may get stuck in a radio mode that doesnt get signal like in gms mode. I had been in the same situation and fixed it by doing the above.
New Sim card probably. That's your best bet

*228 is only for CDMA devices only, not CDMA/LTE. Your problem is that you activated a non-SIM device on your account after having a SIM device active. Doing so de-activated your SIM card, so you're going to have to go to a VZW store, or call VZW to get a new SIM to have service on your phone again.
I'm on AT&T,but just bought a rooted S4 off someone with a Verizon ROM on it. Would I just need to flash a AT&T ROM for the S4 to be able to get the SIM card to work with AT&T?
Any help appreciated.
Same here. My friend gave me his S4 today and it is Verizon and running on the stock ROM. However, I am on AT&T. From what I hear this phone comes factory unlocked so you just plug in the SIM and it should be okay. Is there anything else that I need to know if I want to use this phone as my main?

After a brief visit with AT&T today, they installed a SIM card from their carrier into my phone, but it would not get speeds grater than EDGE at the time. 3G may have been possible, but it didn't see it right away. Also, they had to update the APN settings in the Settings -> More settings -> Mobile networks -> Access Point Names. Lastly, after searching the internet, Verizon carrier locks the GSM in the states. In other words, they make it so you can use GSM OUTSIDE the US but not allow AT&T or T-Mobile SIMS to be used in their devices. This is a carrier lock, not SIM lock, so they can get around the whole "well, our phones are sold SIM unlocked" bs. After calling a level two tech support, he told me that there is no such thing as a carrier lock or SIM lock, and he could not give me a code. The phone was able to make a voice call and send a normal text, but data sucked.

Sorry to disagree, but my SCH-i545 works on the AT&T network with an AT&T SIM installed.
I only get Edge because that's the only band that VZ and AT&T has in common in this area. Swapping out a SIM isn't going to fix that.
What you're finding about GSM locks applies to pre-LTE phones. The LTE phones are not SIM locked, aren't carrier locked. Period.
I have a strange problem. I bought a Verizon LG G3 from someone and I put my att straight talk sim card in it after verifying with verizon that the imei is clean. It works fine until you restart it then it has no service. It will still have global selected as well as the apn setting I entered. If I make it manually search for networks AT&T shows up but when I click on it to register it to ATT service after a long delay it says it cannot. Also if I select cdma there is no verizon signal either which it had before. If I factory reset it, it will work once more until I power it off and restart it. I've tried clearing the cache partition as well as updating from kitkat to lollipop. Same problem. I have it set up the way I like it now and really don't want to factory reset everytime my battery goes dead. Any ideas??? Thanks in advance, Mike
Another thing I noticed is there is a sim card icon at the top with a ? in it. It is there even when the phone is working.

After updating to lollipop it wont even register on the att network after a factory reset. I flaahed back to 4.4.2 with lg flashtools and still nothing. Also rooted and then installed snapdragon rom and no luck either. Any ideas anyone?

Get a straight talk verizon sim that way it works perfectly and you will get 4G LTE.
They sell kits at walmart just make sure you get the CDMA 4GLTE kit
Verizon doesn't have good service here. The phone also doesnt show verizon signal anymore like it used to.

Straight talkvzw is the best in my opinoin but if you must have ST Att then I suggest trying a different sim. You have to use a 4G SIM in it so if you don't have a 4g Att SIM it won't work. After you get the SIM make sure you activate it then switch to gsm mode under mobile network settings. Then download the straight talk data settings app from the play store and follow the instructions.
GSM mode: settings/ tethering and networks/ mobile network / network type : global>gsm
So the other week i put Lineage 14.1 7.1.1/7.1.0 rom on my samsung galaxy s3. I just switched to virgin mobile uk i was previously with giffgaff and giffgaff worked completely fine on this phone and rom. Yes my phone is unlocked. It was originally on a EE contract then i unlocked it and used it with giffgaff (02). The problem i'm having is when i put the Virgin Mobile UK sim into the phone and boot it up it says "Emergency Calls Only". When i go into the network settings and mobile networks and search for mobile networks it shows T-Mobile UK (EE which is who virgin mobile use), Vodafone, O2 and Three. (These 3 here have a padlock icon at the end while T-Mobile does not. Im guessing this is good. When i tap on it it refuses to connect and just tells me to try again later. It might be worth noting that when i start up the phone it briefly says "Emergency Calls Only - Virgin" at the top of the handset which i assume its connected for a second and then disconnects, loses connection or gets kicked off? I was on the phone to Virgin for 20 minutes and after i told the guy i was using a custom rom he did say it might be possible that Virgin does not allow anyone with a custom rom on the network.
Is this possible?
Has anyone else ever used a custom rom on Virgin Mobile UK, could you connect or did you have problems?
Thanks, Luke.
Have you set the apn settings?.
Beamed in by telepathy.
Apn settings affect data and should not affect voice service.
Only way to test the Virgin rep's assertion would need to flash back to stock and try the sim.

Quite sure my s3 on a custom kernel was once using vermin so i doubt they'll block custom roms from the network..
Without apn settings you might get as far as edge but certainly wont get 2g or higher.
Beamed in by telepathy.
I think flashing a stock ROM and then trying to connect is the only way to eliminate another possible factor.
Ok, i'll try stock rom then i guess. What do you mean "Without apn settings you might get as far as edge but certainly wont get 2g or higher." I don't get any signal at all so that can't be the problem.
Does or can anyone help me find a faster download link or mirror for a UK version of the stock rom. Samsung-Updates download link from rapidgator is so slow. 7 hours *tears*
The only other place is sammobile.com but that may only be a bit faster.

Tried stock rom, still no luck. Any other ideas? The Virgin guy said it could be a very very small chance that its the sim. But the fact it quickly displays virgin at boot up makes me think the sim is fine.
Maybe try the Virgin sim in another phone? Phone shows the correct imei? Not blacklisted?
Yeh I need to try this, literally no one in my family is on EE or anything using EE. What if the SIM does work in another phone what could be the problem with mine? Phone does show correct imei and it can't be blacklisted since it works with my giffgaff SIM.
Have you recently "moved house" from giffgaff to virgin and ported your number?. Your sim might not be activated. Im swinging with that from this point forward.
Text READY to 789678 from your old phone & SIM and your new sim if that doesn't work.
Moved house? Do you mean like switch from! Giffgaff to virgin? If so yes I just have switched. I was planning to keep my number but since I haven't got network I can't and haven't told them the PAC code.
How can I text a number of I don't have single or does that still work? ?
It is possible it's not active but the guy on the phone told me it was, he even got me to tell him the end 3 digits off the SIM to check.
The reason it's possible is because I ordered the SIM from them and the first one that was supposed to be delivered by YODEL was never delivered I called them that evening and they said we will just sent out another SIM anyway and so they did. This second SIM they sent out is the one I'm using and it might be the first SIM that is only active. But the fact the Virgin rep asked for the numbers of the sim and then told me it's active...I really don't know
Regardless, you must activate the sim, try the text i stated, if no joy try to call vm from the new sim and tell them the pac code then they swap the numbers over. If it doesn't ring out then I'd take it to carphone warehouse and ask them to set up the new sim card.
The sim is active as in it is alive and sending a response but it looks like the actual line attached to it isn't active. Sim cards must be activated to prevent the number attached to it from going stale as there is a forever decreasing amount of 07 numbers available for networks.
I'm convinced that the sim isn't activated, it will currently be a payg sim and might need to be topped up to activate it, then you transfer any number and remaining credit to your new contract/payg sim (if required).
You should still be able to call the carrier on an inactive line so long as the sim is alive. Failing that use a landline.

Well i've called virgin again and they say it is active. It has been over 24 hours. I've tried it in 2 other phones and it just doesn't connect. They even sent out a 3rd sim now and same problem. Definitely a problem there end then, i'm thinking?

Did you try the text to activate the sim?. As I said, the sim can be active as in valid to the system but not necessarily activated to prevent the number going stale and being returned to the pool after 6 months on no use.. Even if there is no signal at all you should have at least tried it once.
Maybe the sim is payg and needs a topup to activate. That could be another restriction.
I don't have any simcard documentation so I'm shooting at fish in a barrel but surely 3 sim cards on the trot can't be faulty. Something is amiss..
