Viettel, GN and the beast!

Hello all, long time lurker first time poster. First off this post is going to be pretty long, I apologize, but I think it's necessary to explain my situation in order to receive the best help I can get. For the tldr version skip to the bottom...
My first experience with Android was on a Huawei Ideos U8150 in late 2010. In California I used my Ideos with a H2O Prepaid SIM (no data). H2O uses AT&Ts network. The phone worked great! I loved it. I used Wi-Fi for my data and all was well. Fast forward a month or two and I moved to Vietnam.
In Vietnam I used my Ideos with Viettel. However, EVERY SINGLE TIME I put Viettel SIM in the phone the stock dialer app would crash and crash and crash. I was dumbfounded, WTF is my phone dialer crashing. I took the phone home and began to tinker with it. I discovered a few things after some time.
1) If I shut down, put the Viettel SIM in the phone and turned it on. The phone dialer would force close.
2) Then if I put the phone in Airplane mode the phone dialer app would stop force closing.
3) If I then shut down (while in airplane mode), wait a minute or two, turn it back on (it's back in airplane mode), wait about 10 minutes, turn off airplane mode, the phone dialer would NOT force close and actually get a signal! (If I waited only a minute or two after turning it back on it would still FC)
I was relived, I figured out how to get a signal! But it was a pain in the ass having to repeat the process. I lived with it for about a year. In that time I subscribed to Viettel 3G and the phone was fine. What does this have to do with a Galaxy Nexus? I'm getting to that part.
Yesterday, I picked up my brand new GSM Galaxy Nexus! I was sooo excited! I opened the box, admired my phone, popped open the battery cover, slid in the battery and SIM, turned on my phone and my excitement soon turned to frustration! The same damn problem!! The dialer kept force closing! I didn't think much of it since, hey I figured out how to get it working on my Ideos.
I repeated the process on my Galaxy Nexus and... it... did... not work. So now I am at a loss. I have no idea what to do now. I tried using my wifes SIM card (also on Viettel) on my Ideos and it works just fine. No voodoo dances or anything needed to get it working. I didn't get a chance to try her SIM on my Nexus but I will definitely do it as soon as I see her later tonight.
So now my only guess is that my SIM card is "bad". Can SIMs turn out bad? Can anyone shed some light? Does anyone have any tricks or tips for me? My Ideos stopped working correctly (touchscreen is wonky). So I would like to get my Nexus up and running as soon as possible. My wife suggested we go to Viettel and ask them to replace/exchange my SIM.
tldr: My Ideos with a Viettel SIM keeps crashing the stock phone dialer. I tried other Viettel SIMs and it works fine. I figured out a process to make it work. I picked up a Galaxy Nexus and my Viettel SIM again crashes my dialer. My process doesn't work on my Nexus. Suggestions?

OK, so I borrowed my wife's SIM and it worked on my Nexus. Needless, to say I was sure the culprit was my SIM. It's funny because it's been like that since day 1 on my Ideos. Anyways, this morning we headed down to our local Viettel office and transferred my SIM account to another SIM.
I popped the new SIM in and it works wonderfully. I guess this ends my "1 year saga". If I knew it was this easy I would have done it a long time ago on my Ideos.

Did verizon change their 4g provisioning?

I recently damaged my nexus. I activated a droid1 temporarily. I received a replacement from asurion. Activating was done online. I was sent a brand new sim card. I remember specifically in 2011 when i got the gnex brand new, I was having issues with it. So i reactivated my old phone (droid 2) . Well when I was troubleshooting the device I was informed any time you switch from a 3g device you cannot go back to that sim card it is bad. Yet I was just able to switch from a droid1 to my new gnex with my old sim card, from activating online. Weird huh?
Also weird, upon reactivating my data package received a discount and I am not the primary line.
Any input would be appreciated.
Also, I thought this time I would be running stock, not unlocking or rooting. But its already been 5 minutes and I cant even download skype for ****** sake....

Well good sir, a few months ago, Verizon got tired of shelling out for new SIM cards every time someone went from 3G back to 4G... So despite what it says you can reactivate an old SIM card.

[Q] Unable to detect sim card

I bought my note 4 on launch day. Ever since then I've had an "unable to detect sim card please restart phone" error. At first it only showed up once every few days, but now it is getting more and more frequent and is happening multiple times a day. After reading starting the phone works fine for a while. I've done everything I can think of (pulling the battery, pulling and re inserting the sim, cleaning the sim), but nothing helps. Anyone else having this issue, or know of a solution? Thank you.

I am having the same issue. Not sure of a fix yet but it is getting more and more frequent which worries me.

Same here. :sadface:

Same here! Anybody contact Samsung or Sprint about it?

Same here!!!

Just got my note 4 from Amazon.com. I had been reading about the lte to 3g call drop issue, and someone posted using there sim the card from the phone they were replacing fix this issue. So I put mine in from my s4 before i even turn it on for the first time. The phone worked, but was unable to connet to the 4g (lte / spark ) network. 3g worked fine. I got the message you all are getting (no sim, restart device....). It would happen like every 10 minutes. Once I put the sim that came with the phone in , all my problems went away. Long story short, you need another sim card.

I just called sprint and they are sending me another SIM card. It happens from time to time, but they did tell me if it continues, I can get it replaced for no charge.

This happened after my sim card swap. It would say "network did not respond in time" then "could not detect sim" then phone would reboot. It did it three different times. Then connection became stable and has not done it again. Not sure if these issues are the same as whats happening here. Just posting my experiences.

I actually bought 2 N910P. I planned on making a little extra money by selling 1 of them, but didn't count on the N910P being so easy to get, so I've held onto the other one for a back up until I found a ROM that I wanted to run on it. Well, I found a awesome ROM & booted up my 2nd N910P & got the message you have all mentioned. I thought it was strange, so I rebooted & got the same message again. After doing this a few times, I thought why not take my SIM card from the 1st N910P & put it in the 2nd N910P. I still got the same message after doing this, so I swapped them back before it messed up my primary SIM card. @Yoshi1221, please keep me/us updated if the new SIM card works for you. Has anybody else got a new SIM card? Also, after installing the 2nd ROM that I was trying out, the fingerprint scanner stopped working. I went back to stock & it still doesn't work, so I made sure that I did a full NANDROID backup on my 2nd N910P in hopes that once I get it working & the fingerprint scanner stops working, I can go back. Anyone else had this trouble?
Edit: I tried to activate my new GN4, but the DEC & HEX numbers were not recoginzed by Sprint.com. So I went into chat & they informed me that it had been turned over to technical support & to contact them again after 24 hours, so we'll see where it goes from there.
Update: Chatted with Sprint & the lady activated the SIM card after giving her the number. Hope this will help out. Just go to Sprint.com & click on the chat button.

Looks like new SIM card is working, but just got it today, seriously had to give up an arm and leg in order for sprint to send me one, but so far it looks like it is working, but just got it today, lol

Cool, glad it work out for you.

Also found out from a supervisor in the U.S that sprint is now selling GSM phones now. If you take out the SIM card and only receive 3G, you have a GSM phone, if you take out the SIM card and have spark/LTE, you have a CDMA phone

I had this problem. Sprint sent me a new sim. Fixed the problem for a few weeks but it has returned. Anyone ever get this figured out?

Sim card not found
I had forgetten about this error. Saw that someone suggested a piece of paper between the sim and case cover. I had this happen with a phone I got off a forum. Sent it back and got a replacement. The paper, no matter how thin or thick may or maynot work, and only for a short time. Changing the sim might not work either. You may just need a new phone. I went through all with a s4. Now my note 4 is doing it. I thought it was my recently deceased (July 4) mother was messing with me. One more errand to add to my list for today.

same here?
help plz

Any successful SIM swaps currently?

Has anyone been successful shuffling SIMs after being hotlined, and currently having Verizon service? I'm assuming Verizon notices any SIMs activating in the N7 pretty quickly, but hoping I'm wrong. Anyone?

I have been hot lined 3x. 1st time I waited a few days and activated with no problem. 2nd time when I went to activate, the sim wouldn't work. So I clicked Verizon's "free sim card delivery" button and had a new sim sent to me. It came I popped it in and voila my n7 was back in business. The 3rd time was only a week ago and after I realized they hot lined me again I called had my n4 activated, hung up, and reactivated the n7 I'm using now without problem. Will this happen a 4th time? Probably. But not for a minute at least, so no they won't notice right away if ever. And nothing to stop you from doing what I did.

Thanks. That's exactly what I was looking for. I have my previous phone activated after being hot lined, and am using N7 with a prepaid carrier, but the service is severely lacking. I was thinking about putting in the previous phone's Verizon SIM in, but don't like the sudden de-activation that happened originally, especially if it might only be a day or two. Also was not aware of the free SIM card on Verizon's site. Good to know. Will definitely re-SIM my phone this weekend!

Rooted P3aXL, I reset wifi/mobile/bluetooth, now no LTE and APN won't stay!!

Hey all - long story short, my upload speeds today topped out at .13MB/s, so in desperation I called Verizon, who did some resetting on their end and talked me into resetting my wifi/mobile/bluetooth, which is in settings/system/reset options.
Since then, I've had no 4G and nothing has brought it back. Just did a factory reset and STILL nothing!!
Interestingly, when I open up my APNs, there's only the Verizon one, but it's never selected - even if I select it, still no LTE, and after a reboot it's unselected again. Also with this phone seems I can't edit or add APNs.
I am *absolutely* out of options - really figured the factory reset would take care of it!! I would be most grateful for any help you can give! Thanks in advance - can't tell you how much I appreciate it.

So fun story - on a whim I put the SIM of another 4G phone in, and works like a CHARM. So somehow resetting the wifi/mobile/bluetooth fried the SIM! I think I got one for free at the Verizon store last time this happened, so I'll head there first thing tomorrow!

So you put the SIM in another phone and it worked fine? I am pretty sure you just proved the SIM is fine and the problem is in the device, or it's configuration...
I have been through a dozen phone on one SIM, never had a SIM fail and I have only replaced it when changing carriers. Odd that this happened to you, and happened at least once before...

Nope, I put another phone's SIM into my phone

But you put your original SIM into another phone and it worked fine in another device? Or am I misunderstanding?
I am not trying to argue here, just understand...

No, I never did - I didn't try my SIM in another phones, but I did take the SIM out of my girlfriend's phone and put it into mine, which then immediately got a 4G signal, so I knew the SIM was the issue. Ran to the Verizon store for a new one, and the guy there said "whoa, that's a really old SIM" and I had to remind him what a SIM cutter was - I've had it a while
