No 4g signal - Verizon Samsung Galaxy S III

My brother recently purchased an S3 off ebay to replace his Droid Razr. The reason for replacing the Razr was that he couldn't get any 4g on it. I gave him my gnex to use while his S3 arrived and he had perfect 4g on it. Now that his s3 arrived he has no 4g yet again but is able to recieve 3g signal. Any ideas?
Thanks in advance
also, if this thread is in the wrong place then mods feel free to move it.

Probably should go in q&a since it's a specific question but at least it's not in development
My guess would be it's a bad sim or defective phone. Have you tried to reprovisioning? There should probably be a guide in the sticky by droidstyle or just use the search.

I would try the new sim. I had that once before too. It is weird but I had it work for me.

If you are rooted try different modem/rpm and if that doesnt work see about the sim card. Just make sure you go back to stock before you go to verizon

Maybe start really simple with - is the phone's Verizon account setup for 4G?
If it is a stock S3 you should be ale to make it Verizon's responsibility to make it work.

Global mode nag

Every since I flashed jellybean leak #2. Every time I lose signal it will not stop begging about global mode. Does anyone know how to disable this pop-up?
Devices:
Samsung Galaxy S3 - stock JB leak
HTC Incredible - JB Inc RC3
Sorry I can't help but I experienced the same this weekend when i was out in the country. As you stated it is pretty persistent. I ended up just saying yes then once I got back to having a signal I had to reboot my phone to get rid of the roaming data warning.
I hereby demand VZ to improve their coverage on the outskirts of River Falls, WI. Do you have any idea how emasculating it is to have to tether to an AT&T iPhone to update NFL scores?
Have you tried changing the mobile network settings on your phone to LTE/CDMA.

Phone is unable to activate -- any tips?

Hey XDA -
Just picked up a Galaxy S3 on Verizon and the phone doesn't seem to want to activate. In theory it should have been capable of automatic activation upon initial power up. At any rate, once the S3 is turned on, it just sits at the "Activating" screen forever and doesn't seem to actually activate with the network. I've already tried rebooting and re-setting the SIM in the slot. Do you all have any advice? At the moment I'm on hold with VZW customer support to see if that helps, but if you have any insight, do share!
Cheers!
Sparky
Go to the vzw website and activate there also. That will fix it

You probably put the card in upside down.

Well, for one, this is the wrong section bud. This is for the Verizon version, nothing else. Secondly, you can't use 3g and talk at the same time.

[Q] SIII Global mode Grievance

So to begin my problem, I have a SIII which is a wonderful device but since i don't root my phone anymore, its causing me a pain as to fully using the phone globally and not being able to use the Internet, , and i was wondering if there are anyone in the same situation as me. and was hoping we could get a long chain of complaints to the BBB so that verizon may unlock the feature which should have been present from the future! Maybe i am asking for too much, but if there are people with similar problem, then maybe we could see some action taken by verizon and actually be able to the phone in the US and abroad too!

From my experience you need root to change the APNs for data. why don't you just root? shouldn't be to hard

I'm not sure that it was Verizon's decision. In any case, since it may be a while, you may just want to root. I'm overseas now and it wasn't hard for me to change apn's using apn manager pro. I set it as a system app first in titanium backup.

I think only the Verizon S3 and Verizon Note II has these issues, all other phone APN's can be changed without root!

This is for the Galaxy S 4G, not the Galaxy S4!!!

GFX.myst. said:
I just have one question for you guys. Are you using a Galaxy S 4G or the Galaxy S4? If it is the latter, please take your questions
here for T-Mobile
here for Verizon
here for Sprint
here for AT&T
and here for International
as this section is for the Galaxy S 4G. Thanks and good luck.

So I created this thread because it is way too apparent that the new S4 users are too lazy to look at the name of this section of the site and keep posting questions here about their S4. I'm hoping this gets stickied in each section of the Galaxy S 4G Forum in hopes that they might see that they are indeed in the wrong section. Thanks in advanced.
Don't worry, it's almost guaranteed they won't see it so just be ready to copy and paste
Lmao I have an s4 from verizon
But I still put out roms for the s4g lol

What do we need to do to try to get this stickied? Hopefully in all the SGS4G forums, but at least in this one?
We should just rename our phone. How about the Samsung Galaxy S H, since it doesn't actually have 4g
Galaxy S GGGG
That'll be fairly obvious.
Galaxy Ass for G
