No LTE - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

I purchased a galaxy s3 I9305 today. I have rooted it and installed supernexus. It all seems to be going well but now when I go into the network settings and choose LTE/WCDMA/GSM, as soon as I exit it reverts back to WCDMA preferred. I am in LTE reception. The only thing I can think of is my sim card. My sim card is almost 7 years old, I had to cut it down to fit the s3. I have read varying things regarding 4g sim cards. Could this be the reason?

Hmmm... try and change sim card from your operator? Maybe 4g sim card is different?

have you checked your APN?

I have used the APN from the virgin website and still no luck. I have been searching the forums to see if there was a difference between 3g and 4g sims. Most people say there aren't but I have heard that any sim older than 5 years won't be 4g ready. Is this correct?

Your operator must provide you with a new sim lte enabled. But to be honest 4g isn't a big deal, I have my i9305 still on 3g. Cheaper and longer battery life at the price of a slower connection, but most of the time I'm on a wifi.

i have heard of those rumors too... but i heard that if the sim can support 3g, it can support 4g.. give virgin a call? maybe they need to activate the 4g service on their side?

i'm from singapore so our 4g service is an add-on. to get 4g, we have to pay a little bit of extra money and our provider will activate the service for us..

Definitely change your SIM card. Some operators give a 1-1 exchange for free. Just show them your phone and they should be quite happy to change your sim card for free especially if your plan is 4G enabled.

[Q] About htc vivid and new Sim's

I just got an HTC Vivid in the mail today and i have an old Cingular Sim card that's capable of achieving the H+ technology in for example the htc inspire. Now since i live in Portland and there is no LTE yet only H+ why when i put my card in it will make and receive calls and texts but not let me connect to data. Note this is stock ics that the phone was shipped with.
My question is why cant my old Sim work if it can use H+ on my inspire but not on my vivid and also whats different about the newer Sim's then older ones?

this has been asked before and it seems to have something to do with how new your sim card is...mine didnt have to be changed but provisioned for lte
and some have had to have theirs replaced.. here is the thread that it was it was talked about in

The Vivid defaults to using the pta APN. The old SIM cannot connect to pta. You can manually make a legacy APN for wap.cingular or phone which will let you connect, but that's inadvisable.
I'd presume that the reason that a new SIM is required is because you're moving from a 3G technology to a 3-4G bridge technology. I don't know if you have the original Cingular GSM "64k SmartChip", but I had to upgrade that when I first got a 3G enabled phone.

No, that's a 3G-enabled SIM card. It works on UMTS and HSPA, unlike the 64K SmartChip (the GSM SIM) that I had from when EDGE was the best thing since sliced bread. That's why you never needed to upgrade your SIM when faux-G hit on the Inspire.
When I upgraded to the SYNC (see sig), that was right before Cingular was bought by ATT. I had to get a new SIM at that point, and they gave me the one you describe. I had to get another one when I got the Shine, as the contacts on it had corroded (or something; the card refused to read); that time, I got one that said AT&T on it (it was a palette swap of the Cingular card). I was still forced to upgrade yet again when I got the Vivid.
im just going out on a limb here, but i would say it has to do with the apn settings since you have an old cingular sim in a new phone im guessing the apn has been updated for new technology advancements

APN settings are stored in the ROM, not the SIM. The SIM authenticates you with the APNs that it is provisioned for.

I work for At&t, they lie about their data speeds. So basically, the phone might display H+ when your signal is really strong on 3G networks; the OTA updates on the Inspire wanted to make you feel like you were part of the fastest network At&t had to offer at the time. So if you didn't have a 3G sim, you were robbing yourself on speed capabilities, maybe barely but none-the-less. But Cingular SIM cards can only connect to 3G speeds at max. In other words, you're at the max speed for 3G which prompted the phone to display an H+ icon. The Vivid is an LTE capable phone and needs a SIM card with LTE capabilities in order for data to work, even though the new SIMs will also work on 3G, but not the other way around on cingular sims. Oddly enough, you will see a 4G icon when you're maxed out on HSDPA even though you may not be on true LTE networks...as is the case where I live. Hope this wasn't too confusing

I see what you mean everyone yea i actually went in the other day to a store and got a new one for LTE even though there is no LTE in Oregon yet. But i do understand because i did use my Cingular Sim in my vivid and calling/texting did work fine just the data did not work so pretty much for faster internet you need a Sim card that can be provisioned for LTE is what im hearing. Also for the newer tech you need a new one
You can add another APN setting very easily until you can get a new LTE provishoned SIM....THE NEW APN will give you 2g, 3g, HSPA+, Text and Voice....then when you get the new LTE Sim...you can go back and set it to the APN that is named pta....
Let me know by replying if you need the settings for the wap.congular APN and I will post...

Thanks for telling us what many of us probably suspected. I have always thought that most of what we are told is just "marketing hype" until proven otherwise. Much like the burger commercials tha make the subject look soooo tantalizing and huge when in fact it might taste great but is not THAT large.
It is nice to have someone on the inside share "reality" with us!!!

[Q] LTE sim card, any benefit?

Hi everyone, my network has recently upgraded and has LTE sim cards available. I know the n7000 is not a LTE device but is there any benefit to using the LTE card? Just curious as it is a microsim and I would need to get a sim adapter to work in the n7000.
Thank you for any insight!
Since the Note doesnt support LTE, i very much doubt the "LTE" sim card will make any difference.
But if they are being offered to you for free, take it. its not gonna make your phone self-destruct or anything
my friend has an lte phone. the intenet is very fast but he said he wouldnt buy again an lte phone because its unnecessary.
well when i run it with basic settings its ok but when i add the att pta settings to mine it does run much faster.... you do have to have att's system thinking you have an att note and not the international one. might not be lte speed but mine goes pretty fast...
if you get an LTE sim card in Note 1, you are cued up to get LTE service when you switch your phone to an LTE phone.
I'm thinking of getting one. $9 for the card, I cue myself up for LTE when I get an LTE capable phone. In the meantime, I still get the same quota of 6gb for the same price but now I have LTE.

What speed do you get? I get on average 11-12mbs on hsdpa +. More than happy.
from the man hiding in your attic....
Where are you and what carrier to get 11mbps on HSPA+? Im in UK on 3 and get 8.

a little story from my country, in Indonesia, if we not in big city, like jakarta, yogyakarta, or bali, it's only get EDGE signal man, it's suck(sorry).. if i can get the HSDPA signal for a while, it really make me happy, and after that or you go to another place or go iside house, you go back to EDGE.......
I wonder how fast LTE is, and network on your country, someday maybe, thanks for reading..
I'm not into lte, at least not now since lte coverage is limited to a few cities in my country (Switzerland) and the prices are still far too high. Maybe in a year or so when the coverage will be better.
Back on topic: No yiu wont benefit from a lte capable sim card if your phone does not support lte.

well my sim gives the cingular 410 apn stock when sim inserted and it gets 4-6mbps... when i change it to pta settings i get 13-17mbps... it works because att's comps show me having the att ver. when it shows unkown it doesnt go any faster than the 410.... and no i didnt steal a imei... just made a dummy that att comps like and think is a working 717...

First upgrade with Sprint - SIM card?

It looks like it has a SIM card, is new to Sprint? I guess it don't matter as no one else uses the same frequency as Sprint. I did not think they had them. Charging the battery now and was wondering how the switchover from the old EVO 4G to the One will go. I saw some popups on the EVO yesterday that looked like they were messing with my account. Was wondering if both phones would work for a time or if I call and activate the new one. I’m guessing call to activate but just thought I’d ask and see.
Found the Sprint Upgrade Instructions. Wish they both had SIM cards I could just swap.
You have to call to activate with sprint unless they have a new automated setup now. *2 is all you need though.
The sim card is specific to just lte its included in all lte CDMA phones now. The activation process only requires the serial number for ur phone, I'd recommend checking on the phone itself instead of the box as some evo lte units came with the wrong box, after u have the number u can call via a different phone or do an online activation

The SIM Card is not just specific to LTE. The Sprint ONE is also a "World Phone" meaning it works for voice and data over seas. Most likely it has been guessed that it has GSM 900/1800mhz capabilities.

HTC ONE Developer Edition Not Connecting to 2G network In India

Hi All,
I am using two Units of HTC One Developer Editions. With one handset the problem is it's connecting to 2G network. 3G works fine. I tried with MTNL sim and it worked and after that my first SIM which was not connecting to 2G also worked and after couple of hours situation came back and now the unit is only working with 3G network. Is there anyone else facing the same problem ??:crying:
Does anyone have any solution for this ??
Regards,
Mahesh
EDIT : After Doing S-OFF , now my handset it connecting to both the networks i.e. 2G and 3G
Thanks Moonlight Team ReOne Team

because In india there are some places where we do not have 3G connectivity..
It might just be wonky signal in your area for 2G.
Also if you are using hand cut old sim, just get it changed to proper micro sim from MTNL. I had similar issues with SGS4 and MTNL Mumbai sim until I changed the sim card itself. Hard to explain but it solved my issue. It was very old sim which I cut using sim cutter.
Not facing any issue with 2G signal at all. There are areas in certain areas where I have to go (mainly basement) where there is no 3G and 2G works just fine on EDGE.

So you mean to say there is no problem with the handset, cos it worked with MTNL. ??
But it's not working with MTNL and Airtel.....and yes Airtel SIM is very old i mean it's around 3 years old sim.

The sim card issues in cases of cut sim cards is well documented to be honest. No matter how well we cut it, sometimes they just dont work right on these newer phones. Over last 1 year I had to get new micro sim for most of my and my family member's numbers as one fine day the cut sim will simply not catch network and then realised the common problem with them all. All of them were cut either using micro sim template by hand or using sim cutters. After getting proper micro sim, the problem went away. This is not specific to One but happens with lot of new phones that require micro sim including Nexus 4, SGS4 and Nexus 7 3G tablets.

Real problems with download speeds

I have good signal. This doesn't seem to be an issue but my download speeds are woeful. Either 3 or 4g it's just terrible. Ping speeds are slow and download speeds on 4g are less than 1meg at times.
It's a 1052 model. Does anyone know if there's any update modem drivers. Genuinely can't handle this hahaha

Ping and download speeds are most likely related to your carrier and not your phone - especially if you have a good signal. Do you have another GSM phone that you can place your SIM card into and see if your speeds increase and your PINGs decrease? You really need a basis for comparison.
not another 4g phone mrs has an iphone .... but thats only good or a 3g test
might have to just buy one and see what happens... doing my head in though !!!!!
I started a similar thread a little earlier than you. Same crap.

Are you manually forcing the phone into "LTE Only" mode? This would explain why you can't make calls on 4g....
