Samsung S3 LTE 4G (Cannot open mobile data saying insert sim to access network s.) - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi i really need a bug help. I bought my s3 Lte 4G in singapore last month. i activated my LTE simcard from globe but when it was activated I cannot open my Mobile Data. everytime i try to open mibile data it says "Insert sim to access network services" I was able to use my H+ signal when i still have my regular simcard and ive talked to globe and they said that they did not released any LTE s3 (Thats why im looking for a way to use this here). I know some s3 LTE users can use their globe sim but it is the s3 LTE unit with the antenna , mine dosent have any. please i really do need ur help. By the way im from the philippines ang globe user.thankyou

Hi,
I also have the same problem. I bought the S3 LTE i9305. I thought it would be compatible with the Globe sim(Philippines) since the S4 works with it. When I used the LTE sim in the i9305 it can be used to call/text but when accessing data/network it displays the "Insert sim" message. Non-LTE sim works fine.
Anyone have any idea on how to fix this?
Thanks in advance.

Usual wrong modem wrong CSC.

I got mine working. I read somewhere that the an update for the i9305 fixes this so I factory reset my s3 and updated via kies. After the update I now have 4G as signal.
Just a question though, my friends with iphone are getting LTE, and mine is 4G. Same service provider. Am I still not getting LTE?

s3 lte help
what should we do? can anyone give us a link on what type of bandwith am i gonna use?

Samsung Galaxy S i9000 on Telus 4G LTE SIM?

I picked up a used Samsung Galaxy S i9000 that was on Virgin (CDMA?). I rooted it, and put JB on it. From another device, I have a Telus data plan that is on 4G. Looking at the i9000 specs, it says it supports GSM and 3G. This where I get confused. The Telus plan I am on is 4G LTE (data). Does this mean that this Sim could fall back to 3G if I use it in my Samsung? I have ran a number of unlock tools (including the Samsung Galaxy S Unlocker) and think that my phone is unlocked, but the radio shows that there is no connection. When I ran the unlocker, it completes but does not say "its done". I can see that I now have the correct APN setting for Telus. The phone sees my SIM and my phone #. And I have the nv_data.bin file ( was not there before running the unlocker). When I look at the phone details, it sees my SIM, knows my phone number etc. It just won't connect. It also has the correct APN settings. If I try to dial a number or use the data, it does not work. Wondering if there are other settings I am missing?
I think the issue is that the sim only runs on Telus 4G and does not fall back to 3G (what the phone is capable of), but again, this is where I am green. I don't know how this works. Does the phone 'ask' the Sim to fall back, or does the network and Sim dictate to the phone what network it will use?
Area of coverage: Burlington Ontario (GTA). Sorry if this has been discussed, but my search terms did not find anything.

[Q] LTE Coverage C6603

I've been using an Xperia Z for a month or ++, Well, It works pretty well and stands out from the crowd with its water resistant feature !! I'm in Sri Lanka and 4G - FDD (Band 3) deployed by Dialog, they said me to update my sim to receive LTE Signal, so I went to their store and bought a LTE Sim(Difference is Ordinary sim is 32KB & LTE is 64KB doesn't matter).... they told me it will get about one hour to activate LTE, so use it we will be activating it... oh yeah after one hour I could see it through a Manual network search for network.... but there is a problem with the phone there is a coverage drop with my phone. It works only after switching on the phone. but I could manually search for network. It doesn't even work with GSM(tried every combination) afterwards what could be the problem ? Operator or My Phone
Note : I tried my other sim as well, those work fine H+

4G LTE not active

I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?
I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.
Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks

What rom did you update to? If you updated to a united States t mobile rom it could give you trouble. I am only guessing but you may do best to install twiztd or another custom rom from here. Maybe even one of the n7 ports.

Samsung note 9 N9600 VZW network issue

Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!
Teddy
