Hi all,
Just wondering has anybody come into this issue before?
For some reason, when i use my Vodafone Sim card it gives me the LTE option.
However when I insert another sim card (e.g. my optus or telstra) it removes the LTE option.
Is there such a thing as 4G Sim?
Yes LTE enabled sims

No, it's not sim related, it's contract related. You have to ask to your carrier to enable LTE, and it will probably have a cost.

Hi all, I need help!!
At first I want to inform that I am came from Malaysia. I am using the local telco which only support up to HSPA only. Not HSDPA+.
With my friends which is using same telco as mine (Note 2 N7100), with speedtest apps, he can ping up to 6Mbps++ for download speed. While i am using nexus 4 only can ping about 1Mbps...which was done at same location. I am wondering whether i am getting hardware defection or else...since using the same telco....may i know any method that can be used to test whether i am getting hardware defection on my phone?or sim card prob?
you can buy prepaid sim from same telco to test it,hope this help

You probably have a 9500 model, which does not support LTE. Only the 9505 version does.
No i have a i9505 for sure we only have this model in austria and i have looked at settings its i9505...and also on the box its 4×1.9 quadcore processor

call your provider thewy may have to enable LTE on your account then restart your phone and option may appear as the sim card updates itself ands the phone.

The SIM card may be locked to the device it was activated on. I suggest going to a T-Mobile store to see if they can help.

i tried 3 sim card ... DId they lock all the sim cards?? .. thanks for the suggest i will go to t mobile today
It is likely that they lock the cards to the device that the card is activated with. It seems like it is the only possible reason that you can't use T-Mobile cards.

I went to t-mobile. They tried another sim car and the phones was the same no sim... the said that the problem was with the phone cuz the sim cards are news and working on other phones... i dont know why the problem is only with t-mobile sim cards.. they say that if the phone was from t-mobile they could change me for another phone but it is at&t.... do u you think that it will be any problem if i go to at&t and tell the that my phone is unlocked but it doesnt read t-mobiles' sim cards

They could help. Might as well try. It is a very weird situation. If other SIM cards are working with it, it shouldn't be the phone...
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Yes the problem is only with t-mobile... but i will take the phone to at&t tomorrow

Is it possible that you didn't unlock all the bands on your device? There is a tutorial around here somewhere that shows how to unlock all the bands for use with absolutely any carrier. From my understanding it is different then just unlocking with a code.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Yes but it should said invalid sim car or ask me for that code when i insert t-mobile sim card... but the phones says no sim.. it doesnt even read the sim.... and when u unlock with a code i think is like factory unlock cuz my father unlock his phone with a code and his phone works fine

I have an unrooted ATT S4 and an unrooted Note 3 on T Mobile which is unlocked that I use on ATT.
With the ATT simcard inside the S4 I only receive HSPA and no LTE service, with the same simcard in the Note 3 I get LTE service ( according to network signal info app ). I tried checking my APN settings on the S4 and it looks okay, infact I created another just to make sure.
If I try the *#*#4636 etc etc command the S4 shows WCDMA preferred only. It does not allow me to change to anything else. However, if I put another ATT simcard in the S4 LTE works, anyone care to explain what is going on ? This only started when I first went to review the previously mentioned network radio mode menu command.
Thanks.
I would think you have a bad SIM card. Very strange it would work in one and not the other.

You may have to factory reset the s4
Any luck on that yet? I'm very curious what the problem is with it.

No luck, the unit would only select WCDMA preferred with my ATT sim card inside of it. I did factory reset multiple times to no avail.

No sir, I did not. I have sold the S4 as I bought a note 3 earlier this month. The new owner tested it and he got LTE!

Can't be anything else can it ? I agree.
When the sim was out the S4 would default to its stock radio. I believe it was something like gsm lte auto prn or something.

I had the same issue..it's your sim card....I went to my Fido store...talked nicely to the guy at the counter and he gave me a LTE sim card which he normally charges $10 for....problem solved...if your phone supports the right lte band and the network operates on the same band...it's always the sim card

bs.. i have tmobile and using it on att .. It is not alwlays the sim card. I had to change the apn settings and also go into the menu and enable lte.. it was set to wcdma as max by default.
I've got a 32gb AT&T Galaxy S 4.
I unlocked it using the free and easy method via dialer (works fine for data and calling on Rogers now).
The phone works fine when tethering on AT&T sim card.
But when the Rogers sim card is in, it doesn't allow me to tether.
Is there any way around this WITHOUT rooting?

By the way, the error I get is: "Mobile data is not available or invalid sim"
I am currently connected to Rogers 4G LTE

Sorry to Necro, but on Rogers ... if you have 1GB of data or more ... you automatically get tethering.
man I'm having the same annoying issue. AT&T s4 unlocked by code and I'm using it with Rogers right now. Not only I can't get the tethering to work I also don't get any OTA updates.
