    Galaxy S4 GT-I9505 Doesn't get 4G LTE

      I have a Galaxy S4 GT-I9505 and it has the 4G option in the network mode. But when it connected to the network, it just shows H or H+ and I don't see the 4glte symbol in the notification bar. I am in Houston, TX. My Friends have a same plan with T-Mobile and they have Galaxy S4 ( different model number). They are enjoying high speed internet 4G/LTE.

      What is wrong with my plan phone? What should I do? I would really like to use T-mobile. Should I change my carrier?

      Thank you in advance for your help.

          That model is not a T-Mobile phone.  The phone has to support certain frequency 1700/2100.  The SGH-m919 is TMo S4 model, yours must be ATT?

          • 2. Re: Galaxy S4 GT-I9505 Doesn't get 4G LTE

            No. It is an international factory unlocked phone. It supports 1700/2100.

              Have you spoken with a rep?  Do you have the GSM/WCDMA option selected on the frequency option?

                Where are you seeing that the I9505 supports the 1700/2100MHz band?  I checked the specs at the two links below and don't show that the band is included.  This would be why you don't see LTE service from T-Mobile on this phone.

                  I am sorry. You are right. It is 800 / 850 / 900 / 1800 / 2100 / 2600 MHz.

                  So, What should I do? Can I have 4G LTE in my galaxy s4? Can I have it by flashing device with another ROM?

                  Actually I don't have a lot of information about mobile network. I really need High speed internet on my phone. is there any way to solve my problem?

                    I am sorry kanehi ! I was wrong about 1700/2100MHz! It doesn't have LTE/GSM/WCDMA option. it has 4 options in the network mode:

                    1.  4G/3G/2G (auto connect)

                    2.  3G/2G (auto connect)

                    3.  3G only

                    4.  2G only

                    I've selected the first option (4G/3G/2G) but But when it connected to the network, it just shows 3G or H+.

                      I don't believe you can root the ROM because the hardware itself isn't there for modification.  HSPDA is fast, it's like a pre-LTE speed, sort of a 4G without the LTE steroid.  Maybe you could trade it in for a new TMO S4 with credit?  Once you paid  the phone full price TMo will unlock it so you can use it out of country but it's a hefty $630 price tag.

                        No, you won't be able to get LTE service from T-Mobile with that version of the S4.  The hardware isn't there, so flashing another ROM won't help.

                          Hello mehdi1844,

                           

                          The area you are in is modernized which is why you are able to connect to the 4G, but the international GS4 you have does not have the ability to receive band 4. This is the band we use for LTE. Rooting the phone unfortunately will not make it possible to connect either as it is hardware not software preventing the LTE.

                            Kanehi,

                             

                            Are you a T-Mobile sales rep?  I have a question for you as well.  Just as this gentleman is referring to, I am thinking about purchasing the S4 factory unlocked version the I-9505 because I do not want the phone to come with all the bloatware.  I would like to also take the phone periodically to Korea and if I live, there, would like to activate the phone there to use it abroad.  I don't think you can do this with the SGH M919 model. 

                             

                            Please tell me what the T mobile versions of the S4 that are LTE supported.  Is the SGH M919 the only model the LTE network will support?  We live in a modern technical saavy day and age, and I would be shocked if that were true. 

                             

                            Why is the I-9500 and I-9505 note LTE supported?  When will T-Mobile bring their bands up to speed?  If I9505 is not LTE, how fast is the 4G compared to the LTE network?  Can you please elaborate?  I need to make my purchase in the next day or two, and your input is really appreciated.

                              The TMobile S4 version is specific to the US which includes all the bands to work with LTE (AWS, 1700, 2100).  If you plan to live in Korea why not buy a phone there instead?  ATT, Verizon, Sprint though they're all LTEs are not compatible with each other as it's all about spectrums.  You can have a US phone unlocked so you can use a foreign SIM card but again it's all about the specific spectrum in order for the LTE to work.  Most unlocked phones from other countries won't work with US LTEs and are regulated to Edge, 3G and rarely 4G use.  I heard Korea is working on a faster LTE than the US but then again might not be compatible with our LTE.  It's all about government regulations on which communication bands a company can use.

                                I purchased an S3 - i9300  with the same basic frequencies as the S4. (no 1700).  I went to a T-Mobile center yesterday and they could not make it connect to their system.

                                 

                                I don't have LTE  and I knew the S3 did not have 1700, but according to the phone sales office it should work.  Is there some APN names that may make this work or  should I just try ATT or return the phone?

                                 

                                thanks

                                  You can ask the sales rep to set up the APN on the phone.  You can go the the S3 forum and ask what the APN settings are.  Here's the settings for my S4:
