Yes great information above.
I went into ServiceMode by pressing *#0011#.
Did an Airplane Mode toggle, and watched the ServiceMode readout when LTE would connect for the brief window then drop to 3g.
LTE would lock on to band25 quickly after turning Airplane Mode off. band25 would sign on and show System: Available go idle after about 45 seconds it would sign on to band41.
band41 would show 'System: Limited' and be idle. Within 10-20 seconds band41 would switch to band26 showing 'System: No-Srv' LTE would then kick into 3g until toggled again.
Could it be different bands doing the same thing around the country, or is it all the same band? Post what you come across.
Thanks JCHERRY9Zero99 for the tip on the S4. I finally have an answer from Sprint. After being on the phone with a tech this morning. They do not know why the device is not working on normal LTE. I was told to return before the 14 days, because they have no estimate of a fix for this issue. They do not know if it is a hardware issue or software issue. They are aware though of many customers having an issue with this device and they are working to resolve it as soon as possible. An admission I can live with.
I am returning the device I dont want to waste an upgrade so I will just sit until they fix the S5 or the Note 4 comes out.
Good luck everyone and I have emailed some tech media networks and have gotten a very positive response from a big one. So I suppose we will have better answers soon.
If this is true, it is nice to hear someone admit it finally. I would like a confession more then being ignored on a blatant issue. I pay for the insurance, so I may just hold onto it and if it is software, great and if it is hardware I am going to make them replace it and I am not paying the down payment. They can't force anyone to buy a new phone that they released broken in the first place. The only frustration is WILL it get fixed or is this going to get swept under the rug in a couple months and forgotten about.
Sprints business practices are comical.
Again, either Sprint devices do not function on its own network, or Sprints network does not support it's own devices
Return your phones, port your phone number to a network that works. This is your typical Sprint donkey show. I'd get out QUICK before they F-U over past the 14 day return day... This is my new mission to make others aware of the "show" they make you watch before they cram in a non working product in your hand for 2 years.
What happens if it turns out to be a hardware issue with how the phone is set up and it is past the 14 day return period? Are we stuck with a phone that never goes to LTE on its own?
