An SVLTE tri band, an SVLTE tri band, my kingdom for an SVLTE tri band! AJ

No, eCSFB and CSFB have the same function -- the former is just the "enhanced" version. To be clear, CSFB stands for Circuit Switched Fallback. And it is necessary only on single RF path handsets, since they must drop from LTE to W-CDMA or CDMA1X to receive a voice call. On SVLTE handsets, which require dual RF paths, CSFB is not relevant, as those handsets can maintain simultaneous LTE and W-CDMA or CDMA1X connections. AJ

No, you do not tell the sharks that blood is in the water. Would T-Mobile's John Legere actually tell small market people that they are going to be stuck on GSM for years while their large market counterparts have been updated to W-CDMA then LTE? Nope. The same holds true here. I feel confident that Sprint was aware of the eCSFB issue but hoped that it would affect as few subs as possible, further knowing that the issue would subside as deployment progress continues. Mitigation. Hope for the best. Sprint has little else that it can do at this juncture. AJ

I think The Dave might have a SIM issue. He even reported that he got a warning about an "invalid card" on one of the two handsets. I am surprised that he did not investigate that further. If the SIM is not seated properly or dead, then LTE will not work. AJ

Prior to Network Vision, Sprint's legacy infrastructure vendors were Ericsson (Nortel), Alcatel-Lucent (Lucent), and Motorola. As I recall, only Puerto Rico had Samsung infrastructure, and it may have even been replaced due to problems. AJ

Yes, that could be a contributing factor. The Galaxy S3 has both SVDO and SVLTE capabilities. We do not entirely know how these tri band, non SVDO, non SVLTE handsets will function in comparison/contrast. Our sample sizes are simply too small at this point. So, we have to observe now, reserve conclusions for later. AJ

CDMA1X 800 is not intended to be every Sprint user's sandbox. It will be there when you need it. If you can access CDMA1X 1900, then you do not need CDMA1X 800 at that moment. AJ

These non SVDO, non SVLTE handsets are always going to fallback to CDMA1X while in call. There will be nothing "higher." So, can you explain a bit further? AJ

Color yourself mostly purple... http://s4gru.com/index.php?/topic/517-nv-sites-complete/ AJ

Right. And this "purple" hypothesis is what we want to test. Scientific method -- you will not find that at a lot of other sites. But S4GRU holds itself to a higher standard. We hope that is why you keep coming back. AJ

Yes, I did see the exceedingly informative insider info posts from both halcyoncmdr and fuunkychicken. What we are attempting to do is corroborate that info with real world experience. If the correlation is strong, then we can go to press with a solid explanation. S4GRU prides itself on providing accurate reporting. AJ

The size discrepancy between the micro and nano SIMs is irrelevant. Even if you cut down one SIM or use the appropriate adaptor with the other, Sprint does not presently support SIM swapping. It might work between iPhone 5S/C models but not between/among any others. In short, for at least the time being, leave the SIM card seated in each device and swap by calling, via chat, or online. AJ

Yes, I fully agree. But we need evidence to substantiate such a claim before we post an article. We are currently trying to gather that evidence via user submission in the just opened LG G2/Nexus 5 issues thread that I linked a few posts above. AJ

Ah, yes, please include in the report your chosen handset -- and if you have made any modifications or configuration changes to it. I will make the appropriate revision to the top post. AJ

The thread is open. Start submitting your reports. S4GRU is on the case... AJ

Announcement: In anticipation of potential evidence collection and discussion, I put in a placeholder for a Nexus 5 LTE issues thread a few days ago, then hid the thread. I will unveil it again in just a moment. It will be retitled the LG G2/Nexus 5 LTE issues thread. It may even expand to include Samsung and HTC tri band handsets. We believe now that the issue has been pinpointed to be an eCSFB conflict between Network Vision and legacy infrastructure in certain markets and on certain sites. Stand by... http://s4gru.com/index.php?/topic/5001-lg-g2nexus-5-lte-issues-thread/ AJ

As S4GRU frequently points out, the site near your house should be basically the least of your worries. A mobile phone is for, well, mobility. This network fallback/reselection issue affects only LTE data. That should not be a problem at home because you should be on Wi-Fi at home. So, even if you use your mobile phone as your home phone, voice is not affected. AJ

Have you attempted to check your order status on Sprint.com? http://www.sprint.com/personal/wireless/order_status.html?INTNAV=ATG:FT:OrdStatus AJ

For the better, or for the worse? AJ

As a friendly reminder, please read back at least a page or two in a thread before asking a question. It may have already been answered. Yep, we addressed this one two days ago. As Mike might say, "Here at S4GRU, we got some wicked 'smaht' kids." AJ

Yes, otters love to eat shellfish and LTE. AJ

Now, your son is going to go out into the world and not know what to do because you failed to teach him about the birds, the bees, and cosplay. AJ

About 90 percent of the population does not care to know when, where, why, how -- they just blindly want it to work. So, our potential audience is limited to roughly the 10 percent that actually seek to understand wireless networks and make informed decisions. And of that 10 percent, seemingly 90 percent are male. Well, do the math... AJ

Need I point out that your username is cosplaygirrrl? If you cannot roll with the punches of cosplay jokes, then you should probably choose a different username. S4GRU has some of the most technically astute individuals that you will find anywhere posting about the Sprint network, but we also like to have some fun along the way. AJ
