Yes, too many "feebies" is a big problem. Honestly, it would be better to do away with any "feebies" altogether. AJ

Which one is which? If the USCC variant A3LSMG928R4 is any indication, one of these two handsets looks to be another recent Samsung RF turd. AJ

It looks like you are using the Samsung generic engineering screen (*#0011#). You might try the more Sprint specific engineering screen (##33284#) to see if it shows the same weird readouts from other bands/operators. AJ

S4GRU has talked at length on The Wall and in The Forums about carrier aggregation. But some of our readers may have missed those discussions, thus be unclear on CA fundamentals. The following forum post at The Verge is from a Qualcomm employee and is a nice primer written in mostly layman's terms, not overly technical language. http://www.theverge.com/2015/7/7/8909127/carrier-aggregation-explained-how-lte-speeds-can-be-doubled-or-even AJ

The readouts will be "weird." The other LTE signals are out there, but no way will Sprint or the other operators allow you to use those signals. AJ

Reboot your handset. That may solve the problem. AJ

This looks like another case of good old Samsung "enginerring." The PLMN ID is AT&T, but the PLMN name is Sprint. The band 12 EARFCN is in the Lower 700 MHz A block, so that is T-Mobile. The band 2 EARFCN is centered between the PCS A and D blocks, which are licensed to AT&T in Philadelphia. The PCI is the same between the two competing operator sectors -- an unlikely coincidence. And the RSRP is unusably low. Nothing adds up. The title of this thread is off, too. No band 4 in any of those screenshots. AJ

Something is amiss. PLMN 310-410 is AT&T, not Sprint. AJ

Nope. Subtract about 20. http://s4gru.com/index.php?/blog/1/entry-308-rssi-vs-rsrp-a-brief-lte-signal-strength-primer/ AJ

Yeah, but the iPhone 5S is not the best device on Sprint. The dual band build was a half measure. Additionally, the iPhone 5S has PRL and band selection quirks on Sprint. Occam's razor. The simplest explanation is the most likely explanation. This goes back to Robert's suggestion that the issue is with the device. AJ

Deval says, "Hey, I resemble that remark." AJ

Just for reference, Smith Bagley may sound like a law firm, but it is not. AJ

Yeah, the current topic of discussion is on thin ice. Tread carefully, everyone. AJ

Just to make matters clear, this is not a scheduled FCC spectrum auction. This is a private auction. AJ

Everything you posted for your GEO looks fine for our level of work. We do not need absolute accuracy on the roaming priority levels. All we really need are the roaming SIDs/operator names that now have EV-DO ACQ indices associated with them. AJ

Trip, would you be willing to analyze the other GEOs? I have updated the second post again to include now 15 other operators. But PRL confirmation would be helpful. AJ

To expand upon my prior post, I wish that we still had the "Roaming Only" setting. Sprint was unprecedented in offering the setting, and it was useful in certain unusual situations. However, it required responsible use. Sprint still has the broadest and deepest roaming agreements of any domestic operator. In many markets, VZW, AT&T, and T-Mobile provide no roaming fallback, but Sprint provides one or even two roaming fallback networks per market in the PRL. We can only hope that continues. AJ

Not likely. The "Roaming Only" setting was a vestige of the past -- when all Sprint roaming was billed a la carte. The menu setting lingered for several years into the current era -- when Sprint incorporated roaming into postpaid plans. But the latter was part of the problem. People abused the setting. They would pay Sprint to use VZW about as much as they pleased. Or they would intentionally spite Sprint by running up massive roaming usage to parlay a "get out of jail free card" (i.e. ETF free). In short, improper behavior is "why we can't have nice things." AJ

I have updated the second post with a running list of EV-DO roaming networks now in the PRL. Please present any additions or corrections. AJ

I noticed that. The PRL 55025 provenance could be suspect. AJ

Well, I thought you might be alluding to that exact "Seinfeld" reference -- Kramer used butter as lotion and stayed out in the sun too long. AJ

Maybe, but I am no spring chicken. And that is probably a good thing -- with a hungry Robert roaming The Forums. AJ
