Default Which app do you use to scan/debug GSM/CDMA cellular tower signal strength?

I dialed #878# and got:
"Welcome to Verizon Wireless. Your call cannot be completed as
dialed..."


Same here, on the other coast, but with the additional text,
"Announcement for switch [digit] [digit] [digit] dash [digit]."

(Actual digits redacted to "[digit]" for privacy's sake.) Cheers, -- tlvp


I tried it again and got the same thing as you ending in "Announcement
for switch 40-6". 40 is the SID (system identifier) for the San
Francisco Bay area:

http://ifast.force.com/sid
The 6 is the NID (network identifier). These numbers also agree with
the local VZW tower data as displayed by the NetMonitor app. The
phone is NOT activated and therefore shows everything as roaming.
Operator: 310 00 (Roaming)
Type: CDMA - EvDo Rev A
Carrier: Verizon Wireless
SID: 40 NID: 6 BID: 4864
Signal: -88dBm

I have some better phones (Samsung S4(?) and S6) in my palatial office
that I can try later next week.
