How can I tell on field test most on an iphone 5S which 4G frequency I am on??
Open field test by dialing *3001#12345#* in the phone and tapping green.
Tap "Serving Cell Info" and look at "Freq Band Indicator".
The number is the "frequency block" in use - only 3 blocks are in use in the UK so far for LTE (4G), but Ofcom has stated that the the 900 and 2100 frequencies could be reused for LTE; however nobody yet makes phones that use these for LTE.
Number - frequency - used by
20 - 800 - used by O2, Vodafone; and shortly by EE and Three
7 - 2600 - used by Vodafone and shortly by EE
3 - 1800 - used by EE and Three
Each operator has a different allocation (purchased at the auction) of each frequency. The iPhone 5 only supports Band 3, the 5c, 5s, 6 and 6 Plus support all these frequencies and more.
Allocations by band
Band 20 - 800mhz
2 x 5 MHz = EE
2 x 10 MHz = O2
2 x 5 MHz = Three
2 x 10 MHz = Vodafone
Band 3 - 1800mhz
2 x 45 MHz = EE
2 x 15 MHz = Three
Band 7 - 2600mhz
2 x 35 MHz = EE
2 x 20 MHz = Vodafone
1 x 25 MHz = Vodafone
Most handsets can use at most in a single band a 2x20 mhz block, so Vodafone and EE are in a position to run the highest capacity networks in the future based on current spectrum allocations, and Today EE has the highest capacity (ie speed) 4G live network -based on spectrum alone.
and Ofcom are going to run future auctions at the 2300mhz frequency (Band 30).
