Phone Modes and What it means.
I'm hoping to get a good technical person that can render authoritative information. 🙂
My basic question is this: Does the greater number of modes (combinations of frequencies and technologies) give one phone over another a better chance of getting a signal? As an example: if I use the Motorola Razr M, which has the following modes:
LTE 750
WCDMA 850/900/1900/2100
CDMA 850/900
GSM 850/900/1800/1900
Can I expect it to have better reception than say an iPhone 4S that only has the following modes:
WCDMA 850/900/1900/2100
CDMA 850/900
GSM 850/900/1800/1900
Or worse yet, an iPhone 4 (CDMA) that only has:
CDMA 850/1900
?

No. For what carrier is it?
Mode is only for signal frequency matching that of the carrier.
HTC EVO 4G LTE have this mode:
LTE 1900
CDMA 800 / 850 / 1900
Sprint's signal frequency is CDMA 1900 for voice calls & 3G Data + LTE 1900 for 4G

Frequency
The rate at which a wave alternates, usually measured in Hertz (Hz) - cycles per second.
Also, a location or range (band) on the radio frequency spectrum, such as 800 MHz, 900 MHz or 1900 MHz.
In wireless communication, band refers to a specific range of radio frequencies.
For example, the PCS "1900" band spans frequencies from 1850 MHz to 1995 MHz.
Currently, wireless communication service providers in the US use the 700, 750, 800, 850, 1700, and 1900 bands.
Modes
Many phones are advertised as being "tri-mode" or "quad-band", etc. These refer to the combination of technologies and frequency bands the phone supports.
Examples of modes include "CDMA 1900", "WCDMA 1700", and "LTE 700". There are many other combinations. T...

Each mode works with a certain technology and each technology has it bands, each one of these bands work with a certain carrier.
A phone that has more bands on the GSM mode will most likely be able to roam onto another provider's network. Not necessarily have better signal.
There's something else about what you call modes.

Modes and bands are not the same.
An unlocked phone with more bands will have the chance to work with other carriers if you don't like the service from your provided and want to try something else off-contract.
