Then you have been using old python3 version that comes with OS.
Type python3 in command line and i guess Python 3.5 interpreter start.
Then exit() and type python3.7.
When install with pip3 install modemcmd it will install to Python 3.7(then you most use this version).
Try to install modemcmd again
Then from command line python3.7 ,as i show under here.
Here i use virtual environment that made before, see that both modemcmd and serial works.

>>> from modemcmd import modemcmd
>>> import serial
>>>
>>> modemcmd
<function modemcmd at 0x000001CCDA68D670>

>>> serial.__version__
'3.5'
>>> exit()

Something is messed up.
Requirement already satisfied: modem-cmd in ./.local/lib/python3.7/site-packages (1.0.2)
Requirement already satisfied: pyserial>=2.6 in /usr/lib/python3/dist-packages (from modem-cmd) (3.4)
See that it also mention /usr/lib/python3

And you shall not do pip3 install serial that and other old package(can make trouble) that's not pyserial 3.5
The only install needed is pip3 install modem-cmd(will install also pyserial 3.5)

Don't what to help with now something is messed up other that suggested virtual environment.

# Make 
python3.7 -m venv modem_env

# Cd in
cd modem_env/

# Activate see that it say (modem_env) first now
source bin/activate
 
# Install
pip3 install modem-cmd

Test that i works python3.7 for you

$ python

Can also look at pyenv Simple Python Version Management.
That what i use then it easy to install versions,as Python3.7 start to get old now.
