Send SMS messages via Huawei LTE modem API (tested with E3372)

[rextended]

I use Telegram in most of my scripts, I tried it at the time here and I had errors with the encoding of some SMS characters, so I discarded it.

The 2nd function on my post can be used before sent the string (ASCII-7 and/or CP125x) to telegram (UTF-8):

Or directly URL encode the string:
