Correct syntax for HTTP Post

This is not exactly my area of expertise, so sorry for what may seem like a basic question.

I can’t seem to get the Syntax correct for the HTTP Post. - myToken is of course replaced with my actual Token.

I’m communicating directly using a Telit LE910 modem.

This worked:
AT#HTTPCFG=0,“us1.unwiredlabs.com”,80,0,0,120,1
AT#HTTPQRY=0,0,"/v2/balance.php?token=myToken"
AT#HTTPRCV=0

This also worked:
AT#HTTPQRY=0,0,"/v2/balance.php?token: myToken"
AT#HTTPRCV=0

The HTTP Post should look something like the following, all variations return an Error.

AT#HTTPSND=0,0,"/v2/process.php?{“token”: “myToken”,“radio”: “lte”,“mcc”: 310,“mnc”: 260,“cells”: [{“lac”: 7033,“cid”: 65960291}]"}",803,2
