Hello, I also recently purchased a SIM5320A dev board, albeit a Chinese one: https://www.aliexpress.com/store/product/MINI-V2-0-3G-HSDPA-SIM5320A-module-with-GPS-evaluation-kit-evaluation-board/605000_622098456.html?spm=2114.12010612.8148356.2.7a171054vW58eu
After a lot of scraping through their AT command documentation: http://simcom.ee/documents/SIM5320/SIMCOM_SIM5320_ATC_EN_V2.05.pdf
I learned that you set the apn profile by passing: AT+CGSOCKCONT=1,”IP”,”YOUR_APN”,”0.0.0.0″,0,0
for ting: YOUR_APN = wholesale (I think)
then make sure that specific apn profile is selected with: AT+CSOCKSETPN=1
then try pinging google with: AT+CPING=”www.google.com”,1,4,64,1000,10000,255
If you get a result then YAAAY! you’re on the internet!
I also encourage you to dig through the SIM5320 documentation at http://simcom.ee/documents/?dir=SIM5320
Happy hunting!
