I completed my Ringo with 4G SIM model without issue, upgraded the firmware via wi-fi, inserted the Ting SIM, and am unable to make a connection. Thinking that I forgot to activate the SIM card, I went to the Ting website, but could not activate the card. Upon contacting Ting customer service, I provided them with my SIM7600A (no, it has no -H) IMEI number, and just received an e-mail back stating I needed to upgrade to a 4G LTE capable device, as they would not support 2G/3G beyond the end of the year. I thought the SIM7600A was 4G LTE? I then went to the US FCC site, and input the FCC ID from the SIM7600A module, and was surprised to find it was not registered by the FCC (using FCC ID UDV-201709 as printed on the SIM module.)
I normally use AT&T as my carrier, and put my AT&T SIM in the Ringo - still no connection. It just sits forever saying “loading” on the main screen.
In looking over the forum messages, I don’t see much in the way of solid evidence the SIM7600A SIM module works consistently in the USA. I’m near a fairly large city (Los Angeles) and have had no success trying various locations with good signal strength.
Anyone have any thoughts?
