I purchased a G13 several months ago and installed it in my 2018 Tundra. Have been very pleased with it overall and am still familiarizing myself with it's features and capabilities.
On that note, I've ventured forth and purchased a data-only sim card from SpeedTalk Mobile which was delivered to me Saturday. I activated it and installed it in the Sim tray for my G13. I waited 24 hrs to make sure that SpeedTalk was able to do their magic to activate it. I even called SpeedTalk Tech support today to make sure that it's fully configured on their end. They tell me it is.
My Dasaita G13 HU doesn't see the installed Sim. I have removed and reinserted said SIM card multiple times. It remains unrecognized my the HU. Pertinent information regarding my HU follows.
