Yes thank you we have done this. As stated above, APN for static IP is B2B.static. Works perfectly with 06 model, does not work with 08 model.
Proper IP shows in settings with 06 unit, not with 08 unit. No data passes with 08 model, data passes with 06 model, every time, every unit … (GL-MiFi, Spitz, Amrok)
I have contacted T-Mobile to see if they can give insight from logs or what they have. Waiting response as we asked Saturday.
Seems like one should be able to see these differences in a data sheet but I have not found any doc that shows what those particular numbers represent. Your examples show '04 and '06, perhaps it is a release version?
This is big deal for us, I sold several units with Static IP and now might have to replace units. Need to fix this :[
