I have reached out to support but I was posting here if the community might have a fix? I’ve done all the obvious things like restarting, activating the service, and making sure it’s properly inserted . I also tried on another device and the sim worked just fine ---

hmmm, strange my tello sim works just fine maybe ask tello to send you another SIM, i realize you said it works in another device, but I have had a sim not work in a tablet once but worked in my phone just fine and swapping the sim with a new one worked. so it might be worth a shot 🙂 ---

Did you activate the Sim in another device so it can get updated then once it’s running put it in the r1. I had to do that with my Lebara Sim. I activated it on line and in my iPhone then once it was registered ioved it over to r1 works great. ---

My tello sim works flawlessly. Maybe you didn’t input the IMEI correctly? ---

Yes … Tello can see it on their network ---

It was activated on the R1 first… my incoming replacement sim I will do first in a iPhone ---

I would bet it will work after that. Depending on how old a SIM is, certain radio frequencies are not longer supported, in such cases the best choice is always to get a new SIM. ---

I didn’t have to submit an IMEI just the activation code that came on the sim card and put it in the R1 and boot it up.
