Interesting acquisition announced today....Blackberry to acquire Good Technologies. For those of you who don't know or are familiar with Good, it's basically a BYOD platform for enterprises. (Email, intranet, etc.) Not necessarily directly Sprint related, but many people use both.
I've seen some threads recently about the differences between SIM/UICCs and though posting a compatibility matrix would help people.
This is pretty straightforward. The matrix has every Sprint LTE device, and what UICC card is meant for that device. Mix and matching UICC card types probably will not work, but swapping around UICC cards for devices that use the same type of card should work properly.
Keep in mind, you cannot simply move your UICC card to another phone to use it. Sprint's device authentication system still requires the correct UICC and MEID to be on the account to authenticate properly and work.
It's hard to make further suggestions without being able to play with your router directly and see exactly what settings are enabled and disabled, or getting a packet capture to see what's happening. Lilotimz's suggestion is probably your best bet for now. Sent from my Pixel 3 XL using Tapatalk
Factory reset your Eero and redo everything from the ground up is what I'll say.
Something about the eeros current configuration is blocking the A4 and just doing these Config edits are not helping much.
So factory reset it to the basics and make sure the A4 works with that. Then slowly add custom settings and rules while ensuring the A4 is operational.
