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.
I replied to your Reddit post. But so others here know, it's an issue with eCSFB and IMS on the Airave. Devices which maintain SRLTE don't have the issue, since calls and texts go over CDMA instead of LTE. I have a ticket open about it, but so far they can't find anything wrong. Been a problem that has been ongoing for months, and I know other people in different markets with different devices and accounts have the exact same issue. It affects all phones that rely on eCSFB and IMS instead if SRLTE.
A "solution" is to block the LTE ipsec tunnel on your router's firewall. In my experience, blocking access to 22.214.171.124 and rebooting the Airave resulted in just CDMA and no LTE. That being said, if your non-SRLTE phone can pick up the macro LTE signal at all, it will almost certainly never use the Airave. I don't believe that macro eCSFB will setup a call via the Airave.
