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.
My UNLOCKED S-9 can not transmit to the cell site if Band 41 is weak either. It supposedly has HPUE but I do not see any improvement over phones without HPUE. To make it wore, recently the parameters have changed that allow me to hang onto Band 41 and band 25 with a signal of -130. Nothing works at the level, but apparently somebody decided to keep me on extremely poor connections and not allow the phone to drop to a better band. It probably was done in preparation for VOLTE, but it sure has killed my data experience. If I am trying to download an attachment to a G-Mail message, I can not do it on band 41 when being held to very bad levels. -120 was not working and now I find my phone hanging onto -130 level.
Does anyone here have an issue with Band 41 not working well (or at all) on their S10 series device at signal levels of -104 dBmv or worse? It's like the phone can't reach the tower to send requests. I never had this issue with my Note 8 and it worked well up to around -120 dBmv.
I can't help but wonder if my launch-day S10+ is defective.
