PRL

[BryanM12]

Ok I have a I UICC unlocked Samsung Galaxy S7 for spring I use it on T-Mobile network and it won't let me update the PRL. So I can't use the hands free or my aux jack does anyone know how I can update it or bypass it anything

I recommend reaching out to your carrier. They can help with pushing updates through.

So the phone is a sprint model of S7, correct?

It is sim unlocked and you use it on T-Mobile, correct?

I don't get the main issue you are experiencing.  Does the phone connect to the T-Mobile network properly or there is an issue with that?

I have data and SMS and MMS work I can't use my hands free or aux cord for headphones and radios

See if you can flash the firmware of the device to T-Mobile.  Look on xda developers forum

Solved UICC Issue

In late September, My phone updated. Then this annoying popup started. T-Mobile finally admitted their system upgrade for 5G was the issue and I should get a 5G phone. Not! Their upgrade is incompatible with Samsung''s SIM authentication.

This is collusion for sales.

Then on Election Day, T-Mobile starts another upgrade. I couldn't send texts for 36 hours on top of popup. They told me to be patient. Sorry. 2 problems too many.

Solution:
New SIM
New Carrier AT&T
Same Phone S8Plus
No Problem
