Help me please

There is no answer or solution

i am waiting also for update
update on the way

I hope it won't last long

Where are the specialists in this field?

It is funny no one answers, enable roaming, see if this helps

Enable roaming and Network Selection fro Automatic to Manual and choose the preferred Network.

Thanks for trying, but the method didn't work

you need to be running iOS13.3

not work now many times tested wait for update

thank you, I will wait for the next update

No one anwers 'cause it's nothing to say. Only that Rsims are not working. That's all. Enjoy.

If what you say is true (unfortunate)

No reviews for chip sale in last month so pass. Bypass down since August.

RSIM15 not well on some iphone 7 plus 、7 , try RSIM14+ V14.5
