Have you Sim with a lightning ?
Update your phone too!

Yes, it has a red lightning.

Yes, my phone is dual sim asia version.

I thought it works with any voLTE phone as long as it supports the FIZZ frequency bands.

When 3G is shutting down, I cannot make/receive phone calls, but I'm still able to receive/send text messages and surf the internet, right?

Thank you
