VoLTE not working on a Vodafone prepaid SIM

[Jonas]

So, I have a Redmi Note 4 and a Vodafone prepaid sim. If this issue is related to the phone or the Vodafone network, I really don't know.

If I put my sim card in a different phone, like Samsung it shows VOLTE, but it doesn't on Note 4. I have tried changing the region from India to Bangladesh, and vice versa. didn't help. If I put a different Vodafone sim in this phone, it shows VOLTE.

Installed this app and it shows this:

What to do?

That surprised me too!

@Chip I asked them this 2 years ago when I got a new Vi sim from our old Hutch sim. They said it's for security purposes... Don't know why but still...

 

[Jonas]

Is this why criminals like me prefer Airtel?

@havoc @Samuel frankly I consider VI stupid. I am not sure what security threat VoLTE can pose. Though I am on Jio now, thing is, I have history going back decades with both these providers. Idiocy still prevails. No wonder these 2 are in the shape they're in today. And coming to speeds, Jio is faster..tested on the same handset (dual SIM) at the same place i.e. home.

PS - Airtel is faster too but different handset. So, VI and 5G? HAH!

@Samuel I wanna join you too then

Don't know why but Jio sucks in our area then Airtel and Vi leads them all. And about BSNL they are before jio.

I have no clue why people in India think 5G is gonna be a game-changer considering the pathetic state of 4G itself and the serious lack of spectrum handout by the government which they are again doing the same mistake in the 5G sale too.

@Lolita_Magnum Fully agree. 5G is slated to be another disappointment. Only the Govt will be happy getting 10s of 1000s of crores as spectrum fees.

I already knew all this by 4G point as well as when our telecom minister tried 5G for the first time where he downl.... No wait
Where they video called other guy standing few feet away from him & also called him to test 5G voice call quality
Truly an iconic 5G demonstration joke. Video calls were introduced in 3G and government is demonstrating that in 5G
I've lost all faith since then...

Except for Jio, you still can't make video calls directly.

 

[AAK]

You can make video calls on Airtel too , directly
