I've recently had a bunch of travel to the UK, Indonesia and India. My phone is a Nokia G60 5G which works pefectly on Skinny 4G whilst in NZ and I can make voice calls over WiFi or VolTE.

Australia - Just works.

USA - I was in transit so didn't do a lot of testing, but I did managed to get a 4G data connection.

UK - Voice calls worked but there is still excellent 3G coverage. In fact my phone would often drop back to 3G as 4G coverage is still unreliable near my parents.

Indonesia - If I had strong WiFi voice calls worked even though Spark/Skinny don't officialy support WiFI when roaming. On mobile I showed 4G or 4G+ but no VOLTE icon and often voice calls failed. We had better luck with my wife's Nokia G20.

India - again I show 4G+ on my phone and there don't appear to be any 3G networks here in Delhi. Voice calls only work if the phone can drop back to 2G or find a good WiFi network.

So what is other peoples experience with 4G roaming as this is very disappointing. I'm going to try and arrange a support chat with Skinny, but I'm generally not free during NZ biz hours.

@openmedia Do Skinny list on its website which handsets will work with VoLTE roaming?

I know 2degrees do

Edit: Further to this are you using an official handset provided by Skinny or a parallel imported handset?

If imported then Skinny could reject any official support

I hate to say it but Apple (iPhone 6s and above) have all carriers profiles worldwide profiles for VoLTE

This still relies on an agreement between the two carries to supports VoLTE roaming.

I am heading to the US next month so will find out if things have changed since I was there last year.

last time of was in the US to make calls/txts the handset dropped down to GSM but that is been shutdown 2nd of April 2024

It will be interesting to see if this is still the case or if ONENZ and AT&T/T-Mobile now have a VoLTE agreement...

Imported Handset from Amazon/Nokia in OZ as they're not selling the newer nokia devices locally.

VOLTE works perfectly in AU and NZ. It is US/UK/India where I'm having issues

And this device is widely available in both India and the UK

@openmedia does not matter if VoLTE works in NZ and AU

VoLTE roaming is not the same in all countries and as you are using a imported handset this will cause support issues

The first question I am guessing would be ' Did you try a supported handset from Skinny that is tested and approved '

Cause the handset is sold in UK & India has zero to do with it as well as you are not using a local SIM card. You are roaming which is a different kettle of fish altogether as the roaming network gets information from the home network

I know you are asking about Skinny VoLTe roaming but this quote shows how complex VoLTE roaming is

" Devices must be running the latest available software to support VoLTE Roaming. Minimum requirements as follows:

Samsung range Android 12

OPPO range Android 13

Article last updated on 12 May 2022 "

Just tried my spare phone - Nokia 7.2 Spark compatible phone bought in NZ from PBTech

Once again VOLTE works in NZ and OZ - Doesn't work here in India with a Skinny SIM.

Personally would not count on it being exactly the same in all markets without a very close look.

Either the Nokia 7.2 doesn't have VoLTE profile for India or there is no Roaming agreement for VoLTE in place

Tried an iPhone?

Trying to confirm VOLTE Roaming in India with Skinny, but no VOLTE = No voice roaming as 3g is turned off.

Don't use or have access to an iPhone.

Just had a quick look at the Skinny website no mention of VoLTE roaming in India

Can you let us know how it was confirmed that Skinny provide VoLTE roaming in India?

Just used my phones test screen to confirm IMS registration has failed - so No VOLTE.

Where are the details on VOLTE Roaming?

Basically with 3G being turned off a lack of VOLTE roaming = no voice when roaming which is ridiculous.

That is the way it was for a while in the US for NZ customers

I suspect they do not have a volte roaming agreement in place
