PAYG and in 4G area, am I getting 4G calling on PAYG?

Hi All

Noticed over last couple of months after mast upgrade when I talk to people on a 4G handset the sound quality is so much better like as if your on VoIP, but to a phone and landline or 3G- mobile user and it's back to typical phone sound quality?

I got 4G Nokia 1.3 sure it doesn't support 4G calling and on PAYG sure that doesn't either? can anyone confirm / answer this please?

Don't think I got Wi-Fi calling either but just noticed people with 4G phones sound so much better quality and as do I apparently a mate and I am trying to work it out?

Well I guess I am a Level 3 Thinker...!

Looking forward to replies and thoughts!

Thanks

Nick

You are correct in assuming that no wifi / 4g calling is available on PAYG.

The mast upgrade must have upgraded the rest of the hardware too.
