wifi dialling

[dongorgan]

I have a Samsung S10 with dual SIM. 
EE SIM is primary and set to default for calls, messages and data with a Vodafone PAYG SIM as secondary.

Problem is there are times when the EE SIM will not do Wi-Fi dialling even though this is set by default for both SIM cards which is a massive inconvenience as the EE signal in my home is not  great, however  the Vodafone PAYG SIM always seamlessly flips over to Wi-Fi dialling.

Hi @dongorgan 

Welcome to the community.

Does the WiFi connection show good WiFi signal when the WiFi calling doesn't work?

Hi Christopher,

The WiFi connection is optimal.
Funny thing is the EE SIM flipped to WiFi dialling within 5 mins of me posting.

VF may well have different VoWiFi parameters to EE, I'm not familiar with their current setup but EE's will - by default - only kick in when the RX levels fall below a certain level.

A good test/workaround is to enable flight mode - thus forcing no coverage - then enable WiFi manually. Does this work?

Hi Bristolian,

I normally enable flight mode as soon as I get home and switch manually to WiFi due to the poor mobile signal coverage in my house. This normally works, however there are times when the EE SIM will still not flip over to WiFI dialling whereas the VF SIM will always flip over. On this ocassion I even restarted the phone to no avail. As stated previously it did eventually flip over

To clarify - you had a "no mobile coverage" scenario, with good WiFi-connection and WiFi-calling enabled... yet it didn't kick in?

How recently has this been happening?

[dongorgan]

Correct!
This has been happening intermittantly for around a year now.
Massive inconvenience as sometimes I don't realise and end up missing calls.

Oddly enough the VF SIM always switches, so don't think it's an issue with the phone.

Hi @dongorgan 

Thanks for coming back to us. 

I would suggest getting in touch with our technical support team and they will get this looked into for you.

Hi @Leanne_T

When I go abroad I always use local WiFi with my handset in flight mode to avoid roaming charges.
I've noticed in this scenario the EE SIM never switches to WiFi dialling whilst the VF SIM does.
Is there some sort of geographical restriction for WiFi dialling with the EE SIM?

EE WiFi-calling is intended as a coverage-expansion service for use in the UK, and is not supported abroad.

It will sometimes work outside the UK, but you should expect standard roaming charges to apply.
