Unable to access WhatsApp without WiFi.

[TomLinda]

Since a visit to the UK earlier this month we have been unable to send or receive WhatsApp. Data roaming is on. It's a Samsung Z Flip 4

Hi @TomLinda  can you confirm you are not in the UK now ?

Also try this @TomLinda 

If it’s android try this
Sky Menu App or SIM toolkit,Roaming, Make sure this is set to Home.

[TomLinda]

Hi, I tried the Sky app and also the settings on the android however I can't see any option to set roaming mode to "home". Roaming is on and also data usage is on. 
thanks.

Do you see the SKY MENU APP or SIM TOOLKIT  @TomLinda  ? Are you in the UK ? Is your phone from sky ? 

[TomLinda]

I used the Sky menu app/ manage sim. 
I am  not in the uk, I'm in Ireland and only have a sim from Sky. 
where do I find the sim toolkit? 
the mobile/roaming/ data settings on the phone all look ok
