You said you were PAYG. But PAYG SIM cards can't make calls over 4G

@Jing Further info to my earlier post. I've taken a look and WhatsApp use in China is restricted to texts only, I believe. Alternatively, you and the people you want to reach in the UK can use Skype over Wi-Fi for free:

Skype is only free for freephone numbers and doesn't satisfy the chargeable call every 6 months requirement.

Skype to Skype over a Wi-Fi connection is free whether you use it on a phone or a laptop or a desktop.
