Signal

[JOVID2002]

I received a SIM a few days back and it still provides me with no signal so I cannot call my provider.

Have you topped up the Vodafone UK sim card @JOVID2002 

From How-do-I-activate-my-SIM. 

"I've just joined Vodafone on Pay as you go

1. Put your SIM into your device and switch it on – if you need help, find out how to insert a SIM
2. Wait for your phone to show it has signal and the Vodafone symbol – this can take up to 24 hours, but it's usually much quicker
3. Top up your phone and make a chargeable call" 

Is your phone unlocked or locked to Vodafone UK so it'll accept a Vodafone sim card.

Vodafone can also be contacted via Live Chat  and the Vodafone Social Media Teams- Contact-us-for-account-specific-queries.
