Hi ​@Ninjaeejit2014 

Have you tried the SIM card in another phone and see if it works?

Have  you activated your new SIM:-

If you are still having problems then your best option is to contact the Live Chat to discuss this:-

When you contact the Live Chat :-

Type ‘talk to a person’ in the dialogue box and this will bypass the unhelpful chatbot. 

Please be patient as the agents handle a few conversations at any one time so there will be a delay in connecting with an available agent and also any replies to your query.

Good luck x
