@NMK3 , no need to write in two different threads, you will not get an answer any quicker, but we need more information, are you on pay as you go or contract? Where are you in the UK or abroad?
If abroad, did you first use your SIM card in the UK and make a chargeable call or text if on pay as you go? The SIM card has to first be activated in the UK in order for it to work abroad, and you would also need credit.
If in the UK, could you please check here, where you can register, report and receive updates:
